Disappointed by TSDZ2 torque-motor performance

Hi,

So I finally got the courage to order the mid drive 36v 350w conversion kit and little did I know that torque-sensing motor is not my thing at all. I was looking for zero effort pedaling and what I got was the opposite. I have to crank the assist all the way up to turbo mode (maximum assist) to even feel any proper help . I've changed the power settings to maximum but didn't feel much difference. I do regret buying this motor and not BAFANG, but I've already fitted it on to the bike and can't return it now. I bought it from aliexpress because it was also a bit cheaper than bafang. I should've done more research as all I read is everyone prefers torque-motors, I didn't quite realize why. Another thing I feel like I've failed with is the battery. I ordered it from a local vendor with warranty and not from aliexpress, but I have a feeling all they did was put a sticker on the same battery that is sold in chinese stores. And I overpaid 170 euros for it basically. The battery is 36v 12ah. I assume there is no way to convert torque sensing motor to pedal sensing? I also read that the motor can be programmed to be 500w, but I haven't tried that yet and doubt it would be of help. My only solution was to order a throttle, which now will require to get an insurance.

I've been researching this motor for 4 minutes and almost the first thing that comes up in every post is how you have to pedal and it feels like a real bike. This is why people like them, I have a Giant Quick-E with a torque motor and love it cos you still feel like you're riding a bike. You wanted a bafang BBSHD from the sounds of it.

From what I know, someone on Endless Sphere is promoting open-source firmware for TSDZ2, you might want to check it out.

Yes, but not a beginner project. Rather complex actually. A modified control and display can be purchased.

I have a TSDZ2. Given to me to ride and consider selling. First version came with no brake cutout, or throttle. Got the new display, brake levers, controller, and throttle and found the 48v a real dog performance wise. It sits on a KHS Smoothie and I let visitors use it. I thought about selling the thing for the bike and battery cost but don’t want to support it. So unless a DIY fella makes an offer and is independent enough to take care...it stays a dog ride for those n00b pals that don’t know any better. Almost true...

After rereading the OP, that would be worth upgrading. In for a penny, in for a pound! I find the throttle a dog as well.


I think for around $130 you can get the modified replacement controller and display. No soldering or flashing firmware.
