They are slower generally. I know this because most bikes pass me on my daily commute. Maybe 10% of cyclists ride slower, my old bike used to have a speedometer and I averaged 18-22 mph over long distances. Also keep in mind that the motors are voltage limited at ~15mph. Near that speed, acceleration is basically zero, whereas a bike can accelerate further rather easily. Acceleration is definitely slower than a bike. Maybe half as much. The scooters are usually 250w but only ~170 makes it to the wheels. Bike riders average 200-300w output and when they first get moving people tend to put in more effort, maybe 400-500 watts. The low speed efficiency of the motors is also terrible, probably less than 100 watts to the ground below 7 mph. I get passed by bikes in straights and between lights every day, and pass only a few bikers a week myself. Lack of turn signals does suck, I hope they fix this. They should be required. I also agree about visibility and smaller wheels. I disagree about stability, the center of gravity of the vehicle is much lower, and having your body totally unconstraind with feet inches off the ground makes it far easier to bail. I've flown over the handlebars on a bike more than once because the high CG and large wheels, got severely injured once. Bailing on a scooter is easy and I don't expect anyone in decent shape to get injured because you basically hop off into a brisk run, you can't really do that on a bike. I've been riding scooters much more than most, close to 5 miles a day, and to me taking one hand off the handlebars is fairly easy. It also feels slower than a bike to me, and sometimes I'll give it a kick start for the first couple seconds. A lot of the reason they feel fast and unstable is because hardly anyone has ridden them much IMO
