The 6 Best E-Bike Conversion Kits of

Final Verdict

Whenever you’re buying a newer technology, sticking with a known brand makes sense. That makes Bafang’s E-bike conversion kits (view at Amazon) a sound choice—in terms of quality and price. If speed is what you’re after, the kits from Ebikeling (view at Ebikeling).

What to Consider When Shopping for an E-Bike Conversion Kit

Battery

Is the battery included? You’ll need something to power and charge your e-bike conversion kit. Many kits include a battery. Cheaper kits may not, though, which means you’ll need to source a compatible battery separately.

Power

You'll also want to think about your power needs. The higher the motor wattage, the more power you'll get. A watt motor is typically plenty of power to make the daily commute less sweaty. If you want to take your converted bike out on tougher mountain trails, you'll want more power.

Keep in mind that according to U.S. federal regulations, e-bikes with more than watts of power are considered motor vehicles and require a motorcycle license.

Local Laws

You’ll want to check your state and local laws as some cities and towns have banned e-bikes from bicycle paths, so if that’s where you want to ride, you’ll want to make sure your town allows your upgraded bike to cruise around on them.

E-bikes come in three classes:

  1. Class 1 E-bikes that assist you while you pedal and top out about 20 mph.
  2. Class 2 E-bikes have a throttle that assists you regardless of whether you pedal and have a top speed of 20 mph.
  3. Class 3 E-bikes assist you while you pedal and top out about 28 mph.

FAQs

Are electric bike conversion kits difficult to install?

There are several kinds of e-bike conversion kits, and the ease of set-up and installation varies.

  • Friction Drive Conversion is a simple strategy. A roller pushes against the tire on the wheel. When the roller turns, the wheel turns. It’s a reasonably easy system to set up but often isn’t the most effective.
  • Mid-Drive Conversionis the technology that the best e-bikes tend to use. A weight sits at a low point on the bike frame, and the power is applied to the crank. These can be more expensive, but the technology is typically better. There’s no standardization, however, which can make figuring out exactly what you need to make your bike work a little more challenging. Adding the parts is also a bit more complex than friction drive conversion.
  • Electric Bike Wheel Conversion swaps out a non-electrified front or rear wheel with an electrified one. The process is simple depending on where and how the battery mounts—such as on a rear rack. Once installed, weight distribution can feel natural. However, powering the front wheel may impact your bike’s handling.

What tools do I need?

You’ll need a bike tool, crank arm tool, adjustable wrenches, and a screwdriver along with your electric bike conversion kit.

These demos can show you how to install your e-bike conversion kit.

Should I get a conversion kit or just buy a new e-bike?

A visit to your local bike shop mechanic is a helpful step in the decision-making process. They can help you determine if your bike is a good candidate for electric technology.

Your old bike may not be able to be converted because adding a motor can increase torque. You’ll want to make sure your bike’s drivetrain can handle it.

The extra weight from adding an electric motor also impacts your brakes, so you’ll want to make sure they are effective for stopping at a higher speed. E-bikes tend to have disk brakes for this reason. If your current bike is in disrepair, has old parts, or needs other improvements, it may be more cost-effective to sell your trusty old ten speed and buy an e-bike.

Also, consider that a quality electric bike conversion kit can be nearly the cost of an electric bike. Do some comparison shopping between the price of a conversion kit and a fully-loaded e-bike before you decide which way you want to roll. Our picks for the best e-bikes may help guide your decision.

    I have about 680 miles on this motor so far... However, I said "motor" not the "kit". The rubber rag joint (old tire material) for the rear sprocket is terrible, and is easily the worst part of this kit. Get a hub adapter, and a 40t sprocket. The chain tensioner is also dangerous. The spring loaded chain tensioner is much better. Also, plan on buying a better 415h chain.

    Best electric bike conversion kits: Give your current bike a power boost

    If you don't want to buy an e-bike outright, the best electric bike conversion kits allow you to transform the bike you already have into something that gives you the boost you're after.

    Electric bikes have come into the global conversation in a big way. They are suddenly everywhere and everyone wants one. It's not a fluke and there are lots of benefits to having one: they make the world more accessible without jumping in a car, and they still provide a great workout. Whether you're looking for the best electric bike for commuting or want to hit the trails after work with the best electric gravel bike, the right e-bike lets you tackle longer days, steeper hills, and heavier loads. 

