How to Build a Wooden Bike Ramp | DIY Plans & Build Steps

Rolling your own ramp is straightforward with basic tools and a weekend afternoon. The trick is matching the curve to your riding style and keeping the whole thing sturdy enough to handle repeated landings. Below are core build steps, material options, and safety checks that apply whether building for a BMX, mountain bike, or skateboard.

What Tools and Materials Do You Need?

You can build a solid ramp with common workshop gear. Plywood forms the two identical side panels and the riding surface; 2x4s create the internal frame that prevents flex.

• Plywood: One 4×8 sheet of 3/4-inch exterior-grade is typical for both side panels and deck if the ramp is narrow (24 inches or so). For a wider ramp, an additional sheet is needed for the riding surface.
• Lumber: 2x4s or 2x3s for cross braces. Plan on roughly six to eight pieces, each cut to your ramp’s width.
• Fasteners: 2-inch deck screws. Countersink them on the riding surface so tire contact stays smooth.
• Tools: Jigsaw or circular saw for cutting the curve, drill with driver bits, tape measure, pencil, clamps, and a piece of string or rope for marking the arc.
• Optional extras: Wood glue for extra joint strength, and a sheet of thin metal (like aluminum) to cap the takeoff edge if riding skateboards or scooters.

The best wooden bike ramp designs start with matching side-panel templates, so cutting one accurately makes or breaks the build.

Marking and Cutting the Curve

The most reliable method for identical side panels is the string arc: tie a rope to a pivot point, stretch it taut, hold a pencil at the other end, and trace a smooth arc onto the plywood. Adjust by changing the pivot location or string length.

• For a mellow kicker: Use a pivot about 6 feet back and a string length of around 5 feet. The arc will rise roughly 12–18 inches over a 3-foot transition.
• For a steeper jump: Bring the pivot closer (4 feet back) and use a shorter string. Ensure your plywood can bend without cracking.
• The template trick: Cut the first side panel with a jigsaw, clamp it on top of the second sheet, trace the outline, and cut. This guarantees both sides match.

DO NOT force plywood into a curve tighter than its natural bending radius — it can snap during assembly. If it resists, ease the cut or add a longer transition.

Building the Frame and Installing the Riding Surface

Once both side panels are cut, the frame goes together fast. Lay both panels flat on a level surface, parallel, with curved edges aligned upward. Install cross braces between the panels: one at the bottom (entry), one at the top (takeoff edge), and two or three more spaced roughly every 18 inches.

• Attachment: Drive screws through the side panels into the ends of each brace. Use pilot holes to prevent splitting near the edges.
• Deck installation: Lay the riding-surface plywood on the frame. Start screwing at the bottom edge, working upward and bending the plywood gradually to match the curve. Use four or more screws per cross member.
• Countersink every screw head on the deck so fasteners sit flush. A raised screw head can catch a tire or pedal and cause a crash.

Place the ramp on level ground and test by hand. Push down near the top edge — if it flexes, add another cross brace or denser screws. Sand or file all exposed edges to remove splinters. For skateboards or scooters, cap the takeoff edge with sheet metal to prevent binding; file the metal edge smooth.
