FREQUENTLY ASKED QUESTIONS
- Get to where you need to go faster and easier than on a regular bike. Depending on how you choose to ride, you can travel without significant effort at up to 20mph on some bikes and even up to 28mph on others.
- Climbing hills is a breeze. and we aren’t talking about the breeze from huffing and puffing.
- No sweat. Even though you can ride much faster, you won’t feel like you have to take a shower once you are there.
- Safer. That might seem counter-intuitive, since you can go faster than on a regular bike, but you also get an easier start from stopped positions, allowing you to get through an intersection steadier and quicker. When climbing steep hills with cars nearby you can FOCUS more of your energy on controlling the bike instead of propelling the bike.
- Easier on those joints. Use the electric assist to ease the pressure on your knees and hips.
- Staying together. You may have a riding partner that rides at a different pace than you. An e-bike can even out the pace for both of you.
- Ditch the car. The convenience, the ease and the speed of an electric bike make it an alternative to an automobile more often than a regular bike. A study by Portland State University shows that e-bike owners ride more frequently and farther than when they relied on their traditional bike. This was the case for all age groups.
- It’s FUN. Just try one and you’ll see. Or catch a friend coming back from their first test ride with a big smile on their face.
Do I need a license?
No. As long as the e-bike has a motor size of 750 watts or less (1000 watts in Oregon) and is programmed so that it can’t go more than 20mph without pedaling, there is no need for a license. No electric bike sold by Cynergy E-Bikes requires licensing. FYI – you must be at least 16 years of age to operate an e-bike in public places.
Where can I ride my e-bike?
First and foremost, make sure your bicycle with an electric motor is classified as an e-bike. The definition of an e-bike and rules on where to ride will vary state by state. For federal land the rules vary depending on the branch of government. For the most complete resource, check out PeopleforBikes.org
For Oregon, you can ride an e-bike on:
- Any bike lane on the street.
- Shared use paths that are reserve for bicycles and pedestrians
- For state parks, you can ride on paved trails that allow bicycles, but check with the individual park’s management for their rules for unpaved trails. It varies from park to park.
- Any trail where motor vehicles are permitted, such as unpaved forest service roads.
In Oregon, you must be at least 16 years old to ride an e-bike on public property. While most states have motor wattage limits of 750 watts, Oregon’s limit is 1000 watts.
- National Parks – opportunities are expanding, but check with the park.
- Bureau of Land Management trails – the trend is to allow e-bikes wherever non-electric bikes are allowed, but we advise you to check with BLM office that manages that trail.
- U.S. Forest Service – opportunities are expanding, but check with the Forest Service.
- Another resource for finding mountain bike trails where e-bikes are allowed is People for Bikes nationwide EMountain Biking Map.
What about theft?
As best as we can determine, e-bikes don’t get stolen with any more frequency than non-electric bikes. That’s most likely because people tend to lock them up better and because a bike thief needs to get a charger and a battery key to make the bike truly saleable.
The best ways to protect your bike from theft are:
- Get a high-quality bike lock. Cable locks are way too easy to cut. High-quality u-bolts and folding locks are better.
- If you are parking your bike in your garage, lock your garage. It’s probably the #1 location we’ve seen bikes get stolen from.
- When in public, lock your bike in a visible location.
Do I need special insurance?
Check with your insurance company. Some insurance companies do not treat e-bikes as bicycles, so you may need to get a rider added to your homeowners/renters insurance for theft protection. You can also check with two bicycle specialty insurers – Velosurance.com and Spokeinsurance.com.
Aren’t electric bikes heavy?
As one of our customers told us, “E-bikes might be heavy to lift, but they are heavenly to ride.”
Electric bikes are typically heavier than regular bikes. But the weight of any bicycle (electrical or non-electrical) is felt the most when climbing hills. The electric assist on an e-bike makes up for the additional weight many times over. Where weight does matter is if you need to lift the bike. That’s one of the many reasons why e-bikes are favored over electric scooters, which often weigh 150 pounds or more.
If you have to climb several flights of stairs to store your bike, we strongly suggest finding a more accessible storage location.
CHARGING, BATTERIES RANGE
Do electric bikes recharge when applying brakes or going down hill – like a hybrid car’s regenerative braking?
It’s rare and the concept doesn’t work very well. A few models of electric bikes include a feature to recharge the battery, usually while you are braking. In those cases the range of the battery can be extended 5-10%, while adding several hundred dollars to the cost. However, due to the design of the motors that provide regeneration, you’ll often find that the bike is harder to pedal if you are using the bike with the power off.