    The only thing that might be stopping you is the price of one. A way around that is to convert a bike you've already got sitting around. Waste not, want not, right? You've already got a bike you love, so why spend money on a brand new bike when, with the right knowledge and the right kit, you could take that old bike and add electric assist for less money and less hassle. 

    Continue reading to see our suggestions for the best electric bike conversion kits, or jump down to the bottom and see some of the things to think about as you shop.

    Best electric bike conversion kits

    Bafang Mid-Drive Motor Kit and Battery

    A mid-drive all-inclusive kit from one of the best-known brands in the industry

    Wattage: | Battery included: Yes | Motor position: Crank

    US support

    Lots of options

     Needs better directions 

    Bafang is one of the largest and most well-known electric bike motor companies in the world. It's been around since and in Bafang established a US arm to better support the US market. There are many well-known electric bike companies sourcing its components, so if you want to get in the game and source your own electric bike components, you won't go wrong with Bafang.

    This particular option covers everything you need for a mid-drive motor conversion kit. As long as the bike you are starting with has a bottom bracket sized between 68 and 73mm, this kit will work. From there you can choose the front chainring size, the battery size, and what display works for you.

    Bafang Front Hub Motor kit and Battery

    Stick with a well-known brand but opt for the ease of setup that comes with a front wheel motor

    Wattage: | Battery included: Yes | Motor position: Front wheel

    US support

    Lots of Options

    Easy Install

     Power delivery is abrupt

    If you like the idea of converting your bike to electric-assist but you can't, or don't want to, make use of a mid-drive setup, then the Bafang Front Hub kit makes things much easier. 

    Like the mid-drive system listed above, the Front Hub Kit covers everything you need and gives tons of choice. Start by choosing your wheel size and display preference, then add the battery size and shape you'd like. 

    With all the options available, finding the kit to fit your bike is easy.

    Alizeti C E-bike System

    As easy as installing a rear rack

    Wattage: | Battery included: No | Motor position: Rear Tire

    Lots of extra features

    Easy to Install

    Light

    Expensive when you include the cost of the batteries 

    Friction drive electric bike conversions are not the most efficient option. What they lack in efficiency though they make up for in ease of installation. As long as you've got a place to bolt on a rear rack the Alizeti C is dead simple to install and that extra secure fit makes for a better experience. Pushing against the rear tire requires a solid mounting system and Alizeti has it. Beyond electrifying the ride there's also a collection of other features. A speaker and a lock add security when parked and when the speaker isn't in use as an alarm you can play music through it.  

    Swytch Universal Kit

    A clever and attractive kit that is easy to install on almost any bike

    Wattage: | Battery included: Yes | Motor position: wheel

    Shows battery power and assistance mode

    The hub is available without a wheel for something unique

    Easy to take the battery pack with you and avoid theft

     Cadence sensor can be hard to fit 

    Swapping the front wheel is one of the easiest ways to convert any bike to an electric bike. That's the approach that Swytch takes but a good system is more than just a motor and battery. The Swytch kit thinks through the whole system. The battery mounts to the handlebars and it's easy to take with you so it doesn't get stolen. While riding there are lights on the top of the battery pack to show how much battery you've got and what assist mode you are in. There's also a cadence sensor that attaches to your bike. It's a well thought out system and it looks great. 

    Tongsheng Mid-Drive Kit with Battery

    A torque sensor-based pedal assist with a mid-drive motor is the gold standard for natural feeling acceleration

    Wattage: | Battery included: Yes | Motor position: Crank

    Torque sensor-based pedal assist

    Natural feeling acceleration

     Instructions aren’t great

    The most natural-feeling motor is going to be a mid-mounted motor. If that works for you and you also like the idea of doing some pedalling, then the very best is a mid-mounted motor paired with a torque sensor. 

    Instead of the system knowing you are pedalling and adding power, a torque-based system adds a percentage of power. Max torque available on this system is 80Nm but depending on your chosen assist level, that 80Nm will add between 36 and per cent to your pedalling power. 

    To keep it simple, think about it as an amplifier. If you pedal harder you go faster, just like a normal bike, but now your muscles have extra support. 

    Rubbee X Base Model

    The absolute simplest install possible

    Wattage: w | Battery Included: Yes | Battery Position: Rear tire

    Regenerative Braking

    Completely wireless

     Mounting lacks bracing

    There are a number of simple install options on the list but the Rubbee X takes it a step farther. Attach a mount to the seat tube and click the unit into the mount. There's also a cadence sensor but that's wireless too. There's nothing easier than that and you get a slick looking watt motor with a single battery in the base kit. If the mile range of the base unit feels a little constricting add another battery and double the range. If you need to change assistance modes grab your phone and open up the app.  

