170mm Stock Cranks for Tongsheng TSDZ2

No reviews

     Stock Crank Arms for the Tongsheng TSDZ2. These Crank Arms curve about 20mm outward, as opposed to the offset crank arms of a Bafang BBS02/HD Motor which are pretty straight.

     After a stock installation on both Bafang BBS02/HD and Tongsheng TSDZ2 motor kits, the Q factor is actually not balanced/symmetrical. The Crank Arms and Pedals are not even distances away from the center/seat, or each side of the chain stay.

     PRO TIP: Use a Left Side TSDZ2 Crank Arm with a Right Side Bafang BBS02/HD Crank Arm on either motor kit for a balanced, symmetrical Q factor!
