Hi,
Happy you got it working and that you're pleased with it PhaenTa.
I finally got around to recording the sound from this motor and the Bafang. The recording is done with an old MiniDV camera with a decent external microphone. Motors are mounted to different bikes but are ridden up the same hills in same conditions;

I suppose what anoyed me the most was the noise it makes when not assisting. So I decided to open up the motor to have a closer look. Here are some pictures;

The motor is smaller than I thought! After opening the motor the quality impression I have is improved. It is very well put together, and the electrical part is done really neat. Not being a mechanic I have googled spur and helical gears and it seems a helical gear will generally produce less noise than a spur one. The TSDZ2 has a spur gear on the main shaft whereas the Bafang has a helical gear. The helical I suppose is more expensive to machine and does produce axial force which is probably why the Bafang has those weird bearing on it's main shaft.
Anyway, although there is no remedy for the noise, I have decided to replace the good old Bafang with the TSDZ2 on my main cargo bike and let it endure some proper loading. Maybe I won't need the bell as much
By the way I have the 250 W version and did try to tamper with the power adjustment settings, but no noticable change as has been posted by others.
Cheers
Lars
