How to choose bike panniers

Yes, most panniers hook onto a rear rack, which takes the weight instead of your frame. If your bike has no rack, check whether it has mounting points near the rear axle and seat stays. Seat post racks suit some bikes without mounts, though they usually carry less.

A single pannier suits a light load like a laptop and lunch, and it is easy to carry into the office. Double panniers sit over the rack on both sides, which balances the weight and suits shopping or touring. If you often ride loaded, a double set feels steadier on the road.

Some are fully waterproof and some are only water resistant, so check each bag's description. Roll-top waterproof panniers are the safest choice for laptops, clothes and long wet rides. For standard bags, a rain cover adds extra protection in a shower.

It depends on both the bags and the rack, and each lists its own limit. Stay within the lower of the two, and remember that a heavily loaded bike takes longer to stop. Spread the load evenly and do a test ride before a big trip.

Most hybrid, city, touring and many gravel bikes can take a rear rack and panniers. Carbon frames, full-suspension mountain bikes and some road bikes may not have rack mounts, so check your bike's details first. If you are unsure, ask our team in store.
