Re: 2 Speed Xiongda hubmotor

I've built dozens of bikes with these motors. Never had any problems with sun gears, not even on older versions. I admit that I choose motors for my clients according to their usage and situation so this prevents breakage because of unadapted installation. If you want to be extra assured of durabili...

Re: 2 Speed Xiongda hubmotor

Yes. It is just a plain old ring/spacer. It should come with the motor, but any ring that fits does the job. On your picture there is a 145mm disc brake and freewheel version of the motor, does this correspond with the actual version you have? As I stated before, the rings are just there to center t...

Re: 2 Speed Xiongda hubmotor

It is normal that there is nothing between the inner nut and the motor on the freewheel side. On the other side, there is a thick gasket that goes a little bit inside the motor housing, pushing against the inner ring of the bearing. As all bikes are different, one often needs to play around a bit wi...

Indeed, I only use them for that. Not too heavy users, not too hard usage.
Not 1 problem occurred yet.

Re: New "TSDZ2 Torque Sensor Central Motor"

safeaschuck that is very accurate indeed. The only part I disagree is that the Chinese aren't capable to do better. I wouldn't be surprised if most parts from Bosch, Shimano, etc, are being made there too. In my humble opinion it only is cost related. Over there, they make what you pay for. Making t...

Re: New "TSDZ2 Torque Sensor Central Motor"

No such remedy for the drive side though other than better quality steel, I guess we are pushing the motor beyond what it is designed for. That is an understatement Indeed. This motor is very good for light city use but totally inappropriate for MTB. I'd even say that the max power should remain be...

Re: New

It seems that the different voltage versions of the motor use the same ampere. Like 36v = 350w and 48v = 500w, approximately both do 10A. I haven't seen a 48v 350w motor. So the temperature values will be the same but the effective power of the 48v version is about 33% higher. I might be wrong thou...

Re: New

I have no experience with 36V but I read all messages here and I would say the only disadvantage of 36V is that probably 36V motor will heat faster. I can't say why, no one yet we're able to justify this. It seems that the different voltage versions of the motor use the same ampere. Like 36v = 350w...

Re: New "TSDZ2 Torque Sensor Central Motor"

Ah yes indeed I didn't think about that. Often different wire gauge is used for different voltage.
That would be visible though when holding the motors side by side.
I only have 36v versions so I cannot check it.

Re: New "TSDZ2 Torque Sensor Central Motor"

I installed my shift sensor and wow does it shift great. The second I push my shift button the motor stops it shifts fast, smooth, and quiet. Now the problem is it powers off for about 2 seconds and about 2 revolutions at 75 RPM before the power comes back on, that's a long dead-spot. I am using an...

Re: New "TSDZ2 Torque Sensor Central Motor"

Indeed, I used the bafang crank on each and every motor I installed up till now.
Never had a client's bike where this wasn't needed.
I wonder why the manufacturer never corrected this.
Does anyone here have a well centered setup with the default crank arms?

Casainho, Do you have brake sensors instaled? Yes, I do have now. My very first time, I didn't and the blue gear wore just after 20 kms, after I did a few brakes with motor at max power settings of original firmware. The blue gear did damage to me only on that situation and after some times when my...

It's a mountain bike and I'm lightweight, about cadence at highest gear I don't know,
Is it so, that the motor stops providing power at a certain cadence?
On 26" wheels, with default 42 front and 11 rear it should do about 40km/h but you need to add some good old muscle power to reach it.

Re: New "TSDZ2 Torque Sensor Central Motor"

Ah I see, you've got a 20" back wheel. Maybe you could try a sram dual drive hub. This has direct drive on 2nd, positive (136%) demultiplication on 1st and negative (73%) on 3rd if I remember correctly. Yes it has a big impact on the speed. I've looked at hub gears and I'd like to try the cheaper o...
