It’s worth reading the full review, but to sum up their thoughts on the Defender-S, check out their handy Pros and Cons chart.

Defender-S Description

If you need an electric mountain bike with incredible hill-climbing and towing capabilities, the Defender-S is for you. This model features dual 750W motors.

The heavy-duty full-suspension Defender-S frame is handcrafted from 6061 aluminum alloy, giving the bike incredible strength. It is offered in 17 and 19 frame sizes, so even riders as short as 5′-5 can enjoy riding the Defender-S. The frame is offered in stunning matte black and gorgeous grey finishes.

aostirmotor, s18-1500, tire, mountain, electric

The suspension components on the Defender-S include the RST Guide suspension fork, which offers 75mm of travel and mechanical lockouts; and the DNM A0-42RC rear absorber, which feature a dark hard-anodized AL-7075 ∅10 mm ( 0.39”) damper shaft, adjustments for rebound, lockout and high pressure, and delivers up to 190mm of travel. Cables are threaded through the frame for a clean design. The battery is integrated into the downtube portion of the frame, with the option for a second battery added on top of the downtube.

The Defender-S has 5 levels of pedal assist, allowing you to finely adjust how much power the motor puts out. It also features a thumb throttle, which allows for riding without pedaling (very stealthy). The Defender-S also features a 9-speed Shimano Alivio derailleur, providing smooth, reliable and fast shifting action, the elimination of unwanted chain movement and an end to ghost shifting.

The 48V/14Ah battery on the Defender-S is located within the downtube, providing an added level of stealth and aerodynamics to the frame. This battery, which is packed with Samsung cells, can be upgraded to 48V/17Ah. And if you really want to extend the range of your ride, there is an option to buy a second battery with 48V/14Ah or 48V/17Ah specs, which mounts on top of the downtube. The controller adjusts the draw from each battery automatically based on voltage and demand. The range these batteries are capable of achieving will vary based on a number of significant factors, including terrain, load, and demand. Please use our Ebike Range Calculator to estimate your expected range per charge.

The Defender-S is a very capable fat tire electric hunting bike, designed especially for natural trails and rugged off-road terrain. You will appreciate the highly responsive speed sensor, that will make slow technical riding feel natural and intuitive. This electric mountain bike is sure to be a favorite of hunters, allowing you to travel great distances to follow game, monitor cameras, and visit remote watering spots. The Kenda 26” x 4” fat tires were designed for use with bikes and feature dense 30 TPI casings, wire beads and K-Shield protection.

Kenda’s first line of defense since 1995: a layer of light, flexible rubber containing aramid and ceramic particles inside the tire, under the tread area only. This has been designed to prevent punctures and increase tire life.

These tires will provide excellent traction and stability on uneven and gravely surfaces, and can be ridden on snow and sand. For a wider footprint, you can deflate the tires down to 5 psi, or pump them up to 30 psi when you ride on paved surfaces and want a more responsive feel and performance.

When it comes to stopping with authority, the Defender-S does not disappoint. It features a hydraulic brake system with 180mm stainless steel rotors front and rear, and automatic brake/motor cutoff sensors, so you will never risk motor acceleration during braking.

Electric bikes are an excellent form of transportation, even a highly specialized ebike like the Defender-S. They can be ridden in bike lanes and other areas where cars are prohibited; they have zero emissions and are therefore a greener, ecologically-friendly alternative to cars.

How Fast Can a 1500-Watt Ebike Go? Find Out The Speed Potential

Apart from this, it’s also important to know the legal requirements for 1500w ebikes in your country and whether you are allowed to ride such bikes in your city, and so on.

The purpose of this article is to explore the 1500w electric bike speed potential for adults, along with important factors that can influence it, and safety considerations.

So, let’s dive in and find out how fast can a 1500W electric bike really go! Is this ebike faster than a 1000w ebike’s speed?

What Does a 1500W Electric Bike Mean?

An electric bike that has a motor generating 1500 watts of power is called a 1500-watt ebike. 1500-watt bikes are one of the highest-wattage e-bikes available on the market. These e-bikes are designed to give riders thrilling and adventurous riding experiences.

As you already know that higher wattage ebikes offer higher speeds and vice-versa. So the 1500w ebikes are. Also, they have more than 100 NM torque and higher acceleration compared to lower-wattage e-bikes.

These bikes perform excellently on hills and reach a much higher speed of about 40-43 mph than lower-watt ebikes because of their high motor wattage. However, this speed is lower than the 2000w ebike top speed.

