I tried a Tongsheng TSDZ2B setup on my hardtail mountain bike. All works OK except for one problem: the straight chain line runs to between the second and third smallest rear cogs. I am using no spacers and the motor is mounted as far to the left as it will go. This leads to severe...

I order a Tongsheng TDSZ2 kit for my mountain bike. The bike is set up for 12 speed. The chainring that comes with kit only goes up to 11 speed chains. Is there a chainring that I can buy that will work fit this kit and allow me to retain my 12 speed setup? My understanding is that they use...

My husband and I ride TourEasy recumbents retrofitted with Tongsheng TSDZ2 motors and the C3 controller. After about 10, 000 miles, my husband’s controller randomly flashes “communication error 30 H”. It will flash while we continue to ride for 30-40 minutes and then stop. However, we can’t...

Can the Tongsheng TSDZ2B be installed on a bike with boost hub spacing (148mm I think) ?? Has anyone successfully accomplished this?

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 have read that the TSDZ2B motor is centered relative to the tsdz2. My question is should I stick with the cranks that came with the motor or change out the right crank to a straight crank Paul

Hello, I'm Kevin from Tracy, Ca. I've had an Ice Trike Adventure for the last eight years and I just outfitted it with a Tongsheng TSDZ2. Just did a 28 mile ride with 2,300 feet of climbs and it performed far better than I expected. I'm going to be building a solar bike trailer for charging a...

I'm Gary from Colorado Springs. I have a Bacchetta CA-1 recumbent with a Tongsheng TSDZ2 motor kit.

2 years ago I bought 2 tongsheng motors on Ali Express during singles day which is the Chinese equivalent of Black Friday. One went on my recumbent delta trike and has been working fine, it has over 1800 km's on it. The second was installed on my road bike which the wife uses. My problem is a...
