Thank you for supporting small business!

The GPR50 is a fully integrated hydration system for two-wheel adventurers. It combines in-helmet water delivery, a wireless handlebar remote, and a 50oz hydration pack with onboard controls and haptic alerts.

Within the FluidLogic app, our proprietary algorithm takes your biometrics and environmental conditions to calculate your estimated sweat loss and generate a personalized hydration plan for your ride. Vibration prompts let you know when it’s time to drink, and a quick press on the wireless remote delivers water instantly—without taking your hands off the bars.

Used by pros in racing series like SCORE Baja, US Hard Enduro, and GNCC, it delivers hydration right when it counts. The GPR50 is built for riders who push the limit—on the track, trail, or anywhere in between.
