Question: My friend has an artificial leg and can't use a regular bike with pedals. I know this is a stupid question, but are there bikes with pedals that go up and down instead of around to get the momentum? Thank you for any information. ~Elaine

Answer: There are many types of bicycles and tricycles for mobily impaired people. There are also numerous groups, organizations and clinics in various parts of the world for mobily impaired cyclists. There are also some bike shops that will custom build a bicycle for you, according to your specific needs. Hand-powered bicycles are also available for people who can't pedal regular bikes. The best way to find somebody who deals in these types of bicycles in your area is to search the topic on the internet. You may want to enter the words 'disabled bicycles' or something similar to find the information.