How does a 1500-watt motor work on an e-bike?

Almost all e-bike motors work the same way. A 1500-watt ebike motor starts assisting when using throttle mode or pedal assist mode. Since this motor is very powerful and capable of giving much higher wattage and speed to the e-bike.

Mainly there are two kinds of e-bikes motor used in 1500w ebikes i.e., Hub motors and Mid-drive motors. Mid-drive motors are more powerful than a hub motor as their weight is centralized providing more torque.

What voltage battery to use on a 1500w ebike for the best performance?

It is very important to use the right size electric bike battery which is compatible with your 1500w motor if you want to achieve its maximum speed for longer distances. If you get the wrong voltage battery, your motor may not work properly or get damaged.

So before you choose a battery for a 1500w ebike, make sure to check the power rating, which is given in voltage. Make sure your battery’s voltage is equal to the motor’s required voltage.

For a 1500w ebike, it is recommended to use a 1500 WH battery i.e., 48V 32 Ah or 52V 30Ah lithium-ion battery to get the best performance. Usually, the higher the voltage of the battery, the faster the bike will run but don’t use much voltage.

Who should ride a 1500w ebike?

Electric bikes with 1500-watt motors are designed for all those riders who like more thrilling, high-speed adventure rides on all types of terrain or roads. You should ride this electric bike if you want the best performance and a faster speed of 40 to 45 miles per hour or more on flat roads and hilltops.

If you are a beginner, don’t ride a 1500w electric bike as it is very fast making it unsafe for newbies. Also, a rider needs a license for riding more than 750w electric bikes. As well as they are heavy and expensive.

Pros and Cons of Riding a 1500-Watt Electric Bike

Before you get a 1500w electric bike, you must know the pros and cons of a 1500-watt electric bike:

Pros of riding a 1500W e-bike

  • The biggest advantage of riding these electric bikes is that they have very high motor power, which gives the rider high speed, torque, and acceleration.
  • Comes with two or more pedal assistance options, which give the rider freedom to choose how much they want to pedal and how much electric assistance they need for their ride.
  • These bikes are well preferred and liked for making riding a more thrilling and adventurous experience for the rider and helping to relax and calm the mood.
  • Very powerful and give good performance on all types of terrain, on flat roads or smooth terrains, and for riding on top of hills or rough terrains with good and fast speed.
  • Great fit for long rides as they have a much higher battery capacity, which makes them ideal to travel to another city or out of town.
  • Eco-friendly as they don’t use any fuel, which can lead to global warming, and they are quiet, meaning they don’t make unnecessary noise while riding them.
  • Built using high-quality materials and have thicker tires, which makes riding this bike in bad weather on rough terrain easy and gives more stability to the rider.
  • Another advantage of these electric bikes is that they are great for heavy riders too, unlike other low-wattage ebikes, and they are strong enough to carry heavy luggage on a bike as well as give good speed.

Cons of riding a 1500W e-bike

  • These electric bikes are more expensive than low-wattage electric bikes, and because of that, many people don’t like investing this much in an electric bike and go for affordable bikes.
  • The maximum speed of this bike exceeds the legal limit (28 mph), hence you need a license and all documents that a motorbike needs.
  • Because of their high speed, these bikes are not easily controlled by beginner riders or new riders and may lead to an accident.
  • Much heavier than low-wattage e-bikes because they have been built using heavy metal components and materials.
  • The ebike battery gets discharged quickly because of the higher-wattage motor.

How Fast Does a 1500W Electric Bike Go?

As I have already mentioned that ebike speed depends upon many factors such as the type of motor, the terrain you ride on, and the bike type. Let’s see how fast is a 1500w ebike on various cases:

1500-watt ebike hub motor top speed

As we discussed above, hub motors are present in the hub of a wheel. These kinds of motors are cheap, easy to replace, and easy to repair. These motors can easily fit in any bike frame.

When it comes to its maximum speed, electric bikes with 1500-watt hub motors generally give a top speed of 35 miles per hour or 56 km/h on plane roads and this speed reduces to 20 mph while climbing hills.

1500w ebike mid-drive motor top speed

As we discussed above, mid-drive motors are placed in the middle or center of an e-bike (attached to the crank). These kinds of motors are known for giving better performance and torque compared to hub motors.

