Key Features:
Multiple Riding Modes: The Tech-Air MX System comes pre-loaded with the default MX Mode that permits the use of the system on off-road tracks, specifically designed for Motocross riding. The system also features two additional Riding Modes ("MY RIDE 1" and "MY RIDE 2"), which can be customized by the user via the Tech-Air app selecting from the currently available Riding Modes: MX RACE, ENDURO, and RALLY. Once the MY RIDE 1 and MY RIDE 2 Riding Modes are set-up, users can easily switch between Riding Modes by pressing the button on the LED display or by using the Tech-Air app, they can also change the MY RIDE 1 and MY RIDE 2 Riding Modes if desired, by resetting them using the Tech-Air app.
MX / MX RACE Crash Detection Algorithm: Refined with thousands of hours of riding data and crashes, and fully tested by Alpinestars pro-riders in extreme racing conditions, including MXGP, AMA MX, and Supercross training environments, the crash triggering algorithm allows the system to accurately assess when to deploy the airbag ahead of an impact or other dangerous situation.
Active Airbag Protection: Upon the detection of a crash situation, a protective airbag is deployed, providing unrivaled protection to the rider with an average inflation time of 40 ms, depending on the airbag size.
System Versatility: The Tech-Air MX System can be worn over or under any properly fitting apparel with enough room to accommodate the inflation of the airbag in the event of a deployment.
Single Gas Inflator Deployment: A single gas inflator delivers one airbag deployment for guaranteed protection. After the airbag deploys, the gas inflator must be replaced before the system can be used again. The system has a quick-release cover opening that allows for rapid gas inflator replacement by users, only available in countries where gas inflator replacement by individuals is permitted by local regulations.
Battery Life and Charging Time: The Tech-Air MX System uses an integrated, certified lithium-ion battery, with a fully charged battery life of 30 hours and a recharge time of approximately four (4) hours, a one-hour charge delivers approximately eight (8) hours of riding time.
Quick-Release Cover Design: Enables rapid gas inflator replacement.
System Activation / Deactivation: Activating the Tech-Air MX is easy; simply attach the left buckle of the system to the chest protector, and an internal magnetic switch will detect the left buckle is closed and automatically turn on and activate the airbag system. Detaching the left buckle will automatically turn off and deactivate the system.
