Yes it is certainly possible to learn to ride a bike as an adult. Although it will take more time than it would have taken you as a kid it is never too late. How long it takes varies from person to person, but don't be discouraged if it takes a few days. Here are some tips:

- Try to enjoy the learning process and don't get discouraged if it takes some time.
- Get a bike that is the correct size for you. 
- Consider getting a helmet. 
- Find a safe space to practice.
- Practice getting on and off your bike.
- Practice breaking.
- Try coasting without pedals first.

Good luck! And don't forget to have fun!

Yes you must have full use of both legs. Although if you are amputee there are options available for you as well. Would you like to know more about learning how to ride a bicycle with a prosthetic leg?
