Revolutionize your hydration with the Fidlock TWIST bottle 550 + bike base system, a radical innovation that frees your frame from the traditional bottle cage thanks to patented magneto-mechanical technology. This complete kit combines an ergonomic 550 ml bottle with a minimalist 16 g mount, offering instant magnetic attachment and release with a simple twist — it has never been so easy and safe to hydrate while riding, even on the most compact frames.

Technical overview of the TWIST 550 system

The Fidlock TWIST 550 lives up to its name: with its compact and volumetric design, this bottle occupies the same footprint as a 450 ml model while offering 100 ml of additional capacity for demanding rides. Weighing only 112 g (connector included) for 550 ml, it delivers an excellent weight-to-capacity ratio. The patented magneto-mechanical system combines powerful neodymium magnets and mechanical locking: the bottle clips automatically on contact with the base and only releases with a clockwise rotation. The ultra-light base (16 g) attaches to standard bottle cage holes, transforming any frame into an intuitive hydration station.

Technical highlights

• Patented SNAP & TWIST technology: Neodymium magnets attract, center and engage the bottle magnetically on the base. Mechanical locking ensures absolute hold, even under stress. A simple clockwise "TWIST" releases the bottle with one hand.
• Self-sealing high-flow valve: Self-sealing membrane ensuring generous water flow without leaks, even when lying flat. The removable dust cap protects the spout during off-road rides or on the down tube.
• Compact and ergonomic design: Optimized volumetric design for narrow frames where a classic bottle cage won't fit. Ergonomic shape with textured grip zones for intuitive handling. Wide opening facilitating filling and cleaning.
• Premium BPA/BPS-free materials: Bottle made of polyethylene and thermoplastic rubber, food-safe and durable. Base and connector in technical polyamide with magnetic inserts and stainless steel. Dishwasher safe up to 50 °C (remove connector).
• Modular scalable system: The TWIST system is fully modular — the connector can be removed from a worn bottle and attached to a new bottle. Compatible with the entire TWIST ecosystem (alternative bases, accessories).

Installation and compatibility

The kit includes 1 TWIST 550 ml bottle with pre-assembled magnetic connector, 1 bike base and 2 stainless steel screws for mounting on standard bottle cage holes (64 mm spacing). Installation takes just seconds: screw the base onto the frame, bring the bottle close — the magnets do the rest. The system is compatible with all TWIST bases (bike base, uni base, tex base multi) and all TWIST connectors, allowing you to customize your setup according to your needs (main frame, seat tube, down tube, bikepacking fork…).

Use and maintenance

The bottle is designed for still water up to 70 °C — any use with carbonated drinks, acidic juices or non-compliant liquids is the user's responsibility. Easy cleaning by hand or dishwasher (up to 50 °C, without the magnetic connector). Always BPA-free and BPS-free, compliant with food contact standards. The self-sealing membrane guarantees leak-proof performance, even when the bottle is inverted. Over time, if the bottle ages, the magnetic connector easily detaches (with a coin) to be reused on a replacement bottle, reducing waste.

Why choose the TWIST 550?

• Radical space savings: Ideal for XS/S frames, full-suspension frames, compact gravel bikes, e-bikes with integrated batteries — anywhere a classic bottle cage doesn't fit.
• Safety while riding: Intuitive one-handed operation without letting go of the handlebars. The magnetic system eliminates fumbling, and mechanical locking prevents accidental ejection on rough trails.
• Sleek aesthetics: Minimalist design that enhances your frame. Quality finish, discreet integration, high-tech feel.
• Maximum versatility: Compatible with all TWIST products (bags, tools, VACUUM smartphone mounts…). One system for multiple uses.

Available variants

• Black variant: EAN 4251207407079 — classic black finish, sober and timeless design.
• Transparent/Smoke variant: Translucent smoke finish, allows viewing liquid level. Available in the same 550 ml + bike base format.
• Clear variant: Full transparent finish for maximum visual control of water level.
• FIDGUARD antibacterial variant: Version with integrated antibacterial treatment inhibiting bacterial growth in residual moisture. Ideal for intensive use and enhanced hygiene (reference AB-09743-P00002, Smoke-Antibacterial finish).
