Bafang BBS01 BBS02 puller retaining rings

This can be clearly seen in the following picture: With the help of this wrench, the two retaining rings on the axle of the Bafang BBS01 and BBS02 motor can be easily removed. This is necessary if you want to change the bearings behind them, the PAS disk, the clutch or the gearbox. This is not necessary with the Bafang BBSHD motor as there are no circlips.
