Thank you so much for all the advice and encouragement everyone! It's all gratefully received, last time I owned a bike I was a child and lived in Wiltshire where I was more likely to meet a pheasant or a horse than a car, although going by another thread if I head down Sunderland Road I might meet a pheasant there too ! Being a non-driver as well I know nothing of road rules so I really do need all the help I can get!

If you see someone whizzing around Dulwich Park on a grey Tern folding bike with a huge grin on her face over the next couple of weekends it's probably me.

Once I've done the training I'll put some feedback on here for anyone else who's thinking about it.

Thanks again!
