A push scooter (also known as a kick scooter) is a very handy, fast, inexpensive, pollution-free way to travel a modest distance in about one third the time it takes to walk. When you get to your destination, it collapses into something you can carry. You can get on the Metro during rush hour. You can take advantage of bike lanes, and often streets provide better surfaces for scooting than do sidewalks.
There are scooters designed for adult weights. What about safety? In the 10 years I have been using a scooter, I have fallen about 5 times. If someone had given me the following tips, I could have avoided most of these falls. 1. Get used to your scooter in a place with a smooth, crack-free surface. 2. While the scooter has a break (putting pressure on the back end), I prefer to slow myself down by absorbing impact with my free foot. This provides more stability and reduces vulnerability to the unexpected. 3. I never go so fast that I cannot simply step off the scooter to avoid a fall. 4. Seams in the pavement can be a problem, especially if they are parallel to your wheels. The wheels tend to catch and you will almost certainly fall. Gratings need to be avoided if the grid lines are in your direction of travel. 5. It is best to keep your eyes on the surface right in front of you. Topology changes rapidly. Tree roots are a problem.
Changing legs becomes one of your greatest pleasures. To change legs, step on the ground with your free leg, then step on the ground with your standing leg, then step on the scooter with your previously free leg. You may need to reduce your speed to change legs. Scooting does not provide the same "constitutional" stimulation that walking does, but it does tighten muscles, especially in the thighs and bullocks.
A scooter is also a great conversation piece. I was once asked by a young boy, about 4 years old "Where did you get your scooter?" I replied "I bought it with my own money." He then asked me if I wanted to race. I often brings stares of disbelief from teenagers, but it often makes older people (or perhaps I should say other older people) smile. It is also a conversation piece on the Metro.
I have found Razor to be a very durable brand.
