Re: FREY eMTB with Bafang m600 is developing with your ideas!

@Frey, most people interested on this bike wants a 14s battery not 13s. A 14s5P would be awesome if not a 14s4P but make the battery fit slick integrated into the downtube.

@Frey, are you going to have the downtube battery option too? I want a stealth ebike.

Re: Man Gets Hit and Run Over at Vigil for Cyclist who was hit an Run and Killed

I am so getting a video camera. This just happened to me 30 minutes ago, two blocks from home, I had my left hand extended out signaling to turn left and the car behind speeds pasted me on the left, lucky that I have a side mirror I saw the car so I stop turning and he(maybe a she)speeds away.

BBS02 only has three level of assist

I just finished installing the 2017 bbs02, it only has three level of assist. Is that normal? I thought it was preset to five level of assist at the factory.

Re: DIY Fix for BBS02 Pedal/Throttle Issue

I think i am going to run into this problem too, I bought a bbs02 two month ago but not yet installed. Is this circuit small enough to fit inside the bbs02 or is it external? Looks challenging, I don't know much about electronic to make the modification.

Re: BMSBattery orders

I sent them two emails they don't respond.
d8veh could you recommend a controller for me. I have a 36v 500Watt cts motor that I want to upgrade to a sin wave controller. Should I get the S12S 25A or the S12SH 35A would be fine for more power too?

Re: Bafang and 8-Fun motors

BaFang or 8Fun means eight directions .In the Chinese culture eight directions also means many or all of the direction. Similar to the meaning of "all corner of the land" So when choosing a business name they hope their business covers all corner of the land.

Re: Struggling with BMSBATTERY motors

Once I installed the motor in the bike, I don't have that rubbing noise anymore. That rubbing noise happened during testing, it was on a stand and was not bolted down. It's reassuring to hear that headways are good batteries. The controller is a 35amp Ku123. I am going to find a long stretch of flat...

Re: Converting a hubmotor to a middrivemotor

That could be challenging, I don't know anybody with a lathe. So if I understand it correctly it is not to replace the existing shaft with a new one just grind it down. I will open it and see what it looks like. I will definitely need some parts from you crossbreak. Is this process reversible?
