Planning Your Jump: Location, Location, Location!

Before you even think about shoveling dirt, planning is paramount. Choosing the right location is the first crucial step in ensuring your jump is both fun and safe. Consider these factors:

  • Land Ownership & Permissions: This is the most important thing to consider first! Do you own the land? If not, you absolutely must get permission from the landowner before you even think about digging. Building jumps on private or public land without authorization can lead to serious consequences, including fines and legal action. Don't risk it; always ask first.
  • Trail Traffic: Avoid building your jump on a heavily used trail. High-traffic areas increase the risk of collisions and injuries. Look for a spot slightly off the main trail or in a less frequented area. Communication is also important. Once you have built your mountain bike jump make sure to inform the local riders, so that they are aware of the new trail feature.
  • Clearance & Run-Out: You'll need ample space before and after the jump. The approach (run-in) should be smooth and free of obstacles, allowing you to gain enough speed comfortably. The landing area (run-out) needs to be clear and long enough to safely absorb your landing, even if you don't stick it perfectly. Insufficient run-out space is a recipe for disaster.
  • Terrain & Soil: The ideal terrain is slightly sloping, allowing for a natural flow. Consider the soil type – sandy soil might be too loose, while clay can become slippery when wet. Loamy soil is generally the best option as it compacts well and drains effectively. Think about drainage too, a boggy area will not be suitable!
  • Natural Features: Can you incorporate existing features like a small rise or a natural depression into your jump design? Working with the natural terrain can save you a lot of effort and create a more organic-feeling jump. Check for any tree stumps or large rocks that can be incorporated into your design as well.
  • Visibility: Ensure the jump is visible to riders approaching from both directions. Blind corners or hidden jumps are extremely dangerous. Clear any vegetation that might obstruct the view.
  • Environmental Impact: Be mindful of the surrounding environment. Avoid damaging trees, disturbing wildlife habitats, or causing erosion. Keep your construction footprint as small as possible. If you have impacted any of these, make sure to repair it.

Think about the type of jump you want to build. A small roller is a great starting point for beginners, while more advanced riders might crave a gap jump or a step-up. Consider your skill level and the skill levels of those who will be using the jump.

Finally, once you have your location, take some photos of it and create a basic plan of your mountain bike jump. This can be a hand-drawn sketch or something digital using online tools. This ensures that when you come to building the jump, you know exactly where you are going to build it.

Designing Your Jump: Size, Shape, and Style

Now that you've secured the perfect location, it's time to get down to the nitty-gritty of jump design. This is where you determine the size, shape, and style of your jump, all of which will impact its difficulty and the type of riding experience it offers.

  • Jump Type: Different types of jumps cater to different skill levels and preferences. Here are a few common options:
    • Roller: A smooth, rounded mound that allows you to maintain speed and flow. Great for beginners and for practicing pumping techniques.
    • Tabletop: A jump with a flat top between the takeoff and landing. Tabletops are forgiving and allow riders to land anywhere on the flat surface, making them ideal for learning new tricks.
    • Gap Jump: A jump with a gap between the takeoff and landing. Gap jumps require more commitment and skill, as you need to clear the entire gap to land safely.
    • Step-Up/Step-Down: A jump where the landing is higher (step-up) or lower (step-down) than the takeoff. These jumps can be tricky and require precise timing and control.
  • Size Matters: The size of your jump should be proportionate to your skill level and the available space. Start small and gradually increase the size as you become more comfortable. A small roller might be only a foot or two high, while a larger gap jump could be several feet tall and long.
  • Takeoff Angle: The angle of the takeoff ramp is crucial for determining the trajectory of your jump. A steeper angle will result in a higher, more vertical jump, while a shallower angle will produce a lower, more horizontal jump. Experiment to find the angle that feels best for you.
  • Landing Slope: The slope of the landing area should match the trajectory of your jump. A smooth, gradual slope will provide a more forgiving landing, while a steep landing can be jarring and difficult to control. Aim for a landing slope that is slightly less steep than the takeoff angle.
  • Smooth Transitions: Ensure smooth transitions between the takeoff, the flat top (if it's a tabletop), and the landing. Abrupt transitions can cause you to lose balance or get bucked off your bike. Use a shovel to blend the transitions seamlessly.
  • Drainage: Incorporate drainage into your design to prevent water from pooling on the jump. This can be as simple as creating a slight slope on the jump's surface or digging drainage channels to divert water away from the area. You can use sand, gravel, or geo-textile fabric to improve drainage.
  • Progression: If you're building a series of jumps, consider the progression of difficulty. Start with smaller, easier jumps and gradually increase the size and complexity as you move along the trail. This will allow riders to build their skills and confidence gradually.

