    Bafang BBSO2 only turning once per throttle push/PAS rotation

    For anyone experiencing the same symptoms, I fixed this by flashing the firmware to the default.

    Bafang BBSO2 only turning once per throttle push/PAS rotation

    I started it up and ran the throttle. Initial burst then just slows to a constant, very low speed. Video link to problem After 20s or so it will error with missing speed sensor but prior to that I would expect this to work somewhat. This is on Assist 9 just in case of some current limiting issues

    BBS-FW: Open Source Firmware for BBSHD/BBS02 Controller

    I have a newly purchased BBS02B (May 2023); regular config tool works; but when I connect with STC, the MCU check just hangs. It says It just hangs Any ideas?

    Bafang BBSO2 only turning once per throttle push/PAS rotation

    As the title says. I have a newly purchased BBS02 and upon first tests the throttle rotates the chainring once; you let go and press again and it rotates again. Same with PAS - cycle half a rotation, get a boost, pause and do another rotation, get another boost. No error codes on the DPC18...

    Battery with 3 pin discharge - how to wire up for 2 pin?

    Hi I have a triangle battery from EM3EV purchased many years ago which has 3 pin discharge wires: Neg(black), Pos(red) and white(?) which connected to the controller and then from the controller are 3 phase wires to a geared hub motor. I've replaced the whole kit with a BBS02 but given the...

    Simple cable tidy for the ebike

    I wanted to make a cable tidy for the buttons and controls that I got with the e3mv ebike kit. It also gave me a chance to clean up the handlebar area. Probably want to make a full dashboard eventually encompassing the cycle analyst too and frankly, just make it look cool. Anyway it's my first...

    Cycle Analyst with PAS bug [solved]

    I solved it. So just in case anyone else sees this behaviour. The problem was the fast threshold voltage setting. It was set to a high 10v/sec level which meant that when I would pedal on a restart, the software throught I was already at speed and would ramp up the voltage as quickly as...

    Cycle Analyst with PAS bug [solved]

    No I don't as I have hydraulic brakes. I did think that was one possible solution, but I feel its a 'feature' in the software too. And also as this seems to happen when crusing and I stop/start pedaling without letter the motor stop or braking suggests even more that it's a feature of the system.

    Cycle Analyst with PAS bug [solved]

    I've got a CAv3 with the 12-pole PAS (all from em3ev) with a Mac10T I've set up the torq-pas mode and it great fun to ride long distances without thinking about throttle; just feels like I'm superman However I noticed one issue: Normal case: 1. While riding, if I stop pedaling the power ramps...

    My life with a Mac8T

    Hi guys Some pics attached The bag at the back just contains work clothes and is not ebike related. Battery, controller, wiring all fitted in the frame bag. Front chain ring is 40T which allows me 90-100rpm at 45kmh. I ride a regular bike too so I'm happy with high cadence riding. fesanand...

    My life with a Mac8T

    Just to add. em3ev is where I got the parts; with Hyena supplying the original kit/instructions. I've been very happy with Paul (em3ev) service.

    My life with a Mac8T

    Hi I've not been on this site for a while but thought it might be interesting to give a long term review for those who are looking for a idea of what it is to own one. I know the top posts here are for people building insanely cool, high spec bikes, but for me who's not a mechanic/machining...

    ebike range on full charge

    LockH - lol @ headwinds :cry: Yeah, they kill speed fast. Umm, maybe I'll get a velomobile next time ;) One more thing, Heyna sold me a 2KW kit, and the kick from that is seriously awesome. Though you might never need more than 500W riding a round, that feeling of torque with 2Kw in reserve is...

    ebike range on full charge

    With a 52v, 18.5ah battery from Cellman, on a regular mountain bike, motor kit from hyena. After doing my first 1500km, I've learnt the following about my ebike. If you ride it as a bike with assist you get a LOT more range than riding it like a electrically operated vehicle with pedalling...

    LT250 charger showing wrong voltages - FIXED

    Hi all I emailed em3ev and they got back to me with instructions on how to fix this. There are 4 pots labelled (from left to right) on the top right corner VR3 VR2 VR4 VR1 They are VR3 -> I voltage setting VR2 -> II voltage setting VR4 -> 0 voltage setting VR1 -> Current setting Clockwise...

    UK Police hassle

    No hassle but I reckon if too many riders start to ride recklessly then they will clamp down. I ride 25mph max and do moderate pedalling. Not only is it a good work out, it increases range and is safer at that speed. Cars don't expect bicycles to go 30mph and it causes them to act dangerously I...

    LT250 charger showing wrong voltages - FIXED

    Hi all I've been running with my ebike for a few months and have the LT250 charger. Done about 12 cycles so far only and I was getting worried that the CA was showing a low voltage when the lights when green on the charger. I thought it was my batteries but after testing each battery one by...

    Odd behaviour in dense fog

    dev8h: On a normal ride, I start out at 57.4 and end up around 56.5 (+/- 0.5) at the end; but I'm sure I've not seen those fluctuations before while throttling. Tonight it's still cold and misty in London - Telford and Somerset seem nicer right now :D I'll wait till the weekend when the...

    Odd behaviour in dense fog

    Hi I was riding this morning to work; and it was exceptionally foggy (it's London). Unusually, it was dense enough to condensate on my glasses as well as on all the wiring from the CA/brakes/frame etc; so very humid. Temperature was around 8C Ebike worked as normal; but I noticed on the CA...

    My first e-bike build

    Yep, it is a small 32T chain ring. I've replaced that with a 38 this weekend which works better. The max I can fit on the frame is 44 though. I tend to cycling up to 25km/h under pedaling (no assist), then use the motor to push myself to 35km/h with a quick 2s burst and then just pedal to the...

    My first e-bike build

    Hi ken1645 We have great bike parking facilities - dedicated space for over 500 bikes where no one even needs to lock anything. However it's in the basement and I work on the 40th floor. I've not managed to locate and electrical socket in the bike parking area, and we're not allowed to take...
