== Introduction ==
The Java Neo 3 Trifold 16" was first available in November 2025. It is a tri-fold bike that features a coaxial bottom bracket, internal cabling, hydraulic disk brakes, 6061-T1 aluminium frame, integrated headset, Shimano Sora rear derailleur, Altus shifters and 349 wheelset. It weighs approximately 9.9kg and was initially available for RMB 3000 / S$699.

In December 2025 the 20" version was announced with a weight of 10.6kg for RMB 3300, together with several colour options for the 16" and a full carbon variant of the 16". The Singapore version comes equipped standard with a carbon fork for S$799. An electronic shifting 12-speed version for the 16" equipped with the Wheeltop EDS Ox was also made available. A full carbon 20" electronic shifting version will be available in the future with no firm ETA yet.

== Updates ==
Newer versions of the 16" feature some changes over the earlier production models.

Front brake hoses are now longer.

Pedal QR can only be released at a specific rotation to prevent accidental release.

The front frame tube has a segment opening instead of round.

== Known Issues ==

=== '''Rolling interference''' ===
In some cases while rolling the bike when folded, the front wheel may touch the crank arm causing it to rotate and eventually interfering with the roll. To mitigate this issue, fold the bike in the lowest gear (largest sprocket). Installing a 3rd party hook extender may also help reduce interference.

=== '''Hook abrasion''' ===
The hook may cause scratches on the rear triangle when folded. To mitigate this issue, install a protector where the hook engages the rear triangle.

=== '''Brake hose length''' ===
When installing a higher rise handlebar, the front brake hose may be too short causing problems when folded. The brake hose will have to be replaced or lengthened. This issue was fixed in subsequent revisions (sometimes known as V2) of the bike.

=== '''Suspension block clearance''' ===
The suspension block may touch the ground when rolling folded if the bike is tilted backwards.

Suspension Block

Hxkenneth:

Material: Elastomer

Weight:

The Brompton G-Line / T-Line suspension blocks commonly have a mounting point with a diameter of 11mm to match those bikes. This will cause a poorly fitting suspension block when used on the JN3. Use a JN3 specific suspension block or modify those blocks to fit.

In December 2025 the 20" version was announced with a weight of 10.6kg (launch price S$799 in Singapore), together with several colour options for the 16" and a full carbon variant of the 16". A electronic shifting 12-speed version was also made available.

== Variants ==
Newer versions of the bike feature some changes over the earlier production models.

Front brake hoses are now longer.

Pedal QR can only be released at a specific rotation to prevent accidental release.

The front frame tube has a segment opening instead of round.

== Known Issues ==
'''Wheel & crank arm interference when rolling.''' In some cases while rolling the bike when folded, the front wheel may touch the crank arm causing it to rotate and eventually interfering with the roll. To mitigate this issue, fold the bike in the lowest gear (largest sprocket). Installing a 3rd party hook extender may also help reduce interference.

'''Hook scratching rear triangle.''' The hook may cause scratches on the rear triangle when folded. To mitigate this issue, install a protector where the hook engages the rear triangle.

'''Brake hose too short.''' When installing a higher rise handlebar, the front brake hose may be too short causing problems when folded. The brake hose will have to be replaced or lengthened. This issue was fixed in subsequent revisions (sometimes known as V2) of the bike.
