I have a Gazelle Chamonix which doubles as the school taxi and also the bike for riding to the station when wearing a suit. Whereas my Birdy is an effortless joy to ride, and a fast one at that, I find the Gazelle a momentous effort to cycle and to my dismay, despite putting in a lot more effort than on the Birdy, I get overtaken by everyone, even those 30 years older! The Gazelle is also giving my hamstrings jip, so I guess the geometry just doesn't suit me.
As I have a front and rear childseats fitted I'm toying with getting a step-through ie woman's bike to make dismounting more stable. Does anyone have any recommendations?
