I used to be able to ride as a child and teenager. Once I got a car, the bike became less necessary. I am sure that I would be able to ride again . On our up coming holiday, I will probably try bike riding again. It will be quicker than walking everywhere.
I never owned a pushbike and so I had little opportunity to learn. When I did try, I just could not 'get it' so happily resumed my favourite method of transport which is Walking!!I even would walk to and from work!!
