Created by New Yorker Jeff Guida, the Shareroller is the first portable electric motor drive for bike share programs in US, Canada, and the UK that also works on your own bike or scooter.

Taking ten seconds to install, and weighing only 6-7lbs, use the shareroller’s 750 Watts of power to zoom up hills and sail through a breeze on a hot day without breaking a sweat or even pedalling.

Despite the campaign failing to generate funds, fans of the product can pre-order online.
