These small, low and tough bikes are built for aggressive riding on parks, pump tracks and jumps. Compared to other types of mountain bikes dirt jump (or DJ) bikes have a shorter wheelbase, lower standover height and a rigid or short-travel fork which allows for precise handling and control in the air and on the track. Dirt jump bikes need to be strong and durable and so boast features such as reinforced frames, thick chains and platform pedals that allow for better grip.

Advantages of Second Hand Dirt Jump Bikes

Cost Efficiency:

Purchasing a used dirt jumper presents substantial cost savings over buying new – you can score quality frames and components for a fraction of the original price. Take advantage of the high initial depreciation as many dirt jump bikes are ridden minimally by their original owners. Just be sure to examine the frame thoroughly for cracks before purchasing. Overall, used bikes allow riders to access pro-level equipment they may not otherwise afford like light chromoly frames and premium forks.

Upgradability:

Many second-hand purchases already have upgrades making them prime for customisation. Tweak cockpit fit by swapping stems, bars and pedals to match your preferences. Dial in tyre traction by experimenting with different tread compounds and pressures for your local dirt. As skills progress, drivetrain and braking power can be enhanced down the road. Starting with a solid used frame gives you an ideal platform to tailor and upgrade perfectly in sync with evolving riding abilities.

Environmental Impact:

Extending dirt jump bikes’ usable lifespan by reselling or purchasing second-hand promotes sustainability and reduces waste in mountain biking. Sharing the stoke by passing bikes amongst the dirt jump community keeps precious gear out of landfills. Repurposing quality frames and components embodies the eco-conscious ethos prevalent in action sports.

Choosing the Right Dirt Jump Bike

Skill Level Considerations:

If you’re just getting into dirt jumps, a quality hardtail with 80-100mm of front suspension travel is ideal. The slight squish upfront cushions landings without dampening pop off lips. Chromoly or alloy frames withstand abuse well and provide snappy handling. As skills progress, riders may eventually upgrade to lighter frames with dialled geometry for whipping tricks.

Advanced riders should look for chromoly construction for durability at lower weight along with responsive, dirt jump-specific frame geometry. Top tube lengths between 21-22′′ suit a wide variety of riding styles. Short chainstays (13-13.25′′) increase back wheel traction and pop. Aggressive head tube angles (68-69°) give sharp, nimble steering in the air. Carefully consider your riding style and skill level when choosing frame geometry.

Frame Material Options:

Aluminium dirt jump frames withstand abuse surprisingly well while keeping costs down. Race-ready chromoly frames offer the best strength-to-weight ratio for throwing advanced tricks while retaining resale value. High-end options like Reynolds 853 chrome-moly combine featherweight responsiveness with incredible durability.

If hucking big booters at the bike park, aluminium and chromoly’s durability is recommended over fragile, lightweight carbon which can crack under harsh impacts. Weight weenies can run carbon bars, seats and wheels though for rotating mass savings. Identify the materials that best match your budget, weight considerations and just how hard you plan to huck!

Key Features to Consider

Frame Integrity:

Carefully inspect the frame for any cracks, dents or signs of stress which can severely compromise integrity. Check all welds closely for cracking. Issues like head tube elongation from repeated fork impacts can alter geometry and handling. When test riding, listen and feel for any creaking which may indicate fatigue damage. Since the frame shoulders the burden of harsh landings, ensure it’s free of defects before purchasing.

Suspension System:

A dirt jumper’s suspension fork or rigid setup handles the brunt of harsh landings, so check them over thoroughly. Ensure the fork smoothly compresses and rebounds without leaking oil. Rear suspensions are less common but check shocks for leaks or damage if equipped. Quality suspension is essential for soaking up repetitive hits.

Brake Performance:

Linear-pull brakes offer modulation for controlling speed entering kickers. Disc varieties provide increased power for slowing and stability from all-out efforts. Ensure the levers have smooth action and the rotors are free of glazing or corrosion. Remember to consider your riding style and skill level when eyeing brake configurations.

Wheel and Tyre Condition:

Inspect rims and spokes for trueness, hub engagement for play, and tyres for adequate tread depth. Most dirt jumpers roll 26” or 24” wheels – smaller diameters increase strength and manoeuvrability which are beneficial for whippy aerial movements. Ensure the wheels suit your chosen riding style.
