The previous version of this motor "Thongsheng 1" suffered from a manufacturing problem. The main axel had grooves on both sides, that caused the break of the axel at those grooves, remaining without a pedal in the middle of nowhere. Do you know if this issue was solved. Can you make a teardown video, so we can see how the axel looks on this version? Thanx.

What did you do to mitigate thew rear derailleur cable under the BB? Every bike I've ever done has the cable guides in the way and had to be ground nearly flat to slide the motor in.

personally I stripped the plastic housing off and filed a slight groove less than 1mm deep at the lowest part of the bottom bracket, and piled in some grease

Oddly, I started doing. Doesn’t really matter too much, no one switches that gear anyway. They put it in third and leave it there forever.

What battery did you us and where did you get it ?

Hello, I am interested in "tongsheng tsdz2b" 750w, but I want to know if there are brakes for 700c racing or road bike type handlebars, or bullhorn handlebars, the brakes that cut off the current from the motor for greater safety. Can you please explain to me if they exist? I also want an accelerator and I see that they don't sell batteries... what battery should I buy? Thanks

They do sell batteries, brakes with sensors exist and you can't find them on AliExpress together with a thumb throttle

Currently starting the same project on a full suspension mountain bike. Because of the rear swing arm you are unable to use the fixing bracket that prevents rotation of the motor in the bottom bracket. Have you had any issues not installing the fixing bracket on this bike? Have you done anything to mitigate some of the risk?

I had zero issues, just make sure to tighten the lock ring every once in a while

So I did the upgrade. The motor wants to rotate ccw when looking at the right pedal crank. So the motor wants to rotate into the downtube. My lockring did eventually work loose when riding and the motor nearly broke a hole through the downtube of my aluminum bike frame. To address this I placed a shim between the downtube and the motor. 3d printed it out of ABS filament with 100% infill. Then tighten the locknut well.

I got the 36v 350w version and think it's great, goes up 20% + hills with some effort from the rider, I do have a 42tooth cassette on the back but I got a 52t on the front with adapter for the offset

You should really be using a torque wrench on those cranks

Not everyone has that kind of money for a rarely used tool. The cheap ones are often off by over 20%. For cheap: Better to use a luggage scale and calculate your lever length to get the right torque.

@@Shishou_Shi you can just get a beam type torque wrench that never needs any calibration.... I've had mine for 10 years. The click type from harbor freight is decent I use the 1/4 inch click type to rebuild small engines(rod bolts) with no issues but I had the 3/8 click type and never got it to work properly
