It's REALLY important to understand and accept that you will NOT be able to just hop on and scoot around on this when you first get it. It's like learning to ride a bike - impossible at first but with practice and perseverance you'll be zipping around in no time. After several aborted macho-man attempts at trying to use it in the middle of a parking lot I decided to take it slow, do it right, and headed over to a brick wall. I leaned against the wall and just went back and forth, back and forth, for about 3 hours until I started to establish a sense of balance. Then I started trying to go forward without the wall, which graduated into slow and unsteady turns, which graduated into actual driving and obstacle avoidance. Now I can ride it with just one foot, hop on and off with ease, zigzag to avoid people on sidewalks, and do all sorts of fun stuff. Trust me, when you figure it out and get some practice in it is AWESOME! Here are some key bullet points that I believe are most important when considering buying one of these: 1 It's built like a TANK! Seriously, when it wipes out or you fall off it'll rev up and precess and bounce all over the place until it times out. It'll scuff and scratch but it doesn't break. I have no qualms letting people try it because it just isn't fragile. 2 2 hour charge for 2 hour ride is pretty accurate. I haven't measured my mph but it's definitely faster than walking and maybe a bit faster than jogging. 3 I was afraid that people would make fun of me when I rode it around Boston or Cambridge but the exact opposite turned out to be true. I have had at least three cars pull over and ask if they could try it. Pulled over and with hazards on I've demoed this sucker and let people try it. Rolling around Gillette Stadium is a similar experience, everybody stops and asks what it is and says it's awesome and wants to try it. It was SO NICE when I visited Washington DC, it got me around to all the monuments and I charged it in coffee shops or my hotel. You will hear every single little kid you drive by go WOAH! LOOK AT THAT MOM/DAD! 4 It has some heft to it. You don't want to roll around, run out of batteries, and have to carry it for more than 20 minutes back. It's meant to be ridden, not hauled. 5 The insides of my legs were definitely bruised for about a week after I began using this sucker. It was not a permanent thing and it doesn't hurt at all to use now, but your legs aren't used to being pushed on there and they will get sore. It goes away. 6 I get asked a lot if it's easier if you know how to unicycle. I had several unicyclists try it the other day and the results were mixed. Three hopped on and within 5-10 minutes were riding a bit shaky, but stable around all over the place. One fell flat on her face : The center of gravity is different and you don't have the peddling rhythm to help stabilize you. They faked the peddling rhythm by weaving back and forth a bit, which eventually straightened out.
