When you're bragging that yours is the "world's first future-proof electric bike" then you'd better be able to back it up. The Extracycle RFA is all about the extra, a city commuter, utility- and mid-tail cargo bike compressed seamlessly into one--the RFA stands for "ready for anything". There are heaps of accessories and neat features such as the ability to easily adjust the position of the rear wheel and a choice of two powerful Bosch motors.
