Our take on the Dahon Mariner D8 II Folding Bike

The Mariner D8 II is Dahon's aluminum 20-inch folding bike with a Shimano 8-speed drivetrain and a corrosion-resistant finish aimed at coastal and humid climates. It folds in three steps to roughly 33 x 14 x 26 inches and weighs about 28 pounds, so it fits in car trunks, boat cabins and small apartments. The 52T chainring with an 11-32T cassette gives a wide enough range for city streets and moderate slopes, and Tektro brakes and CST 20 x 1.5 tires cover everyday paved riding. It suits commuters and travelers who want a compact, rust-resistant folder more than a fast or lightweight one; rivals like the Brompton fold smaller and the Tern Link rides stiffer, but the Mariner leans on salt-air durability and simple 8-speed gearing.

About the Dahon Mariner D8 II Folding Bike

The Dahon Mariner D8 II is a folding bike with an aluminum frame, 20-inch wheels and Shimano 8-speed gearing. It weighs 27.9 pounds. The folding design makes it easier to store in apartments, vehicles, boats and other limited spaces.

The drivetrain pairs a 52T chainring with an 11T to 32T cassette. Tektro brakes handle stopping, and CST 20 x 1.5 tires run on a DAHON wheelset. The bike folds in three main steps, using a reinforced frame hinge and a patented handlepost design. An adjustable saddle and an extended aluminum seatpost fit a range of rider heights.

The aluminum frame uses coated components intended to resist corrosion in humid and high-salt environments. A standard MIK rear rack accepts compatible cargo solutions. Folding pedals and integrated fenders are included.

Questions and answers

Is the Dahon Mariner D8 II good for commuting?
Yes for mixed rides and transit, thanks to the three-step fold and stable 20-inch wheels. It is not the lightest folder, so stairs and long carries are the weak point.
How does it compare with the Brompton?
The Brompton folds smaller and is lighter, but costs far more and uses 16-inch wheels. The Mariner gives you a more stable ride and salt-air protection at a lower tier of the market.
Does it fit tall riders?
Dahon specifies an extended aluminum seatpost and adjustable saddle for a broad height range. Very tall riders should check the maximum seatpost extension before buying.
Can it handle hills?
The 52T chainring and 11-32T cassette cover moderate slopes. Long, steep climbs will feel harder than on a bike with a wider-range cassette or triple chainring.
Is it good for coastal or boat use?
That is its main selling point: the aluminum frame and coated components are designed to resist corrosion in humid and high-salt environments.
What comes in the box?
The bike ships assembled and folded, with the drivetrain and brakes fitted. Check the listing for whether a pump, tool kit or carry bag is included.