Therefore, 1500-watt mid-drive motors generally give a top speed of 40 miles per hour or 64 kilometers per hour and this speed reduces to 25 mph while climbing hills. Make sure to follow all the traffic rules.

1500-watt electric mountain bike top speed

Electric Mountain bikes are also known as “SUV Ebike” These bikes are designed specifically for adventures, hunting in forests, and climbing hills. That’s why their build quality is very heavy making them perfect for off-roading.

Such electric bikes with a 1500-watt motor run at a top speed of 32 mph on hills or 50 km/h. However, this speed may vary due to various factors, be with me to know them.

Factors Affecting the Speed of a 1500w Ebike

There are so many factors that can impact the speed of a 1500-watt electric bike and reduce/increase the bike speed and they are:

Ways of riding

The way the rider rides the e-bike also affects its speed. If a rider is using the bike’s brakes frequently, it will reduce the speed of the e-bike as well the battery will be discharged quickly.

Type of terrain

The place or road where you are riding a bike can also impact the 1500-watt e-bike speed. If you are riding the bike uphill, you will get less speed, whereas if you are using the bike on smooth terrain or downhill, you will get a better speed.

Battery voltage, charging level quality

If your 1500w ebike is not paired with a correct voltage battery, you would not get its top speed (45 mph). Generally, a 1500-watt ebike is equipped with a 52v or 60v lithium battery.

Always keep your ebike battery charged otherwise you would get less speed because a low-charged battery has a lower voltage. Apart from this, the quality of the battery affects the speed, If the battery has some problems, it will reduce the bike’s speed or may catch fire in some cases.

If you want to improve the battery performance and increase its lifespan, always charge an ebike battery to 80 percent level.

Weight on bike

The weight of the rider and luggage also impacts the performance and speed of the 1500 watt electric bike. If a rider is very heavy as well as carrying heavy luggage on the bike, it will reduce the speed of the e-bike.

Environmental conditions

External environmental conditions can also affect the 1500w ebike top speed. If there is a strong wind while the rider is riding or if the rider is riding in an extremely cold environment, it will reduce the performance and speed of an e-bike.

Legal Restrictions on 1500W Ebike Speeds

It is very important and essential to understand the electric bike riding laws and restrictions in your state or town. In the United States, there is a law that says that class 1 and 2 electric bikes can be ridden up to 20 mph.

Class 3 bikes (up to 750 watts) are limited to being ridden up to 28 mph. There are 6 states (Georgia, Kansas, Minnesota, Oklahoma, Oregon, and Virginia) that allow ebikes of up to 1000 watts.

There are only two states Florida and Mississippi have no maximum power limit for electric bikes. So what about a 1500w electric bike, will it be considered an ebike or an e-motorbike with pedals?

Except in Florida and Mississippi, 1500w electric bikes will be considered electric motorbikes because of their high motor wattage and a top speed of up to 45 mph.

That’s why there is a legal restriction on riding these bikes in the United States without permission from the authority (registration number, license, and insurance).

All riders must follow riding laws and rules given by states to ensure their safety. Here are some rules for riding an ebike:

  • Riders must educate themselves, understand the laws and restrictions, and follow them while riding an e-bike.
  • In 8 states of the US, a rider must be at least 14 years old to be able to ride, and in 6 states, above 15, and in 15 states, above 16. Source
  • You must wear a helmet while riding a class 3 or any ebike having a top speed of above 20 mph.
  • In most states of the United States, class 3 e-bikes are not allowed to be ridden on sidewalks and bike paths.

Conclusion on The 1500 Watt Electric Bike Top Speed

Overall, the speed of a 1500w ebike is faster than 1000w ebike speed which can be a thrilling experience for those who enjoy a fast-paced ride. These bikes have a higher top speed of about 40 to 45 mph.

So, it’s crucial for you to ride responsibly and stay aware of your surroundings to ensure a safe and enjoyable ride because 1500w ebikes come with their own risks and responsibilities, it’s important to follow traffic rules and wear protective gear to stay safe.

If you are a beginner, you should not ride this bike as it is unsafe for you.

Continue reading to learn about the benefits of owning a 1500-Watt electric bike.

Why Ride a 1500 Watts Electric Bike?

An electric bike is an excellent alternative to both the traditional bicycle and gasoline-powered vehicles, as it allows high-speed transportation to be possible without harming the global environment.

Besides being a cost-effective, eco-friendly, and highly durable form of transport, an electric bike can do so much more once high-wattage battery power it.

