Dahon K3 14 inch 3-Speed Folding Bike KAA433

The Dahon K3 (KAA433) is a 14-inch, 3-speed aluminum folding bike built for short trips and tight storage spaces — Dahon describes it as a lightweight folding bike, weighing 7.9kg (without pedals) and folding down to just 68 x 31 x 65cm.

Key Facts

• Category: compact 14-inch folding bike, 3-speed
• Brand: Dahon (DAHON, founded in the USA in 1982, main production now in Shenzhen, China)
• Standout feature: 7.9kg without pedals — Dahon markets the K3 as a lightweight folding bike
• Key numbers: max load 75kg, recommended rider height 150-180cm, folded size 68 x 31 x 65cm (L x W x H)
• Best for: riders who want the smallest, lightest bike for short commutes, MTR/bus trips or storing in a small flat — not for long-distance or hilly rides

The Problem It Solves

Hong Kong flats and offices rarely have room for a full-size bike, and carrying one up stairs or onto a minibus is a hassle. The K3's 14-inch wheels and 3-speed drivetrain keep the whole bike small and light, so it folds fast and is easy to carry for the last stretch of a commute or a short errand.

Who It Suits

The K3 suits riders 150-180cm tall who mainly ride flat, short routes — to the MTR station, around the neighbourhood, or as a spare bike to keep in the car or office. It is not the right choice if you regularly climb hills or ride long distances: 3 speeds and 14-inch wheels give a shorter, less efficient stride than the 16-inch K3 Plus or 20-inch Speed P8 below. Riders outside the 75kg load limit or 150-180cm height range should consider a larger Dahon model instead.

Ultra-light aluminum frame

The full aluminum frame and 14-inch wheels bring the bike down to 7.9kg without pedals, so lifting it onto a rack, up a flight of stairs, or into a car boot takes far less effort than a standard bike.

3-speed drivetrain kept simple

A simple 3-speed drivetrain covers the flat, short routes the K3 is designed for without the extra weight and maintenance of a wider-range cassette — ideal for riders who want a "just get on and go" folding bike.

Compact fold for storage

Folded to 68 x 31 x 65cm, the K3 tucks under a desk, into a lift lobby, or beside a sofa without taking up floor space — useful in typical Hong Kong flat sizes.

Jollymap's Advice

If you mainly need a folding bike to bridge the last mile to public transport or to keep in a small flat, the K3's light weight is a real advantage. If your usual route has hills, or you want a bit more speed and stability, step up to the K3 Plus or Speed P8 above. Not sure which fits your height, storage space or usual route?

FAQ

How much does the Dahon K3 weigh?

7.9kg without pedals — Dahon markets it as a lightweight folding bike, easy to carry up stairs or lift onto a rack.

What is the maximum load and recommended rider height for the K3?

Max load is 75kg, and Dahon recommends it for riders between 150-180cm tall. If you are outside this range, or close to the load limit, consider the Dahon K3 Plus or Speed P8, which both carry up to 100-105kg.

How big is the K3 when folded?

68cm (L) x 31cm (W) x 65cm (H) according to Dahon's official spec sheet. Actual measurements can vary slightly depending on the measuring method used.

What's the difference between the Dahon K3 and K3 Plus?

The K3 has 14-inch wheels, 3 speeds and V-brakes at 7.9kg; the K3 Plus has larger 16-inch wheels, 9 speeds and disc brakes at 9.8kg with a higher 100kg load limit. The K3 Plus rides more like a full-size bike; the K3 is lighter and easier to carry.

Does the Dahon K3 come with a kickstand?

No. According to Dahon's spec sheet, the kickstand is not included on the K3 and needs to be bought separately if you want one.

Is 3-speed enough, or should I get a bike with more gears?

3-speed suits flat, short routes such as riding to the MTR station or around a housing estate. If your route includes hills or you want more range for longer rides, the 9-speed K3 Plus or 8-speed Speed P8 will be more comfortable.

How should I maintain a folding bike in Hong Kong's humid weather?

Wipe down the frame and chain after rides in wet weather, keep the folding joints lightly lubricated, and store the bike somewhere dry rather than outdoors. If it has been folded up unused for a long time, check the brakes, chain and folding joints yourself before riding again.
