Here's what I would do. Build it,etch that 49cc bla bla bla,then call the police department and ask them about your ride. Arrange to have them look at it. Tell them you intend on using it to go to work,save gas,ect,ect,and with their blessing ride it over there or even load it up in your pick up truck or van and drive it over there. Then see what they say and have it in writing somehow. Ask them about trail usage,maybe talk a bit about being not in great shape,maybe you may be limited disabled meaning you can't pedal for 10 miles without quitting entirely,emphasize this puppy helps you with climbing hills and with pedal assist,that this in no way takes over and that you will maintain speeds under 20 mph.
Or you can go the other route and just ride it,man. If cops stop you,fine. If they just wave at you,even better.
The one thing I would have in a trailer pusher is an electric start and some type of freewheel so that you can shut her down and coast whenever you need to like if you're in a bike trail and passing people with dogs.
It's slow but I figured on using that rear axle on that mower and get a horizontal shaft engine with centrifugal clutch right on the shaft. It will go on my trike and I'll have some type of way to lift the entire unit off the ground by way of cable for the unit will be hinged to the supporting bar above the bicycle rear axle. Since it's a trailer,the starting battery can go there too.
It would rule. Push the starter button,idle the engine then while peddling,lower the assembly via some type of control maybe a stick shift type lever attached to the bicycle frame,then take off.
I need money.