Multiple electric bike brands have designed and manufactured strong and sturdy electric bikes capable of handling the power generated by a 1500-Watt high-power battery.

The robust build of these electric bikes makes them significantly more expensive than other low-wattage electric bikes.

over, owning a 1500-Watt electric bike can offer some unique additional benefits that lower-wattage e-bikes cannot.

Some of the benefits of owning and riding a 1500-Watt electric bike are as follows:

High Speed

The greatest benefit that comes from owning a 1500-Watt electric bike is the phenomenal speed it can offer. Not many electric bikes can reach top speeds as high as these e-bikes.

The table below summarizes the top speeds offered by different-sized e-bike battery packs to make a clearer comparison between the speed of a 1500-Watt e-bike and other lower-wattage electric bikes.

The Electric Bike’s Battery Wattage Respective Top Speed of the Electric Bike
250 Watts e-Bike Battery 15 miles per hour
500 Watts e-Bike Battery 20 miles per hour
750 Watts e-Bike Battery 20 to 24 miles per hour
1000 Watts e-Bike Battery 28 to 38 miles per hour
1500 Watts e-Bike Battery 40 to 43 miles per hour

As demonstrated above, the speed offered by a 1500-Watt electric bike is considerably higher than most electric bikes in the market.

As a result, riders can enjoy the needed dose of adrenaline while enjoying the feeling of the air gliding against them.

Many electric bike riders claim that riding at high speeds helps them improve their mood, clear their mind, and feel refreshed after an exhausting day at work.

Additional Modes of Pedal Assistance

All pedal-assist electric bikes come with at least three modes of pedal assistance. This allows the rider to choose how much they wish to pedal and the electrical assistance they require from the e-bike’s battery to complete their journey.

Most 1500-Watt pedal-assist electric bikes come with two additional modes of assistance, resulting in five modes or levels of pedal assistance.

The lowest or first mode of pedal assistance requires continuous pedaling from the rider while offering the minimum level of electrical assistance.

In this mode, the e-bike’s speed primarily depends on the rider’s ability to pedal the bike.

The highest or fifth mode of pedal assistance requires little or no pedaling from the rider and allows them to enjoy a high-speed electric bike ride with uninterrupted momentum.

Having five different modes of pedal assistance allows the rider to gradually increase their e-bike’s speed, which helps make the 1500-Watt e-bike’s ride much safer.

A Thrilling Bike Ride

The electric bike we know today was initially designed to be the technologically upgraded version of the traditional bike we all have grown up riding.

However, with its ever-growing global popularity, a significantly large majority of the consumers voiced their demand for faster and more adventurous electric bikes. Hence, the 1500-Watt electric bike was introduced.

This highspeed e-bike may not be for everyone; however, for people looking to experience a thrilling and adrenaline-pumping e-bike ride without negatively damaging the environment, there could not be a better e-bike.

The 1500-watt electric bikes are used in bike racing and mountain biking sports.

Helps Cover Greater Distance

The incredible 1500-Watt electric battery packs have an equally impressive charge storing capacity. This allows the e-bike to offer a much higher range on all terrains.

As a result, these electric bikes allow the riders to cover a more significant amount of distance in less time.

Great For Traveling Longer Distances

Since 1500-Watt electric bikes have the battery capacity and traveling range to cover longer distances, they are ideal for when a person has to travel out of town, to another city, or to a far-off, remote area.

The large-capacity electric bikes do not run out of battery charge as quickly, so the rider does not have to worry about looking for a public charging station during their trip.

Cost-Effective than Similar High-Speed Gasoline Bikes

People who still prefer to ride gasoline-powered motorbikes over electric bikes usually do this because they need the speed a combustion engine can offer.

These people do not know that switching to a 1500-Watt electric bike will allow them to go at similarly high speeds while offering multiple other benefits.

One key benefit is that riding and recharging a 1500-Watt electric bike is much more cost-effective than refueling a same-sized gasoline-powered vehicle, especially with the current gas prices.

Hence, owning a 1500-Watt electric bike will allow a rider to enjoy a cost-effective bike ride without having to compromise on speed or acceleration.

Strong Enough to Carry Heavier Weights

1500-watt electric bikes are designed to have a strong and sturdy body made from steel to perform under the influence of a powerful 1500-Watt battery.

The electric bike’s strong build is excellent for a high-speed bike ride and allows heavier riders to enjoy an e-bike ride without worrying about the bike’s limits.

