Jouster in its original form.
This hoverboard doesn't have any unlockable upgrades.
Jouster is a limited hoverboard special to Prague edition. Like any other hoverboard, it protects you from crashing for 30 seconds. When crashed, the hoverboard will explode and will need to recharge for a few seconds before being used again. It resembles a horse sprinting for a battle.
It's the second new hoverboard in 2016, first being Groovy.
