Are you torn between choosing a powerful kit and a road-legal kit?
Well, have both in one!

The UK/EU regulations dictate that a kit must not exceed the rated power of 250W to be road-legal. Which is not great news for the thrill-seekers, power hungry among us who want to have the occasional fun off-road yet still be able to ride sensibly and legally on-road. A purchase of the common high-powered kit will come with its legal implications. On the other hand, the practicality of a road-legal kit means giving up the fun one could have off-road. So which kit do you choose?

With these new rear wheel kits, CycloTricity had set out to resolve this very dilemma for its customers. We have developed a unique system that allows the user to swap between two modes depending on whether you are on-road or off-road, allowing you to unlock the full power where it is safe and legal to do so.
This dual-mode system is embedded in the LCD Dashboard which can unlock the full power of the kit using a special code (this can be obtained upon signing the de-restriction terms of use).
Please note that this is not the same as a de-restriction switch which has been questionable from a legal standpoint.

We’ve gone to extraordinary lengths to ensure you get the most out of your conversion kit purchase, with the most robust and durable components today’s technology has to offer. All at arguably the best value for money kits found in the UK.

1000W version reaches maximum speed of 50km/h once de-restricted (requires 48V battery)
Wheel size: 26inch, 700c, 28inch or 29er

Apart from a battery, the above is all that is needed to fully convert a bicycle into an electric bike. All our kit packages include these essential items. All you need to add is a battery (and the optional PAS upgrade if required).

Pedal Assist System Upgrades

Why not upgrade your conversion kit by adding one of our optional Pedal Assistance Systems (PAS)? A Pedal Assistance System is a device that senses your pedalling and makes your kit give automatic assistance, i.e. you do not have to press the throttle throughout your journey.

We have two PAS packages on offer:

Pedal Assistance System with LED Dashboard (Basic)
This is our basic PAS upgrade which includes a handlebar dashboard allowing you to shift between three power levels; low, medium or high.
Compatible with the 250W and 500W systems only.

Pedal Assistance System with LCD Dashboard (Advanced)
This is our top of the range electric bike kit upgrade for you who want to combine your conversion kit with state of the art technology, yet at a surprisingly good value. This package combines a Pedal Assistance System with an advanced LCD handlebar monitor which, not only gives you five levels of power, but also displays your speed, journey distance, time, average speed and many other readings.
Compatible with the 250W, 500W and 1000W systems (the LCD computer is required to unlock the full power of the 500W and 1000W systems for off-road use).
Although these are optional upgrades, you are highly recommended to install a Pedal Assistance System as it will transform your riding experience and improve the longevity of the battery. You can add one of these packages to your cart from the Prices tab.

IMPORTANT: If you wish to include a Pedal Assistance System with your eKit, the bottom bracket on your bike needs to be a Square Taper type (which is the most common bottom bracket on ordinary bikes). If you don’t have a square taper bottom bracket, you may need to replace it as well as the crank arms to make your bike compatible with the PAS. If in doubt, please consult a bike service shop on how to fit a square taper bottom bracket on your bike.
Alternatively, you may opt for purchasing the LCD Dashboard only without the PAS if you want the de-restriction functions but prefer not to fiddle with your bottom bracket.

Things to think about before purchasing this rear drive conversion kit:

- The rear drive motors are only compatible with a 3speed, 6speed, 7speed or 8speed freewheels (not compatible with a cassette type gear). If you have a single speed bike, you can install a 3speed freewheel for compatibility (and use only one of the 3 speeds).

- The rear forks on your bike need to have 135mm clearance between the drop-outs (which is the case with the vast majority of bikes)

- The LCD computer is necessary to unlock the full power of these high power motors. Can be purchased at a later stage if full power is not immediately needed.

- The electric brake levers supplied with the kits are mechanical. I.e. they are not compatible with hydraulic brakes or brakes that are combined with gear levers. However, installing the brake levers are not a necessity and the kit will work fine without them. Moreover, the throttle is spring-loaded, i.e. it will cut the power whenever the thumb is released from it for safety.
