Need more power for your bike? Before shopping for a brand new e-bike, consider getting a conversion kit instead and you’d be amazed at what your old but modified bike can do. 

What is an electronic bike conversion kit?

Essentially, an Electronic Bike Conversion Kit (or e-bike kit) is a device that allows you to convert your existing regular bicycle into an e-bike. The conversion kit uses the power of electricity and battery cells to provide assistance when pedalling, allowing for easier riding on hilly terrain or in traffic. It also helps reduce fatigue by providing continuous support, especially during long rides.

How does it work?

The e-bike conversion kit converts your regular bicycle into an e-bike using two different types of batteries: lead-acid and lithium-ion. Both are rechargeable so there’s no need to worry about replacing them once they run out of juice. When you pedal, the motor turns the rear wheel via the chain drive mechanism. You will feel this difference immediately because the motor provides extra torque which makes cycling much more comfortable than just peddling alone.

What we have here is a list of the best e-bike conversion kits in the market today. These kits are rated according to their power, ease of installation, and overall functionalities. While browsing this list, you will find that some e-bike conversion kits have a lower power output but reach the same speeds as a bike that’s modified with a higher-spec kit — this is natural as speeds can vary depending on weather conditions, inclines, and terrain condition.

Bafang Brushless Hub Motor Rear Wheel / 7 Speed Freewheel Ebike Conversion Kit with Battery (48V 500W 750W)

The second BAFANG on our list is a rear-wheel e-bike conversion kit that promises extra power and riding comfort to commuting bikes, touring bikes, mountain bikes, and the likes. With a rated power of 500W, it can help you reach speeds of up to 24-25 mph at 470 RPM! One of the awesome things about this BAFANG rear wheel conversion motor is that it allows the rider to switch between two riding modes so you can still use your bike for exercising.

This model is available with different types of LCDs and batteries are shipped separately from the motor so you might have to wait a bit before you can start working on converting your bike. The reviews are mostly favorable though largely thanks to the excellent after-sales service. Although the manufacturer promises easy conversion that would take an hour max, be ready to use your mechanical skills as some bikes would require you to make modifications to attach the kit.
