Equip your own bike with power assistance!
Wouldn’t it be great to keep cycling your ordinary bike yet never have to struggle with hills again? Or carry on your normal commute without having to arrive at work covered in sweat?
Now, you can! This electric bike kit (eKit) allows you to transform your bike into an e-bike for a fraction of the cost. Cycling will suddenly have a whole new dimension to it!
With a Lithium-Ion battery included, this is most probably the best value for money conversion kit you can find on the market.
The kit is a front motor-wheel design, making it incredibly simple to install. It usually takes less than an hour to complete the installation. But if you are not the DIY type, you can always seek assistance from a bike service shop. A full installation guide can be found on our support section.
What’s included?
- Motor: 250W brushless front hub, comes integrated in a wheel size of your choice (reaches maximum speed allowed by UK/EU regulation, i.e. 15.5mph)
- Wheel sizes available: 20", 24", 26", 27.5", 700c, 28" or 29er
- Wheel material: Double walled alloy rim with reinforced spokes to withstand extra pressure.
- Throttle: thumb type – gradual lever, the further it is pressed, the more power is provided.
- Brake compatibility: Compatible with both disc brakes and V-brakes
- Controller: 14A max current
- Cables: Motor cable and system cable (designed for simplicity and minimal wiring)
- Box: for mounting the controller (only when a battery is purchased with the system)
- Fork compatibility: Minimum 100mm between fork drop-outs (which is the vast majority of forks)
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).
While this kit is powered through the use of a throttle, you can also add a Pedal Assistance System to upgrade your kit with further functions.
Pedal Assist System Upgrades
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 Display
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 Computer (Advanced)
This is our top-of-the-range electric bike kit upgrade for those 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.
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.
Things to think about before purchasing this front drive conversion kit:
-
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 (the most common). If not, you may need to replace it and the crank arms to make your bike compatible with PAS. Consult a bike service shop if unsure.
- Alternatively, you may opt for purchasing the LED/LCD Display without the PAS if you prefer not to fiddle with your bottom bracket.
- The front forks need 100mm clearance between the drop-outs (most bikes comply).
- The fork drop-outs themselves need to be standard 10mm size. Smaller 9mm drop-outs can be filed professionally to fit the motor.
- The front motor is compatible with most disc brakes, but check your calipers and motor dimensions:
- If dimensions don’t fit, replace your disc rotor with a 180mm version. Your local bike shop can assist.
- Ensure enough room inside your frame triangle for your battery choice:

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.
