I have a small wheeled Two Wheel Electric Bike that does 20 mph..[ conservatively...and without folling with the electronics...ahem...for forty miles...and cost less than half of the RYNO.
I can ride it on the street or on bike trails. it has enormous torque and can get off the line...very rapidly...very handy in tricky situations.
Im sure there are plenty of people in this county Marin County CA..who will buy a ryno just to show it off...
If you like your front wheel you can keep your front wheel.
Period.
Hehe.
