My girlfriend is just getting in to riding on the road, shes never fancied off road at all despite having mountain bike for years.
We go out for the odd ride together but she doesnt like riding close to my back wheel, or riding side by side so I just end up wheel sucking the whole way round and not getting much of a work out :D
So yes we ride together, no, it’s not the most amazing thing ever… Then again my girlfriends bike is the only one thats allowed to live in the house!
