Push forward on the remote and the skates' motors move you forward, pull down and the skates will slow you down. Easy enough, right?
There's also a physical brake on the back that you can push down with your heel to help you stop, but the motors will presumably still keep moving. The jury is still out on what happens if you drop the remote while you're riding. Stop, drop and roll?
The skates come with removable training wheels to get you started because even the skates' inventor says they're not the easiest to learn how to use. If it's anything like learning how to ride a bike or use a skateboard, you may want to find a secluded place to learn how to use them. Unless of course you want your 15 minutes of fame to be a YouTube video of you face-planting in front of group of strangers. You know they'll be a remix of that.
The max speed of spnKiX is 10 miles per hour (16.1 kilometers per hour) and there is a weight limit of 180 pounds (81.7 kilograms). Unfortunately, the average American male weighs 190 pounds (86.2 kilograms), so there may be a lot of potential customers who miss out on using the skates [source: CDC].
SpnKiX are made out reinforced nylon fiber and aluminum and are powered by a rechargeable lithium battery pack. If you're thinking about using spnKiX to commute to work, you might want to consider the maximum range is 6 to 7 miles (9.7 to 11.3 kilometers) and then the battery needs to be recharged, which takes about five hours.
