BONGO JUNGLE FRAME

Riding with rhythm and moving with the flow of nature, the Bongo Jungle is a blank canvas ready to head wherever your imagination takes it. Blending modern trail bike geometry with the character and ride feel of chromoly steel, the Bongo Jungle is built for riders who enjoy everything from long pedaling days and steep climbs to fast descents and multi-day bikepacking trips.

Its seamless, heat-treated, and multi-butted MKPT Chromoly tubing strikes a balanced mix of durability, comfort, and weight. A steep 73-degree seat angle keeps the rider centered over the bottom bracket for efficient climbing, while the Groovy York design allows the Bongo Jungle to maintain a short 425mm chainstay without relying on oversized welded plates or excessive chainstay shaping.

Up front, a 67.5-degree head angle paired with a longer reach and wheelbase adds stability and confidence on technical descents. The versatility of steel also gives us the freedom to include practical details such as accessory mounts, rack and fender mounts, and additional bottle cage mounts for riders who like to explore further.

Additional features including stealth dropper post routing, ED coating inside and out, and our signature steel fin dropout complete the package, making the Bongo Jungle a modern steel hardtail mountain bike that feels equally at home on trails, long rides, and off-grid adventures.
