Are you riding your 70's vintage bike right now? I am riding an early 80's bike. For my current needs, it is probably the best thing for me, except for the low handlebars. I am not very flexible, and and thinking about swapping out the handlebars. I am riding on a paved bike lane with very low traffic, on flat terrain.

I was going to say not to worry about the accessories, but actually, there is a fair amount of essentials to buy: helmet, gloves, shorts are nice (now that I finally have a pair, I think they are worthwhile), and sunglasses, and a lock. But sorry, you said you were already stressing .

I had the 'knees rubbing my ears' experience, and the shop owner told me, "Well, inexperienced riders feel more comfortable lower to the ground." It made me unhappy that he would purposely put someone on a bike too small, rather than educate them. But I guess I can't blame him, if that get's someone to buy a bike. (Although, now I have second thoughts about going to his shop, so he's possibly lost a more discriminating customer.)

Remember, your doing this for FUN, so quit stressing . And don't feel pressured into buying a bike. Take it for granted that there is probably not one 'perfect' bike for you. Just buy what is best for the needs and style of riding you anticipate right now. And enjoy the process .
