Who It’s For

The M1 EVO is ideal for mountain bikers, trail riders, e-bike users, and group-ride enthusiasts who want more than a basic helmet. It’s particularly well-suited for:

Group rides — seamless helmet-to-helmet communication keeps friends connected on trails without stopping or shouting.
Commuters or e-bike riders — phone calls, navigation audio, or music directly in your helmet without earbuds, while staying aware of surroundings.
Trail or adventure riding — integrated visor, rugged shell, and comfort fit make it practical for mixed terrain or multi-hour rides.
Night or low-light riding — built-in rear light adds visibility without needing extra attachments.
