5 Best Electric Bike Kits in 2021

Last updated 04. January 2021

E-bikes have been around ever since the early 2000s, but their popularity has exploded among cyclists of all skill levels in recent years. Electric bike conversion kits are more popular than ever and choosing one that suits your needs the best can be difficult if you aren’t familiar with the technical side of what they offer. Not all kits will give you the same parts and features, especially if they’re meant for specific types of bike, so it’s a good idea to research your options and buy an electric bike kit that fits your needs.

Below is our electric bike kit Buyers Guide of five high-quality conversion kits for creating an e-bike, as well as some of our reasons for recommending them and the types of cyclist that might need them most.

Electric Bike Kit Buyers Guide


Not every kit will work with every bike, and an incompatible kit will be more or less worthless to you unless you can afford a new bike to go with it. It’s key that you make sure you’re buying something that you can use: not only will certain bike chassis and models not work with certain electric bike kits, but they might also need specific wheel sizes or frame parts to fit properly.

You should also think about the kits themselves – will they work properly with other modifications or custom parts on your bike? A lot of professionals and hobbyists will have changed at least one part of their bike in a way that doesn’t match the factory models, and a permanent modification or upgrade could stop you from using an otherwise-compatible e-bike kit.

Accessibility and Safety

Certain electric bike kits will be accessible to new cyclists, or those who use their bikes for travel rather than recreation, but others might expect you to be familiar with e-biking and high-level cycling techniques right off the bat. You might also need to know certain skills to actually install them or connect specific parts together, especially if the manufacturer doesn’t provide any instructions or manuals with the kit.

Installing an electric bike kit incorrectly could make your bike far less safe to use, especially if you’ve replaced important parts. Keeping your purchase within your skill level is the best way to keep yourself safe while you’re using your newly-converted bike.

Extra Features

Some electric bike kits will come with extra features that you’ll never really use, but the way that most conversion kits work mean that you might have to install them anyway. This can make it harder to use your bike for day-to-day travel, mainly if you’ve had to add accessories that slow you down or stop you from controlling your bike manually. You might also end up paying an inflated price for features that you don’t want, and certain things (like speed control systems) could make up a significant part of the cost, even if you’ll leave them untouched and forget they exist.

Buyers Guide Questions:

Should my conversion be permanent?

Most kits won’t make a permanent change to your bike, but it can often be difficult to remove the extra parts on short notice: some will completely replace a bike’s front or back wheel, so you can’t switch back unless you still have the original wheel nearby, and others might use a special chain or pedal system that don’t function properly on a regular bike.

If you aren’t confident in your ability to take apart and reassemble your bike, you should choose your kit carefully, since it might end up being semi-permanent until your skills improve.

Should I try to modify the kit?

A lot of e-bike kits are supposed to work with specific types of bike, but they can still be modified to support others. First-time buyers should avoid doing this unless they’re definitely sure they can pull off such a tricky modification, and instead stick to buying electric bike kits that are purpose-built for the model or style of bike they prefer to use. In general, this kind of project is only recommended to professionals who want to use their mechanical skills to create a completely unique electric bike.
