Re: My Bafang Ultra Mountain Bike! Frey AM1000

I've lost one of the nuts on the rear linkage from my AM1000 frame. I sent an email to Frey to ask for a replacement. Wondering if anyone has had similar experience, if anyone knows the thread size/pitch (so I can get a temporary nut until I get a replacement), or if by chance anyone has a spare. An...

Why are you selling?

Suited for what height / weight range?
Size is large - looking to get something with less power, lighter weight.

@cscscs: you simply took your Dorado Plus FLX battery and it matched with the Frey frame original mounts !?
I swapped everything over to a bare AM1000 frame, but I suspect the end caps are the same regardless.

Re: My Bafang Ultra Mountain Bike! Frey AM1000

Maybe the 52v case has been redesigned to be taller instead of wider??? But if you look closely in the unboxing video just a few posts ago you can see the extra width of the battery extending outboard of the frame on the left side. If my understanding is correct, I think Grace is saying all the bat...

Re: My Bafang Ultra Mountain Bike! Frey AM1000

Next Question TL;DR: Which display to get? Eggrider, Cycle Analyst, or Bafang C240, 500c, or SW102? What are your thoughts? I swapped out the stock display (DP C18.UART) for the 500C and like it much better. I found the C18 display obscenely large and vulnerable and the assist buttons were too sens...

Re: My Bafang Ultra Mountain Bike! Frey AM1000

I read this whole thread, and remember someone else also commenting that the 52v and 48v21ah batteries protrude further from the frame than the 48v17.4ah battery. However, Grace is telling me the battery cases are all the same. Can someone confirm this? I was planning on getting the 48v17.4ah batte...

Re: My Bafang Ultra Mountain Bike! Frey AM1000

including converting from hardtail to full-sus and shorter cranks (152mm). Both of these changes contributed to virtually eliminating crank strikes and I am now convinced that this was the root cause for the clutch failures. The stock Bafang cranks on the G510 are 175mm and include almost 20mm of e...

Should I order a spare part with the bike and if so can you point to which part in a photo?

Re: My Bafang Ultra Mountain Bike! Frey AM1000

I've given up trying to negotiate an equitable solution, and Frey will not respond to my inquiries on Alibaba messaging (which I find highly unprofessional), so it's pointless to perpetuate the banter, except I can't ignore the blatant lies in their replies, the above statement being one example.

@Deafcat and @cscscs: did you two ever get any farther with engineering a replacement to this weak link in the Ultra? Do you still feel it's necessary?

Re: My Bafang Ultra Mountain Bike! Frey AM1000

Hey guys, does the motor disengage during gear changes? I just rode a custom e bike today with a Bafang Mid Drive 48v1000w kit installed and it was quite jarring how the motor cut out when I changed gears... THanks I removed the gear sensor from my Bafang Mid Drive 48v1000w eMTB. I also removed the...

Re: Bafang M500/M600 thread

Would cutting out a piece from the midsection and welding back together an option? Any ideas why Bafang would choose a proprietary spline? Maybe they will revise that design if they realize it is a mistake.

Re: Bafang M500/M600 thread

Bafang spline and ISIS spline are not compatible. What the heck? Why on earth would Bafang do that? What is the length of the stock M600 cranks? I've got a G510 (Ultra) equipped bike and the stock cranks were the worst - 175mm long with a ridiculous amount of unnecessary material outboard of the sp...

Re: Bafang M500/M600 thread

Nice to see the Primary gear assembly is fitted with a sprag instead of the pawl-type used in the G510 (Ultra) - that is a big improvement. The wire management and controller connectors also look much improved. I've not been able to find a picture showing the wiring and connectors exiting the motor ...

Re: My Bafang Ultra Mountain Bike! Frey AM1000

There are actually two one-way clutches in the Ultra motor, a three-pawl freewheel for pedal input, and a one-way roller clutch or sprag clutch for the chainring output shaft. I've heard of that output clutch wearing or failing due to too large of a chainring and bad riding (too high of momentary t...

Re: My Bafang Ultra Mountain Bike! Frey AM1000

No question - the freewheel is the weak link. Freewheel failure has nothing to do with the assist level or the power of the motor, however, as the freewheel is only subjected to the forces applied to the pedals. If anything, higher assist levels might even mitigate the situation by reducing the for...

And the 3 pawl clutch/freehubs....you should have seen the state of the ones that were/replaced, def not made to cope with 1kw. Weakest parts of the whole bike imo and prone to eventual failure if used carelessly above eco3. No question - the freewheel is the weak link. Freewheel failure has nothin...

Good writeup on the disassembly. I've had mine apart a half dozen times or more.
