A good airbag setup starts with a jump that matches your skill level, riding style, and landing system. The Gravity Jump Builder helps you create a custom ramp plan instead of guessing at height, curve, takeoff angle, or material needs.
Use it to design jumps for:
Whether you are building a smaller beginner jump or a larger progression ramp, the builder gives you a clear plan before you start cutting wood.
The builder supports different ramp layouts depending on the size of your design.
For smaller jumps, it can create a simple one-piece side panel design that fits efficiently on standard plywood.
For taller or longer jumps, it can generate split-side designs that use multiple plywood panels and bolt together into a larger ramp structure.
This gives riders and builders more flexibility than a single fixed-size plan.
Whether you’re brand new to mountain biking, looking to get back in the saddle, or a veteran rider who needs all the practice they can get, you deserve a bike ramp design that works for you.
Designing and creating a DIY bike ramp isn’t as difficult as you might think: it just takes a little know-how.
