The Ambush Comp e-Bike boasts a significant amount of extended coverage and a single density foam that's been reinforced by a Composite Matrix. The reason behind this is that it manages the energy from impacts more effectively. Even with the added protection, though, it fits comfortably with our low profile and fully integrated Mindset 360 fit system. And with its five height positions, this system provides unmatched adjustment, while an integrated dial allows for on-the-fly fine-tuning. The Ambush Comp also keeps you cool with our 4th Dimension Cooling System's massive vents and exhaust ports, so you don't have to worry about overheating—even on the hottest days.
