Now I've got a friend trying to convince me to buy a OneWheel. I just can't justify $1500 for a weird skateboard when I could literally order an electric car on Alibaba for that much money.
I figure between legs, bikes, cars, trains and planes, we've pretty much got transportation solved. Segway tried to solve what bikes solved a hundred years earlier. But bikes are less expensive, are also really fun, and are great exercise.
