Kumbak is a Dutch amusement ride manufacturing company.

In addition to manufacturing its own rides, the company primarily specialises in changing existing rides and attractions, originally made by other manufacturers.

Kumbak (originally Kumbak Coasters) was formed on 14 November 2001 just months after the bankruptcy of Vekoma, a roller coaster manufacturer.

[2] Kumbak's first project was to design a passenger evacuation platform for Morey's Piers' Great Nor' Easter Suspended Looping Coaster.

[3] Since then the company has performed a complete upgrade on several rides originally made by different manufacturers,[4] as well as designing their own water coaster and dark rides.
