Description

The Bafang BBS02 500W is a popular motor for those wanting just a bit less power than the BBS02 750W.  It’s small motor that fits in front of your pedals, and is subtle in appearance. It provides powerful torque, high efficiency and low noise levels.  Please read out fitting guide here.

All motors are reprogrammed using the ‘Hot rod’ settings for your ultimate performance.

This is available in 42v and 36v versions – please pick.

Key information:

•  18 amp controller (built into drive system) with upgraded IRFB3077 mosfets (ie reliable)
• Replacement cable brake levers with motor cutouts (Hydraulic cutout sensors optional extra)
• Bafang thumb throttle (may be used on both sides)
• LCD Display – P850C – Full Colour
• 44/46/48T chainwheel – you choose.
• Replacement cranks (both sides!)
• Speed Sensor and magnet
• All required cables
• Additional kit required to fit to 73mm bottom bracket is supplied

Can I fit this myself?

Read our fitting guide here. If you require tools to take off your bottom bracket, pedal cranks and maybe split your chain, follow this link to purchase all of the tools. You will also require a fitting wrench which you can add as an option (above).

Can I fit a 52V battery?

We would not recommend this. If you want more power – get the BBS02 750W.

Will the Bafang BBS02 500W motor fit my bike?

This motor is designed to fit bikes with a bottom bracket of between 67mm and 73mm. The inner diameter of the bottom bracket should be 33.5mm. Most modern bikes sold in the UK meet this standard (but please check).  We have a bottom bracket guide here.

What is the optional gear sensor  for?

The gear sensor interrupts the motor when you change gear, and gives a smoother gear change.

How about the brakes?

The kit comes with a choice of replacement brake levers if you have standard brake cables,  stick on sensors if you have hydraulic brakes, or a combination of both if you have integrated brake cable brake levers (where the brake lever and gear selector are integrated into one unit). No matter what type you have, they all cut the motor when you brake so that you are not fighting the motor when trying to stop. This is a very useful safety feature!
