I took out my Dawes Galaxy 531 Ladies bike out of the shed not sure whether I want to keep it or sell it. I bought it in 1991 to accompany my sons on their cycling trips but have not ridden it for seven years after being prescribed cardiac medication with vertigo as a side effect. I am now on better drugs and vertigo is no longer a problem, so I tried the bike on the local cycling track and actually enjoyed riding it - decided to keep it and benefit from cardiovascular exercise. The problem is that I have forgotten how to use gears, also not very confident at present taking one hand off the handlebars to move the two levers. Any advice would be greatly appreciated.
