250W/500W Mid-Drive eKit
The Cyclotricity 250W/500W motor kit offers a good 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.
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.
The Cyclotricity kits can be fitted to standard bike frames through a simple installation process, detailed in our video guide.
- Mid Drive Brushless Motor (with integrated controller). Restricted to 250W by default as a road legal kit. 500W mode reaches maximum speed of 32km/h once de-restricted (requires a signed disclaimer to derestrict for off-road use).
- LCD Display
- 42 Tooth Chain Wheel + Plastic Chain Cover.
- 2 x Brake Levers.
- Left And Right Crank Arms.
- Speed Sensor + Magnet.
- Waterproof Quick Release Cables.
Apart from a battery, the above is all that is needed to fully convert a bicycle into an electric bike. All you need to add is a battery (and the optional Throttle upgrade if required).
Things to think about before purchasing this mid drive conversion kit:
- 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 depending on your bike configuration. Your local bike shop can help you with chain adjustments.
- You can only use this as a 1 ring set up. I.e. if you have 3 front gears, these will becom one. With an electric motor installed, you won't need the front gears.

The most cost effective strategy in a kit purchase is working out in advance what you’ll generally use it for. That way, you can pick a configuration suitable for your needs without adding unnecessary costs. Front and rear drive kits both have their own unique characteristics. We have divided our kits into four categories that generally cover the needs of most people. To help you narrow down what’s right for you, here is a summary of the main differences:
250W Front Drive
The front drive kit is a geared hub motor which means it is a lot smaller and lighter than its rear drive counterparts, in fact, it is barely noticeable as a motor once installed. In other words, if a lightweight and well disguised kit is of importance, this is a good option to consider. Combined with pedalling, it gives an all-wheel-drive experience offering better stability and weight distribution with the battery. It is also a lot simpler to install than a rear drive as there is no need to readjust any gears.
Even though 250W is less power than the other categories, remember that 250W is the maximum power legally allowed on-road, so it is a perfectly adequate hill climber with equivalent power to the majority of purpose-built electric bikes on the market.
The front drive kit is also the most cost effective, in other words, if you intend to use the kit on-road most of the time and spend as little as possible, this would be the pragmatic choice.
500W Rear Drive
We’ve introduced this category as it uses the same 36V batteries as the front drive motors. Which makes this kit strike the perfect balance between cost and power. Prices are not much higher than the 250W front drive but with the benefit that once you add the LCD computer, you can de-restrict it (for off road only) and get a glimpse of some of the power that you can experience with the high power off-road kits. In other words, it is the best of both worlds at great value. The only downside is it’s heavier than the 250W front drive kit.
This kit is recommended for you who are on a budget, does most of cycling on-road, but want the occasional off-road fun added and don’t mind a slightly heavier bike. Please note that the kit will be supplied restricted to 250W by default and will require the LCD add-on to de-restrict it to the full 500W for off-road use.
1000W Rear Drive
This category is our favorite! Once you try it, you can never go back to anything else! It has been developed purely for the thrill seekers among us. Since it’s a 48V system, the battery makes it more costly than its counterparts. Having said that, it offers an adrenaline-fuelled ride rarely found in conversion kits. It is packed with torque, power and will propel you to speeds up to 50km/h and climb incredibly steep hills. This kit is recommended for the outdoorsy spirit, the mountain biker and you who appreciate the exhilaration that comes with speed and power. Please note that the kit will be supplied restricted to 250W by default and will require the LCD add-on to de-restrict it to the full 1000W for off-road use.
500W Middle Drive
This category is the all-rounder. It is as light as the 250W Front Drive, but with the power of a 500W motor! In fact, it has torque much higher than the regular 500W Rear Drive kit, which makes it a much better hill climber. It is positioned in the middle of the bike for the best weight distribution there is. It uses a 36V volt battery which makes it a fairly cost-effective purchase. The PAS and LCD screen are included by default making for an extra cost saving.
It is also suitable for non-standard bikes that has unusual forks where hub motors don’t fit.
