We retrofitted the TourEasy recumbents in the fall of 2021 with the TSDZ2 motors and have ridden about 10,000 miles since then . Recently, my husband’s C3 controller starts flashing “communication error, 30H”. We do not know what is wrong as the pedal assist still works but sometimes the...

TSDZ2 motor, motor gear, or torque sensor problems? New install on an MTB; about 60km so far; 12,000mA battery. Symptoms: Motor will sometimes whine and spin very fast, but chainring moves slowly, then suddenly clunk into what seems like a larger gear when the chainring turns at normal speed...

I bought a tongsheg tsdz2 kit a couple years ago, and i'm still using it and love it. But the company I bought it from eco ebikes in nashville seems to be mothballed. The other company that I do business with, Electrify bike in jordan utah, Is no longer listing the tongsheng for sale. I...

Planning to convert my commuter bike (old 90s hardtail) to a ebike and looks like the Tongsheng TSDZ2B will be the best fit for me. But ha a few question about what kit selection and accessories to pick: Break sensor to be, or not to be? What is the benefit if I only using pedal assist...

Open-Source Firmware Version 20.1c-22 When I go to Settings/Various/Odometer and change the number, it jumps to 1,400-and-some miles when I exit "Change" mode. IIRC, I succeeded in changing the odometer value once in the past, but do not recall doing anything different. What might I be missing?

I am trying to set up my TSDZ2 w/aftermarket firmware so that the "Human Power" readout bears some relation to reality. Not having access to any of the bike power meters, I am fiddling around with Settings.Torque Sensor.Weight on Pedal and one of the Settings.Assist Levels.Power Assist values...

Stuff like Odometer, Trip A, Trip B... Are they stored in the 860c or on the motor's mobo?

Aftermarket firmware versions: > 860c: 20.1c-22 > TSDZ2: 0.20.1 Coming up on 2,000 miles, Trip A & Odometer have begun spontaneously changing. From early in the game, Trip A would occasionally get weird if power to the system was removed without shutting down first - but this is...
