Daily Commuters who cycle in all weather, including heavy rain
Long-Distance & Touring Cyclists needing large, reliable storage
Urban Riders carrying work, shopping, or travel essentials
Night Cyclists who value high visibility and safety after dark
Built with high-frequency seamless welding and a 100% polyester main fabric, this pannier creates a fully sealed waterproof barrier. Welded seams eliminate needle holes, while the taped, water-resistant zip prevents leaks—keeping your belongings dry even in heavy downpours.
With a practical 20-litre capacity, the bag offers ample space for daily commuting items, clothing, groceries, or travel gear. The interior layout allows organised storage, making everyday cycling more convenient and stress-free.
The roll-top design enhances waterproof performance while allowing flexible capacity adjustment. Roll it down for compact loads or expand it when carrying more on longer journeys.
Durable adjustable buckles provide a firm and stable attachment to the bike rack. The top hooks can be adjusted sideways to fit a wider range of racks, while the bottom fixing mount rotates 360° and slides laterally for precise positioning and reduced movement.
Designed for convenience, the pannier can be quickly mounted or removed. A built-in carry handle allows you to lift and go without hassle when off the bike.
More than just a bike bag—use the included adjustable shoulder strap to switch quickly between pannier and shoulder bag. Ideal for commuting, shopping, or travel when you need to carry it by hand.
The widened anti-slip shoulder strap adjusts from 80 cm to 136 cm, offering comfortable carrying and a secure fit for different body types.
The reflective version features an all-over high-visibility reflective surface. Under headlights or street lighting, the bag’s outline becomes clearly visible, significantly improving safety during night rides and low-light commuting.
