Tandem Kit 250W front wheel without battery

The "Donkey" motor  is a reduction motor with reinforced planetary gear and internal freewheel. This allows you to have a lot of torque and great ease of pedaling since the motor is completely disengaged when it is not powered ... You then pedal as on a traditional bicycle without the motor braking you.

The "Donkey" motor  is supplied with lock washers which will allow you to center the wheel in your frame. It can be installed on all traditional frames equipped with a front axle with 100mm center distance.

You can screw your standard 6-hole brake disc onto the motor. For bikes equipped with pad brakes, don't forget to order a rim with surfaced edges like the Kargo.

With your kit you receive a  complete drive wheel.  All our wheels are carefully radiated in our workshop by enthusiasts: spoke tension, centering, runout and runout, everything is checked before shipment.

The 36 spokes are made of stainless steel, 2.3mm in diameter, made in France.

 These French-made rims will allow you to use your kit in all conditions.

For bikes fitted with pad brakes, choose a rim with surfaced edges like the Mach1 K argo .

All connectors are waterproof and have visual keying. You can't go wrong when plugging in.

A single cable goes up from the engine to the handlebars to connect the various accessories:

2 Red connectors for brake cuts

1 Green connector for the control screen on the handlebars (display)

1 yellow connector for the accelerator (optional)

V ertical black and white display , entry level: Black and white display, it combines all the main functions. The remote selector is used to turn the system on and off and to navigate among the 9 assistance modes. The original bracket is intended for installation in the center of the handlebars, but we offer an optional stainless steel bracket on stem for mountain biking or gravel.

Compact color display : Its compact format makes it perfect for mountain biking as it is not exposed to shocks. It is positioned to the left of the handlebars and directly integrates the + / - buttons allowing you to choose from the 9 available assistance modes.  

V ertical color display  : With this display, you have access to the very best in the pedelec market. This model displays a maximum of electrical and travel parameters, has an auto-adaptive backlighting depending on the brightness and a USB port for charging a smartphone or GPS while driving. 9 assistance modes fully configurable by the user: You are free to configure the 9 modes so that your assistance best adapts to your needs. Remote selector to the left of the handlebars for better ergonomics.

On wheel motor kits which are fitted with 15A and higher controllers, you must  have a pedal sensor.  This will engage the engine and therefore the assistance of the bike.

The pedal sensor is a rotation sensor. You have to pedal to get assistance. There are several types of sensors to match 90% of the bikes on the market.

Integrated bottom bracket sensor  : For square axle bottom brackets that have a minimum clearance of 4mm between the crank and the frame.

Crank sensor with magnetic disc  : For all other bikes that do not have the minimum clearance to install an integrated sensor.

The accelerator  offers the possibility of controlling the engine without pedaling. 

In the form of a thumb trigger, the throttle can be installed on the right or left of the handlebars.

Note, however, that the accelerator is not approved for driving on a road open to traffic. 

He finds his interest on a mountain bike to help with hill starts and obstacle passages.

The brake cut-off  is an additional safety device which cuts off the power supply to the motor during braking. This is particularly useful during delicate maneuvers.

The brake cut-off comes in different forms:

The  brake handles  that replace your original handles.

The cable sensor  that is installed on the brake cable.

The magnetic sensor  to be reserved for bicycles equipped with hydraulic brakes.

The Tandem kit  is compatible with all bikes equipped with a 9x100mm or 10x100mm front wheel axle.

To be sure that the installation is possible on your bike, you must check that you have a traditional frame open with 100mm center distance.

With a ruler, measure the inside width of your frame (value A). You must have at least 100mm (10.0cm).

Then measure the frame notches (value B). You must have 9 or 10mm.
