Still, experiments lead to final products..... although very interesting and well done, still not practical for most of us.
When I ride around town, its usually between 20 and 30 miles, that's back and forth for groceries, pick up parts, or something for the house. Yeah I use it like a small truck (that's why the Harley tour pack on back), so this type of bike would be a no go for me.
My weekend rides tend to go around 150 miles, some street, but most are long roads between towns.
If I had the time and monies I would build a little "beach cruiser", that I would trailer to the beach and ride it up and down the little 15 mile stretch....
I just hope the day comes when "service stations" are no longer called "gas stations", but go back to servicing a persons vehicle. You know, like changing out the battery pack, for a recharged one that's ready to go in 10 min., and while they are at it, asking if you would like your window washed, or the bugs sprayed off your front grill. ahhhhh.....my utopia ...
