    Scott Big Ed

    Hi, Anyone done any conversions on a Scott Big Ed fatbike? Can't find much information on it, especially looking if a BBS02 or BBSHD will fit on the bottom bracktet. Opper

    Bottom Bracket Standards and Bafang mid drive motors

    Any experience with this adapter kit? Would allow for installating a BBS02 68/73mm on a BB92 bike. I am about to buy a Giant Anthem. The specs says Praxis BB90 PressFit, but I think I've seen people using the BB90 shell adapters on them with a BBSHD 100mm. So would think this lekkie adapter...

    DIY Fix for BBS02/BBSHD Pedal/Throttle Issue

    Just been notified by em3ev they don't have any pre-2016 controllers at all, only BBS02B. So I may have to stock up if I want to keep riding my BBS02A motors.

    DIY Fix for BBS02/BBSHD Pedal/Throttle Issue

    Yeah, it seems doable the mod. It's just that I can remember that the wires are very thin from when I was making my own programming cable. Also it seems like the throttle just works in all PAS levels as long as you don't move your legs/pedals?

    They confirmed their controllers also have the problem.

    DIY Fix for BBS02/BBSHD Pedal/Throttle Issue

    Em3ev still states on their website that they sell units with full throttle on all pas levels (BBS02) https://em3ev.com/shop/bafang-48v-750w-bbs02-kit/

    DIY Fix for BBS02/BBSHD Pedal/Throttle Issue

    So which EDIT is that latest / correct one? I have read the 4 pages of that thread and it doesn't seem to mention anything about it solving throttle issues, nor for BBSHD nor for BBS02. Is it really that there is only a hardware mod fix for this? In that case I'm gonna buy some spare "version A"...

    Cube Nutrail BBSHD?

    Hi, Anyone got experience or knowledge about putting a BBSHD on a Cube Nutrail Race 2018? I was assuming a BBSHD 120mm would fit, but I read somewhere the BBS is 122mm causing issues? At the same time I saw one on facebook...

    Bottom Bracket Standards and Bafang mid drive motors

    I have my eye on a corratec full suspension mtb from 2016. The seller tells me it has a "Shimano sm-bb51” bottom bracket. I can't tell if that's something that exists, but it like a 68/73mm bottom bracket with external bearings. Any idea how this maps to the brackets mentioned above in first...

    Bottom Bracket Standards and Bafang mid drive motors

    Does this PF41 adapter affect the chainline? It's hard to see on the picture, but it looks like on the drive side the adapter pushes out the motor by 1-2mm? This might depend on the exact dimensions of the frame/bb I guess? Thinking about buying a Giant Anthem 2.

    CHEAP NEW ORIGINAL 18650 21700 BATTERY CELLS, POUCHES AND PACKS

    No worries, I'm actually happy because it means the sag is much less than I was seeing. I have a voltmeter and I checked if the voltage of the decharger aligns with the volt meter, which it does. But only in passive state. When discharging, the sag displayed on the decharging device is...

    CHEAP NEW ORIGINAL 18650 21700 BATTERY CELLS, POUCHES AND PACKS

    Unwelded, but should be unused. All of the ones that were at 4.0V are sagging to 3.4-5-ish at 1.5A. So it's consistent, not 1 or 2 bad cells. I'm using this...

    CHEAP NEW ORIGINAL 18650 21700 BATTERY CELLS, POUCHES AND PACKS

    Started working on the NCR18650A's I received. Quite a bunch of them were at 4.0V, so had to do some discharging. While doing that, I realized the voltage sag on these cells might bring me into trouble. I am building a 14s4p pack, that will be used for my commute. It will average at 6A =...

    CHEAP NEW ORIGINAL 18650 21700 BATTERY CELLS, POUCHES AND PACKS

    What's the verdict on the Panasonic NCR 18650A cells? Much cheaper than the GA cells. Looking for 14S4P at 20A max just for daily commute small light pack, so 5A per cell. These NCR18650A look good, but are they old?

    Bafang Error 21

    How did it go after that. Controller still working fine? I'm about to apply the reed sensor fix, but if the sensor problem is indicative of a controller that is about to fail I may be better of swapping the controller. Sensor is fine, tested it on another bike, so it must be the cabling or...

    Bafang BBSxx - fault finding and fixes

    I have a problem with a little squeeking sound from my BBS02 750W when turning the pedals very slowly (engine off). Not sure if you can hear it, but on my mobile phone I can hear the audio clearly: http://www.youtube.com/watch?v=4U_vuqzpTxw Can't get the youtube link to work, so here it is...
