Recumbent Bicycles Bicycles for people with spinal problems.
A recumbent bicycle is a bike which puts the rider in a seated or supine position.
The back of the rider is supported, and the rider's legs extend forward to pedals that are at about the same height as the seat. Steering is either above- or over-seat steering (ASS or OSS) using a handlebar in front of the rider, or under-seat steering (USS) using a handlebar under the seat. The wheels are often smaller and/or farther apart than on an upright bicycle.
