Polly, I've got a wee-ride, you are welcome to try out my bike with it if you like. I'm 5'9' and do have to ride it a bit like Charlie Chaplin but you get used to it after a while. The baby doesn't get in the way at all, but the wee-ride seat does look pretty tiny, not sure if it would accomodate a 3 or 4 year old, unless they were quite slim. Having said that, I love having my baby at the front and being able to see her at all time, plus she always falls asleep on the board at the front that is made for snoozing. I've also still got my much-needed basket on the front of my bike despite having the wee ride on it as well.
