Description

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.

Electric bike kit specifications:

  • Motor: 500W gearless brushless rear hub motor, comes integrated in a wheel size of your choice.
  • Restricted to 250W and 25km/h by default as a road-legal kit
  • LCD Screen (Required to derestrict)
  • 500W mode reaches maximum speed of 32km/h (20mph) once de-restricted (requires a 36V battery)
  • Wheel size: 26inch, 700c, 28inch 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 levers: Electric levers that also cut the power when applied.
  • Controller: 22A current
  • Cables: Motor cable and system cable (designed for simplicity and minimal wiring)
  • Bag: for mounting the controller
  • Brake compatibility: Compatible with both disc brakes and V-brakes
  • Fork compatibility: 135mm between fork drop-outs (which is the vast majority of rear forks that are suitable for a derailleur)

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

A Pedal Assistance System is a device that senses your pedaling and makes your kit give automatic assistance, i.e. you do not have to press the throttle throughout your journey.

  • Pedal Assistance System with LCD Dashboard
    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.
    The LCD computer is required to unlock the full power of 500W for off-road use.

IMPORTANT: For Pedal Assistance System to fit, 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.

 

Before you buy this kit

Which kit is right for me?

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 variation 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 three 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 major differences for this kit compared to its other two counterparts:

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 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.
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.
Please note that the kit will be supplied restricted to 250W by default and will require the LCD to de-restrict it to the full 500W for off-road use.

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

– The rear drive motors are only compatible with a 3speed, 5speed, 6speed, 7speed, 8speed, 9speed or 10speed freewheels (not compatible with a cassette type sprocket, i.e. if your bike is fitted with a cassette, you can purchase a freewheel togther with your kit for it to fit). 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.

– 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.

 

Batteries

Bottle Battery

Our most lightweight and stylish battery, and the flagship identifier for our own popular Stealth and Revolver electric bicycles. Neatly disguised as a bottle, it weighs just under 2.5kg yet packs 36V 9Ah worth of cells giving a range of up to 30miles*. The bottle battery is great for you who are looking for value for money and keeping weight at a minimum.

36V/9Ah
– Suitable for our 250W and 500W motor systems
– Up to 20-30miles on one charge when used with this particular motor*
– Range could drop own to 12miles once motor is de-restricted to full power.
USB Port: None

 

Pannier Rack Battery

With its high capacity cells, the Pannier Rack Battery is all about reliability and range. Provided with its own free rack, it makes for great practical use and can be turned completely inconspicuous when covered with pannier bags.
If you intend on converting a step-through bike, this is almost certainly the most suitable option for your conversion. Available in two versions:

36V/11Ah
– Suitable for our 250W and 500W motor systems
– Up to 30-40miles on one charge when used with this particular motor*
– Range could drop down to 15miles once motor is de-restricted to full power.
-USB Port: None

Frame Battery

With its sleek design, the frame battery is made to pack an enormous amount of power in a small package. It’s mounting position on the bike down-tube creates a low centre of gravity for light manoeuvrability and an enhanced feeling of an overall lighter electric bike. Available in two versions:

36V/14Ah

– Suitable for our 250W and 500W motor systems
– Up to 35-45miles on one charge when used with this particular motor*
– Range could drop down to 20miles once motor is de-restricted to full power.
-USB Port: Active

36V/21Ah

– Suitable for our 250W and 500W motor systems
– Up to 55-65miles on one charge when used with this particular motor*
– Range could drop down to 35miles once motor is de-restricted to full power
-USB Port: Inactive

*Range mentioned are based on optimum cycling conditions and can vary depending on various factors such as mode, pedal assist settings, number of stops/starts, tyre pressure, terrain and the weight of the cyclist. Based on restricted 250W mode only.

 

Torque Arm

This is an optional extra however it’s highly recommended on higher power conversions.

Torque arms are there to help your bicycle’s dropouts (the part of the bike that holds onto the axles of the wheels) resist the torque of an electric hubmotor. Normal bicycle wheels don’t apply much torque to the bicycle dropouts. When you add a high power motor there can be much more torque applied than the the dropouts were originally designed to take.