What is the range I can get from a single charge?
The biggest factor contributing to your range is whether you pedal or just use a throttle without pedaling, along with what level of assist you use. Cynergy E-bikes is a strong proponent of the synergy cynergy resulting from combining human pedal power with electric power, so we’ll tell you the expected range when you do both. With relaxed pedaling expect 22-50 miles on a single charge for most e-bikes. In some cases you’ll go even farther. We have bikes that are getting 80 miles on a single charge. Range will also be impacted by the battery capacity, the hills, wind and your size. Many electric bikes pedal easily as regular bikes. So you can extend the range even further by using little or no power on level surfaces and down hill.
How long does it take to charge an e-bike battery?
A lithium ion ebike battery that is fully depleted will take 3.5 to 6 hours to recharge. Batteries that still have a partial charge when you start charging will take less. In addition, the last hour or so of a charge is used to “top-off” the cells, and you don’t have to wait for that process to be completed. So some batteries can be 90% charged in 2.5 hours or less.
How many charges can I get out of a battery?
Most e-bike batteries sold in North America are lithium-ion, which will provide a minimum of 500 full charge cycles at which point the battery will hold about 80% of its original capacity. Some batteries can deliver up to 1200 charge cycles. If you recharge the battery when it is only 50% depleted, that counts as only 1/2 of one charge cycle. If you usually use your e-bike in pedal-assist mode, combining both pedal power and electric power, you can expect to go 10,000-30,000 miles before replacing your battery. That is a lot of miles on a bicycle.
How much electricity does it take to charge a battery?
Depending on the capacity of the battery, it will usually take 500-800 watt hours (0.4. 0.8 kilowatt hours) to charge the battery. Assuming a rate of 0.10/kWh, it will cost you 5-8 cents for a charge that will last you 20-80 miles.
MOTORS, SPEED PERFORMANCE
What is the difference between Class 1, Class 2 and Class 3 electric bikes?
This system of classifying electric bikes is being adopted by several states as a means of regulating electric bikes. The classifications are as follows:
- Class 1. is a bicycle equipped with a motor that provides assistance only when the rider is pedaling (thus no throttle), and that ceases to provide assistance when the bicycle reaches the speed of 20 miles per hour.
- Class 2. is a bicycle equipped with a throttle that can propel the bike up to a maximum of 20mph with the rider pedaling, and may also have the ability to achieve up to 20mph with the rider assisting, without the use of a throttle.
- Class 3. also known as a “speed pedal-assisted electric bicycle,” is a bicycle equipped with a motor that provides assistance only when the rider is pedaling, and that ceases to provide assistance when the bicycle reaches the speed of 28 miles per hour.
For all classes, the maximum power output is 750 watts (1 h.p.).
Several states, including our neighbor to the north, Washington, have adopted regulations that use this class system. Our home state, Oregon, has not yet done so.
Perhaps the most important aspect of this classification system is how some states are treating Class 3 e-bikes. While these bikes are permitted in bike lanes on streets, they can be restricted from shared use paths, such as those in parks and “rails-to-trails” paths that are designed to be shared by cyclists and pedestrians.
Should I buy a bike with a mid-drive motor or hub-motor?
They both have their benefits. Hub motors tend to be a little easier to operate if you are a less experienced cyclist, because they require less shifting of gears. Mid-drives tend to get a little better range for equivalent battery capacity, because you’ll get more efficiency by shifting. While theoretically you get better hill climbing with a mid-drive, you’ll usually find both types will climb just about any hill.
Finally, it’s usually easier to change a rear tire with a mid-drive.
But the real test of determining which type of motor is best for you is to ride both and compare.
What’s the difference between a cadence-sensor and a torque-sensor?
With a torque sensor, the power that is delivered is increased in proportion to the amount of pedal force the rider is applying. So as you pedal harder, the motor automatically delivers more assist. As you reduce pressure, you get a little less assist. It’s essentially amplifying whatever power you are applying to the pedals. You have multiple levels of pedal-assist, with each level representing a higher or lower amplification of your own power. A torque-sensor can feel more like riding a conventional bicycle than a cadence-sensor. It also tends to deliver power smoother.
A cadence-sensor, perhaps more appropriately called a crank-sensor, delivers a uniform amount of assist at each assist level, regardless of the amount of pressure you are applyng. It is activated just by getting the crank turning. Because a cadence-sensor is not reading your pedal pressure, the power delivery is not quite as smooth or “bike-like”. But it’s fairly easy to adapt your use of the controls to smooth out the power delivery. Some people prefer a cadence-sensor because it tends to provide a great sensation of power without applying much pedal pressure.
