These are very scary MOTOR cycles and not just for the rider!

Suppose you've got up some momentum on such a steed, the fan is pushing hard and you come hurtling around a corner to be confronted by Farmer Brown's cows. These days, you'd shut the throttle and get on the brakes. This bike doesn't have any brakes, and adjusting the throttle speed (i.e 50 mph self-contained gale) requires tinkering with the fuel-air-mix at the motor, which is two feet behind you. Hence, there's no immediately available throttle adjustment and no kill switch either, so you're taking your own meat grinder to the picnic.
