The Speed Donkey kit was originally designed to electrify small 18", 20" and 24" wheels without compromising on power and speed. It will be perfect to electrify a folding bike, a scooter or a cargo bike, dual-carrier...

The Donkey motor is a robust motor, derived from the Freerider. It will offer you an exceptional torque allowing you to climb the slopes without effort.

You can screw your brake disc to the standard 6 holes on the motor.

Moteur roue kit speed donkey

With your donkey speed kit you get a complete drive wheel. All our wheels are carefully checked before shipment: spoke tension, centering, sail and false round.

Note that we do not offer an entry-level rim with this engine because of its large mass to avoid any risk of premature warping.

For bicycles equipped with brake pads, we recommend the Mach1 Kargo rim. Your wheel will be carefully radiated in our workshop.

Jante magma ozo kit speed rh 205C

For bicycles equipped with disc brakes we advise you to choose a rack on the Magma or Mad rim. These are freeride rims with reinforced walls and double eyelets. By choosing this option you benefit from a manual racking in our workshop which will guarantee you a great reliability.

Controleur kit speed rh 205c ozo

The controller has a simplified connection system to facilitate installation (See operating instructions).

The power cables are of large diameter, the number of cables is limited and the seals are reinforced to guarantee reliability at all times.

The pedal sensor

It will allow you to have pedaling assistance. You pedal, the motor starts. You stop pedaling, the motor stops.

In order to be able to benefit from several pedal assistance modes, consider taking a three-position switch or an analyst cycle in addition.

photo globale des contrôleurs

We offer you a choice of two models of pedal sensors. Check the installation side of the bottom bracket sensor on your bike: transmission or opposite transmission side.

For a better choice, we invite you to consult the instructions on the pedal sensors.

Note that our sensors have 12x magnets, allowing a response time twice as fast as models with 6 magnets.

The accelerator

The accelerator will allow you to manually dose the motor power from 0 to 100%.

It can be used alone or in parallel with a bottom bracket sensor.

We offer two types of throttle: half turn handle or thumb trigger. The question n°11 of our FAQ will allow you to choose between these two models.

Gachette mixte

Cycle Analyst option 

For technology enthusiasts, the controller is wired to receive a V2.4 (See product sheet) or V3 (See product sheet) Cycle Analyst.

The Cycle Analyst is a real on-board computer, much more sophisticated than the LCD displays that are offered with 250W, 750W wheel motor kits or bottom bracket motors.

The Cycle Analyst displays all the electrical data of your motor and battery and allows you to adjust all the parameters and control loop of your system yourself.

Cruise control option

The controller has a connector to connect a speed regulator. Accelerate to the desired cruising speed, release the throttle and the electronics regulate the engine power to maintain a constant speed.

Régulateur de vitesse

3-position switch option

If you do not take an Cycle Analyst but still want different support modes, simply plug the three-position switch into the dedicated connector on the controller to have three power modes: 30%, 60% and 100% of the max power.

Interrupteur 3 positions

eBrake /regeneration option

eBrake is not necessary for the proper operation of your actuator but offers additional safety by grounding the system during braking and is strongly recommended if you are using a cruise control.

It comes in the form of a contact brake handle for bicycles equipped with cable brakes or a magnetic contact or a simple push button for hydraulic brakes.

If you use a direct drive motor, the brake cut-off will activate regeneration to recharge the battery when braking or descending.

Torque arm

To secure your assembly, do not forget to use a torque arm (See operating instructions).

To power your kit, do not forget to use a 36V or 48V battery (See our battery offer).

Note: The ranges announced in the technical table are purely indicative; they are the low averages recorded by our customers since 2010 on hilly courses while being assisted.

As an indication, the autonomy of this kit with a battery 48V 10Ah can be 18Km for someone who does not pedal at all up to 70Km for the sportiest. An analyst cycle is a very good tool to help you manage your energy consumption.

The real autonomy will depend on different factors: mass of the pilot, effort provided by the pilot to relieve the engine, sudden or progressive accelerations, inflation pressure of the tires, unevenness of the course, outside temperature...