The best way to know which type of pedal-assist is right for you is to try them both.
How fast can an electric bike go?
If you are pedaling, you can go as fast as you are able to pedal it. However, most bikes stop providing electric assist while pedaling at 20 mph (Class 1 and Class 2 ebikes). Some will provide assist going at speeds up to about 28 mph (=45 kilometers per hour – Class 3 ebikes.)
How important is motor wattage? (also. I’m really big, so don’t I need a 1000-2000 watt motor? or. I want to go fast, so don’t I need a lot of wattage?)
The benefits of a high wattage motor are very overstated. A street legal e-bike in Oregon can go only 28mph, and only 20mph unless you are pedaling (and we recommend pedaling). You’ll be able to get that with even some 250 watt motors.
With a properly designed e-bike and e-bike motor, you’ll find that you get far more power than you need with 500 watts or less. There are many 250 watt motors that deliver as much torque as motors that are 500 watts or higher. The design of the motor and the gearing of the bike are far more important than the wattage of the motor.
Higher wattage correlates with higher power consumption, so using a higher wattage motor means you’ll need a bigger battery to go the same distance. The most expensive part of your e-bike is the battery, thus a larger motor, requires a larger battery which leads to higher cost.
As for hauling a lot of weight, we have several 300lbs customers that do fine at 250-350 watt motors.
Can I ride an e-bike as a regular bike. without the electric power?
Yes. And it is easy to switch back and forth. For example, you might want to use the power only when you are going up hills.
Do I have to pedal?
It depends on the bike. Some electric bikes sold in North America allow you to operate by simply turning the throttle without pedaling. Europeans have stricter rules, requiring that you pedal. which we support. If you think you’ll get by without pedaling, think again. Even for e-bikes that have a throttle, you’ll need to pedal when going up long, steep hills, although you won’t have to pedal hard. Pedaling is more fun, extends the range of your battery, extends the life of your motor, and extends your own life too.
Is servicing an e-bike any different than a regular bike?
Look at an e-bike as being comprised of two groups of parts – mechanical and electric.
- Mechanical parts are the same parts that you’ll see on non-electric bikes. Servicing mechanical parts can be performed at any bike shop. You might find that your bike parts might wear a little faster than on a non-electric bike – especially brake pads, chains, cogs and tires. But that’s because most people put many more miles on their e-bike. There is some basic maintenance that you can do on your own, like keeping your tires properly inflated and lubricating your chain. For some basic bike maintenance tips, check out our recommended maintenance videos.
- The electrical parts don’t require any maintenance. If you do run into a problem with an electrical part, you’ll want to go to a shop that has some expertise in servicing e-bikes. While not really a maintenance task, you do want to make sure that the battery keeps some charge in it. If you don’t, it might discharge to a point so low that you can’t charge it anymore, thus killing your battery – an expensive mistake to make.
Cynergy E-Bikes has a complete service department for both mechanical work and electrical work, with expertise servicing electrical parts for from many different e-bike brands.
CLIMATE AND WEATHER
How much will I reduce my carbon footprint if I use an ebike instead of a car?
Our favorite question! In Oregon, which depends on hydropower and wind more than coal and gas, it takes the carbon footprint of over 60 e-bikes to equal the carbon footprint of one single occupancy, gasoline-powered car. In states that depend more on coal, it might be around 20-30 e-bikes compared to one car. No matter how you calculate it, even though an ebike uses electricity that might come from fossil fuels, the amount of CO2 emitted compared to a car is miniscule.
What about leaving my electric bicycle out in the rain?
The motor and battery are sufficiently sealed to be protected from the rain. However, we do suggest that if you are carrying your bike on the back of a car and rain is in the forecast, that you place the battery inside the car. Driving 70mph in a downpour with the battery exposed is like pressure-washing your battery. That’s a lot different than riding your bike in the rain.

If you’re shopping for your first ebike or electric scooter, you might be a bit confused by the numbers you see on the spec sheet. What exactly is a watt-hour (Wh), and how is it different from an amp-hour (Ah)? Does voltage matter? How big of a battery do I really need?
With the help of some basic physics and arithmetic, we’re here to help you make sense of these numbers.
Which spec tells me the battery capacity?
When you look up an electric bike or escooter, chances are you’ll come across a variety of numbers related to the battery. These three are the most common ones: volts, amp-hours, and watt-hours.
