I bought two of these used for my 14yr old daughter. They were both several years old but had new batteries. I was surprised right away at the at the speed of this little thing. Id say it goes an easy 18mph with 110lb rider. The batteries held a charge for quite a while, and at 6-8hrs for charge she can usially get two rides a day on it. Its a different story when I get on it. At 260lbs I was surprised at how stable they were, don't get me wrong they still have wobbly handlebars and such, they still hold me just fine. But with me on the scooter the power is signifigantly reduced, maybe 10-12 mph, the scooter struggles pretty hard to move, and forget about going up even a slightly inclined driveway. All in all I think this is a decent scooter, I was able to download a full .pdf manual for it, there are many replacement shops online that sell parts for this thing. I don't think I would pay $300 for one of these, bu t don't let the all the negative comments impact your decision on a used one.

The X-treme X360 has good speed long range

I would recommend it
