I have a Burley Bee
Plus points are:
– takes both my boys (3 and 2)
– Pretty robust but not too heavy
– you can get a QR mount so I can use it on my disk-braked bikes
Minus points
– It doesn’t fold flat (at least not easily) so storage is a bit of a pain
– It doesn’t have any suspension so I tend to stick to fairly smooth paths – they do get shaken around quite a lot in it
– The mesh cover stops twigs getting flicked in to the children’s faces but lots of dirt and dust still gets in (there is a clear rain cover you can use)
– Pretty expensive (£250 I think from memory)
