A vehicle with one or more wheels (usually spoked ) where the rider/ driver straddles the vehicle as a bicycle , motorcycle , tricycle , etc. It also includes other vehicles adapted from a traditional cycle where the rider/driver no longer straddles the vehicle (recumbent cycle, four-wheel side-by-side pedal powered vehicle) Obviously the distinction blurs with automobiles -- are they a cycle?
