Dahon K3 Plus 16 inch(305) Folding Bike(kaa693) 2nd gen V2 Deltec Cable

The Dahon K3 Plus (KAA693, 305 wheel, 2nd gen V2 with DelTec) is a 16-inch, 9-speed disc-brake folding bike built to ride like a full-size commuter while still packing down small. At 9.8kg with a 100kg load limit, it sits between the ultra-light Dahon K3 and the bigger-wheeled Speed P8 among the Dahon folding bikes compared on this page.

Key Facts

• Category: 16-inch (305) folding bike, 9-speed, disc brake
• Brand: Dahon (DAHON, founded in the USA in 1982, main production now in Shenzhen, China)
• Standout feature: 2nd generation inner-folding head tube — folded width is reduced by 70mm versus the 1st generation, and this version is fitted with Dahon's DelTec frame tension cable, which the brand states increases frame stiffness by around 15%
• Key numbers: max load 100kg, recommended rider height 150-180cm, weight 9.8kg
• Best for: riders who want disc-brake stopping power and a wider gear range than the K3, without stepping up to the larger 20-inch Speed P8

The Problem It Solves

Many entry folding bikes feel underpowered on hills or in the rain because they rely on rim brakes and a narrow gear range. The K3 Plus adds a 9-speed drivetrain and disc brakes on a 16-inch wheel, so you get more confident braking and easier climbing while the bike still folds small enough for a lift lobby, MTR carriage or car boot.

Who It Suits

The K3 Plus suits riders 150-180cm tall, up to 100kg, who want a folding bike that can handle city hills, wet weather braking and daily commuting distances better than an entry-level 3-speed model. If you mainly need the lightest possible bike for very short, flat trips, the Dahon K3 14 inch 3-Speed Folding Bike is lighter. If you want even larger wheels for a smoother, faster ride, see the Dahon Speed P8 20inch 8 speed Folding Bike below.

2nd generation inner-folding head tube

The redesigned head tube folds inward and telescopes to adjust handlebar height, cutting 70mm off the folded width compared with the 1st generation K3 Plus — easier to carry through doorways and store in tight spaces.

9-speed drivetrain with disc brakes

Nine gears give a wider range for hills than a typical entry folding bike, and disc brakes keep stopping power consistent in Hong Kong's wet, humid weather compared with rim brakes.

Mounting points for accessories

The 2nd generation adds extra rack and fender mounting holes, plus three mounting holes at the front for a basket or bag — practical for grocery runs and commuting. Note that, like the smaller K3, the kickstand itself is not included and needs to be bought separately.

DelTec frame tension cable

This 2nd-gen V2 version is fitted with Dahon's DelTec — a tension cable running beneath the frame that connects the head tube and down tube to form a triangulated structure. Dahon states this increases frame stiffness by around 15% and reduces stress on the folding joint.

Which one fits your needs:

• Like a clean, internally routed look: Dahon K9x 16inch(305) Folding Bike - Japan Version — also on 305 wheels, but with cables routed inside the frame rather than along the DelTec cable, a one-piece inward-folding handlepost at a fixed height (not telescopic), plus MKS one-sided quick-release pedals and Tektro mechanical disc brakes as standard.
• Want larger 349 wheels from the factory: Dahon K3 Plus 349 16 inch Folding Bike - KAA693 — the 349 version of this bike, 10.44kg (Dahon official), folds to 72 × 39 × 63cm; the same spec also comes with a flat-welded, smoother-looking frame as the Dahon K3 Plus 16 inch(349) Folding Bike(KAA693) Flat Welding Version.
• Want 349 wheels on a K9 frame with DelTec cable: Dahon K9 16 inch 349 Folding Bike with Deltec Cable (KAA693) - International version — Dahon custom 9-speed with disc brakes, 10.4kg (Dahon official), height-adjustable handlepost.
• Ride lots of hills and want Shimano shifting with hydraulic discs: Dahon K9 16 inch 349 folding bike (KAA693) - Hong Kong Edition — Shimano Sora 9-speed (11–32T), Tektro hydraulic disc brakes, about 10.57kg (Dahon official).
• Light weight for short, flat trips matters most: Dahon K3 14 inch 3-Speed Folding Bike KAA433 — 14", 3-speed, V-brakes, 7.9kg without pedals, 75kg max load.

Jollymap's Advice

If your commute includes hills, wet-weather braking or grocery runs, the K3 Plus's disc brakes and wider gear range make it a more complete daily bike than the K3.

FAQ

What is the maximum load the Dahon K3 Plus can carry?

100kg. Dahon recommends this model for riders between 150-180cm tall.

What's the difference between the K3 Plus 305 and K3 Plus 349?

Both use the KAA693 frame with a 9-speed disc drivetrain, but the 349 version (Dahon K3 Plus 349 16 inch Folding Bike) uses a larger wheel bead-seat diameter and weighs slightly more (about 10.44kg per Dahon HK, the same official weight as the flat-welded version). Dahon has not published a folded size for the 305 version reviewed on this page, so we can't compare folded dimensions directly. Jollymap's current listing here is the 305 wheel version.

How much does the Dahon K3 Plus weigh?

9.8kg, according to Dahon's official specifications.

How is the K3 Plus different from the standard Dahon K3?

The Dahon K3 has smaller 14-inch wheels, 3 speeds and V-brakes at 7.9kg with a 75kg load limit. The K3 Plus steps up to 16-inch wheels, 9 speeds and disc brakes at 9.8kg with a 100kg load limit — better suited to hills, longer commutes and heavier riders.

How does the K3 Plus compare with Dahon's K9 series?

Jollymap also carries the Dahon K9x 16inch(305) Folding Bike and the Dahon K9 16 inch 349 Folding Bike with Deltec Cable if you'd like to compare with the K3 Plus. Message us before ordering and we can help you work through the differences.

What does "DelTec" mean on this model?

DelTec is a tension cable fitted beneath the frame, connecting the head tube and down tube to form a triangulated structure. Dahon states this increases frame stiffness by around 15% and reduces stress on the folding joint — it is not related to gear or brake cable routing.

Does the K3 Plus come with a kickstand and fenders?

No. Like the smaller Dahon K3, the kickstand is not included and needs to be bought separately. The 2nd generation does add extra mounting holes for a rack, fenders and a front basket or bag, making it easier to fit these accessories later.
