The Prevelo Alpha One is a 14-inch kids' pedal bike and the natural next step from a balance bike, engineered to make learning to pedal feel effortless. At 11.3 pounds it's remarkably light for ages 3 to 5, with a low-slung aluminum frame, a narrow kid-specific crank, dual hand brakes, and a single-speed freewheel drivetrain (no coaster brake). A Golden A' Design Award winner. Fits inseams 14 to 17.5 inches.
