- They use a STM32F101C6T6 microcontroller(weeee!!)
- There is a 4 pin programming cable
Does this mean that the motor could be programmed to weigh the PAS and torque sensor differently? I'd consider this motor if so, because I would prefer it to be pure torque, or maybe pure torque for the first 4 levels, then cadence + torque in level 5. I want to be superman!
Absolutely. It is now 60% PAS and 40% torque. In the beginning I thought the torque sensor didn't work but it does work, although I think it is badly balanced for my bike.
The PAS settings seem to set the cadence speed. Higher PAS = faster supported rotation. That's basically how the bafang motors work. However, the motor only starts to push when you put force on the pedals -unlike bafang- just rotating the pedals isn't enough and that's where the torque sensor kicks in. This gives(to my impression) better control over the bike, cause sometimes you just want to pedal without going faster(for example when you're slowing down and want to switch gears when you have a derailleur).
I would like to see a different balance. I find the cadence/pedal speed a little bit too fast for my liking on every setting.
1 - 3 = pure torque -> Great when cycling with other people who don't have a motor cause you can adapt your cadence speed to them.
and 4-5 = PAS + torque -> For when you are alone and want to drive fast(ie. home to work). Still having better control over the bike than pure PAS. I do like this mode in some way as it just brings you to a semi fixed speed and is not as labour intensive as torque only. If for example you only set the torque sensitivity very high without cadence, you are constantly being pushed and your bike speed varies. PAS+Torque for commuting might be best of both worlds.
When everything works I can really recommend this motor. It's absolutely dead silent! The designers used bigger gears and all gears are helix(unlike TSDZ2). I cycled with people with other motors such as Bosch and Yamaha and you just couldn't hear this lingbei motor. The yamaha being clearly the most loud one.
The 500Watt, 48Volt motor I have pushed me to 45km/hr and 40km/hr up hill with some headwind without much effort. Pretty incredible.
