Moustache Mardi 27.4 FS - practical every day
Full-length mudguards, integrated lighting, and a sleek rear rack mean you’re ready for commuting, errands, and weekend trips straight out of the box.
The Light Luggage Carrier keeps the look clean and elegant while remaining highly functional. With QL3 mounting as standard, compatible panniers click neatly into place without bulky hooks, and removable studs mean you can still use traditional panniers when needed.
Everything is designed to look good, work properly, and last.
Easy, low-maintenance ownership
Thanks to its carbon belt drive and internal hub gears, this bike is refreshingly simple to live with. There’s no oily chain to clean, no derailleur to adjust, and far less wear over time.
The Nexus 5 hub allows you to change gear while stationary, making stop-start city riding effortless, while the belt runs quietly and cleanly in all weather.
Combined with Bosch reliability and Fully Charged’s trained workshop support, it’s a setup designed for long-term peace of mind.
