Hi
I'm using a Permobil F5 as I need precise positioning with my muscular dystrophy, so it need to keep that wheelchair. If my arms aren't in the right place, I ll lose all strength to use the joystick. If it's too cold, I m quickly loosing my hand control, and I m not already accepting the idea of an helper 2nd stick.
I want to ride my local area beaches (French south west atlantic coast), poorly equipped for wheelchair users (there are some matresse if I was going for a swim).
How can I do it by hacking my F5 300-8 standard inner tubes or rim ?
Maybe 3d making fast coupling for second+third raw of 300-8 low pressured tires ? + Skids for freewheels
Or settle 3d printed plates to the tires so it increases ground surface ?
