100% Satisfaction Guaranteed

These aren’t re-decaled mountain bikes (although they certainly know how to climb in the dirt); they’re bikes built to assist their partners in keeping our streets safe while keeping themselves safe at the same time.

The PD4 does it all. Built using X6 series lightweight aluminum, the PD4 frame features a tapered internal headset and internal cable routing to keep a clean frame and its housing tucked away. Its 1x drive train provides a wide gear ratio, yet keeps things light and simple with no front derailleur and shifter to deal with. Lightweight and durable Weinmann U-28 alloy double wall rims are strong and built to last and matched to Kenda's Kwick Seven.5 tires with reflective sidewalls. On top of this, the PD4 features a Shimano 11-speed Deore XT Shadow rear derailleur and a RockShox Judy Silver suspension fork complete with a remote lockout that allows you to create a rigid fork on the fly, helping to turn your sprinting efforts into faster speeds.

Replaceable decals specific to each agency are available– police, sheriff, security, ranger, etc.
