I commute in traffic. No mountain biking use case for me. Quick stop requires a cutout for me.

I use the Minshine Brake Sensor part #MSBK130804 with road brake levers and disc and caliper brakes. It would have no issue with Cantilever or v brakes or any cable actuated brakes.

New motors are kinda noisy until they have some miles on them IMHO. Usually it's a whine that is fairly loud until the gears get some wear on them.

You can buy a bootloader at eco-ebike.com, which I recommend if you aren't handy OR Here's the wiki on building your own bootloader: https://github.com/OpenSource-EBike-firmware/TSDZ2_wiki/wiki/Flash-the-firmware-on-860C-850C-using-bootloader If your plug is 6 pin instead of the 5 pin...

It sure was for me. It got worse the more I pedaled against the lack of resistance (I tried to limp home, but the sprag clutch wasn't having it)

I replaced my failed sprag clutch with a smile on my face! Open Source for the win!

When you remove the old sprag clutch, you'll see clear bearing adhesive on the outer surface. This helps the bearing not spin when under load. The loctite or similar automotive bearing and sleeve compound are even better than the clear junk Tong Shen puts on there. I too have replaced my sprag...

So this thread had some posts about TSDZ2 wearing out standard bicycle parts in the drive train. I had the following damage to my freehub which I suspect was caused by 500W motor power plus my 250W on the smallest cog on the rear hub. The left bit is the inner race with a broken ridge, middle...

cashino discovered it by personal experience. He has pictures of the fried motor in the wiki. 85C might be conservative, but I bet it would cook off at 95C, so not SUPER conservative. True that high quality motors might tolerate high temps, but the consumer grade motor in the TSDZ2 has proven...

Nope. I suspect something is rubbing where I can't see it. Haven't found it yet

I have this problem too, which is posted unanswered in the "E-Bike Technical" section. Anyone have any ideas?

Did you resolve this? I have the same issue, and am going to inspect the case to see if there's rubbing somewhere.

My sprag clutch just died this morning. 2000 miles or 3200km on the motor with OSF the whole life of the motor. It started with a strange squeak at a non-consistent point of rotation of the cranks for probably a couple of hundred miles. Then the chain started skipping in only the most extreme...

This doesn't make sense to me. I understand 36v motor kit, however, a 36v battery usually charges to 42.0v as measured with a voltmeter. Did you measure the battery voltage with a voltmeter?

Do you know what voltage the battery is charged to? What's the voltage of the kit you bought?
