Dahon Mariner D8 — 20" Folding Bike | Cyan 40th Anniversary
One of the world's most popular folding bicycles, the Dahon Mariner D8 was originally engineered for boaters and mariners — and that heritage shows. Built with rust-resistant, marine-grade components designed to thrive in high-moisture coastal environments, it's equally at home tucked into a caravan locker, stowed on a boat deck, or folded under your desk after the morning commute. Full-sized performance. Compact, go-anywhere convenience.
Who Is It For?
Best for leisure travel, boat and marine use, caravan holidays, and daily multi-modal commuting. One-size-fits-all frame adjusts for rider heights from 145–190cm (4'9"–6'3") with a maximum rider weight of 105kg.
Shimano 8-Speed Drivetrain
A premium Shimano 8-speed rear derailleur gives you an expanded gear range compared to standard folding city bikes. Take on steep coastal inclines, canal towpaths, and urban streets with crisp, effortless shifting every time.
Ultra-Fast 15-Second Fold
Dahon's patented Lattice Forged Hinge with ViseGrip technology lets the Mariner D8 fold down to just 65 × 28 × 80cm in under 15 seconds. It handles like a rigid, premium bike when open — and packs away like a compact suitcase when closed.
Rust-Resistant Marine Heritage
The lightweight Dalloy Sonus aluminium frame and corrosion-resistant hardware are built to withstand salt air and rain. Whether you're riding coastal paths or commuting through wet British winters, the Mariner D8 is built to last.
All-Weather Ready, Out of the Box
Comes fully equipped with an integrated alloy rear luggage rack for panniers and full-wrap mudguards to keep you dry. Rolling on agile 20" puncture-resistant tyres, with Dahon Ergo Comfort grips and an adjustable telescope handlebar for a perfectly dialled riding position.
