The Bumpy Bike concept is what started us off in Crazy Bikes
These bikes are designed with "off center" wheels which makes them "bump" up and down as you ride.
Our fleet of bumpy bikes have is proving very popular
We currently have 15 bumpy bikes - with no 2 being the same
The wheel sizes vary from 16", 20" 24" and 26"
but the amount of offset in each wheel varies
Just to be different,
we have added hi-rise bars, or
steering wheels to some bikes
