Re: My Bafang Ultra Mountain Bike! Frey AM1000

I'm hoping Ivy finds me a replacement but has anyone found an aftermarket one suitable? Apparently they need to have a boost offset so they don't foul on the frame. you mean an aftermarket crankarm ? I'm using sram ex-1 cranks with no issues whatsoever. I paired them with shimano pd-mx80 flat pedal...

Anybody put aftermarket chain ring on the ultra? Maybe 40 for single-track? There is conflicting info if it is a 5 bolt 110bcd or 130bcd.
this is 130bcd. I have a 52T wolftooth CX ring on mine. And there is still room to use an even larger CR...

Anyone know which Crank Arms I can upgrade too. Shimano E6000 or Ex1?
any ISIS-splined crank arms will do.

I have the EX1 ones and they're a nice piece of kit, with captive self extracting bolts.

Thanks for the info Ivanovitch_k, nice to know that spare parts can be a problem.. Hopfully Exess-bikes can be helpul with spares..
I would ask them beforehand. My motor supplier -Frey- cannot get parts from bafang :(

It would be interesting to know Exess stance on that matter.

Re: My Bafang Ultra Mountain Bike! Frey AM1000

nothing looks wrong there, but hard to tell without examining the gears up close (especially the movement of the pawl clutch and the needle bearing clutch). Also, your motor appear to be an early V1.0 with the white pcb and nylon gear so hopefully your replacement will be a supposedly more reliable ...

Re: EXESS HP-E180 Bafang Ultra Max Enduro bike

Won't Bafang resellers be able to source spare parts for the G510 in the same way as for BBSHD? right now I asked around a lot of BBS-series spare sellers and they all got a "we don't supply parts for this motor" from Bafang. I also hope they will revise their stance in the future, however, the pre...

Re: How much power is to much for a standard mtb?

KMC E chains are over 2x more expensive... I would be interested if they last 2x longer though. I don't know where you see them this pricey ? X11-E are ~27eur vs ~21eur for X11.93, in both 118 links. Not 2x between the two. agreed on the cassettes tho, they might not shift as well as their brand-na...

by controller he means the display, in this case a DPC-18. You can put a glass protector on it, if you don't find a suitable size amongst smartphone models, look at reflex cameras protectors. Don't bother with the crankarms, they should be affixed correctly from the factory... They are ISIS splined ...

Re: Bafang ultra upgrade to 2500watt

That's a very good news If you have access to the parts. Sent you a PM. Lots of Ultra owners, and before that Max drives, will need them once they run out of warranty or do mods like use. For the external controller it is surely doable. If you run sensorless you only need to connect to the motor pha...

Re: Bafang ultra upgrade to 2500watt

The reason you can't get those from Luna is too many of them failed at that power level. It might work if you made the main caps bigger. You would probably be better off going with an external controller. do you have more insight to these failures ? I.E was it mostly mechanical or controller ? The ...

try declic-eco in France, as a custom order. The owner is specialized in BBS repairs.

Re: Bafang ultra upgrade to 2500watt

for the R value, just enlarge the pic of the pcba I did (click on it to get the hi-res version), you can read it. Both are 5 mOhms

The main filter caps as you can see is 63V max, so it is borderline with your setup. However I believe there is enough space to fit higher V-rated caps in the casing.

Re: Bafang ultra upgrade to 2500watt

see there the controller pcba inside the G510. You need to change the R value of the two resistors acting as a shunt if you want to get the amps above 30A. This is what Luna is doing on their 2.5kW controller (and nothing else contrary to what they claim). I believe this motor is perfectly able to ...
