Tought about it for long times, never done it! I do own a ruckus that i use in town cost zero to run and it's fast enough for the city. Many times i would have use it while being OTR. Do it you will enjoy it!
Electric go-ped would be the way to go. A real scooter like a grom or ruckus would be better if you want to do recreational riding on a 34 reset or something. But a go-ped would be something practical to use every day and would fit in the cab/under the bunk.
I've got a Vespa LX50 and man is it a joy to ride, and a great stress reliever. It's registered so I can drive it and it gets just over 62 mpg so I don't fill it up that often. I already have a Class M so I don't have to worry about any size bike but I think that anything under 50cc does not require a Class M in Pennsylvania. Even if you do have to get a Class M in your state, the fun you will get from riding around on a scooter will be priceless.
Bummer I was hoping this was a thread about hauling your scooter store mobility chair on the big road so you could see the sights !!!! Now that's the thread I am waiting on right there boys.
They'd be right at home in Philly with that lol almost ran over some moron once as I came around a curve on a 4 lane city street and they were riding their chair in the right lane like they belonged there
C-channel for the wheels, weld another cross ways @ each end with a D-ring to hook a strap to. Perhaps a piece of angle iron welded into the channel in front & behind each tire to chock them. Wouldn't take more than an hour or two to fabricate. Paint it and use some U-bolts around the frame rails to hold it in place. Loading/unloading it would be the only tricky part...either risk hurting yourself lifting it up & down, or get some ramps...which would then need to be stowed somewhere...
Been a couple years but that does sound vaguely familiar. Fortunately I don't have to run Philly anymore lol
