I do recall reading some reports that if the front brake locks up, the same can happen On any single-track vehicle (bicycle, motorcycle, scooter), if the front wheel quits spinning, the overwhelming odds are that the vehicle will be lying on its side very soon. Very skilled and very experience riders can overcome this, but don't rely on it. I've seen professional racers lock a front wheel and keep going. I've done it once myself on a motorcycle (don't care to ever have to it again, because there was a lot of luck involved). Bicycle, different story for me. I've locked the front racing, and on slick pavement. Pretty sure I went down each time. I haven't lock the front on any of my scooters, and I'd rather keep it that way. Which is why ABS is so great on motorcycles: squeeze that lever with all your might, and let the computer sort it out.
