7 Best Bike Accessories 2026

Every other accessory here helps you deal with something that has already happened. The Varia RTL515 tells you it’s about to: a rear-facing radar and tail light that watches the road behind for up to 153 yards and pushes an alert to a Garmin computer, a compatible watch, or your phone. After riding with it, it’s the one thing in this guide we won’t go without.

The light half is not an afterthought. Daylight visibility runs to a mile, and the flash gets more urgent as a vehicle closes — drivers notice it even when they haven’t noticed you. Pairing with an Edge computer is a one-time job, and the phone app supplies the same graphics with a tone and a vibration, which is enough for a bike with no computer on the bars.

Plan the battery around the mode you’ll actually use: six hours solid, eight in peloton, sixteen in day flash, and day flash is the setting that keeps the radar alive from breakfast to dinner. It is comfortably the most expensive thing in this guide, and the case for it is simple — the more traffic you share a road with, the more those warnings are worth.

The shackle looks small on the page, and it is: 7.76 by 5.02 inches on the outside leaves a modest mouth — fine around a frame and a Sheffield stand, possibly too tight around a fat lamp post. The five-foot cable is the answer. Loop the shackle through the frame and the post, run the cable through both wheels and a helmet, and the small opening stops mattering.

Steel is the argument. A 17 mm shackle and zinc alloy core make this the sort of hardware that sends a thief looking for an easier bike, and the key turns cleanly in the cylinder instead of grinding. Two keys ship in the box, which matters more than it sounds: one on the ring, one in the bag.

Where it lands for us is as a leave-it-on-the-bike lock for errands and commutes rather than a touring lock you carry all day. The bracket holds it against the frame, clear of your legs, and the whole package is the peace of mind you were actually shopping for.

This is the least expensive way here to get a phone onto the bars, and it doesn’t ride like a compromise. A silicone-wrapped cradle tightens onto the handlebar by hand — no tools, no bracket to bolt on — and it takes phones from 4.7 to 6.8 inches on bars from 0.6 to 1.57 inches, which covers most hybrids, road bikes and e-bikes.

Two things stood out in use. The corners wrap around the phone rather than clamping its edges, so a case doesn’t have to come off, and the grip held through broken tarmac and a gravel towpath without the phone creeping round. It also comes off the bars in one pull when you park. For the money, this is the mount we recommend first.

The commute is where a frame bag earns its keep: phone on top where the map is, keys and a multitool underneath, a snack in reach and nothing bulging in a jersey pocket. The ROCKBROS holds 1.6 liters in an 8.15 by 3.74 by 5-inch body that straps to the top tube with three Velcro straps and a front loop.

The top window takes phones under seven inches and stays responsive enough for map checks and answering a call at a light; it’s not a surface you’ll want to type on. Underneath, one main compartment swallows a mini pump, a spare tube, a wallet and a bar. Reflective piping and a double zip are the details that make it feel considered rather than cheap.

Fitting takes about five minutes with no tools. Ours shifted a little on washboard gravel in the first week; re-tensioning the straps and using the longer front loop sorted it, and it stayed put after that. Worth doing before you load it up rather than after.

Where it stops being the right bag is a fast road ride — this is a commuter and touring shape, not a race one. For getting to work with a phone you can see, a tube you don’t have to think about and pockets that stay empty, it’s the bag we point people to.

Twenty-seven grams, 1.7 cm thick, and small enough to sit between a bell and a grip without moving either. The Zewdov set puts a 250-lumen front light and a red rear on elastic straps, charges both from one split USB cable in about 1.5 hours, and at that size we expected a toy. We got a genuinely useful urban set instead.

Light quality is the surprise. Four front modes plus steady and flash at the back cover lit streets, dusk and the grey hour before rain, and IP65 means road spray and a proper downpour are both fine. 250 lumens is a being-seen output rather than a seeing output — on an unlit trail you want a real headlight, and this isn’t one.

A one-year warranty stands behind the pair, which is why it stays an easy recommendation at this level. Charge both before a night ride and treat the rear as your fallback; as a commuter set that lives on the bars, it does the job we want.

Insulation and squeezability usually fight each other — foam and a double wall keep water cold and turn the bottle rigid. The Podium Chill gets the balance right: a 21-ounce TruTaste body you can still crush one-handed, wrapped in a double wall, with a high-flow cap that seals itself between sips so it doesn’t dribble down your stem.

It drops into a standard cage, including the tight mountain-bike cages that reject fatter bottles, and at 2.87 inches across it doesn’t foul the frame. The wide mouth and a valve that comes apart for cleaning make it easy to look after properly, which is more than you can say for most squeeze bottles.

Where it earns its place is the two-hour ride in warm weather, not a desert expedition. Water stays properly cold for the first hour and pleasantly cool after that, and the squeeze means you drink without breaking rhythm. For everything short of a heatwave century, it’s the bottle we reach for.
