@Neptunati it has a top speed of about 35 mph, 20 uphill. I'm 250 lbs so just a single engine struggled when I went up hills (I live in a hilly mountainous area) hence why I doubled up. It has 2 throttles and kill switches, one on each handlebar. I've put at least a couple thousand miles on the back engine and about 500 on the front and have had ZERO mechanical issues.
