Re: Am I asking for trouble? BBS02 on carbon road frame

Just a quick update on this thread for those who commented. I never got any real conclusive answer and that's probably because there isn't one. I've used this bike daily and am now at just over 7000km Its awesome to ride on the daily commute as well as in the mountains.I am really pleased with the b...

Dapu hub motor compatible controller.

Hi Guys, I hope somebody can help. I purchased a lightweight Dapu hub motor : http://www.dapumotors.com/id-4.html?t=en-us It was sold without a working controller, and I just assumed I could get away with using a generic or KT controller. I hope I am still corrct but I am uncertain based on the numb...

Re: Bottom Bracket Standards and Bafang mid drive motors

Of course, now...there are frames using the BB30 that are not carbon fiber, but reading that story made sense to me. I had previously assumed it was just another company trying to push their new proprietary standard, so you could only get replacement parts from them, but now I believe BB30 is a goo...

Re: Am I asking for trouble? BBS02 on carbon road frame

1) The middrive installs "tightly" into the BB such that it delivers an equal amount of torque counterclockwise (from the perspective of the drive side) as it does in turning the pedals clockwise. Imagine having a giant lever like a extra-long crank that's locked into place in the BB and can't spin...

Re: Am I asking for trouble? BBS02 on carbon road frame

The carbon fiber frame is was not designed to oppose the torsional loading that the mid drive motor puts on it. If you decide to keep going this way, I would regularly inspect for cracks. I wouldn't be willing to take the risk. Thanks mystryda, I appreciate your specific feedback. Where on the fram...

I ordered this charger about a year ago online and haven't been game to try it.

Maybe its a silly newbie question, but does anybody have any t...

Re: Portable 5-8 amp charger

Thanks John61ct,

Those chargers do look nice and powerfull, but a little bulky and heavy.
Still very good for the price and I am interested to get one to keep at work.
I can enquire about postage to Pau France. Do you have a preferred courier option?

Re: Am I asking for trouble? BBS02 on carbon road frame

Thanks for your ideas guys. I've used the bike for a month now and love it. It handles really well, doesn't feel like the frame is under too much stress. You were right 2old Some individuals have situations where the BBS02 "loosened" in the BB area (if the nut and "jam" nut weren't tight enough). Ma...
