What You Need to Build a Basic Bicycle Ramp
A rideable bicycle ramp is a plywood surface mounted on a wooden frame, angled between 15 and 45 degrees depending on what tricks or skills you want to practice. The simplest version uses one sheet of plywood, four 2x4 boards, and a handful of bolts. You do not need welding, concrete, or special tools — a circular saw, a drill, and a level are enough to build one that will last years.
The frame sits on the ground and holds the plywood at an angle. The steeper the angle, the harder the ramp is to ride, but also the more dramatic the tricks become possible. Most beginners start with a 20-degree angle, which is steep enough to feel like progress but shallow enough that falling does not hurt as much.
Budget roughly $80 to $150 for materials, depending on plywood grade and whether you already own a drill and saw. The work takes a weekend afternoon if you have a helper and a flat place to build.
Key Takeaways
- A basic ramp uses one sheet of 3/4-inch plywood, four 2x4 boards, bolts, and wood screws — all available at any home improvement store.
- The angle of the ramp determines difficulty: 15 to 20 degrees is beginner-friendly, 25 to 35 degrees is intermediate, and 40+ degrees is for experienced riders.
- The frame must be braced diagonally to prevent collapse, and the plywood surface must be sealed or painted to resist water and splinters.
- A finished ramp is heavy enough that you will need help moving it, so build it where you plan to use it or have a plan to transport it.
Choosing Your Angle and Ramp Size
The angle of your ramp controls what you can do on it. A 15-degree ramp is nearly a gentle hill — good for practicing balance and getting comfortable with the feeling of riding uphill. A 20-degree ramp is the standard for learning tricks like manuals and small jumps. A 30-degree ramp is noticeably steep and requires more speed and commitment. Anything above 35 degrees is for riders who have already spent time on smaller ramps.
Most homemade ramps are 8 feet long and 4 feet wide, which matches a standard sheet of plywood. An 8-foot length gives you enough run-up to build speed and enough landing space to practice safely. If you have room and want to build bigger, a 12-foot ramp with two sheets of plywood side by side is possible, but it becomes harder to move and requires more bracing.
Write down your chosen angle and length before you buy materials. The angle determines how tall the back of the ramp will be — a 20-degree angle on an 8-foot ramp puts the back edge about 3 feet high. Check that your space has enough clearance above the ramp for you to ride safely.
Materials and Tools You Will Need
For an 8-foot ramp at a 20-degree angle, gather one sheet of 3/4-inch exterior plywood, four 2x4 boards (each 8 feet long), one 2x4 cut to 4 feet for bracing, sixteen 1/2-inch bolts with washers and lock nuts, a box of 2.5-inch wood screws, wood sealant or exterior paint, and sandpaper.
Tools required are a circular saw or miter saw, a drill with a 1/2-inch bit, a socket wrench or adjustable wrench, a level, a tape measure, a pencil, and a square. If you do not own a saw, most home improvement stores will make straight cuts for free or a small fee — you can ask them to cut your 2x4s to length and your plywood to size before you leave the store.
A helper makes the work faster and safer, especially when flipping the frame and lifting the plywood into place. If you are working alone, have clamps ready to hold pieces while you drill and bolt them.
Building the Frame and Bracing
The frame is two long 2x4s (the sides) connected by two short 2x4s (the front and back). Lay the two long 2x4s parallel on the ground, 4 feet apart. At one end, bolt a short 2x4 across them — this is the front of the ramp and stays at ground level. At the other end, bolt the second short 2x4 — this is the back, and it will be raised up to create the angle.
Measure the height you need at the back based on your angle. For a 20-degree angle on an 8-foot ramp, the back should be about 2 feet 10 inches high. Cut four blocks of 2x4 to that height and bolt them under the back 2x4 to lift it. The frame now looks like a rectangle tilted up at one end.
Add diagonal bracing to prevent the frame from collapsing sideways. Cut a 2x4 to fit diagonally from the top of one back block to the bottom of the opposite front corner, then bolt it in place. Repeat on the other side. The frame should feel rigid when you push on it — if it flexes, add more bolts or bracing.
Attaching the Plywood Surface
Lay the plywood sheet on top of the frame so that it overhangs the front by about 6 inches and sits flush with the back. The plywood should rest evenly on all four frame pieces. Drill pilot holes through the plywood into the frame every 12 inches, then drive 2.5-inch wood screws through the plywood into the 2x4s below. Space the screws in a grid pattern so the plywood does not warp or flex under your weight.
Sand the entire surface with medium-grit sandpaper to smooth rough spots and splinters. Pay special attention to the edges and the front lip where your tires will make contact. Sand until the surface feels smooth to your hand.
Seal or paint the plywood with exterior-grade wood sealant or paint. This protects the wood from rain and extends the life of the ramp by years. Two coats are better than one. Let the sealant dry completely before riding — check the label for drying time, which is usually 24 to 48 hours.
Finishing and Safety Checks
Before you ride, walk the ramp and check for loose bolts, soft spots in the wood, or gaps between the plywood and frame. Tighten any bolts that have come loose. If you find soft wood, that section may be rotting and should be replaced before you ride.
Check that the ramp is level side to side using a level placed across the width. If one side is higher than the other, your bike will pull to one side when you ride. Adjust the height of the blocks under the back until the ramp is level.
Wear a helmet and pads every time you ride, especially when learning. Start at the bottom of the ramp and work your way up to higher speeds and tricks. A ramp that feels solid and safe is one you will use for years.
Maintaining Your Ramp Over Time
Check the bolts every few months and tighten any that have loosened from vibration and use. Inspect the plywood surface for cracks, soft spots, or areas where the sealant has worn away. Small cracks can be filled with wood filler, but large cracks or soft spots mean that section of plywood should be replaced.
Reseal or repaint the surface every one to two years, depending on weather and how much you ride. A ramp in direct sun and rain will need more frequent sealing than one under a roof or in a garage. Keeping the surface sealed prevents water from soaking into the wood and causing rot.
If you move the ramp, inspect the frame for cracks or bent bolts. A ramp that has been moved roughly may have hidden damage that shows up the next time you ride. Tighten everything and test it on flat ground before you use it again.
Frequently Asked Questions
What angle should I start with if I have never ridden a ramp before?
Start with 15 to 20 degrees. A 15-degree ramp feels almost like a gentle hill and lets you get used to the feeling of riding uphill without fear. Once you are comfortable, you can build a steeper ramp or adjust the blocks under the back to increase the angle of the one you have.
Can I use plywood thinner than 3/4 inch?
No. Thinner plywood will flex and crack under your weight, especially in the middle of the ramp where the stress is greatest. 3/4-inch exterior plywood is the minimum for a ramp that will last. Some builders use 1-inch plywood for extra durability, but it costs more and is heavier to move.
Do I need to put the ramp on concrete or can it sit on grass?
Grass or dirt will work, but the ramp will sink unevenly over time as the ground settles. A flat, hard surface like concrete or packed gravel is better. If you must use grass, place plywood sheets or concrete pavers under the front and back to distribute the weight and keep the ramp level.
How much does a finished ramp weigh?
An 8-foot ramp with a 3/4-inch plywood surface and a 2x4 frame weighs roughly 150 to 200 pounds. You will need at least one helper to move it safely, or a truck and ramps to load it. Build it where you plan to use it if moving is difficult.
What should I do if the plywood starts to splinter?
Sand the splintered area smooth with medium-grit sandpaper, then reseal it with wood sealant. If splinters keep coming back in the same spot, that area of plywood may be damaged and should be replaced. Splinters are a sign that the sealant is wearing away and water is getting into the wood.
