Build real-feeling rides
Coasters with your own speed, hills and loops, plus drop towers, swinging hammers and spinners. Test runs show G-forces before guests ride.
Wire the control box
Every ride needs its own system. Pick from 117 parts: controller boards, power cabinets, motor drivers, motors, sensors, brakes and emergency stops. Wire them yourself or let Bolt build it.
