ive had debilitating arthritis since I was five and whilst I was younger I enjoyed riding a bike. Unfortunately due to degradation of my hip and lower back joints I am unable to use bikes with long cranks as my hips and back don't allow for the upwards movement.
There is some rotation and upward movement within my hips and back still - I'm able to climb stairs just about for instance.
As I say, would it be possible to adjust the crank length? Would this need to be specialist or would my local second hand dealer be able to do this?
Any help would be greatly appreciated!
