    Bafang BBS02 overshooting/surging power, any fix?

    Basically, my BBS02 tends to overshoot the power on hills in the lower PAS modes. This is creating a surging effect, where it will apply the power to keep the motor running a certain speed, but applies too much, then settles, then surges again. Not the end of the world, but are there any tweaks...

    Bafang BBSHD 52v 1000w 28a Controller?

    I'm seeing vendors selling Bafang BBSHD 52v 1000w 28a replacement controllers. Are these just a misrepresentation of the regular BBSHD 48v 1000w 30a controllers, or actually a new controller from Bafang?

    EM3EV's battery with smart BMS

    I recently bought one of Paul's super shark batteries, fitted with a smart BMS. Excellent battery BTW, for anyone searching for their next pack. I have the 2A charger, which charges to 100%. I have one question, which I didn't want to pester Paul with, as he is a busy chap. Does a smart BMS...

    Bafang BBSxx programming software and 32/64 bit Windows?

    I have no problems running the Bafang BBSxx programming software on Windows 10 32 bit, but a friend is having problems connecting on Windows 7 64 bit. His comes up with 'error opening serial port'. He reckons it's something to do with his operating system being 64 bit, but I'm not convinced this...

    Help sourcing the correct BBS02 final drive assembly

    I need to replace my BBS02 48v 750w final drive and am aware that Bafang have changed the BBS02 design over the years. I've spotted this on Green Bike Kit, but am not sure whether mine is a version 'B' or original...

    Latest generation BBSxx motors, can they still be programmed?

    I read a post on the German pedelec forum, where someone mentioned that the latest generation of BBS01, BBS02 and BBSHD controllers can't be user programmed with the USB to green 5 pin Higo programming cable. Anyone know if this is true or not? Anyone bought one manufactured this year and...

    Converting 48v DC to 36v DC?

    Is there any reliable way, without spending mega bucks, to convert 48v DC to 36v DC, whilst maintaining a current output of at least 15 amps? I've seen buck converters for just about every voltage other than 36v :cry:

    Copper strips versus nickel strips on battery packs?

    Reference: Samsung 30Q 12Ah pack. Maximum current draw 25 amps. Would this pack built using copper strips, have any significant advantages over the same pack built using nickel strips? I've been told by the builder that the copper strips will give the batteries a much longer life. Is this...

    I thought you guys always did things big

    I always get the impression that Americans love to drive big muscle cars and SUV's, so I had to double look when I spotted this on eBay: 2013 Smart Fortwo Anyone seen one of these whizzing around in the states, or better still, actually own one?

    BBS02 controller with IRFB3077 mosfets reliability?

    Has anyone blown one of the upgraded controllers withIRFB3077 mosfets yet? Are they proving to be safer to program outside of factory parameters than the older model?

    Push button instead of throttle on BBS02?

    Has anyone implemented a single push button instead of the throttle on a BBS02? I do not want to add a throttle, but have a button I can press to override the PAS. I can then program the controller to run at a certain speed and current, for tricky off-road situations where pedaling is...

    EM3EV left hand thumb throttle on BBS01?

    I e-mailed Paul to ask if this left handed thumb throttle that he sells would work on a BBS01 kit: http://em3ev.com/store/index.php?route=product/product&path=46&product_id=200 The reason I asked is that the description states it's for the BBS02 kit and there is no mention that it is suitable...

    Quieting a Suntour XCT fork?

    Before anyone starts poo pooing this thread, I know that the fork I have on my bike is the lowest of the low and probably not worth having, but unfortunately it came with the bike. I was planning on just upgrading the fork, but it makes more sense to buy a better all round bike and that will...

    Bafang BBSxx spare parts

    Apologies if this has been posted before. Alcedo Italia appear to be adding Bafang BBSxx parts to their inventory as time goes on. I've posted these parts, because I think they are the more obscure parts to source. Thrust Bearing...

    Bafang BBSxx final drive dust and waterproof?

    Are the gears in the Bafang BBSxx fully protected from dust and water with the cover on? Does the cover have any form of gasket or seal? I nicked this piccy from teslanv. Hope you don't mind :roll:

    America moving away from gas guzzlers

    I'm not a tree hugger by any means, but it is still nice to see the American culture move away from the big monster gas guzzling trucks, and into the smaller, greener, city type cars. Mitsibishi i-Miev fully electric car And as the specs show, you don't have to go without creature comforts...

    Bafang BBS02 stock chain ring offsets?

    Having fitted and worked with a Bafang BBS02 for the last couple of days, I have noticed the reasons behind the poor chain line. You don't really spend a thought on bike geometry, until you start fitting motors. Bafang have played it safe with the offset on the 48T, otherwise the teeth have a...

    Hidden wire brake sensor on Bafang BBS02 750w

    After some good advice to steer away from rim brakes, I am probably going to compromise and settle for a bike with good mechanical disc brakes. I'm not prepared to run a Bafang BBS02 48v 750w kit without brake cut-offs. Seeing that there doesn't appear to be a satisfactory solution for plug n'...
