The RedShift SM, the urban version, was unveiled this evening in San Francisco and ridden into the launch event by Chief Technology Officer, Derek Dorresteyn, a former pro racer in multiple disciplines. The unit is said to be a pre-production prototype, with production planned for 2012. The RedShift MX, the dual-sport version, is in parallel development. The models share a proprietary chassis and drivetrain, producing 40hp and weighing in at approximately 250lbs (240lbs in off-road trim). They feature fully adjustable suspension, with conventional wheel and sprocket sizes."There are decades of development in modern motocross and supermoto chassis" said Dorresteyn. "We chose to harness the best of that while taking advantage of the torque and throttle response an electric motor delivers." BRD states that this creates a familiar riding experience for seasoned motorcyclists, but one that provides riders more control, feedback, and confidence.Both versions of the RedShift use a 5.2kWh battery that should deliver about 50 miles of range based on other electric motorcycles in the market, but BRD refrained from specifying a range until further testing. Fenigstein clarified, "we expect people to ride the snot out of these in a way that hasn't been possible on previous electrics - that's going to affect the range and we want to be careful about getting the specification right."
