You need to adjust the Keep Current, both my BBS01 and 02 were set very low which makes the assist very weak after an initial surge. Haven't done the 02 yet but throttle it and its very powerful! On the 01 set Keep Current to 60% to start with, works very well. You need to buy a programming lead...

Yes you are likely right as it still feels less than an old Bosch motor on another bike. The problem with upping the Keep Current is when you are around max speed i.e. 15 (17) mph the cutout is very abrupt and it surges continually as the power comes in and drops again. Any tips for this? I...

I too was very disappointed on first ride, but the throttle gives full power. The Keep Current was set to 20%, upping that to 60% made it run more how you would expect. The other thing is the motor's natural rpm is way lower than my usual cadence and changing to a lower gear and spinning up...

Any clues on this please :)

When I fitted a BBS01 250W I was rather shocked at how weak it was, unless you used the throttle.... Subsequent investigation, and using the programming tool, I found Keep Current was set to 20%, bumped it up to 60% and it suddenly felt as it should! However, the problem now is when you are...

What's the deal with eMTB chains, are they any better, should I use one for this 750W motor? I am guessing wear will not be any different as chains are the same width for a given gear cluster, but I note unscientifically that a KMC eMTB chain is heavier than a standard so presumably is made...

Thanks for that harrys, I am hoping for that kind of speed, any more and you really need a motorbike chassis! How many teeth on the chainring are you running? With the BBS01 I average about 15mph, pedaling reasonably hard, but that is the average so uphill can be a lot less. From what I...

Hi all, new here with some questions. My main ride has a BBS01 250W but planning on fitting a 750W BBS02 to another bike for use mainly on a private farm. My desire is to keep the bike looking as “normal” as possible as it may get used for short distances on public roads occasionally and I...
