Hey guys, well as far as speed and range go....I'm averaging around 24 MPH. Range is unknown thus far. The farthest I've ridden it is 13.5 miles and it seemed to have plenty of juice left. Planning on acquiring a meter soon. It's sort of like asking how far can you go on a gallon of gas. It depends on the terrain, the wind, MPG, weight of rider, how much you peddle. I believe I'll have about a 25 mile range with the way I ride and pedal. We'll see.
