WeThePeople Havoc: 20 vs 22 and the Disc-Brake Trail Build
The WeThePeople Havoc combines a trail-oriented complete BMX with a hydraulic disc brake in two wheel formats. Comparing the 20 and 22 means looking at frame proportions and tire specifications as well as the brake. Neither version should be selected simply because a larger number sounds more advanced.
WeThePeople Havoc braking and trail equipment
Both the Havoc 20 and Havoc 22 list full-4130-chromoly frames with disc mounts, Magura MT4 hydraulic brakes with 140mm rotors, and Éclat Exile Disc cassette rear hubs. The product descriptions connect the project to the Chaos Machine aftermarket frame as a starting point.
Both also list 32mm-offset forks and 28-tooth sprockets paired with nine-tooth cassette drivers. Their gyro fields state that there are no holes for removable tabs. For a rider expecting a conventional park rotor setup, that last detail deserves discussion before purchase. A hydraulic wheel brake and a headset cable rotor answer different equipment questions.
The 20 and 22 have different proportions
The 20-inch model lists a 21.35-inch top tube, a 14.1-inch chainstay setting within a 13.9–14.6-inch range, and 9.5-inch standover. Its tires are Éclat Vapour, listed at 20 × 2.4 inches front and 20 × 2.25 inches rear.
The 22-inch model moves to a 22.25-inch top tube, a 14.35-inch chainstay setting within a 14–14.75-inch range, and 9.75-inch standover. It specifies 22 × 2.3-inch WeThePeople Overbite tires at both ends. Both head angles are listed as 74.25 degrees. These are related designs with distinct dimensions, not a single frame size wearing two interchangeable wheelsets.
Bring your existing bike's measurements to a fitting and compare the space available while standing. Also ask who can supply the correct tire sizes and service the brake locally. Documenting that support is especially useful before committing to the less familiar wheel format. Published geometry helps narrow the choice; it does not replace an actual fit assessment.
If suspension is part of your requirement, our Swamp Master article explains that separate crossover concept. Other references appear in the WeThePeople collection.
FAQ: choosing a Havoc wheel format
Does the 22 get a different listed brake model?
No. Both pages specify the Magura MT4 with a 140mm rotor.
Can I compare gearing from the sprocket alone?
No. Include the rear driver and wheel diameter; matching tooth counts do not mean identical development with different wheels.
Does this article describe a universal disc conversion?
No. It describes complete bikes with documented disc mounts and hubs. Assess any proposed conversion separately.
The WeThePeople Havoc decision should bring together wheel format, standing fit and the maintenance arrangements for its specific disc-equipped build.
