A practical choice for anyone who needs a bottle cage on an e-bike or bicycle without conventional mounting bosses.
The ZEFAL GIZMO is a universal bottle-cage mounting system for adding a cage or compatible accessory where your bike has no threaded mounts—or where you simply need another mounting position. It can be fitted to the frame, fork, stem, handlebar or seatpost, making it particularly useful for e-bikes, commuter bikes, touring setups and frames with limited bottle-cage options.
Its adjustable clamps accommodate tubes from Ø15 to 75 mm. The integrated soft strap improves grip and helps protect the paintwork on tubes from Ø16–36 mm; for larger tubes, use transparent protective strips before installation. Tighten the supplied screws to the recommended 2 N·m torque, then check the mount is secure before riding.
In day-to-day use, accurate positioning and firm installation matter. Real-world testing found the design effective when correctly sized and not overloaded, while a more recent customer experience described it as simple to fit but capable of moving when subjected to force. For that reason, we recommend using it primarily for a bottle cage or light accessory rather than heavy loads, especially on a fork.
