Topeak Modula Java Bottle Cage - Adjustable Bike Cup & Tumbler Holder, Black, Telescoping Height

The Topeak Modula Java Bottle Cage is an adjustable bike-mounted holder that secures coffee cups, travel tumblers, and small Bluetooth speakers while you ride.

Lightweight and engineered for urban and recreational cyclists, this cage uses engineering-grade polymer and rubber to hold a wide range of container shapes. Its telescoping height and expandable diameter let you fine-tune the fit for popular cups and tumblers, while a compact footprint keeps your frame uncluttered. Installation is simple on standard bottle cage bosses, making it a practical add-on for commuters, e-bike users, or weekend riders who want on-the-go convenience.

Will this fit my coffee cup or travel tumbler?

Yes — the Modula Java Cage is built to adapt to many common drinking vessels. Adjust both the upper and lower circumference to cradle your container securely and change the height to match taller tumblers.

• Upper diameter range: 75–90 mm to accept wider lids and cups.
• Lower diameter range: 60–78 mm for a snug base grip.
• Height adjustment: accommodates 175–240 mm tall containers.

How stable is it on bumpy roads or during commutes?

The Modula Java Cage combines a rigid polymer frame with rubber contact points to reduce movement and absorb vibrations. While no accessory can eliminate all motion, the combination of adjustable sizing and vibration-damping materials helps keep items in place on typical urban surfaces.

• Engineering-grade polymer frame resists flex under load.
• Rubber interfaces cushion against road vibration.
• Customizable grip reduces wobble from mismatched cup shapes.

How easy is it to mount and adjust on my bike?

Mounting is straightforward: the cage attaches to standard bottle cage bosses with common hardware, and adjustments require no special tools beyond basic hex keys. Quick radial and height adjustments let you dial in a secure fit before hitting the road.

• Installs on standard frame bosses using included or common bolts.
• Tool-accessible adjustments for diameter and height.
• Compact design keeps cables and panniers clear.

Can it carry non-drink items like a portable speaker?

Yes — the cage is versatile enough to hold small portable speakers and similar cylindrical items that match its adjustable dimensions. Make sure the speaker sits firmly within the diameter and height ranges to minimize movement.

• Accommodates small Bluetooth speakers within size parameters.
• Rubber contact points protect finishes and reduce slippage.
• Low weight (approx. 4.2 oz) avoids adding unnecessary bulk.

Who is this for? The Topeak Modula Java Cage is aimed at cyclists who want a flexible, lightweight solution for carrying beverages or compact devices on short commutes, city rides, and weekend outings. It suits riders of road, commuter, folding, and electric bikes who value adjustability and a neat installation without sacrificing frame space. If you regularly bring coffee, a travel tumbler, or a small speaker along, this cage gives you a customizable hold that balances accessibility with secure mounting.
