Re: In China

Kingfish, Did you get a chance to visit the Gardens or Canals in the Suzhou's "old city" area? I was there back in 2005. I was not on Business so I mainly remember the canals and some interesting local dishes. I stayed in a canal side hotel for a few nights. It was actually more like a room for rent...

Re: Can epoxy withstand the torque of a hub motor axle?

...If you can relocate the TA as described above so that it is adjacent to the side cover on the drive side where you have a beefy and very short axle shoulder very close to the stator - the protruding axle stubs should experience minimal (if any) torque and adapter assembly should be reduced to be...

Re: Can epoxy withstand the torque of a hub motor axle?

...... I would look at a redesign to separate the axle adapter and TA functionality. .... That is probably the best answer. All of my broken axles are likely related to the fact that I am using the adapter threads as TA's. Like you said, I probably should design a TA that is separate from the adapt...

Can epoxy withstand the torque of a hub motor axle?

For my first eBike I decided to go with a 2WD from components. So far I have snapped 1 rear and 2 front axles, all within a few 100 km. I have the problem with the rear axle solved. Now I need to design a solution for the front 20mm axle-fork. Follow the various views of design below you will see th...

Re: Single-speed e-bike?

I went with a SS on my first eBike and I have a CST Bafang. I am very happy with the setup. I try to get myself to pedal on starts and up hills, but I usually just floor both throttles and sit there. I don't want gears unless I go with a mid-drive. http://endless-sphere.com/forums/download/file.php?...

Re: My first eBike build: DH 2WD in China

Your build is so clean; if you have enough torque/power to snap both axles, maybe time to consider a non-hub build...Far be it from me to give you advice, but I noticed in one of your first pics the wire loom coming straight up from your front hub motor. If this is still the case, you could create ...

How to remove the front wheel:

1) Remove the forks.
2) Remove the fork brace adapter.
3) Remove the 2 TA's
4) Remove the flange adapters. They are threaded and have wrench flats.

Wheel is off!

Re: Fork brace seems unnecessary

Neat. The only thing I'd do is have 2 bolts either side of your cut just in case one bolt works loose. Good idea...but I just got this bike back together. Think what I have to do to get that brace off :roll: here is a look at it installed: http://endless-sphere.com/forums/download/file.php?mode=vie...

She is running again. I went for a 20km ride and decided to check the axles for any sign of trouble. I found all the nuts were no longer tight. I checked them several times before the ride. So new moters must have the bearing not fully pressed in. I suspect that contributed to why my axles snapped i...
