    BOB trailer-electric assist

    Total novice when it comes to E bikes etc.. But I have seen a BOB trailer with an electric motor hub. Since I already own a BOB can you guys point me in the right direction to explore modify my BOB?

    I'll hold your Beer while you try..

    probably the same hub motor that gets used in a Brompton conversion, minus the 74->100mm fork spreading ..

    since the BOB hub was always just another front 10cm wide one..

    Any old 20" front hub motor should do the trick, with 100mm spacing.

    Except BoB trailers are 305 ISO 16" wheels .. but you get half score on agreeing on the hub width

    Oops...I've built a bob trailer with a Crystalyte 404 16" hub, but I've got too many 20" folders with conversions. Losing my marbles.

    I put a 500W Crystalyte front hub motor into the 16"wheel on my BOB trailer. The 36V lit-ion battery is mounted to the trailer deck. I've used my E-BOB since 2010 mainly for camping and have never had any issues with it. Used mainly as hill assist I regularly get 80 to 100K out of a single charge and the recharge time is only 2hrs so can recharge if needed during a long lunch while on tour.
