    Commuter Booster - <1kg Friction Drive

    I had a piece of nylon 66 to hand at the time of the build which I knew would work and Acetal and Delrin tend to be used for bearings/bushes. Nylon 6 is too brittle and will most likely crack.

    If you make your bracket from Nylon 66 like in this tutorial it will work. http://www.instructables.com/id/Friction-drive-build-for-bikes/

    Commuter Booster - <1kg Friction Drive

    Cheers for replying Folken, Looks like you have got a pretty decent set-up, do you have a link to your build you could share or not? At first I was buzzin' about having built the friction drive but now i'm getting more used to it, I'm wanting to increase time and speed too. :D I don't know...

    Commuter Booster - <1kg Friction Drive

    at the moment it's fun, I cycled to work on it this morning and used it a few times and it performed well. Turning the throttle when I'm at 15 mph - 18 mph seems to work best. I have the ESC set to soft acceleration mode so yes speed increases gradually as I twist the throttle.

    I took the servo tester apart, see the last image. I removed the potentiometer and inserted a jumper lead from the input signal pin to the potentiometer socket centre pin location. See link and image below. http://www.endless-sphere.com/forums/viewtopic.php?f=28&t=22187&start=165#p339599

    Commuter Booster - <1kg Friction Drive

    OK project completed...for now that is. Would like to replace the nylon to black and not sprayed black and complete the profiling so that it's got rounded edges all round, and will probably get some heat treated ali too. :D

    my new off road bike!

    I remember seeing a stealth bike with a faulty display unit on eBay a few months back, I think it went for about £4k.

    Cheers that'll do. I'm currently having a crack at building the Commuter Booster on this forum.

    my new off road bike!

    Nice bike, great job. I've been looking at the stealth bomber bike but silly daft prices to buy one. How much juice do you get from the li poly batteries? I found your ebay listing today, I'll share it on my fbook page and I'll keep an eye on it see what it goes for. Good luck.
