It's been a successful conversion and it rides very smoothly. Weighs about half a hundredweight but when it's rolling that's ok. Had to file the fork dropouts a little to get them to fit. Lacing up the motor into the matching rim went well. Had to fit a longer bottom bracket axle to fit the cadence sensor. A couple of wires were extended and I tried to hide as many of them in the saddlebag along with the 10ah battery. I seem to get a range of 25 miles on level 3 ( mid one) before I begin to be anxious! Yose kit from eBay. Brakes are only just ok. I use it for meandering on quiet lanes.
