Re: Bafang BBSxx - fault finding and fixes

While ride today my BBSHD motor took off on it's own at full speed!!! I had been riding over some wet terrain for about four miles on PAS level 4 (set at 30%). I don't have the kill switches set up since I have hydraulic brakes so the only way I could stop it was to hold the start button down until ...

Re: Ultimate BBSHD Now on 88V bring it on the powerrrr!

Thanks for all the info! It looks like it would be best to get a BBSHD if I plan to go this way.

Re: Ultimate BBSHD Now on 88V bring it on the powerrrr!

As long as you monitor temperatures you'll be OK. The BBS02 runs hotter than the BBSHD and is much more prone to melting the nylon gear. I melted three in my BBS02s. I have abused my BBSHDs much more with no problems of any kind. The BBS02 phase connectors are the same as the later BBSHDs (not ande...

As I have an extra BBS02 kicking around what are your thoughts about running an external controller and higher voltage?

Yes, that's what I use. Also available from Hobby Partz and RC progressive. The silicone ones are the nicest.

Nice bike and a beautiful country KINNINVIEKID! Looks like you put in lots of mileage!

Here along the Wasatch mountain range the weather is beginning to warm up again.

Re: The Best Battery Bang For Your Buck!!!

hie2kolob, Those two bikes are some nice clean builds! And having the capability of adding more capacity to the back rack only when needed is a good way to cut down on weight. I like your new PVC battery design, great idea! I was leaning towards changing from my LIPO packs to a 18650 battery pack w...

Yes, good idea, PVC puts off a distinct odor when heated.

Re: The Best Battery Bang For Your Buck!!!

Love the box, very nice. Thanks for showing us how you form the pvc. Possibly the most interesting to me is how you can turn round pipe into a nice flat sheet. That opens up lots of possibilities. Once flat, surely you can then reheat to let it form to other shapes, like a rear fender, ventilated c...

Re: The Best Battery Bang For Your Buck!!!

Nice, I use a similar technique except with .220 acrylic sheets, sheets of foam on the inside (I use the multistar packs, need more protection), and duct tape for the angles I can't make lol. It's rarely very pretty but fitting 14s/30AH of LiPo entirely inside the frame is challenging on a small fr...

Re: 3 Cannondale BBS02 Conversions

Yes, I still run 12s lipos at 50-51v. You are right, the efficiency could be increased with 14s however the BBS02 will only handle up to 53v. So a 13s could still work and be more efficient if care was taken in charging. I find that the 12s combination to be simple to configure and the most cost eff...

The stock Bafang chain ring that I was using with the dual ring set up was the 48t. If I recall correctly I believe the bolts are 5mm.

Re: 3 Cannondale BBS02 Conversions

Hello hie2kolob, Probably you have best experiences with suiting BBS for heavy ascent. I would like to ask you few questions to clarify my point of view. - you are currently running 36t chainring and 11-42 cassette? - most of your climbing is done on PAS level 1 or 2, it means 50%-60% of your 750W ...
