I ride an electric scooter approx. 4 mi each way Caltrain <-> work everyday. I regularly maintain 15mph+ trip average.

Right, and the guy I was replying to was claiming that speed on a non-electric "Xootr".

Your right. Electrics can do that kind of speed but I was on a kick scooter and probably in more of a 3-4 x range and probably averaged 9mph after lights, pedestrians and the like are taken into account.

The Xootr in particular glides really really well.

If you're used to the cheapo Razor scooters, it's worlds apart, even from the larger-wheeled Razor A5.

The relative speed depends on the terrain. If you're on concrete sidewalks, like I am, I'd say it's 3x faster. If you're on asphalt, then 4x is reasonable. Downhill, 5x easily.

Is a Xootr really worth so much money? I just checked because I like the idea and they're close to 300€ here.

I got the cheaper Dash model with the narrow plastic deck for US $200. If I were going longer distances (more than a mile/1.5km) then one of the more expensive wider-deck models would definitely be worth it.

Yea, they can get up to 15-20 mph. Some areas are throttled in Austin, though, e.g., in and around UT campus.

They top out at 15 mph in SF. I wish they went faster. I am a cyclist and usually maintain close to 20 mph (not counting lights). It's kind of maddening not to be able to go 20 or 25 on them.

I averaged about half the time vs walking when I used my kick scooter regularly. Reading the next though, I think they are gaining time by linking transit hubs.

The boosted rev goes 24 mph
