    New "TSDZ2 Torque Sensor Central Motor"

    So, I rode about 45 miles today and the problem has disappeared. I'm hoping it was just a fluke when changing the main gear out. I am though, considering installing your open source firmware. I haven't read everything yet, but apparently I need a new display and have to solder the connection. Is...

    Display turns off after one second Tongsheng

    The only thing I can think of is there was an extra wire with a small connector that I can't figure out where it goes.... My first thought was that it's some kind of grounding wire or something...but I have no clue

    Display turns off after one second Tongsheng

    I installed my new tongsheng 52v 750w motor today with a u.p.p 52v 13ah battery. When I turn on the display it turns on for about a second then turns off. Any ideas why this is happening? This is my.first build so I'm learning as I go
