    Thanks again, Nealh. That looks like a decision then.

    Experience/opinions on these two batteries for Bafang BBS01 350W?

    How did your GSM "put paid to them"? Is the battery somehow physically or electrically fragile? I'd like to get several years of life from the battery I choose.

    Experience/opinions on these two batteries for Bafang BBS01 350W?

    Thank you, gentlemen. Since there is no significant difference in price here, this is starting to sound like a no-brainer. The only thing I can see that the bottom battery has going for it is a more integrated, neater design, totally outweighted by the practical advantages of the top battery...

    Experience/opinions on these two batteries for Bafang BBS01 350W?

    Thanks, Trex. I don't mind drilling a hole but I do use the on/off switch on my current battery (a bottle 8.8Ahr job left over from A QSWXK installation) and the USB port on the top one would also be useful. That's two counts for choosing the top one already. Anone else? Anyting else I should...

    Bafang 8FUN BBS01 Installation: Eclips Ebikes gives service over and above

    Yo, Dave, I also had a good experience shopping at EM3-EV http://em3ev.com in China; I shopped with them for the first time since they had the lefthand throttle in stock and therefore bought the 44T chainring that is Hebie Chainglider compatible from them too.

    Rohloff Speed 14 hub gearbox with Bafang BBS mid-motor: installation and use

    Thanks, Flecc. Actually, earlier on, back up the thread or in the material that the stupid programmer lost, I said "Bosch-Panasonic".

    Rohloff Speed 14 hub gearbox with Bafang BBS mid-motor

    A chainline of 53.5mm, I think, spot-on. You won't get it closer than that!

    Rohloff Speed 14 hub gearbox with Bafang BBS mid-motor

    Hang on a moment, Bill. If you're fitting a Rohloff gearbox to the installation you describe, with a 73mm bottom bracket, then you want zero (0mm) in spacers. In fact, you will have 2mm too far in spacers. I don't think it will matter all that much, and you can't do anything about it anyway, but...

    Rohloff Speed 14 hub gearbox with Bafang BBS mid-motor: installation and use

    I have a couple of low-mileage worn-out Shimano boxes, so I had to decide between proper German engineering that lasts forever (and comes with what is effectively a lifetime guarantee) and buying five or six Shimano and being left with nothing. It was a no-brainer, helped along at that time by...

    Rohloff Speed 14 hub gearbox with Bafang BBS mid-motor

    The next problem is the tooth count of the chainring. The motor is wide, so the chainring is dished to fit over it and give a tread (the trendies and poseurs call it the "Q factor" so they can express surprise when you don't know what it is -- it's the width over the outside faces of the cranks...

    Rohloff Speed 14 hub gearbox with Bafang BBS mid-motor

    This: Bombing down the hill at Kilbrogan The idiot software of this board just lost my complete description of the installation and use of a Bafang BBS midmotor with a Rohloff hub gearbox because it claimed it was over 10K words. What sort of a motherless programmer writes a deadend loss like...
