Why You'll Love the Java NEO 20":

• Exceptional Stability & Comfort: Unlike many compact bikes, the Java NEO features a premium Carbon Fiber Fork. This significantly reduces overall weight while absorbing road vibrations, giving you a remarkably smooth and stable riding experience even on bumpy city streets.
• Lightweight & Portable: Built with a durable yet lightweight Aluminum Alloy frame, the entire bike weighs approximately 10.5kg, making it easier to lift, carry, and transport.
• Smooth & Reliable Shifting: Equipped with the Shimano CUES 9-Speed transmission system and an 11-40T cassette. Whether you're cruising on flat paths or tackling steep inclines, you'll always find the right gear.
• Uncompromised Safety: Upgraded with Hydraulic Disc Brakes, delivering powerful, responsive, and reliable stopping power in all weather conditions.
• Incredible Value: Combining carbon fiber components, hydraulic brakes, and genuine Shimano gears at this price point makes the Java NEO one of the most cost-effective folding bikes on the market.

Who it's for

• Taller riders or those who want a steadier ride: the 20" wheelset rolls over rough surfaces more confidently, with a taller handlebar (about 100cm) than the 16"
• Riders who want a carbon fork without electronic shifting: mechanical shifting is simpler and cheaper to maintain
• Daily commuters and weekend cycle-track riders: 9-speed is enough for city flats and most inclines
• Less ideal for: riders who just want the smallest possible folded size — see the Java NEO 9S 16" 349 instead

If an aluminium fork is fine for you, the Java NEO 20" 9s Folding Bike is also a 20" Shimano CUES 9-speed (11–40T); if you like the polished silver finish, see the Java NEO 20" Chrome Limited Edition (12-speed electronic or 9-speed mechanical).

FAQ

What's the difference between the Java NEO 20" carbon fork version and the 16" 349?

The main differences are wheel size, fork material and handlebar height. The 20" (406) rolls over rough surfaces more confidently and has a taller handlebar (about 100cm vs. about 92cm on the 16"), suiting taller riders or those who want a steadier ride; the 16" 349 folds to a smaller footprint, better for frequent MTR commuting. This page's 20" version comes with a carbon fork as standard, while the standard 16" uses an aluminium fork — if you want a 16" with a carbon fork, see the Java NEO 9S 16" (Carbon Fork version). For a detailed comparison, read Jollymap's Java Neo 20: What to Know Before You Buy (in Chinese).

What are the benefits of a carbon fork — is it durable, could it crack?

A carbon fork is lighter than an aluminium one and dampens vibration better, so long rides or rough pavement feel less harsh on your hands. Under normal use (no crashes or impacts) it's just as durable as a metal fork; when servicing, keep torque within the manufacturer's limits, and check for cracks before continuing to ride if the fork has taken a hard knock.

How much does the complete bike weigh with pedals?

About 10.5 kg.

Is 9-speed enough? Can I upgrade to electronic shifting?

The 9-speed (11–40T) drivetrain covers Hong Kong's everyday roads and most inclines. If you'd like electronic shifting, the Java NEO 20" Electric Shift 12-Speed Folding Bike shares the same frame and fork platform, making it a straightforward upgrade path.

Can I take it onto the bus or MTR when folded?

MTR requires that the combined length, width and height of hand-carried items does not exceed 170cm, with no single side over 130cm. The Java NEO 20"'s official folded dimensions are about 73 × 32 × 64 cm (excluding pedals, a total of about 169cm) — close to the limit; with pedals it is about 41cm wide (a total of about 178cm), which is over the limit, so remove the quick-release pedal before boarding. For buses, under the Public Bus Services Regulations (Cap. 230A) Section 14, the free baggage allowance is capped at 5kg and 0.1 cubic metres, which the whole bike typically exceeds — whether it's allowed on board depends on the bus company and driver. It also has built-in easy wheels for rolling it along once folded.

How should I look after it in Hong Kong's humid weather?

The hydraulic disc brakes and aluminium frame resist corrosion reasonably well, but wipe down the frame and chain after riding in the rain and lubricate the chain regularly to prevent rust from affecting shifting.

Is the Java NEO 20" 9-Speed Carbon Fork suitable for a first-time folding bike rider?

Yes. The 9-speed drivetrain and hydraulic disc brakes are intuitive to operate, making this a good first 20" folding bike.
