Japanese based Arte Sales rolled out its new Tretta 2WD bike at last week’s Interbike. The concept has taken five years to develop and was finally introduced last year, but the company hopes to gain traction in the worldwide cycling market.
And given that the concept involves a two wheel drive system the company should be able to get through the mud, snow and just about anything else that stands in its way. The Tretta, which as shown in the photos, utilizes a unique drive chain system that delivers some of the power from the pedal stroke to the front wheel. This helps riders power through snowy roads, bad rods and assists in climbing as well as tackling rough terrain. Additional photos after the jump