Always prioritize safety in your design. Avoid creating features that are beyond your skill level or that could pose a danger to other riders. When creating your design, take the time to consult with other experienced riders and gather feedback on your ideas. Their insights can help you identify potential problems and improve your design.

Building Your Jump: Tools, Materials, and Techniques

Alright, design locked in? It's time for the fun part – building your jump! This stage requires some elbow grease, the right tools, and a good understanding of basic construction techniques. Let's dive in:

  • Essential Tools: Here's a list of tools you'll likely need:
    • Shovels: Round-point shovels are great for digging and moving dirt, while square-point shovels are useful for shaping and packing.
    • Rakes: Use rakes to smooth out the surface of the jump and remove any rocks or debris.
    • Tamper: A tamper is essential for compacting the dirt and creating a solid, durable jump. You can rent a gas-powered tamper for larger projects.
    • Wheelbarrow: A wheelbarrow will make it much easier to transport dirt and materials to the construction site.
    • Measuring Tape: A measuring tape is essential for ensuring accurate dimensions and angles.
    • Level: A level will help you create a smooth, even surface on the takeoff and landing.
    • Pickaxe: A pickaxe can be helpful for breaking up hard or rocky soil.
    • Gloves: Protect your hands from blisters and cuts with a good pair of work gloves.
    • Safety Glasses: Protect your eyes from flying debris with safety glasses.
  • Materials Matter: The primary material for building your jump will be dirt, but you may also need other materials:
    • Topsoil: Topsoil is the uppermost layer of soil and is rich in organic matter. It's ideal for shaping the jump's surface and promoting vegetation growth.
    • Subsoil: Subsoil is the layer of soil beneath the topsoil. It's typically less fertile but can be used to build the jump's core.
    • Gravel: Gravel can be used to improve drainage and prevent erosion.
    • Wood: Wood can be used to create retaining walls or support structures, especially for larger jumps.
    • Geo-textile Fabric: Geo-textile fabric can be used to separate different layers of soil and prevent them from mixing. This can improve drainage and stability.
  • Construction Techniques:
    • Start with a Solid Base: Before you start piling up dirt, create a solid base for your jump. Remove any loose rocks or debris and compact the soil thoroughly.
    • Layer and Compact: Build the jump in layers, compacting each layer thoroughly before adding the next. This will create a stronger, more durable jump.
    • Shape the Takeoff and Landing: Use a shovel and rake to shape the takeoff and landing ramps to the desired angles and curves. Pay close attention to the transitions between the different sections of the jump.
    • Pack it Tight: Use a tamper to pack the dirt as tightly as possible. This will help prevent the jump from collapsing or eroding.
    • Add Drainage: Incorporate drainage features into your design to prevent water from pooling on the jump. This can be as simple as creating a slight slope on the jump's surface or digging drainage channels.
    • Protect the Surface: Consider covering the jump's surface with topsoil or geo-textile fabric to prevent erosion and promote vegetation growth.

Remember to take your time and pay attention to detail. A well-built jump will be safer, more durable, and more fun to ride. If you're unsure about any aspect of the construction process, don't hesitate to consult with experienced trail builders or seek professional guidance.

Testing and Maintenance: Ride it, Fix it, Repeat!

Congratulations, you've built your mountain bike jump! But the work isn't over yet. Testing and maintenance are crucial for ensuring the jump remains safe and fun to ride for years to come.

  • Start Small: Before you start launching yourself off the jump at full speed, take some time to test it out at a slower pace. Roll over the jump a few times to get a feel for the takeoff and landing. Gradually increase your speed as you become more comfortable.
  • Inspect Regularly: Regularly inspect the jump for any signs of damage or wear. Look for cracks, erosion, or loose soil. Pay close attention to the takeoff and landing areas, as these are the most vulnerable to damage.
  • Maintenance is Key: Perform regular maintenance to keep the jump in good condition. This may include patching cracks, adding soil to eroded areas, or re-shaping the takeoff and landing ramps.
  • Address Drainage Issues: Make sure the drainage system is working properly. Clear any debris from drainage channels and ensure that water is flowing away from the jump.
  • Communicate with Riders: Encourage riders to report any problems they encounter with the jump. This will help you identify potential issues and address them promptly.
  • Seasonal Maintenance: Perform seasonal maintenance to prepare the jump for changing weather conditions. In the fall, clear away leaves and debris to prevent them from accumulating and causing drainage problems. In the spring, repair any damage caused by winter weather.
  • Respect the Environment: Be mindful of the surrounding environment when performing maintenance. Avoid using harsh chemicals or disturbing wildlife habitats.

Building and maintaining a mountain bike jump is an ongoing process. Be prepared to invest time and effort into keeping your jump in top condition. With proper care and attention, your jump will provide you and other riders with years of enjoyment.
