    Bike Selection for Hub Kit Conversion

    I've decided to buy a bike to eventually convert with an electric hub kit (undecided between Crystalyte and BionX) but I need some questions answered before I can choose the right bike.

    The primary use of this bike will be for commute through city traffic with quite a few stop lights (sidewalk available although not always clear). I would also like it to be able to go on mild trails also although that's not necessary.

    My first question is, How easy is it to remove a [front wheel] hub kit and replace it with a standard wheel? If I did go on a trail I probably wouldn't want to risk damage or even just wear from dust on the motor. Is it completely impractical to use it for dual purpose like that? The trail use would be infrequent. Would I need to remove the speed controller as well?

    Second, assuming I wanted it for purely street use. What size tires are the hub motors available in? I'm not really interested in one of the racing cylces with ultra thin wheels but I've seen some recently that have wheel width in between standard racing cycles and mountain bikes.

    Third, many bikes I've seen have disc brakes. I assume that wouldn't work with a hub conversion kit, is that true?

    Fourth, the Crystalyte conversion I tried had a handle twist throttle. At least one of the bikes I'm considering has twist shift on both handles. I assume it's not possible to put twist **** and twist throttle on the same handle. Are there other throttle options for the Crystalyte? Also, I haven't seen how the BionX controls throttle, is it through the onboard computer that shows battery life and speed?

    Last, what do people think of the new internal shift gears? Until today I've only used traditional de-railers. I think I could get used to the internal shift ones but I'm not sure if they're actually better.

    Its easy to switch back to stock.
    Im not sure about disc.
    Traditional derailleurs I would think would still be smoother, although I could be wrong.

    Picking a bike to Kit

    There is my thread same question.\

    I got this bike in small, its like high 25's ( lbs ) in weight close to 26. Excellent deal, and I shopped EVERY bike in the same price range. The Kona Dew was close, but stock in my area was nil.

    I'm only commenting on the last couple questions. Internal gears are great for ebike. You don't need 24 gears with a motor and while riding often coast to a stop without pedaling. Internal gears allow you to shift to low for starts. It makes more sense than traditional derailer IMO.

    Most suppliers allow your choice of of thumb or twist throttle. I prefer thumb throttles but any throttle mounting can get tricky with twist shifters. Another reason I steer folks away from so many gears because you will need a twist shifter. You got a motor! 3-5 internal gears is plenty!

    good luck
