Grace Pro Race – e-bike [Photo credit: Gracebikes]
Designed in collaboration between Michael Hecken and Karl-Heinz Nicolai, Grace Pro e-bike is the latest racer in the e-bike category. The Nicolai brand already has an established reputation for incredibly impressive downhill and XC frames, and they’ve also recently diverged into urban and commuter bikes. The Grace frames are produced at the Nicolai factory, where most of the CNC machining for the bike is created as well.
The official line, from Grace, is that this is the world’s first street-legal e-motorbike. The bike can hit 45km/h (28mph) by spinning its rear-wheel brushless 1.3kW motor. It’ll run for up to 50km (31-miles) and do it all off a one-hour charge, powered by the li-ion batteries hidden inside the frame. The racer also features a handlebar-mounted computer with two headlights contained inside a CNC-machined block of aluminum.
Mercedes-Benz SLS AMG GT3 Gullwing
While the wait for the Mercedes SLS AMG roadster version continues on, Mercedes is making the wait a little more bearable by surprising us with Mercedes-Benz SLS AMG GT3 version. The sports car will compete in the 2011 racing season.
The body of the 2011 SLS AMG GT3 is the most significant difference from the road car starting with the aggressive front fascia and splitter to the massive rear spoiler. The hood of the race model is also very different from the normal SLS AMG with a large center cooling vent that helps to move air to cool the engine and the braking system. Along the side of the car, vents have been added to cool the rear brakes without compromising aerodynamics and all of these improvements to the overall cooling effort of the car makes it ideal for long road races.
