Hey lazy web, my son has POTS which means his legs just go limp at random. Our house is not wheelchair accessible, he uses a cane. He likes to walk places but sometimes gets stranded by a flare-up. Obviously a bike or e-scooter is out of the question. Have you got any image references for a folding tricycle scooter?

ETA: to be clear the intended application is for going to the local shops, visiting friends, and bus trips to cinemas, malls etc.

Answering my own question: a folding tricycle scooter, which looks nothing like what I imagined such a thing ( if it existed which I now know it does) would look like.

@Unixbigot that looks awesome, and very well designed!
- spring suspension for the seat
- powered front wheel
- disc brakes
- nice & compact when folded
- centre of mass far enough back/down that it's unlikely to somersault when braking heavily, meaning it could probably stop much faster than a normal scooter
- you'd have to be careful on cornering, though, as you couldn't lean into it much. A similar design but with two wheels at the front would have much better cornering stability

My only real concern would be the longevity of the rear frame arm where the seat suspension rests in that slot. If that's aluminium, I'd expect it to suffer some damage over time from the seat load.

@Bern yeah the manufacturer’s page in that product stresses in several places that turning speed must be kept very low. Probably been some stacks already, reading between the disclaimer lines. Mr 19 is over 2m tall so I’m expecting (if this idea has, ahem, legs) to custom-build.

@Bern yea, I was considering two wheels in front, too. I’ve seen compact petrol scooters with that layout. On the farm in the 70s we had an ATV trike, those things were death machines.
