    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...

    One more conversion! This time my fat bike of choice a Motobecane Nightrain Bullet with a BBSHD. Nice eight mile winter mountain ride in over two feet of snow!

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

    Ultimate BBSHD Grin Phase Runner FOC 3000W

    Thanks for the info! It looks like a 74V 50A Grin Phase Runner FOC Sinewave controller is being use on his later mod. Which controller would you recommend?

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

    Bafang brake lever NC or NO?

    A simple switch like this will work as well: https://endless-sphere.com/forums/viewtopic.php?f=28&t=62646&start=25

    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. I must admit that mountain riding can be so addictive that we have a hard time waiting for spring!

    The Best Battery Bang For Your Buck!!!

    Yes, those are the batteries that fit this PVC enclosure. The dimensions of the wood block to be used for the mold are: It is best to make the length of the wood block mold at lest 16 inches and the final length of the PVC enclosure 12 inches. You will want to make sure that the PVC pipe...

    Wow 64AH, amazing! Nicely concealed, Great build! What kind of bike is that? I don't see where you haul all of that power! The battery pack alone would weight close to 50 pounds - is that right? What is your longest trip? I believe my longest ride to be just over 50 miles off road along...

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

    The Best Battery Bang For Your Buck!!!

    Yeah, I was going to initially go with Kydex but the PVC did not need to be seamed and it just happened to be the right size. I couldn't find an aesthetically pleasing way to support the back rack on my Cannondale. Hence, I fractured and welded my frame several times and have now moved to a...

    After five BBS02 conversions over a period of eighteen months I have finally come up with what I believe to be a suitable and somewhat stealthy way to carry a LIPO battery pack on my bike. At $175.00 this battery pack also happens to be the “best bang for your buck!” This 10AH battery pack...

    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...

    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.

    This picture shows this same 42t Italian chain ring (on the inside) with the stock BBS02 ring: After 200 miles with the Italian chain ring I had some issues with chain suck so I changed it for the 36t ring that you see here: With the elimination of the Italian ring I no long run two rings...

    The Italian ring with it's offset looks like this: You simply put the Italian ring on first, then a washer or lock washed on each bolt hole as a spacer, then the stock chain ring and finally the bolts. You may need to buy some longer bolts that are 4-5mm longer.
