Re: GNG / CYC X1 Pro 3000w

I would assume that this magnet was cracked during assembly. It would be enough to have a small grain of metal or the magnet being not perfectly matched with diameter of the rotor. The crack can be almost not visible at first. This is a wrong way to put it all together, but it is fast. You don't nee...

Re: 2 Speed Xiongda hubmotor

I have just ordered this motor from Bonnie. I'm getting the 36v version for a 26" wheel. Bonnie tells me that the sun gear has been through several improvements and is now much stronger. I certainly hope so! I had heard there was an issue when some? motors locking up when they were wheeled backward...

Re: Bosch mid drive with vesc controller

Tongsheng controller is only up to 500W. This is nothing. You can run VESC 4.12 at 1200W and VESC 6 at 3000-5000W.

Re: GNG / CYC X1 Pro 3000w

Via a cycle analyst. There is more than one way to run throttle thru CA is it passthru or did you try current / power mode? Passthru is the only one that works great. I doubt you will see 100 battery amps on this motor except maybe as a very momentary peak. People making the most power are using hi...

Re: Quiet motor advice for low top speed but high torque

Actually I had a problem with mine. I had to replace a sun gear. Only because of very good customer service from Xiongda I still recommend it. If you are looking for product with no problems you better forget about buying a kit to convert a bike. They all come from Chine and all Chinese products wil...

Re: Quiet motor advice for low top speed but high torque

I installed Xiongda 2 speed on my son's trike. This hub is freewheeling and is relatively quiet. Most likely one of the best low power kits out there.

Re: 2 Speed Xiongda hubmotor

My son's trike with Xiongda 2 speed is working fine. From your photos It looks like you will need a new transmission.
How many miles did you put on that motor? Did you push it harder than recommended?

Re: New Approach to 4500W Mid Drive

Yes, everything looks great on a computer screen, but once you apply forces all bets are off. Cycloidal drive is very compact and it is perfect for an e-bike, but it has to be well made. You can't just slumdonk it and hope for the best. Making rotors out of aluminum, like in Tangent, is a joke. Prop...

Thank you for this thread. It is full of interesting and valuable info. :thumb: I'm only using throttle on my build, but because of your effort I can see that using VESC with torque sensor is doable. This is great. The only thing is that we can only go with either throttle or torque sensor and not b...
