Touring Kit 250W front wheel with frame battery 36V 250Wh to 700Wh

The "Bobber 250W" motor is a reduction motor with reinforced epicyclic 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 cassette body is compatible with Shimano and Sram 9 and 10 speed cassettes. If your bike is equipped with a 7 or 8 speed cassette, you will need to add cassette spacers.

The "Bobber 250W" 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 rear axle with 135mm 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 planed edges like the Mach1 260.

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.

For “committed” uses, we advise you to choose a rack on a mountain bike rim such as the KLIXX or the MAD. These French-made rims will allow you to use your kit in all conditions.

For bikes equipped with pad brakes, choose a rim with planed edges like the Mach1 260.

On wheel motor kits which are fitted with 15A controllers, you will need a pedal sensor. This will allow the engine to be engaged and therefore the assistance of the bicycle.

The pedal sensor is a rotation sensor. You have to pedal for 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 the power supply to the motor when 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.

This motor is compatible with screw-in freewheels.

You can retrieve the screw-in freewheel from your original wheel or buy a new one from our site and we will install it on the motor when preparing your wheel.