Watt-hours (again, that’s ‘Wh’) are the most useful unit when it comes to energy capacity. If you’re looking to compare the battery sizes for two rides, you’ll want to look for the watt-hour rating on the spec sheet.
Tickets are officially sold out
But there might be some last-minute spots available
Assuming honest specifications, the bigger the watt-hour rating, the bigger the battery — longer the range.
I don’t see a watt-hour rating, only amp-hours and volts. Help!
While most ebike companies these days show battery ratings in watt-hours, many electric scooter companies still stick to volts and amp-hours. Worry not, my friend. Finding a battery’s watt-hour rating from volts and amp-hours is the simplest of multiplications. Here’s the formula for you:
That’s it. By the same token, you can find a battery’s amp-hour rating by dividing the watt-hour rating by the voltage. Or divide the watt-hours by amp-hours to find the voltage.
Keep in mind the above formula is an approximation, as a battery’s voltage will vary during use. But for all intents and purposes, it’s the easiest way to compare battery capacity among various ebikes and escooters.
The ebike I’m looking at has a 250W motor. How does that relate to range?
The motor’s wattage on its own doesn’t tell you anything about the range. Although they are related, watts are distinct from watt-hours.
The former is a unit of power. When it comes to ebikes and escooters, that basically means how much power the ebike is able to draw from your battery over an extended period of time.
A higher-wattage motor higher-wattage motor can theoretically go faster or climb up steep hills for longer. It will also drain your battery faster at its maximum demand, but a motor’s wattage isn’t a fixed value — it depends on how hard you are pushing the motor. The figures given by manufacturers are averages.
The watt-hour, on the other hand, is a unit of energy (or energy storage). It basically tells you what sustained wattage is required to drain the battery in the span of — you guessed it — an hour.
In other words, if your motor is using an average of 250W, it would take about one hour to drain a 250Wh battery, two hours to drain a 500Wh battery, and so on.
But again, you shouldn’t rely on watts to estimate range because the motor’s wattage is rarely constant. They usually can ramp up to wattages beyond their official rating; that’s why you’ll see some companies list their “peak wattage” along with the standard or “nominal” wattage.
How big is big?
As we’ve noted, the amount of energy used by a motor can vary significantly, but there are some general guidelines you can keep in mind.
Typical ebike and scooter batteries tend to hover around the 400-600Wh mark. Lightweight scooters and ebikes tend to be closer to the 300Wh mark, while heavier, powerful models tend to be closer to 1000Wh — or more.
How far those batteries will take you depends largely on how you use your bike or scooter. Higher assist or speed settings will naturally use more energy, but things like the type of motors, wheels, or sensors can affect range as well.
Lots of talk about watts, but what about volts and amp-hours?
For most people, knowing the watt-hour rating says everything you need to know about an electric vehicle’s battery capacity. Still, you might be curious how volts and amp-hours come into play. It can be a little confusing, so keep in mind the following is all a simplification.
The most common voltages on the market these days are 36V, 48V, and 52V, although you’ll occasionally see lower or higher ratings too (the latter especially in the DIY market). All else being equal, a higher voltage battery will usually be able to output higher power and maintain high performance at low battery levels.
Higher voltage batteries will also use less current at a fixed power rating, which theoretically translates to less heat and damage to the motor for a given performance level. On the other hand, higher voltages can technically increase the risk of electrocution. That’s partly why you rarely see commercial ebikes go beyond 52V.
As with so many facets of technology, the implementation often matters more than the actual specs. Some of the best hill-climbing ebikes I’ve tested have used 36V motors, while I’ve had weaker pedaling experiences out of some 48V ebikes. In my experience higher voltage batteries are usually better than lower voltage ones.
Despite remaining a common specification, amp-hours is frankly a pretty useless metric for most ebike and scooter riders.
Although it is typically used to denote battery capacity, it should only be used for comparison on ebikes with identical voltages. A 24V 20Ah battery will have significantly less range than a 52V 15Ah one.
If you want to know an electric bike or scooter’s realistic range, looking at the watt-hours is still your best bet.

Discover Whether 350 Watts Is Enough for an Electric Bike (eBike)
If you’re looking to purchase an electric bike, one of the most important considerations is power. How much power do you need? Is 350 watts enough for an electric bike? As an e-bike expert, I’m here to answer that question.
There are many variables to consider when trying to determine if the amount of power supplied by a 350-watt motor is sufficient for your needs. These include rider weight, terrain type and terrain grade, battery capacity, and the desired speed range. All of these factors should be taken into account when deciding if 350 watts is enough for your e-bike.