Thicker Tires for Rougher Terrains

The tires of a 1500-Watt electric bike are designed to be thicker and wider to pull the heavy weight of the strong and bulky e-bike.

Such tires help increase the electric bike’s stability while allowing riders to experience riding over more challenging terrains such as a mountain or a hilltop.

Although, in theory, a 1500-Watt electric bike should be able to offer a top speed of 40 to 43 miles, this is not always the case.

The actual speed that an electric bike can offer, regardless of its high-wattage battery pack, will depend on multiple factors.

Some of the factors that will always influence the 1500-Watt electric bike’s speed and performance are as follows:

  • The total weight the 1500-Watt e-bike is carrying
  • The quality and condition of the 1500-Watt e-bike’s battery
  • The mode of pedal assistance the rider is riding the 1500-Watt e-bike on
  • The way the rider rides their 1500-Watt e-bike
  • The quality and condition of the 1500-Watt e-bike’s tires
  • The external weather conditions

Continue reading to learn in great detail how each of the factors mentioned above will impact a 1500-Watt electric bike’s top and average speed.

Factors Affecting the Top and Average Speed of a 1500 Watts Electric Bike

The Total Weight the 1500-Watt Electric Bike is Carrying

A 1500-Watt electric bike is undoubtedly one of the strongest and bulkiest electric bikes on the market; however, it too has its limits.

If a rider is on the heavier side or is carrying hefty luggage on their electric bike, the e-bike’s performance will be affected.

The electric motor will have to do more work to convert the electric battery’s stored chemical energy to kinetic energy to allow the bike to reach its advertised top speeds.

Since a lot of the produced kinetic energy will be used to pull the weight of the rider and the luggage, the electric bike will not be able to reach its top speeds.

over, pushing the electric bike to go faster will only add damaging stress to the electric battery, causing it to permanently lose some of its charge storing capacity and lifespan.

The Quality and Condition of the 1500-Watt Electric Bike’s Battery

The battery of an electric bike is its most critical yet sensitive component. It is responsible for storing electric charge in the form of chemical energy. It is also what sends the required current to the eBike’s various components.

If the condition of the 1500-Watt electric bike’s battery is compromised, it will not be able to store the charge required for a long trip.

Without sufficient electric charge, the motor won’t be able to generate the power needed to propel the bike forward. This will result in lower top speeds and a compromised range.

The Selected Mode of Pedal Assistance

Nearly all 1500-Watt electric bikes come with four to five modes of pedal assistance.

If a rider travels to a far-off destination, they are recommended to stick to a low level of pedal assistance and pedal more to ensure that their battery lasts as long as possible.

If the rider rides on the highest mode of pedal assistance for most of the journey, the electric bike’s battery charge will drop quickly.

As a result, with less battery charge available, the bike won’t be able to produce the power required to reach its top speed.

Eventually, the electric bike will no longer be able to hit high speeds during the trip without a full recharge.

The Way the Rider Rides their 1500-Watt Electric Bike

The way a rider rides their 1500-Watt electric bike will have a significant impact on the e-bike’s average and top speed.

  • If the rider rides the e-bike at varying accelerations and frequently hits the throttle, the battery will deplete much faster.
  • As a result, less kinetic energy will be produced, and the e-bike’s average and top speed will go down.
  • As a result, the battery will deplete quickly, and the e-bike will not be able to go at high speeds.

The Quality and Condition of the 1500-Watt Electric Bike’s Tires

Riding a heavy 1500-Watt electric bike on old, worn-out, and sticky tires will add unhealthy stress to the electric bike’s battery.

As a result, the battery’s charge storing capacity, total lifespan, and range will permanently be compromised.

With less charge being stored, the electric bike will no longer be able to attain or maintain high speeds.

The External Weather Conditions

  • If a person is riding their electric bike against strong winds, more battery charge will be used to maintain momentum and speed.
  • As a result, the decreased battery charge will limit the e-bike’s ability to go at a higher speed.

  • Consequently, with less kinetic energy production, the e-bike will not be able to hit its advertised top speeds.

Final Thoughts

A 1500-Watt electric bike can be an incredible accessory for someone who enjoys a thrilling high-speed bike ride.

Although a 1500-Watt electric bike can go up to a top speed of 43 miles per hour, this is usually hard to achieve.

Factors like a rider’s body weight, road conditions, battery quality, wind speed and direction, and riding practices will have a massive impact on the electric bike’s actual speed.
