Wow, thanks Saneagle! I have dual voltage LCD and KT Controller (7A / 15A) , so I need to look for a 48v battery.

Thanks for the info. The motor has code RM G020.250.DC 31 1. stamped on it.

Hi, I have an ebike that's got a Bafang 250w hub motor, 7A KT controller and a 36v battery. I set the LCD controller to max speed (about 40 mph i think) but the wheel won't spin faster than 20 mph when the bike is on the stand, 18 mph riding it. Is that normal what could be holding it back? Should I upgrade something to get it to about 23 - 25mph? Cheers

Hi All, I was looking at the cabling on my ebike controller and i saw a black and white wire joined together. I disconnected it, powered on the bike, the display came on but no power to the motor, then the display went off and I thought I had damaged the bike. But I reconnected the wire and it seems fine now. Does anyone know what it's for? Thanks

I checked and its Julet. The julet.cn website is down and I don't see an archive of it anywhere, it's like they have never existed... weird.

Hi All, Where can I get one of these Julet power connectors, I looked on Ebay, Aliexpress and searched Google but I can't find them anywhere. If anyone can point me in the right direction that would be great. Thanks

Did this controller also power the lights on the bike, because I don't see the connections for them. Mine is the Pulse with the battery in the down tube (not behind the seat post)

Thanks Davell! I'll check it out, but it seems to be in USD, maybe I'll look around and see if I can get it in the UK.

Yes, that's the same as me. The Volt bikes guy said that they partnered with Bafang and created there own system called SpinTech, not really sure how that affects anything, it looks like standard OEM stuff with SpinTech written on it.

Oh that's interesting! Can you give me a link to the KT kit as I think that would be an option for me. Would swapping out the controller and display be "plug and play" or would I need to solder and crimp wires? I ask because it's brand new and if I need to get it repaired/serviced I would need to swap the original parts back in for that. Can you recommend anywhere when I can read or a youtube channel that shows how the controller, display, BMS etc all work together, my hobby is electronics and computers so should be ok for me. It's deffo a Bafang motor, see the attached pic.

Hi All, I just bought a Voltbike Pulse, it has a Bafang hub motor RM G020.250.DC. I'd like it to go a little faster and I'm looking for the best way to derestrict it. I can't seem to see any service mode I can enter to adjust anything on the display. Would I need to replace the controller and display with ones that can be modified or is there another way. Thanks for any information.
