The Cycle to Work Scheme is a Government-backed initiative to encourage people to cycle to their place of work, and consequently reduce environmental pollution. It's also a way for you to save money on the cost of your cycle and spread the cost over a number of months, through your pay packet.

How do I get a conversion kit through Cycle to Work?

The paperwork required differs for each scheme and should be available from your employer or from the links below for each scheme:

Cycle Solutions

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 the kit for those who are after an off-road focused high powered conversion kit. This mid-drive kits provide powerful ebike performance while maintaining the original pedaling enjoyment.

These motors are regarded as the very best in the EBike world. Extremely quiet and robust. Fully waterproof and internally lubricated within sealed casings.


All you have to do is select through to the options below we will pair up the correct batteries to each motor system. With your chosen specs we take care of all the important parts and we build the perfect kit, tailored for you. 

More torque than any other

Whilst there are higher-powered hub drive units available, nothing beats the hill climbing, wheelie-popping direct power of the mid drive. To tame the torque this kit includes the patented ‘Gear Sensor’ from Agentura REPRO by default. With other BBS units this is optional however because of the high torque of the BBS-HD, this is mandatory otherwise your transmission will be toast after 1 ride. The Gear Sensor system is easy to install and momentarily inhibits the power from the motor for just long enough to gear shift. You will need to select from 2 options (derailleur or internally geared hub) when purchasing.
GearSensor is the undisputed authority on design and development of this device which solves a common issue that all mid-drive electric bike drive systems are prone to. Agentura Repro has developed a GearSensor for derailleur and internally geared transmissions (select which below) that senses shifting and sends a signal to the BBS drive that inhibits the power for the perfect amount of time required for a complete shift. The GearSensor works reliably on every shift so you don’t have to think about coming off the throttle or ‘blipping’ the e-brakes.

Battery Options: 

  • 48v 13aH Frame Battery   -  Approx 25 miles per charge
  • 48v 17aH Frame Battery   -  Approx 35 miles per charge
