Java NEO 9S 16 inch 349 9 Speeds Folding Bike (Carbon Fork version)

The Java NEO 9S 16-inch Carbon Fork version is a tri-fold folding bike with an aluminium frame and a carbon fork, running 16-inch 349 wheels, a 1x9 drivetrain and hydraulic disc brakes. Java quotes about 9.8 kg for the complete bike and a folded volume of about 0.12 m³. It shares its aluminium frame with the standard NEO 9S; the main upgrade is the carbon fork, which lightens the front end and filters out small road vibrations. It suits commuters who fold onto the MTR often but also want longer rides to feel smoother.

Key Facts

• Category: 16-inch (ETRTO 349) tri-fold folding bike, 9-speed, carbon fork version
• Brand: Java (Shenzhen ChuangXinWei Bicycle Co., mainland China), official model NEO-349ALF
• Standout feature: the standard NEO with a carbon fork for better vibration damping; the 16-inch carbon fork version usually comes with a 6 cm riser bar, slightly more upright than the 2 cm bar on the standard version
• Key numbers: about 9.8 kg (Java figure); folded 69 x 30.5 x 58 cm (about 0.12 m³); 50T chainring, 11–32T cassette, 165 mm cranks; hydraulic disc brakes
• Best for: riders who fold onto the MTR regularly, have limited space at home, and ride long enough that hand and wrist vibration matters

Why Choose the Carbon Fork Version?

Hong Kong streets are full of paving bricks, drain covers and speed bumps. An aluminium fork gives direct road feel, so vibration reaches your wrists easily; a carbon fork filters out the small, high-frequency buzz. In Jollymap's review, if you usually ride for more than an hour at a time, this upgrade noticeably reduces hand fatigue. The frame itself has a redesigned rear triangle whose folding pivot sits on the same centre as the bottom bracket, shortening the BB-to-rear-axle distance to 35 cm (about 41 cm on a typical Brompton-style trifold) for quicker take-off. The 107 cm wheelbase and roughly 26 cm BB height keep the centre of gravity low and the ride stable.

Who It Suits

• Good fit: commuters who fold in and out of the MTR, malls or offices; riders who need to store the bike in a hallway or under a desk; anyone who wants NEO portability with a more comfortable front end than the standard version.
• Maybe not: taller riders (for example over 180 cm) or those who cruise long distances; Jollymap's review suggests the 20-inch version (handlebar about 100 cm off the ground versus about 92 cm on the 16-inch), such as the Java NEO 20 inch 9 Speed Carbon Fork Folding Bike.
• Tighter budget: if you don't need the carbon fork, the Java NEO 9S 16 inch 349 9 Speeds Folding Bike (standard version, aluminium fork) uses the same frame.

Key Features

3-step fold with a neat, square package

The NEO uses a simple, intuitive fold and packs into a regular shape: Java quotes about 0.12 m³ (69 x 30.5 x 58 cm). The pedals are quick-release, so you can remove them for a car boot or storeroom.

Fold and roll, no lifting

Once folded, the bike rolls on its wheels and built-in easy wheel. Java says it can be pushed smoothly even without rack wheels, which helps inside MTR stations and malls. Push it forwards: pulling it backwards turns the cranks and a pedal can catch the wheel.

Carbon fork: stiff and vibration-damping

The carbon fork trims weight at the front and soaks up small road vibrations. It is the main difference from the standard version.

Shimano 1x9 drivetrain with hydraulic disc brakes

A single-chainring 9-speed setup is simple to use and needs less maintenance; the 16-inch version runs an 11–32T cassette for flat roads and ordinary climbs. Hydraulic disc brakes give a light, linear feel and stop reliably on wet roads, with compact flat-mount calipers for a clean look.

Semi-internal cable routing

The rear shift cable and brake hose run through the middle of the frame, and the front brake hose hides inside the stem, for a clean look. Servicing the routing later takes more work than on an externally routed bike.

