What Problem Does It Solve?
If you fold your bike several times a day for the MTR, the folding steps and the folded size both matter. The QIX D3's vertical folding lets you roll the bike straight into folded mode, and it folds to just 60 x 26 x 67 cm, only 26 cm wide, so it is easy to keep at the office or in a corner at home.
Who Is It For?
The QIX D3 suits short-distance commuters who fold the bike onto the MTR or into the office every day, and riders with limited space who want a narrow folded package. The included rack and full fenders also help on wet days or when carrying small loads.
It is not recommended for riders over 85 kg (the official maximum), or for routes with many hills that need a wider gear range (it has only 3 speeds). These riders may prefer the 9- or 6-speed models below.
Vertical folding: roll it and it is folded
Dahon says the QIX D3's vertical folding technology lets the bike be rolled directly into folded mode, quickly and easily. The Qix Arc frame uses Dalloy aluminium tubing with a flush vertical hinge and forged BB struts. See Dahon's official Qix folding video below for how it folds.
Custom Dahon 3-speed and front/rear brakes
The drivetrain uses a 46T forged aluminium chainring with guard, a custom Dahon 3-speed rear derailleur and trigger shifter, and a 9/11/13T cassette, with a KMC RustBuster all-weather chain. Braking is a forged aluminium dual-pivot caliper at the front and a custom Dahon V-brake at the rear.
Rack and full fenders included
Dahon's specification lists an aluminium rack and full-wrap fenders, plus Dahon folding pedals; a kickstand is not included.

Jollymap Recommends
The QIX D3's strengths are its narrow fold and simple 3-speed setup, best for riders who fold often and ride short distances, for example from home to the MTR station before folding to board. If your route has more hills, or you are close to the 85 kg limit, choose a model with more gears and a higher load rating. Not sure it suits you? Before ordering, chat with us or message our Facebook page with your height, weight and usual route.
