  1. Hi

    Just seen some plastic 20" wheels for sale that would look dead cool on my
    recumbent. They are the type fitted to kids bmx bikes but will take a 7
    speed freewheel. What type of bearings do they normally have, are they
    serviceable. Also what about the brake surface are special shoes needed.

    thanks

    Gary

    If all you want is looks ...

    Cheap ones have CCB, better ones have cassette bearings. There's a
    variety of axle sizes.

    Blocks like Aztecs and Kool Stops will probably work OK, but don't
    expect the stopping to be great. My personal experience with plastic
    wheels (Skyway Tuff II on a BMX that ended up with derailleur gears and
    drum brakes) is that brake modulation is poor and power fades quite
    quickly.
    But BMX brakes were never great even without mag wheels (except for the
    few that had U-brakes on alloy rims) - I suspect that's why the kids
    resorted to locking the back wheel and putting a foot down.
