Unlike the STRiDA which was designed for portable urban transportation, the Green Shadow is built for speed. Designed by Spanish graphic and industrial design firm Mr. Onüff, the Green Shadow features an on-board computer that tracks mileage, heart rate and calories making it the sleekest exercise bike ever. The chain is encased in the body panels so no chance of a pants leg getting stuck. Stopping power is provided by front and rear disc brakes while front shocks absorb the bumps along the way. The Green Shadow was designed with strength, aerodynamics and speed in mind.