    Pendix eDrivestart

    The advantages of a torque sensing mid-drive kit with a dealer network for installation and support

    Wattage: w | Battery Included: Yes | Motor Location: Crank

    Fits most bikes with a threaded bottom bracket

    Torque sensing pedal assist

    Dealer Installed

    Expensive

    If you like the idea of a mid-drive system and you want it to have torque-sensing pedal assist then you've got a couple of choices. The challenge with a system like that is complexity. For some people it's no big deal to take apart a bottom bracket but for others it's intimidating. The Pendix system does the same thing as other kits but it has a dealer network that handles sales, support, and install. The model that Pendix uses means you can feel comfortable that the system is correctly installed and your bike is ready for it. 

    1. Make Sure You Get a Battery

    There's not a huge explanation needed for this. You need a battery; make sure the kit you select has it. Not all kits include it. If you find yourself browsing through options and landing on something with an unbelievable price look for the battery. You can source the battery yourself but be sure about what you are getting.

    2. Types of Conversion Kits 

    Friction Drive Conversion: A roller pushes against the tire on the wheel and when the roller turns the wheel turns. This strategy isn't all that efficient but it's simple. There's very little challenge with making it work but at the end of the day it doesn't work all that well. 

    Mid-Drive Conversion: The best electric bikes tend to be mid-drive and the same is true of conversion kits. The weight sits low in the frame and the power gets applied to the crank for a more natural sensation. The only downside is pricing and packaging. Different standards make it challenging to figure out exactly what you need and there's more work involved in adding the parts. 

    Electric Bike Wheel Conversion: Swapping either a front or rear wheel for an electrified version is a good balance. The conversion process is very simple and depending on how the battery mounts the weight distribution can be quite good. Powering the wheel does change the way the power delivery feels and making the front wheel heavy can affect the handling of the bike. If mid-drive seems overwhelming this is an excellent option. 

    3. Consider Unknown Brands

    In the world of electric bikes there are a lot of brands you may not have ever heard of. There is a boom going on so new brands are popping up all the time. Not only that but Europe, and especially the US, are playing catch up to the trend of electric bikes. You will probably stumble across a lot of unfamiliar brand names. 

    Consumers have a tendency to look away when they encounter a new brand. It's not a bad strategy but in the electric bike world, including conversion kits, you've got to be more open than that. If you aren't open to names you've never heard of you will find the options limited. A lot of the names you may come across are unfamiliar to you but have a solid history behind them.

    That doesn't mean you should go forward blindly. Do your research and be careful with your money like always. The only thing that might be different is a need for being open to new companies. At the very least be willing to look a little deeper.  The brand you've never heard might actually be a well-established brand from a different part of the world. 

    4. Should you buy an electric bike instead?

    Remember to consider all your options. You have a bike in the shed you haven't touched for a lot of years. It seems like a perfect candidate for conversion to an electric bike. It might be but it's also just as possible it's a better candidate for a sale. Sometimes it's better to take the money and fund an electric bike someone else built. 

    As with anything, consideration for the end use during design and build can have advantages. A quality electric bike conversion kit might end up being very close to the price of a complete electric bike. If a company starts with a clean slate and designs an electric bike it's easier to keep costs low and integration high. Really consider why you are thinking about converting your bike and does it make sense compared to what's on the market. In some cases it will but in others, it won't.

    Consider the condition and componentry of your old bike as well. With an electric motor dramatically increasing the torque, using a low quality or worn drivetrain will result in poor performance with shifting being affected and the chain skipping or even snapping. Another important consideration is the brakes, adding the extra weight and increasing potential speeds put more stress on the brakes as they try to curtail momentum. We recommend choosing to convert a bike that has disk brakes as they will provide far better braking performance.

    5. Don’t Forget Local Laws

    Whatever kit you end up deciding on make sure you have an understanding of the local laws that govern electric bikes. Given the connected nature of our global economy, it's possible to buy kits you can't use where you want to. It's also important to understand how you can use the new electric bike you have. Depending on the kit, and its power, you may not be welcome on bike-only infrastructure. Make sure you understand what you are buying and consider how and where you want to use it.  

    Individuals carrying out the instructions in this guide do so at their own risk and must exercise their independent judgement. There is a risk to safety if the operation described in the instructions is not carried out with the appropriate equipment, skill and diligence and therefore you may wish to consult a bike mechanic.
