Hi Susan,
Welcome to the board - I hope you'll find it a great source of comfort, support and info, as most members do. Incase you haven't already read it, Lisa T just recently created a thread called "Lots of new names around, roll call anyone?" and a load of people have introduced themselves on it - it'd be a great way to find out about everyone. Concerning your bike question, I don't have personal experience with it, I have a fear of bikes... Weird perhaps but maybe handy if you're epileptic. Gotta dash now, but welcome again to the board.
Best wishes,
Eilidh