Ultimately, it’s up to you to decide if a 350-watt motor will provide enough power for your e-biking needs. But with this article as a reference point, you’ll have a better understanding of how much power you’ll need and be able to make an informed decision about whether or not 350 watts is enough for your e-bike.
Power Requirements For eBikes
The power requirements for an e-bike depend on the type of riding desired. For example, mountain biking requires more powerful motors than a leisurely ride around the neighborhood. Generally, electric bikes use between 250 and 500 watts of power for a comfortable ride. However, many riders opt for a higher-powered motor to keep up with traffic or go faster on hills.
When selecting an electric bike, it’s important to consider the terrain you’ll be riding on and the speed you want to reach. If you’re looking for more speed or plan to take your e-bike off-road, you’ll likely need at least 350 watts of power. On the other hand, if you’re looking for a leisurely ride at lower speeds, 250 watts should be enough. Now let’s discuss the components that make up an e-bike system.
Components Of An E-Bike System
Power is absolutely essential when it comes to e-bikes! With so many components that make up a functioning electric bike system, understanding how each part works and the wattage required for them to function properly is essential – and with 350 watts, you’d better believe there’s enough power to go around.
A typical e-bike system consists of a battery, motor, controller, throttle, and display. Each of these components requires varying degrees of wattage to function, but rest assured, they can all be powered by 350 watts! The battery needs the least amount of wattage at roughly 250 watts, while the motor requires 300 or more, depending on the size and type. The controller is responsible for controlling the motor’s power input, and it needs about 50 watts. Finally, the throttle and display require 25 watts each.
With 350 watts as your power source, you can be sure that your e-bike will run smoothly with no difficulty! You’ll never have to worry about running out of juice when you’re out riding since 350 watts is more than enough to keep your system running optimally.

Advantages And Disadvantages Of 350 Watts
The power of an e-bike is determined by the wattage of its motor. 350 watts is a common output for many e-bikes, but it isn’t always enough for everyone’s needs. It has both advantages and disadvantages.
On the plus side, 350 watts offers a good balance between performance and efficiency. It can provide decent torque and speed without draining too much battery power, so it can be great for casual riders who don’t need to go particularly fast or far. Additionally, it often comes with a lower price tag than more powerful motors, making it an attractive option for budget-conscious buyers.
On the other hand, 350 watts may not be enough for advanced riders who want their bike to move faster or carry heavier loads. It also won’t provide as much range as higher wattage motors, so those wanting to cover longer distances may need to look elsewhere. Overall, 350 watts is a decent choice if you don’t need extra power or range, but if you do then you’ll need to look at alternative solutions that can increase your e-bike’s output.
Alternative Solutions To Increase Power Output
While 350 watts may be a sufficient power output for some electric bikes, others may require more. Fortunately, there are alternative solutions available to increase the power output.
One of the most common solutions is to upgrade the motor and battery components. This can include increasing the motor’s wattage or using a higher voltage battery. Alternatively, adding additional batteries in parallel or series configurations can also help increase the total power output of the bike without having to upgrade components. Additionally, installing an aftermarket controller with adjustable settings can allow riders to fine-tune their setup and maximize its potential performance.
Overall, upgrading components or installing an aftermarket controller are effective ways to increase the power of an electric bike without having to invest in a more powerful motor or higher voltage battery. The end result will be a bike that produces more power and offers an improved riding experience.
The question of whether 350 watts is enough power for an e-bike has been a fiercely debated topic. As an e-bike power expert, I can confidently say that this depends largely on the components of the system and the desired performance.
Overall, while 350 watts may be enough to get you around town or on light trails, if you’re looking for speed and power, then it’s probably not enough. However, with a few upgrades to the battery and motor components, you can greatly increase your bike’s power output. This will allow you to tackle tougher terrains with greater ease and efficiency.
Ultimately, only you can decide what kind of e-bike setup will best suit your needs. With the right balance between power and efficiency, 350 watts could be all you need to take your e-biking experience to the next level!
What Does 750 Watts Supposed to Mean for E-bikes?
E-bikes are becoming more popular by the day, and with that, the wattage of these machines is also increasing. So what does 750 watts actually mean for an electric bike ? Are they now powerful enough to take on regular bikes? When it comes to electric bikes, 750 watts is a big number. That’s the maximum power that an electric bike can produce, and it’s important to know what this number means for you. This article will break down what 750 watts means for electric bikes and help you decide if a power level that high is right for you. Let’s get started.
