The Mini B bike - a concept meant to offset the rise in personal vehicle transportation and instead incentivize the use of public transportation through a more personal and efficient experience, and ultimately for a cleaner planet. The Mini B bike is a small foldable bike that can be rented from the city of Tempe and be taken with you anywhere, including on other public transit vehicles around Arizona. The incentive lies within the energy produced from riding the Mini B and using that energy to reinsert into the city grid via a small removable battery to get your discounted fare.
