• Second one is a gravity bike

  • On that one, are the cranks fixed in position, or do they have a function at all? (such as a brake)

  • You are not supposed to pedal on one of those bikes.
    You go as fast as you can and as you dare.
    Maybe is just to rest the riders feet on pedals screwed on cranks instead of puting them straigth on the BB
    Bike looks incomplete, as it doesn't have grips too
