Bobber 250W 20 or 24 inch front wheel kit with 36V gourd battery

The Bobber 250W motor is available in front or rear wheel version. The characteristics are the same. The choice will go towards a rear motor for a comfort of use while the front motor has the advantage of being more easily removable.

The rear Bobber motor is equipped with a cassette body 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 motor is supplied with shim washers that will allow you to center the drive wheel in your frame.

The rear motor has a 135mm center distance while the front motor has a 100mm center distance.

You will be able to screw your brake disc with the standard 6 holes on the motor. For bikes equipped with pad brakes, don't forget to order a rim with a surfaced edge like the Road Runner which is a real 700c French made road rim.

With your wheel kit you receive a complete drive wheel in 700 (28"). All our wheels are carefully checked before shipment: spoke tension, centering, camber and runout.

For this kit the Road Runner Mach1 rim is perfect for road use. It is a semi-profiled rim with a flattened edge and eyelets, ideal for thin 23C tires and compatible with wide 25C tires for more comfort.

The spokes are of French origin and are available in two colors: raw stainless steel or black.

By choosing the French rim spoking, you benefit from a manual spoking in our workshop which will guarantee you a great fiability.

The above autonomies are mentioned for information only. We take as a basis of calculation, for consumption in mountain bikes, a consumption of 10Wh / km. This is an average reached by the majority of mountain bikers who use the motor as an assistance of 50% compared to the normal effort. Some of you will consume less and others more, but the experience of using the engine also matters. A beginner in E-MTB will consume 12Wh / km where an experienced pilot will consume 8Wh / km on the same route ...

Compact color display : Its compact size makes it perfect for the committed mountain biker. It sits on the left side of the handlebar so you won't be able to use it if you have the derailleur lever on the left side of the handlebar. 9 assistance modes.

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.

The battery is delivered with a 2A charger as standard.

If you want to halve the charging time, you can opt for the 36V 4A charger.

The torque arm is a laser-cut stainless steel part that prevents loosening of the drive wheel fixing nuts so as not to damage the frame of your bike.

Torque arm is strongly recommended for front wheel motors.
