Bike Bottle Cages & Cycling Water Bottles — Hydration That Keeps Up With You

Hydration is one of the simplest performance gains available to any cyclist. Staying fuelled and hydrated on the bike — whether you're grinding a long gravel route, commuting on your e-bike, or pushing hard on a trail — keeps your power output consistent, your focus sharp, and your legs turning longer. The right bottle cage and bottle setup makes hydration effortless: always within reach, always secure, never in the way.

This collection covers everything you need: lightweight alloy and composite bottle cages from the B2BF range, durable cycling water bottles from SKS and Topeak, and combination cage-and-bag solutions for riders who want to carry more on longer adventures.

B2BF Alloy Bottle Cage

A durable alloy cage built for everyday riding and all-weather conditions. Robust enough for trail and commuter use, light enough to not notice it's there. A solid choice for MTB and e-bike riders who prioritise durability.

Cycling Water Bottles — Built for the Ride

SKS Bottles — Mountain 750ml, Road 750ml & Mountain 500ml

Hydration Tips for Cyclists

Drink before you're thirsty — thirst is a late indicator of dehydration; aim to sip every 15–20 minutes on rides over an hour
750ml for longer rides — on rides over 90 minutes or in hot conditions, a larger bottle reduces the need to stop and refill
Two cages for big days — most frames have two bottle cage mounts; use both on long gravel rides, bikepacking trips, or hot-weather rides
Clean your bottles regularly — cycling bottles need regular washing to prevent mould and bacteria build-up, especially in warm weather

Frequently Asked Questions

What size bottle cage do I need?

Most cycling water bottles follow a standard diameter (74mm), so the majority of cages are compatible with standard bottles. If you're using an oversized bottle (e.g., 800ml+) or a non-standard shape, check the cage's compatibility before ordering. All B2BF cages in this collection are compatible with standard 500ml and 750ml cycling bottles.

How do I fit a bottle cage to my bike?

Bottle cages attach to threaded bosses on your frame using two M5 bolts (usually 3mm or 4mm hex key). Most frames have two sets of bosses — one on the down tube and one on the seat tube. Simply align the cage, insert the bolts, and tighten firmly. Avoid overtightening on carbon frames.

Can I use a bottle cage on a fat bike or e-bike?

Yes — as long as your frame has standard bottle cage bosses, any cage in this collection will fit. Most Silverback e-bikes and MTBs include at least one set of bottle cage mounts. Check your specific frame's spec sheet if you're unsure.

How much water should I carry on a bike ride?

For rides under an hour, a 500ml bottle is usually sufficient. For rides of 1–2 hours, carry 750ml–1 litre. For longer rides, plan refill stops or use a hydration pack in addition to your bottle cages. In hot weather or at high intensity, increase your intake accordingly — aim for 500–750ml per hour of riding.

Are cycling water bottles dishwasher safe?

Most cycling bottles — including the SKS and Topeak bottles in this collection — are dishwasher safe on the top rack. Always check the individual product for specific care instructions. Regular cleaning after every ride is recommended to prevent bacteria and odour build-up.
