The Energysport is such a neat concept! While riding your bike, you can charge your gadgets and devices by the Energysport kinetic energy.
How it works is that the Energysport is attached to the hub of the wheel and while riding your bike, it amps up in kinetic energy which is then converted into electricity. The energy is stored in the Energysport, and can be used to recharge any of your gadgets or devices. What a great concept to get people riding again!
