I have a Gary Fisher zebrano, bought some time around 2000. It's in perfectly good nick and i'd like to get a rear child seat for it to take my little boy out on it Unfortunately, my local bike a shop thinks my old bike won't work with any seat currently on the market, due to the position of the brake cables and some 'pins' on the back wheel fork (sorry for novice description!). They thought any adaptation to fit would be unsafe. Apparently my bike won't take new model bike racks for the same reason.
I need an second hand child seat. Does anyone know a model name or anything that could start me off on eBay? Or a current model child seat that would fit? I'm not a cycling pro (sure i have given that away already!) and haven't really got a clue where or how to start looking for fittings or anything past blindly walking into a bike shop.
At the moment, it's looking like I'll need to buy a new bike for the sake of being able to fit a child seat!
Thank you in advance. Any advice appreciated!
NB. I'm not keen on seats that go in front of the cyclist for safety reasons. Also don't really like the idea of a trailer in London streets.
