Thanks Goat Herder, picts are fun. Well then, the cruising speed is 30mph with a 44t rear sprocket and I weigh 180lbs. Uphills this little powerplant pulls between 20-25mph. Being a man of primarily 2-strokes all my life ie. motorcycles, stand up scooters, these motorized bicycles, I'm now sold on 4-smokes and the reasons are plenty. Build one, you'll prolly dig it! Cheers!