What does Watt Mean for an Electric Bike?
Innovative industries often introduce new terminology. One example is the automobile industry, which introduced terms such as carburetor, throttle, quarter panel, differential, and many more to describe the technology. Similarly, there are certain terms and ideas that may be unfamiliar when discussing electric bikes.
The concept of power is well-known in the realm of transportation. Power is a measure of work output and how quickly you can complete that work. Generally, more power equates to increased acceleration capabilities or the ability to tackle steep inclines without a decrease in speed. In the case of cars and motorcycles, power is typically quantified in horsepower, and the distinction between a motorcycle with 5 horsepower and one with 200 horsepower can be straightforward.
When it comes to an electric bike, the unit of power output often used is not kilowatts but watts, typically ranging from 250 to 900 watts. To put that in perspective, this is roughly equivalent to 0.3 horsepower to 1.2 horsepower. Much like traditional vehicles, an electric bike with a higher power output is able to accelerate faster and can handle greater loads while climbing steep inclines.
Calculating the Power of an Electric Bike
Now let’s get to some school-level basics and have a clear idea of this concept for your e-bike. In physics, Watt is the SI unit of power. It is defined as one joule per second. A watt can be thought of as the rate of energy transfer over a time interval and is usually quoted in terms of power output or work done. The higher the wattage rating on an electronic device (E-bike motor in your case), the more powerful it will be.
The general equation for Watt is: Watt = Voltage × Current
For example, an E-bike motor powered by a 24V battery that is supplied with approximately 15 amps of current would be around 360 watts. We are looking at an E-bike with an estimated power of 360 watts in this case.
The wattage rating on an electric bike is a measure of the power produced by the motor. However, it’s not a measure of how fast the bike can go. The wattage rating is important because it determines the range of speeds that the bike can travel at. Most electric bikes have a wattage rating of 250-750 watts or higher. A 750w fat tire ebike can travel at speeds up to 20 mph, which is about as fast as most people would want to go on an electric bike.
What is a “Peak” Watt?
Peak wattage is the highest wattage that an electric bike can produce for a short period of time. This is usually achieved when the rider is sprinting or when the bike is going up a very steep hill. It is important to note that peak wattage cannot be sustained for long, and will eventually decrease as the bike pedals more.
Is Power Determined by Battery?
It is generally confusing for people but the truth is that the power of an e-bike is not determined by battery. The electric motor is what provides power to the bike. It is typically a small, portable unit that is powered by a battery. The electric motor is what makes the bike go. It is important to know how the power is determined on these bikes in order to make an informed purchase.
What Exactly Does 750 Watts Mean for an E-Bike?
Now let’s try to understand the concept of 750 watts in a simpler way. To understand the meaning of power in relation to human effort, we can examine the number of watts required to ride a regular bicycle at different speeds. A normal rider typically cruises at around 9 mph and expends about 30 watts, similar to the energy used while walking.
However, at a speed of 20 mph, which requires overcoming significant wind resistance, an average of 220 watts is needed, which most non-professional riders may find, challenging to sustain. When climbing a 10% incline at a moderate pace, 150 watts are required, which would result in significant exertion for most riders.
On the other hand, professional cyclists at the level of the Tour de France are capable of producing 400 watts for an hour and even more for short sprints to the finish.
In the context of a normal or a fat tire electric bike, 750 watts refers to the power output of the electric motor. This is the amount of power that the motor can deliver to the bike’s drivetrain in order to assist the rider in pedaling. The motor is powered by a battery, which provides electrical energy to the motor. The power output of the motor, measured in watts, determines the speed and torque of the bike, and thus how much assistance the rider receives while pedaling. 750 watts is generally considered a high power output for an e-bike motor and can result in faster acceleration and hill-climbing ability.
It’s also important to notice that in some countries or areas, there are regulations on the maximum power output for e-bike motors; 750w could be above that limit making it illegal to use it in certain places. In the US, electric bikes are limited to 750 watts, allowing for a level of assistance equivalent to that of a professional cyclist.
In conclusion, 750 watts is a measure of the power output of a 750W ebike motor. It refers to the amount of power that the motor can deliver to the bike’s drivetrain to assist the rider in pedaling. The higher the wattage, the more power the motor is capable of producing, resulting in faster acceleration and better hill-climbing ability. However, it’s important to keep in mind that a higher wattage does not always translate to a better e-bike and other factors such as battery life, weight, and overall design should be taken into account before making a purchase.
