I got this scooter on a whim, to see how it worked. I've ridden electric ones (and bicycle and motorcycles), but never a manual scooter. Now, keep in mind, I'm over six feet tall, and 200 lbs. This little scooter had no problem carrying me! It does what it's supposed to do - you push it, and you can coast for awhile. Going downhill, you can get going plenty fast - wheee!!! Uphill is a great workout for your legs. Now, some caveats. 1. When you assemble this puppy, be sure you take your time, get the tools they advise you to use together, and buy some grease (e.g., lithium car brake grease). Do this before you start, so you don't have to hunt for anything. I spread it out over two nights, took my time, and had zero stress. Total time for me was maybe an hour. 2. The instructions are pretty complete. If you follow them and don't rush, you should be fine. Did I say don't rush? DON'T! 3. Be sure to PAY ATTENTION to the details on the brake cable hookup. This machine has a somewhat complicated "collar" that allows you to swivel the handlebars 180 degrees, and more, for fancy tricks. What that means is that the cables don't physically connect all the way from the hand-grips to the wheels. They go through a swiveling collar. It's a neat engineering trick, but it's also not finely machined. So you'll need to take your time to understand how it works, adjust it, and set it up right - so you can stop safely. 4. Having read horror stories about bicycles and other wheeled beasts shipped out of China, I pumped up the wheels to the full 40 lbs and twirled them after bolting them to the frame. And ... grind, grind, grind. Yes, just as others have noted - the wheel bearings are pretty poor, and worse, there is not nearly enough grease to help them move. So ... you will need to take apart the wheel hubs, front and rear, and SLATHER the grease in there. Put in enough that it literally squeezes out when you screw (don't tighten!) the hub nut back down on the axle. There are no instructions on how to do this. You'll have to Google something like "greasing or lubricating bicycle or scooter wheel bearings". You do this step BEFORE you bolt the wheels onto the scooter - not after, like I did. Basically, you'll need two wrenches, one to hold the nut on one side of the axle, while you unscrew the nut on the other side of the axle. You only need to unscrew one nut on each axle, maybe 1/2" to 1" along the axle - and you can then get to both bearings. Fill each side FULL of grease, then lightly tighten the nut you undid on the axle back to where it was. You don't have to tighten them down. Finger-tight, or just a bit more should be enough. The front axle is just like the rear axle. To find out if you got it right, before you bolt the wheel onto the scooter, see if it spins freely and smoothly all by itself on the axle, without any wobble. If you are afraid to take this on, just bring the wheels to a bike shop, and they can do it for you in 15 minutes or less. The only other cautions I'd offer are that if you are as big as I am, you will have to be particular about where you put your feet. You will only get part of each shoe on the floorboard. It's made for smaller folks. Also, the brakes are OK, but you don't want to depend on them to get you out of trouble. Pretend you are riding a bicycle or motorcycle, and look out well ahead of where you are going, so you don't get surprised into a quick-stop situation. Because you likely won't stop very quickly. The brakes on this scooter are not near as good as most bicycle brakes. So, take your time, be safe, and have fun!!!
