Hello, I'm planning to get a Bakfiets Aero (part way down here http://schoolruncentre.co.uk/cargo-bike-bakfiets/) and have it fitted (by the dealer) with a Heinzmann Directpower front motor. The tricky part seems to be that the Aero model has vertical dropouts so uses an eccentric bottom bracket for chain tension, and this means that fitting a torque sensor BB (TDCM or Thun - apparently the latter is more forgiving in cable routing etc?) is either difficult or not possible.
Do you think it should be possible to fit a torque sensor into an eccentric BB housing?
The alternative is to use a PAS, but we are hoping for a torque sensor to give easier, more immediate power on hill starts and smoother, more efficient battery use.
Thanks
Sam
