Schwalbe Billy Bonkers 20” x 2.00 (50-406) Tanwall Tyre | Java Neo 20”

20 × 2.00 • ETRTO 50-406 • Tanwall Schwalbe Billy Bonkers 20” 406 for Java Neo & Folding Bikes A fast-rolling, distinctive 20-inch tanwall tyre with a wider 2.0-inch profile. For Java Neo 20” owners, we have developed a complete fitment solution that keeps folding and rolling functionality working properly. Java Neo 20” Compatible 20 × 2.00 50-406 ADDIX Compound Singapore Fitment Support Can Billy Bonkers 20” Be Fitted On A Java Neo? Yes. Schwalbe Billy Bonkers 20 × 2.00 (50-406) tyres can be fitted to Java Neo 20-inch bicycles, including aluminium, carbon-fork, full-carbon, J-AIR, ECO and earlier 20-inch versions. Important: It is not a simple tyre swap on a Java Neo 20”. The wider 2.0-inch tyre changes the available clearance when the bike is folded. A properly configured Java Neo Billy Bonkers setup requires supporting parts so the bicycle can continue to fold and roll correctly. What Is Required For A Java Neo Billy Bonkers Setup? We treat the tyre, folding clearance and rolling system as one complete setup rather than fitting the wider tyre alone. 1 Billy Bonkers 20 × 2.00 This listing is for one Schwalbe Billy Bonkers 20-inch 50-406 tyre. Select quantity 2 for a complete front-and-rear set. 2 20” × 2.0 Inner Tube The original Java Neo inner tube is rated only up to 1.75”. A suitable 20-inch tube for a 2.0-inch tyre is therefore required. Inner tubes are available at $10 each. 3 3-in-1 Hook Adapter Our custom hook adapter changes the folded wheel position and provides the clearance required for the wider Billy Bonkers tyre. Java Neo ECO uses its dedicated ECO-compatible version. 4 Custom Easywheel Extender Our Java Neo easywheel extender works together with the correct hook adapter to preserve practical folded rolling and tyre-to-easywheel clearance. Why Does The Java Neo Need Additional Parts? Billy Bonkers uses a wider 20 × 2.00 profile than the standard tyre configuration found on many Java Neo bicycles. Once the bicycle is folded, tyre width affects the relationship between the front wheel, rear wheel, main frame, hook and easywheel system. Simply installing the wider tyres without correcting these clearances can affect how the bicycle folds or rolls. Our custom Java Neo Easywheel Extender and Billy Bonkers-compatible 3-in-1 Hook Adapter are used together to create a properly configured folded setup. For a proper Java Neo conversion: Do not assess the tyre in isolation. Wheel size, tyre width, hook position, easywheel setup and folded clearance all work together.

The stock Java Neo ECO easywheel is too wide for the Billy Bonkers configuration and can come into contact with the tyre when folded. It therefore needs to be replaced with the slimmer standard-type easywheel. The ECO also uses its own version of our 3-in-1 Hook Adapter. The Custom Java Neo Easywheel Extender remains part of the complete setup.

Using Billy Bonkers On Other 20” 406 Foldies? Billy Bonkers is not limited to Java Neo bicycles. It can also be considered for compatible 20-inch ISO 406 folding bicycles. The Java Neo-specific Hook Adapter and Easywheel Extender are not required for a conventional compatible bifold setup. However, because Billy Bonkers is a 2.0-inch-wide tyre, frame, fork, brake and wheel clearance should always be checked before proceeding. Actual fitted tyre width can also vary depending on the rim.

View 3-in-1 Hook Adapter View Easywheel Extender Read Billy Bonkers Setup Guide Billy Bonkers 20” & Java Neo FAQ Common questions about fitting Schwalbe Billy Bonkers 50-406 tyres to Java Neo and other 20-inch folding bicycles. Does Schwalbe Billy Bonkers 20 × 2.00 fit Java Neo 20”? Yes. It can be configured for Java Neo 20-inch models including aluminium, carbon-fork, full-carbon, J-AIR, ECO and earlier 20-inch versions. Supporting parts are required to maintain the correct folding and rolling setup. Can I simply replace my original Java Neo tyres with Billy Bonkers? No. The wider 2.0-inch tyre changes folded clearances. A correct Java Neo setup requires the compatible 3-in-1 Hook Adapter, Custom Easywheel Extender and suitable 20-inch 2.0 inner tubes. Why must the Java Neo inner tube be replaced? The original Java Neo inner tube is rated only up to 1.75 inches. Billy Bonkers is 2.0 inches wide, so a suitable 20-inch tube rated for the wider tyre is required. Our replacement tubes are $10 each. Is the Java Neo ECO setup different? Yes. The ECO uses its dedicated version of the 3-in-1 Hook Adapter. Its original easywheel is also too wide for the Billy Bonkers folded setup, so it needs to be replaced with a slimmer easywheel. Does Java Neo J-AIR require a different setup? Billy Bonkers 20 × 2.00 is compatible with the 20-inch J-AIR. It uses the standard compatible Java Neo Billy Bonkers hook/extender setup rather than the ECO-specific hook version. Can Billy Bonkers be fitted to other 20-inch folding bikes? Yes, where the bicycle uses compatible 406 wheels and has sufficient frame and fork clearance. The Java Neo-specific hook adapter and extender are not required for a compatible conventional bifold, but clearance should always be assessed before installation. Is this listing for one tyre or a pair? This listing is for one tyre. Select quantity 2 if you require a front-and-rear pair. How much is installation? Front-and-rear installation is available separately at $25 per bicycle. Additional parts required for a Java Neo Billy Bonkers conversion are sold separately.
