Re: Fat Tire Hi Power Off Road Spec Opinion or Advise

To plow a fattie through deep sand you need a mid drive, not a single ratio hub motor. I ride BBSHD equipped 26" fattie and it's pretty good on 40T chain ring. 30-36T might be even better?

Re: New York ebike law and potential fines & confiscation?

Thanks for the update and congratulations to you (and your lawyer) on the damage award.

Big believer here in ride cameras. It’s really the best way to gather the evidence we hope to never need.

Re: Big speed reduction after installing 3 punture proofing

30% seems awfully lot of power/speed loss for adding some Slime and different tires. Are you sure they didn't mess up the motor wiring while working on it?

Re: hall wire question. 5 or 6?

You could use one of the Hall sensor wires (usually yellow) for speedometer information to your CA V3. Or, it may already be doing that if you have a CA V3 connector from your controller. I believe you select 23 poles in the setup menu or thereabouts? As far as the white wire, use it to carry the te...

Re: Road Bike or Comfort Bike?

I wish someone had told the now unused 2qty DD (9C) hubs with broken freewheel covers I’ve owned that they were bullet proof?

Re: Road Bike or Comfort Bike?

I wouldn’t consider anything other than mid-drive anymore. I’ve had a ton of hub drives and while most were best for the day Bafang BBSHD really brought mid-drives up to the task, IMO. HD motor really doesn’t need all of the shifting and fussing with gears of the BBS02. Many BBSHD commuters need onl...

Re: Open a q128c

Problem with these type rear motors is that pedaling seriously tightens the housing cover. Maybe try some heat from a propane torch? Don't get too carried away but a little heat/expansion might release enough to get it off with your tool.

Re: BBS02 1000 mile ride, what spares would you carry?

If you're only pulling 200-300W continuous thermal issues shouldn't be a problem. Be aware where drain/vent holes exist in your BBS02. Depending on many things, water can find it's way inside and might not drain back out? I've lost a BBS02 controller to a strong stream of water kicked up by front wh...

Re: ebike battery troubleshooting

Can you temporarily bypass the BMS and power a working system?

Have you ever installed a BMS before? Was this wire for wire or was it different from the BMS you were replacing? Hopefully, you tried connecting the charger briefly even if the output was showing nothing?

Re: BBS02 1000 mile ride, what spares would you carry?

I don’t see a big need for spokes here or even cables if they're in nearly new condition but definitely a chain wear tool and probably a spare chain. Change the chain at the 1st sign of wear. Do you have a temp sensor inside your BBS02? They simply don’t have the temperature headroom of the HD and t...

Re: Middrive vs. rear hub for my first e-bike

Cargo bike? Definitely step up to BBSHD. Much more forgiving than the BBS02. I've found BB drives to be much easier to install than rear hub motors. In fact, my 1st BBS02 easily moved around to several bikes as sort of an audition. Once you have crank arm puller, BB wrench/socket tool and chain brea...

Re: Hub motor wiring (6 wires vs 8 wires?)

My guess is that's a sensorless motor and the 3 small wires are for powering a single Hall sensor for wheel speed signal.

Re: If you are building packs today, which cells to choose?

I have always found 14s LiPo to be a good number for representing "48 volts". Vmax for 14s LiPo is 58.8 V, which is roughly the same as 16s LiFePO4 58.4, which is roughly the same as four lead acid cells in series (58 V). IN all cases the voltage drops as soon as you load it up, typically around 50...

I think the GA is an all around great choice for 18650 format. The new 20-21 stuff is way too new for my tastes and will undoubtedly inflict some growing pains. RC Lipo is where I learned lithium packs but it can be difficult wrapping your head around true 13S 48V and/or 14S 52V configurations. 12S ...
