Apparently, it's one-stop if you're willing to buy 1,000 units. Is there any place to purchase Bafang's current offerings in the US? Items like the torque sensor and bluetooth compatible HMI?
I'd love to see if that torque-sensing crankset would work with a BBS02 or BBSHD. If there's one thing whose motors need, it's torque-sensing pedal assist.
