Portable cycling tech preview

A preview of compact cycling devices from Garmin Knog Nix Biosensors H2O Audio and Fumpa shows on the go power hydration insight and data driven workouts.

Tiny pump and smart sensors redefine portable cycling tech

Road.cc previews a set of portable cycling gear that aims to shrink tech without shrinking capability. The lineup includes Fumpa’s nanoFumpa pump, Knog’s Oi Prima bell, Nix Hydration Biosensor, H2O Audio’s Zwift collaboration RIPT Ultra headphones, and Garmin HRM 600. Prices range from around £27.99 to £149.99 as listed in previews and product pages.

The nanoFumpa is described as the world’s smallest pump, measuring 2.2 x 1 x 1.8 inches and weighing 102 g. It can inflate a road or mountain bike tyre to about 90 psi in roughly 90 seconds and maxes out at 120 psi with replaceable batteries and seals. The Knog Prima bell keeps the familiar wrap around look but adds a redesigned hammer mechanism for a louder reliable chime and comes in two bar sizes for broad compatibility.

Nix Hydration Biosensor uses a disposable patch to read sweat biomarkers and provide real time guidance via a rechargeable pod connected to a mobile app. The system reports sweat rate electrolyte loss and composition with up to 36 hours of pod battery life and a kit that includes patches charging gear.

The RIPT Ultra headphones from H2O Audio and Zwift label target athletes who train nonstop. The over ear design offers sweat resistance, Bluetooth streaming, hands free calling and up to 50 hours of battery with a protective case included. Garmin’s HRM 600 is pitched as the premium chest strap replacing the HRM-Pro Plus. It transmits heart rate HRV data and when paired with a watch can deliver running dynamics plus direct data syncing to Garmin Connect. The strap is machine washable and water rated to 5 ATM with two size options.

The collection reflects a clear move toward small, data rich gear that doubles as everyday wear. Consumers gain more ways to monitor performance on the road while keeping gear light enough to carry in a pocket or a small bag. Prices span from accessible to premium, which could broaden appeal but also risks splitting the market between casual riders and metric focused athletes.

Highlights

As gear gets smaller, riders will rely more on field tests to prove real world value.
