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

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 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

I just installed a TongSheng middrive kit and pedal assist works fine, but the throttle doesn’t work. There are 3 ports on the back of the display and I plugged my left brake into the left port and tried the throttle in both of the other ports, but it won’t engage the engine.

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...

I added a TSDZ2 to a SOMA fabrications double cross, 9-speed, downtube shifters, and cantilever brakes. The install was pretty easy and only took around 2 hours. The following YouTube video shows how to install the kit: The only extra tool I needed was a bottom bracket tool for removing my...

I live near the Oregon sand dunes so I picked up a Giant/Yukon fat tire bike. I was considering assisting it with a Revel Propulsion, since I already have one, but the Giant frame has a 120 mm wide press fit bottom bracket which will not be easy to convert to threaded bottom bracket that the...
