Ebikes are big, bulky, and heavy. They are more like mopeds than bikes. This means they are not portable and transportable. However I just discovered a portable, fun replacement for an ebike. Onewheel is an electric self balancing skateboard that goes up to 20mph. It comes with a handle so carrying is possible, and it can be transported on a bus, train, plane with no hassle.
Additionally, the Onewheel develops balance in motion. This is essential to maximize athleticism. Overall I don't like ebikes, for the above mentions reasons. A Onewheel is smaller, faster, lighter, and more transportable than any ebike. Want an ebike? Look at a Onewheel first....you maybe surprised.