Java NEO Range Compared

For the same aluminium frame and carbon fork with 12-speed electronic shifting and an 11–40T cassette, see the Java NEO 12s 16 inch 349 Electric Shift 12-Speed Folding Bike, or the same spec in a limited polished-silver finish, the Java NEO 16" Folding Bike Chrome Limited Edition. For a walk-through of the whole range, see Jollymap's article Java Neo folding bike family guide (in Chinese).

Jollymap's Advice

Before folding a NEO, shift into the lowest gear (largest cog) so the chain sits at the right tension and is less likely to drop; there is a reminder label on the handlebar. The stock saddle is on the firm side; for longer commutes consider the Air Seat 1 AFT Suspension Saddle. For easier parking, see the Mr TiParts Carbon Kickstand for Java Neo 16 inch; for luggage, the Mr TiParts Java Neo Rear Rack.

FAQ

What is the difference between the NEO 9S Carbon Fork version and the standard version?

The fork and the handlebar. The Carbon Fork version has a carbon fork, so the front end is lighter and absorbs vibration better, and the 16-inch carbon fork version usually has a 6 cm riser bar versus the standard version's 2 cm bar, giving a slightly more upright position. Both share the same aluminium frame, 349 wheels, 50T chainring, 11–32T cassette and hydraulic disc brakes. See the standard Java NEO 9S 16 inch 349 9 Speeds Folding Bike.

How much does the Java NEO 9S Carbon Fork version weigh?

Java quotes about 9.8 kg for the complete bike, without saying whether pedals are included. For reference, Jollymap weighed the aluminium-fork standard version at about 10.2 kg (10.16 kg) with pedals.

How big is it folded, and can I take it on the MTR or a bus?

Java's folded size is 69 x 30.5 x 58 cm (about 0.12 m³), about 157.5 cm in total. The MTR allows luggage up to 170 cm in total length, width and height, with no side over 130 cm, so this is within the limit; Java doesn't say whether pedals are included, and the quick-release pedals can be removed before boarding. On franchised buses, the Public Bus Services Regulations (Cap. 230A) section 14 only allows free carriage of items within 5 kg and 0.1 m³, which a whole bike exceeds, so it is up to the bus company and driver; minibuses make no guarantee either.

16-inch or 20-inch Java NEO: which should I choose?

Choose 16-inch if you fold onto the MTR often or have little storage space; choose 20-inch if you are tall (for example over 180 cm) or cruise long distances. The 20-inch uses 406 wheels and puts the handlebar about 100 cm off the ground (about 92 cm on the 16-inch), with a longer, steadier wheelbase, but it folds bigger. For a 20-inch carbon fork model, see the Java NEO 20 inch 9 Speed Carbon Fork Folding Bike (Shimano CUES 9-speed, 11–40T). Jollymap's article Java Neo 20 vs 16: what's different? (in Chinese) compares the two sizes in detail.

What rider height does the 16-inch NEO 9S suit?

Java has not published a recommended height. The 16-inch comes in one frame size, and Jollymap's review suggests taller riders (for example over 180 cm) consider the 20-inch version. If you're unsure, contact us with your height before ordering.

What should I watch out for when folding and rolling it?

Shift into the lowest gear (largest cog) before folding to reduce chain drops, and push the folded bike forwards: pulling it backwards turns the cranks and a pedal can catch the wheel or frame.

Can I fit a kickstand or rear rack to the NEO 9S Carbon Fork version?

Yes. Jollymap has the Java Neo 16-inch Mr TiParts Aluminum Kickstand and carbon kickstand, the Mr TiParts Java Neo Rear Rack and the Java Neo Easy Wheel Extension Bar. Contact us before ordering to confirm an accessory suits your batch.

Where can I buy the Java NEO 9S Carbon Fork version in Hong Kong?

Jollymap sells it online and in our shop, in White Red, Sakura White (Limited Edition), Titanium Red, Grey, Titanium and Matt Orange. Chat with us if you'd like to confirm colour or spec before ordering.
