The Extreme Pro features a strong steel frame and a wider steel fork for extra durability and control. The solid rubber moulded-on wheels are puncture proof meaning uninterrupted fun! As with its predecessors the Extreme 2.0 has a high ground clearance for a safe ride over those big obstacles. An internal fork locking mechanism stops the bike from over-turning resulting in a safer ride. This bike also has narrower wheels requiring a greater balancing technique.
