Capacity: The "12" in the name indicates a 12-liter capacity, making it a moderately sized backpack suitable for shorter trips, commuting, or day rides.

Cycling-Specific Design: The Velo 12 is likely to have features specifically tailored for cyclists, such as a bike helmet holder, reflective elements for enhanced visibility, and possibly attachment points for a safety light.

Ventilation: Deuter backpacks often incorporate ventilation systems to reduce sweating during physical activities. This feature is beneficial for cyclists who may be generating heat while riding.

Hydration System Compatibility: Many Deuter backpacks, including those designed for biking, are compatible with hydration systems. This allows cyclists to stay hydrated without having to stop and reach for a water bottle.
