I can understand that statement, if the motors in question were from two different manufacturers, but surely Bafang measure their units in a similar fashion. The BBSHD is after all, just a beefed up BBS02.

Yes, I understand that internal gear ratios, stator windings and other factors can make a difference to the output torque, but double... Really?? The BBSHD has more torque than my Toyota Aygo. Probably why I have to rev the b****cks out of it to get anywhere lol.

I'm not looking to argue here, but I thought torque was proportional to current, so how have Bafang doubled the torque with only another 5 amps?

If that figure is to be believed. I personally think that amount of torque would destroy the drive-train very quickly.

Not personally, but drop the guys at EMPowered Cycles a line. Looks like they managed it. Specialized Stumpjumper EMPowered Cycles

Don't worry Dave, you'll have croaked it of old age long before anything like that happens :rolleyes:

+1 on the Slime tubes.

Yep, picked those up on my android tablet too. Weird lol.

Mmmmmmm, could be a browser thing. I use nothing but Firefox, although I haven't noticed it happening recently.

Do I detect a little bromance here :rolleyes:

Who cares about the figures, Anna's hot :D

Jesus dude, that was hard reading :eek:

I think I worded this thread totally wrong. It should have been more directed at the info in post #3. Anyone know why one has a fan and the other doesn't need one?

I'm probably being overcautious Dave. I've just replaced my 11.6Ah 29E 48v dolphin pack with a 12Ah 30Q 48v one. Even though they are similar battery packs, the chargers are different. The previous one being a 54.6v 2A non fan plastic charger, and the new one being a 54.6v 2A metal cased with...

Jesus, that's terrible service. '' issue would have occurred within the first couple of rides '', that's just boolsheet.

Maybe, drop them a personal e-mail that you are talking about them, and they may get the hint and back off a little. Wouldn't be fair to name and shame them on this thread though.

I was wondering, when charging my 48v pack, whether the charger provides a safety cut-off at 54.6v, as well as the battery BMS. In a hypothetical situation, where the charger didn't cut off, would the BMS kick in to save the day?
