Don’t be fooled by the appearance of the Speedway Bike. It’s more than just a mountain bike with an engine. It’s engine is equivalent to a 1200 cc crotch rocket engine in a mountain bike frame, 4-stroke, 4-valve engine that runs on nitro methanol. This allows the engine to run at a higher compression, producing more horsepower. The average car has a maximum 8,000 revs where as an ice speedway bike has a maximum 14,000 revs. It has 1600 razor-sharp steel studs on its tires added for traction and if that’s not enough – there aren’t any brakes. Four laps on a speedway bike compares to 10 minutes on a motocross bike. The power (90 horse power at the back wheel) to weight ratio (the bikes weigh only 180 pounds) is something that cannot be explained. Each rider gears his bike differently with 60 to 80 toothed sprockets, which are nearly the size of the wheel itself.
