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 Bafang motor is assisted by the pedal. It is the chain of your bike that will transmit all the power of the engine. It is advisable to install a reinforced chain in order to prevent the chain from breaking.

You will find reinforced chains for crank motors in the reinforced chains section.

The only specific tool you will need for installing the Bafang crank motor is the torque wrench.

Note that this tightening wrench is also used to unscrew the outer bearings of the Shimano Hollowtech bottom brackets.

Removing the original crankset from your bike may also require more standard tools such as a crank remover or a square axle bottom bracket remover.

The BBS02 crankset motor is designed to be installed on BSA standard frames, i.e. with an internal case diameter of 33.5mm (Measure A) and a length of 68mm to 73mm (Measure B)

There are two types of mounting for bottom bracket bearings, those with internal bearings and those with external bearings. In both cases, measurements are always taken at the frame level as illustrated opposite.

The measurement A corresponds to the internal diameter of the case, it is taken inside the tube edge to edge. The standard is 33.5mm. If you have more, you will need to take the appropriate adapter.

Measurement B corresponds to the length of the frame box, this is done between the two ends of the frame tube. You must have between 68mm and 73mm. If you have more (83mm, 92mm, 100mm ...) you will have to choose the BBSHD crankset motor.

To be sure that your measurement is correct, we invite you to watch the video "How to measure the bottom bracket of your bike?"
