We have just added a 29T Drive Gear Upgrade kit that fits the Yuneec Ego & Ego 2 electric skateboards. This drive gear increases your top speed to 15mph | 24kph. If you want to keep up with many of the other electric skateboards on the market you need this upgrade kit. Also enjoy the additional wheel options our drive gears provide. Fit everything from Evolve, Abec11, Metro Boards, and even our Board Bumper wheels coming soon.
