This one is a bit out there but....
I use my C5 as an altnative to my powered wheelchair or walking frame when ill. My legs work, I just don't stay upright very long due to balance loss (imagine getting sozzled and then going on the Waltzers - but lasting 1-12 weeks at a time)
So, I use my C5 for exercise and getting around, but most of the parks, the town centre (pedestrianised area) and other places I often go are a no-go area for cycles unless you want a fine.
I'm thinking of applying to register the C5 as a Class 3 Mobility Scooter - these are allowed to do 4mph on pavements and 8mph on the road. There will be some issues around the 15mph of the C5 on the road, but I reckon it's worth a shot as its already allowed to do that on the roads under motor alone.
The only stumbling block I can see at the moment is how to limit the motor speed to 4mph on pavements - any ideas?
If I can manage that, I might be able to convince the DVLA - if not, I haven't lost anything
