"frank.e" is an electric motor aided cruiser bike. Cruiser bikes are comfortable, due to the upright sitting posture, but they have a disadvantage: cruising uphill is really exhausting. With our project we found a solution for this problem. The electric motor can be switched off if you want to drive without aid. The battery is covered by red-brown leather and can be removed easily to recharge it. The saddle can be moved almost linear to the bottom bracket thanks to a special device. This assures the same cruiser feeling for both small and tall persons.
