Re: BBSHD Build with GX Eagle 1x12?

I would also recommend an 8 or 9 speed cassette swap. The BBSHD will chew up you expensive cassette, there's no way around it. I've ran my BBS02 on 5, 6, 7, 8 and 9 speed cassettes and I'd say 8 is the magic number. You could probably get by with less but 8 seems to allow me to keep the motor spun u...

Re: When Windows 7 is dead in 2020 what OS will you migrate to??

Installing Linux does not involve any programming. I'm a pretty hardcore Linux user and I haven't built a kernel from source for about a decade. Except for custom Android kernels but that's another thing entirely. I would say for sure that I spend far more time and effort keeping my Windows install ...

For stranded wire, just strip and loosely twist them together before crimping them into the connector.

Re: Unusual Motor Behavior-Who has seem this???

If you have another throttle to test it with, try that. It might just be something loose inside, or a bad solder joint in there. It's an easy thing to test, and in my experience one of the most common failures.

I've also experienced similar symptoms from bad hall sensor connections.

Re: What would the smallest possible battery to power this?

Says it needs minimum 7V, so a 3S 18650 pack of whatever is around should work fine. Even 2S should work, though it might shut off before they're empty.

Wouldn't it be easier to just carry a celllog or something similar instead? Would probably cost about the same as the battery you need.

Re: Bike For 3kw Hub Motor

Agreed. Spend the money on a quality (barely) used bike off Craigslist or something. There's tons of them, and after xmas is a pretty good time to get one as people are looking to make space for the new crap they'll also never use.

Re: Anybody ride with a BBS02 mostly unpowered?

There is a sprag clutch (fine pitch) that allows the motor to freewheel. It does have slightly more resistance than say the freewheel in your wheel but it's very minimal. It was a bit stiff when new but loosened up after a few miles.

It's fine for the relatively short amounts of time I ride it unpowered, but if it was going to be MOST of the time I'd really want to somehow deal with the weird pedal offset. That will screw with you over time.

Re: BBSHD advice before placing order

You can try the gear sensor, I did but I didn't like it at all. Maybe if I was using the PAS system it wouldn't be so bad but I found it too slow. You don't need to stop the motor to change gears, you just need to slow it down slightly to take the load off the chain. I find this happens quite natura...

Re: BBSHD model confusion

Yup. Get the cheapest one and a programming cable. You'll want the cable anyway.

I wouldn't even be surprised if they were programmed the same and just had different markings stamped on the motor for legal reasons.

But you still want the cable.

You just connect it through the main big leads, and set the charger to 1S. The JSTs are for balancing, nothing to balance charging a single cell.

Re: Battery storage locker?

Most of the info I've seen on the subject shows that Li-Ion is fine being stored at sub freezing temperatures, it just doesn't like being operated when cold. I'm not totally positive about this, but I'd say a battery at proper storage voltage that's very cold is probably extremely safe in terms of i...

Re: Problem with my B6 Imax charger

You could connect the low cell individually, and charge it as a 1S. That would be the fastest way to get it close to the other cells so you can more quickly perform the balance charge.

Re: Help with LiFePo4

29.4V is pretty much perfect full charge voltage for 8S LiFePo4, which is the normal pack configuration for 24V nominal. Are you sure it's a 7S LiFePo4 pack? I don't know if I've ever seen one before.

Edit: Just saw your last post, indicating it's not.
