Due to the cost of running the Cycle To Work Schemes we have to add a 10% fee on top of the kit price to maintain profitability, otherwise we cannot afford to be apart of the scheme. Sorry for the inconvenience.

Let's help fit your kit

Electric bike conversion kits are still quite new to the UK and inevitably you'll have questions about how to fit your kit. The good news is that you can contact us to ask us, either by calling us, using the live chat or sending us an email via the website.

We'll always offer straightforward and clear advice and, because we have fitted conversion kits hundreds of different bikes, we know exactly what we're talking about.

It's all very well selling conversion kits but unless you've fitted one from the ground up then you don't necessarily know what makes a quality kit fit - our experience in building electric bikes gives us a unique insight and therefore we can offer to fit your kit for you!

This is our best selling kit and our favourite as well! This 250W/500W motor kit offers a great combination of strong torque, high efficiency with low power consumption and noise output. The mid drive motor transfers power through the bikes gears, meaning the motor can operate within its optimum RPM range which is ideal for hill climbing. Paired with the larger batteries, this kit is one of the best out there! 

The unique 250/500W system allows you to have a higher power option where it is safe and legal to do so while still maintaining the ability to use the low power option on the road for maximum efficiency. When in 500W mode, this kit can reach speeds of up to 25 - 30mph. 

To fit this kit there are a few things we would need to check:
- The bottom bracket of your bike will need to be between 68-73mm wide in order to work with this mid drive, you will also need to consider space for the motor.
- The chain ring is 42 tooth so chainline will need to be fairly standard and the chain may need to be lengthened or shortened, also you can only use this as a 1 ring set up.
