GearBrake provides motorcyclists the reassurance that other drivers will be able to see them in time to avoid a rear-end collision. Motorcycles are able to rapidly slow down without using the brakes by downshifting and engine braking. While this is extremely effective in slowing down the bike, it does not light the brake lights to warn other drivers. GearBrake can sense the deceleration from slowing down and automatically flash the brake lights.
