Class 2 ebike kit

Last Updated on July 25, 2022

I’m a huge advocate for biking as a form of commuting to work and running errands. After all, I sold my car and bought a bike after my move to Maine!

Biking is great exercise and a way to lower your carbon footprint. However, it’s not always the most accessible option – and that needs to change if we want to create more walkable, less car-reliant cities.

Functional and accessible bike lanes need to become the norm in many cities for this to happen. For example, in NYC BIPOC neighborhoods tend to have the most lack of cycling infrastructure, community engagement around streets, NYPD involvement in bike safety, and access to bike shops and services.

With that said, if you do have access to safe biking lanes, or don’t own a car like me, it may be worth looking into e-bike conversion kits. E-bikes are bicycles equipped with an electric motor to assist you when you’re pedaling. This really comes in handy when you’re carrying a heavy load up a steep hill!

The motor is powered from a rechargeable battery mounted on the bike. How much power your motor delivers will depend on how hard you’re pedaling and the type of e-bike you’ve acquired.

Interested but don’t know where to start? Here are the best e-bike conversion kits available on the market!

what is the best type of ebike conversion kit?

The best type of e-bike conversion kit will depend on your specific needs and wants. That being said, there are three types of e-bike conversion kits available you should know about.

The best electric bike conversion kit is typically a mid-drive conversion kit because it has the most power and is typically the highest quality.

E-bike conversion kit types:

  • Mid-Drive Conversion Kit: These kits comes with a motor that sits between the pedals in the middle of your bike. Mid-drives tend to be smaller and lightweight, yet offer greater torque. The weight balance is optimum. Best for off-roading or use as a mountain bike. They tend to be expensive.
  • Hub-Drive or Wheel Conversion Kit: Electric motor is typically connected to the front of rear wheel. Weight is slightly off balance due to bulkier motors. Affordable and versatile. Perfect for daily commutes. Cheaper and easier to install.
  • Friction Drive Conversion Kit: Kit comes with a roller attached to the motor. When the motor is activated, it powers the roller that moves the rear wheel using friction. Noisy and not always the most balanced. Tends to be the cheapest option and easiest to install.

It’s also worth noting e-bikes can range in power from 250 watts to over 750 watts. Typically, they add between 12 to 25 pounds to the total weight of your bike.

Personally, I recommend finding e-bike conversion kits with battery, as this will save you time and money. Otherwise, you’d have to purchase the battery separately and this can get rather costly.

To electrify your bike, altogether you need a battery, sensors, controls, and a motorized wheel or a drive unit. The best e-bike conversion kit will have all these features.

are ebike conversion kits worth it?

E bike conversion kits are worth the money if you plan to make use of them frequently. If you use it in place of a car, it will eventually pay for itself (think of all the gas you’d save). Kits are also generally cheaper than buying a whole new e-bike.

Conversion kits are generally easy to install if you have the right tools. Even new e-bikes often require some assembly.

Conversion kits are also better for the environment than buying a whole new e-bike because you get to use the bicycle you already have.

Also, e-bikes will make going up hills and running errands so much easier due to the additional assistance they offer. An electric bike will usually have between three and five levels of assistance. You can select this via its controller. These can give you anything from a gentle push to lots of power.

Some may even have a ‘boost’ button, which you can use to increase the power output for short bursts of additional power.

Generally speaking, if you’re looking for more power from your e-bike kit, look for the wattage rating. Comparatively, a 750W motor will pack more of a punch than a 400W motor.

Also, be aware that the time duration your e-bike can sustain the rated power output may only be for a brief time. Don’t expect full power the whole trip!

Please be advised there are three classes of e-bikes, and they come with specific speed limits in the US:

  • Class-I: E-bikes with only pedal assist and max speed of 20mph.
  • Class-II: E-bikes with pedal and throttle assist and max speed of 20mph.
  • Class-III: E-bikes with pedal assist (with or without throttle assist) and max speed of 28mph.

can you turn any bike into an ebike?

Yes, you can turn any regular bike into an e-bike. However, you will need to consider whether the bike can handle a motor, especially if you want a powerful one. You’ll also want to double check the kit is compatible with your bike’s size.

Most e-bike conversion kits involve replacing the wheels. Here are the basic steps to know:

  • Remove the existing wheel and replace it with a motorized wheel (assuming your conversion kit comes with one). You’ll have to loosen the rear brake and wheel quick release level using a bike tool kit.
  • Attach the tire, tube and freewheel to new wheel. Your bike tool kit should contain some tire levers you can use to do this. Some e-bike kits come with a new freewheel, and if that’s the case, use the new one.
  • Mount the motorized wheel to the bike by securely tightening the nuts and installing the torque-arm set. Follow manual instructions.
  • Run the motor cable to the battery to the handlebars and secure them with zip-ties.
  • Install the display and controls, but first remove any existing grips, gear shifters and breaks from the handlebars. Then mount the throttle, brakes and brake wires, speed shifter, cruise control and pedal-assist sensor any place you prefer. Based on your e-bike conversion kit, the types of control units will vary.
  • Install the battery – if it comes with one. If not, make sure the battery you get matches the motor specifications.

how much does an ebike kit cost?

An e-bike kit can cost between 300 to 700, depending on the type you get. Mid-Drive conversion kits tend to be the most expensive and can even go beyond 700 in some instances. Friction Drive conversion kits tend to be cheaper, but their performance isn’t always as efficient.

how long do ebike batteries last?

