Re: New "Lingbei MM28.250 torque sensor mid drive"

I realized that one of the magnets sometimes shifts in the torque sensor, which leads to problems... it is not likely that the sensor spring always breaks. If anyone is working out the firmware here - it would be good to add a software adjustment to this sensor by introducing an adjustable software ...

Re: New "Lingbei MM28.250 torque sensor mid drive"

The spring works with little pressure on the pedal, it seems more like a switch than a linear sensor. To start pedaling assistance, it is necessary to put some pressure on the pedals at the beginning the problem that Metaller (forum user) had, is solved with a fine adjustment in the magnet position...

Re: New "Lingbei MM28.250 torque sensor mid drive"

...I have not perceived behaviour like the one described and shown by Metaller. Maybe I've got a different software version? My kit rather behaves like a better programmed tsdz2 while being a whole lot more dependable than these. I've broken the axle as well as the torque sensor of tsdz2 - I like t...

Re: New "Lingbei MM28.250 torque sensor mid drive"

I have shot short video in which has shown work of trottle (ok), rotation of pedals without effort (the engine twists as much as possible) and normal rotation of pedals with effort (the engine does not turn on, sometimes gives breakthroughs if to weaken effort on pedals) https://yadi.sk/i/MNKzJqOrnv...

Re: New "Lingbei MM28.250 torque sensor mid drive"

I welcome all. A few days ago I have assembled e-bike on the basis of Lingbei MM28. During the test trip it was found out that the engine gives power breakthroughs. In more detailed analysis of behavior of the engine during the trip around the cross-country terrain in various modes I have come in co...
