Best Electric Bike Kit – A Buyer’s Guide

If you love cycling but feel like you could use a little help every now and then, an electric bike kit could help you convert your traditional bike into an electric bike. Investing in an electric bike kit is also a more cost-effective solution compared to buying an electric bike.

This guide will show you what to consider before buying an electric bike kit and which are the most popular models on the market. If you don’t feel like reading, click on the links below to check out our selection.

An electric bike could be an adequate solution for many cyclists compared to the traditional bike, especially if used majorly for commuting. An e-bike is a regular bike fitted with an electric motor that only comes into operation during pedaling.

Moreover, the motor should also stop assisting the cyclist if a speed of 16 mph is exceeded. In other words, the motor only acts as an aid, also known as a PAS device, that assists cyclists and allows them to pedal with less effort.

What Is An Electric Bike Kit?

An electric bike kit, also known as a bike conversion kit, is a set of instruments and devices needed to transform a traditional bike into an electric bike. Usually, the kits should not have a motor with a power greater than 250W, although higher powers are available on the market, and the motors are usually powered by a rechargeable battery.

The main advantage of mounting an electric bike kit on your bike is the fact that you can still use your favorite bike for commuting or training, rather than changing it. Moreover, this method is also cheaper compared to buying a brand new electric bike.

On the market, there are dozens of models of electric bike kits available. Although they will ultimately do the same thing, they have different types and the costs also range widely between a few hundred bucks and a few thousand.

Naturally, the price is proportional to the quality of the components, including the motor, battery, the pedaling detection system, board computers and other elements usually included in the kit.

As a side note, we strongly recommend investing in an e-bike if you don’t have a bike at all. If you have to invest in both bike and electric bike kit, is simply not worth the hassle of installing the components yourself.

How To Install An Electric Bike Kit

How To Choose An Electric Bike Kit

Choosing an electric bike kit is not always simple and there are many things to check out before deciding which one is the best for you.

The first thing to consider is the compatibility with your bike. Some electric bike kits require free space on various points on the frame, such as for example on the center of the frame. Generally, manufacturers provide precise information on space and frame requirements, and if the kit doesn’t specify these details it’s probably not worth investing in it.

The minimum size of the bike should also be mentioned in the instruction manual. But despite size and space, you should also pay attention to the strength of the frame in particular and bike in general. An electric bike kit will add a few pounds of extra weight and you should make sure that your bike can support it.

Apart from these considerations, you should also make some general considerations that are similar to those you should make before buying a brand new e-bike.

One of the most important things to consider is the customer service offered by the manufacturer and also the existence of service points that you can contact for the kit’s maintenance and issues. Keep in mind that you’ll need to replace the battery every two or three years, or you might need assistance if the unit brakes down.

For this reason, it is recommended to choose a kit manufactured by a trusted brand. This is essential for what regards the spare parts but also the product’s warranty. In fact, an anonymous company which may import low-quality electric bike kits might close and leave you with a bad engine or no spare parts.

Regarding the installation of the kit, assembling and mounting an electric bike kit is not particularly complicated but it does require some familiarity with the mechanics of a bike. However, if the kit comes with clear and detailed instructions you might be able to mount the kit in your garage.

The simples electric bike kits comprise a motor that should be mounted on the front wheel. These kits are usually easy to mount and only require a bit of skill and patience. However, some kits have a motor that should be installed in the gravitational center of the bike, usually in the middle of the frame. These kits are harder to install and you’d better ask a professional mechanic for help.

Moreover, keep in mind that if the kit doesn’t fit properly on your bike, or if it is badly mounted, it may break in a short time, becoming useless. Additionally, most manufacturers recommend the mounting by trusted service providers and in some cases, you might even lose warranty if you mount the electric bike kit yourself.

The warranty of the bike might also be lost after the conversion.
