I came across this on former Mythbusters Adam Savage’s Youtube channel. 20 MPH top speed, 35+ mile range, can get another 18 miles per day on solar charging alone. As Adam describes “It looks like a kid’s drawing of a future vehicle, but not the way that you think”.
I mean its interesting, but I would also suspect its far more effective to get an electric moped and some solar panels separately. Been a while since I looked but Horwin seem like they do some decently priced options, easily obtainable for under £3k and over 100km range. Generally 50 and 125 equivalent bikes
Just looked up Horwin, you Europeans get all the cool stuff!