E-bike batteries can last between 3 to 5 years if it’s well maintained. Just be aware if it’s a lithium battery, it will slowly lose its capacity over time, even when not in use.

Here are some tips to keep battery life optimal for as long as possible:

  • Keep the battery cool
  • Store a battery partially charged, but not too low
  • If storing the battery for a long period, ensure it has a charge between 80% and 40% of a full charge
  • Don’t frequently discharge your battery
  • For winter, make sure battery is above freezing before charging

how do I choose an ebike conversion kit?

You can choose an e-bike conversion kit based on your personal preferences, budget, and needs. The e-bike conversion kits I’ve listed in this article are some of the best on the market.

If you live in the US, make sure to double check if e-bikes are legal in your state, and the laws regarding them, before purchasing a conversion kit. For example, class 3 e-bikes are allowed only in NYC, not the rest of New York.

I’ve gone ahead and highlighted some key features of each brand, but it isn’t an exhaustive list. Be sure to check out their websites for more information.

The Mid Drive Ebike Kit You Should Never Buy (and the 3 Best)

E-bike kits, which generally refer to the mid-drive ebike kit and the hub-drive e-bike kit, have come a long way since the days of Michael Kutter who created a throttle-less E-bike controlled by pedaling in the early 1990s.

These days, the E-bike conversation has evolved into debates about the mid-drive E-bike kit vs the hub-drive E-bike kit, and which of the string of E-bike options available today has the best features and the most power.

But, which mid-drive e-bike kit is the best? And, is there one you should never buy?

This review outlines three of the best mid drive ebike kits and offers insight into costly, low-performance ones you should avoid.

What Are the Most Important Things To Consider When Buying an E-Bike Conversion Kit?

Compatibility with the non-electric bike, whether a front hub, rear hub, or mid-drive motor will work best and what the desired power output is.

What Exactly Is an E-Bike?

E-bikes have battery-powered motors that provide pedal assistance.

What Kind of Maintenance Is Necessary for an E-Bike?

What Is A Class 2 Electric Bike? We Explain Ebike Class Differences

There are three class types of electric bikes. We break down their differences, discuss which class are Rad Power Bikes, and why it matters.

Why Are There Different Ebike Classes?

Similar to motorcycles, electric bikes are classified into different categories based on their basic functionality. Let’s review the three ebike class types, based on a model ebike law that most U.S. states have adopted as the basis of their state regulatory system:

  • Class 1: Pedal-assist only; motor provides assistance all the way up to 20 mph.
  • Class 2: Pedal-assist or throttle; motor provides assistance all the way up to 20 mph.
  • Class 3: Pedal assist only; motor provides assistance all the way up to 28 mph.

Can ebikes go even faster? Technically, yes. However, Class 1 and 2 motors shut off at 20 mph, and Class 3 motors shut off at 28 mph. Any additional speed is gained by rider power alone, and/or decreasing elevation (riding downhill).

What Class Are Rad Power Bikes Ebikes?

Rad Power Bikes designs Class 2 ebikes. In fact, beginning in 2007, the company was one of the first to pioneer the combination of a throttle and pedal assist. When designing a safe, reliable, and enjoyable transportation solution, Rad took into account multiple factors: federal and local laws, bike usage, technology, and rider experience. The result: Class 2 ebikes with a full 750 watts of power.

Can Ebike Riding Be Illegal?

According to Chief Product Officer Redwood Stephens, the decision to design Class 2 isn’t a light one, and plays a factor into every bike Rad develops. First, Rad creates ebikes to be compliant under the CPSC (Consumer Product Safety Commission) regulations for safety requirements applicable to ebikes. Those regulations prescribe limits for motor power and the maximum speed that a bike can operate when powered solely by the motor.

Second, Rad Power Bikes are designed so our riders are comfortable that their ride is legal on most roads and bike paths, based on state laws. “We design our bikes to be safe, and compliant with the law,” confirms Stephens. In multiple states, ebikes with motors that provide assistance at or above 20 mph are not permitted on many types of bike-focused infrastructure. Riding beyond those state and local restrictions can go against traffic laws and regulations, and potentially require licensing and registration fees.

As a rider, it’s vital you check your local laws in the rare case a road or path is not yet following the model ebike laws that treat Class 2 ebike the same as a traditional bike. After all, what good is your bike if you can’t ride it?

About That Need for Speed

As Class 2 ebikes, Rad Power Bikes are engineered to not only perform well up to the 20 mph (the speed that the bike’s motor shuts off), but also accommodate additional speed that occurs when traveling downhill. However, some ebike brands are focusing on Class 3.

“To consistently travel safely at higher speeds, the bike frame, brakes, suspension systems, and more have to be engineered for that,” says Stephens. We asked Stephens if that was being done in the industry. “Not always. Higher speeds often requires engineering new parts from scratch,” explains Stephens, “but some brands are not upgrading critical systems that such speeds require.”

Safety and Technology

For Rad, our choice to FOCUS on building the best Class 2 ebikes comes down to providing ebikes that not only travel at safe speeds, but meet and beat rider expectations each and every day. Safety is paramount to ensuring bike trails and paths are accessible for everyone. Designing within Class 2 standards ensures that we are meeting that endeavor. It also ensures that when electric biking with your kids, passengers, or just for fitness and fun, a Class 2 ebike is designed to meet those needs.

At a Class 2 designation, Rad engineers strike that perfect balance between cost, quality, and safety. ensuring you get a safe ebike using quality parts; legal to ride in most places; and at a great price.
