Is it big enough for any back seat action? A bike has no walls. You and your passenger can spread your wings and fly.
The speed records for both are about the same, the bike obviously wins the endurance records. http://en.wikipedia.org/wiki/Cycling_records#Speed_record_on_a_bicycle Overall, counting production of the car and batteries and type of fuel used electric cars pollute the earth much more than gasoline cars so I fail to see the point of making them. Solar cars make much more sense.
^^^ you on a bicycle might go 35 MPH Maybe 150 MPH if you ride it off a cliff, achieving that speed somewhere before you hit the ground.
As I have predicted, by 2020 Americans will be on the same page in recognizing that we're sitting around the campfire, watching the embers die. This is China's century.
