Review: Very good motor and control system - I am impressed with the motor. The control system is more sophisticated than a Bafang or Bewo mid drive as it isn't simply a rev limited system based on power setting. The result is that the bike feels much more like a real bike. You get power assist all the way up to the speed limit - it just feels more natural. Some lazy cyclists might not like it if they don't want to pedal but I think it is better. The system can tolerate strong pedalling - I have broken other drive systems but this seems to be holding up.
Review: small inclines and when feeling too tired after poor sleep. Power and turbo setting on hills - Does the trick, the only worrying thing is play in the bottom bracket bearings. Hope manufacturers will notice this and sort it out as demands increase. A bit of an excessive vibration from the spur gears, although can't notice it while riding. Performance was satisfactory during 75km trip, was able to climb trough four hills (with 15-20km/h speeds using standard low cost 7 speed Shimano cassette on 1th and 2th gears, 700c wheels, 101kg overall weight on turbo setting) which were 170 meters in hight and with 7% incline. Was left with more or less 50% of 10.5 Ah battery level and sore quadriceps. The assist wasn't used half the time, eco and tour setting was used during headwinds, small inclines and when feeling too tired after poor sleep. Power and turbo setting on hills. Average speed 17km/h only due to riding trough towns and many roundabouts, time spent: 3 hours and 30 minutes. Motor starting could be less jerky, I guess soft start PWM isn't used on all ebikes. Torque sensing works but does seem a bit too sensitive and isn't smooth enough.

### ⭐ Useless without a battery, too much hassle trying to find one when Bafang do a complete package including battery.
*by A***. on 21 May 2017*

I would have bought this item but the option to buy a compatible battery was not given to me, Bafang sell a complete package including everything needed to do a conversion. Tongsheng's product means a lot of hassle and risk trying to find a compatible battery, why bother when Bafang do it all in one?
