Hi Deano & Grotbag
Thanks for the advice.... TBH, the quotes were on bikes that were..... 'quite' fast....so probably not a good place to start, although if I did join the biking fraternity I wouldn't want anything too small....
The CBT it is then...are there classes for people of a more mature age only? I get the feeling I could be surrounded by lots of 16yr olds otherwise...not that I've got anything against them other than embarrasment when I fall off!!

am in Surbiton so not sure if people can recommend stuff on here but would be appreciated if I could be pointed in the right direction...
Thanks again guys

andrew
