For the ultimate alternative to walking take a look at this fine new contraption! The SoloWheel is basically an elctric powered unicycle without a seat or peddles. Well, maybe it’s not so much like a unicycle, but it’s so unique it’s hard to really compare it to anything that’s on the market.
Use it just for the fun of it or use it for short commutes to work and back. It’s extremely efficient taking only two hours to complete a full charge and that single charge will take you 15 to 20 miles.
The learning curve is basically that of learning to ride a bicycle, challenging at first but then easy once you’ve got it!
