When Dahon designed the Mariner D7, the bike was built to target boaters who would use it for in-shore rides. However, the bike manages to broaden the scope and becomes the best-selling folding bike in the North America for years.
Once I tested the bike, I was not surprised with the success at all.

Dahon did a terrible job of taking press images for the Mariner D7. The bike doesn’t look pure white as you can see on Dahon’s website or Amazon’s listing. It actually has a brushed aluminum finish which is said to be rust-resistant. Notice that the The bike really looks much sleeker and more beautiful than I expected. Another advantage is the inclusion of a rear rack with luggage strap and fenders, so you don’t have to spend more for those accessories.
With regard to portability, the Mariner D7 is not the best but absolutely above average. Specifically, it can be folded compactly and it weighs just 26 lbs. I don’t really like the plastic Snap Lok clip system because it could be broken easily, I had another Dahon bike with the same clip system and it was broken out of the box. However, it does a good job of securing the two wheels when you fold the bike.
More importantly, the bike is very durable. I’ve had the bike for more than a year and it follows me on many journeys. It was placed inside my car trunk and checked onto an airplane on my trip to Asia. I rode the Mariner D7 on small and uneven roads with a lot of potholes in Hanoi. The bike is built to last and I’ve never had to fix it.
The Dahon Neos derailleur has a compact design and good performance. The shifting is not really smooth and you can’t have the same performance of high-end 7-speed Shimano derailleurs. However, it is good enough for most urban commuters.
