    Bafang BBS 02 750w strange problem - No Power?

    Went to switch on the bike after a month or so stored in the shed, held the usual button in but nothing on the display. Then checked the 17.5 ah battery - no led lights! Thought it was maybe the battery, took it off checked again it lit up 3 bars out of four and read out 53.3 V. But when i put...

    Trying to construct a custom cassette

    In the process of putting the final touches to a second BBS build, this time the HD version, and to be honest all i would need with this thing is five cogs in the rear at the very most, the torque with the HD is something else. It`s a complete waste of time clicking through them all. There`s a...

    BBS HD build & KMC chain

    Just finishing off my BBS HD build and i`ve had an issue with a new KMC chain, it`s just too short!, 116 links - my fault really. The chainwheel is 46T and the cassette is 7 spd 11 - 34T so trying to get up onto the rear 34T is just impossible. So, should i lengthen it, would that then be a...

    Chain suggestions for the BBSHD?

    Will be expecting my BBSHD kit to arrive in a week or so, in the meantime i`m looking at a suitable chain. I also have a BBS02 build that i put a KMC X9 chain on, is there anything else you`d recommend that will take the extra torque? Should say i`ll also be replacing the cassette with a 7...

    New Smartphone app, Ebike control

    https://www.kickstarter.com/projects/608108780/eggrider-an-advanced-smartphone-app-to-control-you?ref=e30ixj Not a fan of these Kickstarter things, but this looks an interesting one specially as it will also control all Bafang motors,,,, seems ideal for my BBS02 What you all think??

    New Battery choice, 48v or 52v

    Looking for a battery replacement These two options are similarly priced, both using the Sanyo NCR18650GA 3.7V 3450mAh 10A cells. I see in the U.S. the 52v setup is more popular with the BBSHD mid drive setups, i`ll be using it presently with my BBS02 and probably later with the HD version...

    Official response from Bafang re. Motor spec.

    Theres been a lot of speculation and wild claims by certain sellers regarding the spec of Bafangs motors/controllers. This topic has been discussed both on this forum and other ebike forums. Is there a 16 FET version or not? Well yesterday i contacted Bafang for their comments on this claim...

    BBS02 chains and gears?

    Ok, those with mid-drives, what gearing do you find the best? The chainring that comes with the 8FUN kit is a 46T usually, do any find that a bit too high? Also what ratios at the back wheel the best? At the minute i have a 14T - 34T 7 speed freewheel with the 46T at the front. Ok for the hills...
