Thanks for the reply, that's good to know. Re: the torque sensor, I read somewhere that these are fairly easy to replace, and the later sensor is apparently a different type and more reliable? When you say "run in cadence mode" does that mean similar to the Bafang motor, where the assist comes in when pedalling is detected, and the amount of assist is not dependent on pedal effort? I'm also interested in how you found the power assist worked with the original Pashley gear ratios? The Tongsheng apparently works best between about 70-80rpm cadence? 2nd gear on the hub is direct, so with the 42T crank & 20T sprocket an easy 75rpm cadence gives 12mph. That means top gear gives 15.9mph and bottom gear gives 9mph at the same 75rpm cadence. Does the motor have enough torque to drive a loaded bike up a decent hill (say 7-8% gradient) at 9mph in the torque/cadence sweetspot, while still allowing cruising under power on the flat at ~15mph? Or does the gearing need tweaking to better match the torque & cadence? (Bear in mind I'm an ok club cyclist and can ride a 10-mile TT averaging around 250W (unassisted!), I just don't want to have to ride TT efforts up hills on the way back from the shops.....) Thanks!

Hey. Those photos are great, very helpful - just what I'm looking to get to. It's been a couple of years since you did that conversion, would you mind sharing your experience since - reliability, usability, etc? Thanks Richard.
