can't decide between walking or bicycling? fear no more, because we have received a submission from a reader
who has created a vehicle which does both. the 'jump bike'
is a custom built bicycle which has no pedals and
instead is powered by running. the rider simple sits on the seat and begins to run, pushing the bike forward in the
process. once they have reached the desired speed they jump onto the bike and sit. make sure to watch the
video below and you will see why this is quite possibly the strangest way to power a bike.
