Best bike computers for trekking bikes in 2026

For a trekking bike, the focus is carrying capacity and long-distance comfort. A pair of waterproof rear panniers like the Ortlieb Back-Roller Classic is essential — they survive years of Dutch rain and can carry an entire holiday's worth of gear. For heavier trips you can add Ortlieb Front-Rollers or a handlebar bag (Ortlieb Ultimate Six) for snacks, maps and phone. A solid ART-2 lock such as the ABUS Bordo 6000 is enough for parking at a guesthouse or terrace. Always carry a multitool (Topeak Hexus), a spare tube, a puncture kit and a mini pump. A dynamo headlight like the Busch & Müller IQ-X Lumotec pairs perfectly with a Shimano or SON hub dynamo and always provides light without batteries. A bike computer or GPS like the Garmin Edge Explore helps with junction navigation and LF routes. A comfortable saddle (Brooks B17, Selle SMP TRK) saves weeks of discomfort on multi-day rides. A rain suit (jacket plus trousers) is a Dutch essential. Finally: chain lube for the road and a pair of gloves to fight fatigue.
