This hoverboard doesn't have any unlockable upgrades.
Daredevil is a type of hoverboard that protects from crashing for 30 seconds. When crashed, the hoverboard will explode and need to recharge for a few seconds before using again. It's in the shape of a daredevil's rocket, hence the name (or by the hoverboard's intense speed).
Daredevil Hoverboards will have a "Speed Up" ability. All Daredevil Hoverboards will automatically make you surf faster. The Daredevil is the cheapest hoverboard that has a special power. The speed of the Daredevil is the same as using a jetpack or the Hot Rod hoverboard.
