28" men's trekking bicycle TR.2825 trekking bike 24-speed Shimano Alivio RD-M3100 SGS Shadow
Functional trekking bike for everyday use & leisure
The Airtracks TR.2825 focuses on the essentials: reliable technology, comfortable handling, and practical everyday equipment. This 28-inch men's trekking bike is ideal for daily rides, leisure, and longer tours.
Shimano Alivio 24-speed gearing
The Shimano Alivio RD-M3100 SGS Shadow 24-speed gearing ensures precise and reliable shifting. This lets you ride comfortably on flat routes, in the city, and over gently hilly terrain.
AXA lighting with hub dynamo
Instead of conventional battery-powered lights, the TR.2825 features a powerful AXA lighting system with a Shimano Nexus hub dynamo. This gives you reliable lighting on every ride, with no need to change batteries.
Low-maintenance V-brakes
The fitted V-brakes impress with easy maintenance and reliable braking performance for everyday use. They provide safe control in both dry and wet conditions.
Practical everyday equipment
SKS fenders reliably protect you from rain and dirt. The pre-installed Racktime ECO 2.0 rack makes it easy to attach panniers or bicycle baskets, making this trekking bike especially practical for everyday use.
Environmentally friendly Schwalbe tires
Schwalbe Road Cruiser tires offer good grip, comfortable riding, and reliable puncture protection. The tread is made partly from renewable and recycled materials.
Subtle & modern design
The simple gray design looks both modern and understated. This makes the bicycle ideal for everyday use in the city and on tours.
