In creating the image above I was reminded of a guy that emailed me about a year after this calculator was first posted to tell me he was using it to jump cars! He wanted to talk to me on the phone. I panicked because spending time in court five states away immediately crossed my mind.

However, he was grateful, thanked me repeatedly, asked how I did the math, and if I could help him with the takeoff ramp. The drawing above assumes circular transitions, but the calculator assumes nothing other than the angle at takeoff. The car jumper was building nearly dead straight transitions, or wedges, a little rough even with suspension depending on his speed. If rough enough it could possibly change the range of his flight. My guess is that he never skated vert or built ramps before to realize just how smooth a takeoff could be.

He was trying the witchcraft method before he found this page. There are MANY flavors of jumps, but they come down to two types, one that is planar or flat, that is linear, and one that has a curve or radius all the way to the lip edge.

These are safer? They still depend on rider input, but the variation is not as large or unpredictable. Ski and snowboard jump are often like this, a curved entry into a long plane takeoff. However, they usually require a significant amount of soil as compared to curved transitions to the lip.

The arched or curved types come in an large range of possibilities, not one plane, flat. Flat or curved, the transition to the lip is key. Curved lips can have a circular or elliptical radius or arc of an nearly infinite range.

Riders may be able to manipulate the parabolic arc of flight more easily, creating their own flow within the bounds of our natural Laws of course. Clipless Shoes Flat Pedal Shoes. Backpacks Hydration Packs. Typical Dirt Jumping Mountain Bike. As a test, approach the bike from the front and pinch the wheel between your legs.

Grab the bars and turn them side to side a few times. A flexible fork one that you can see twisting should be avoided. Chain Retention : If the bike is single-speed, make sure that there is some sort of chain tensioner on the dropouts.

Horizontal dropouts with a bolt-on rear axle are the best for single-speed dirt jumpers. If the bike has gears, make sure that it has a chainguide on the front sprocket. Losing a chain while dirt jumping never ends well. Because of this, look for wheels that have 36 spokes and always run at least 45 psi in your tires.

Tires : Tires with small knobs or smooth tread patterns are preferred for dirt jumping and skatepark use. Most good fork manufacturers also make forks specifically for dirt jumping. We recommend Marzocchi, because they make great forks, and they keep their prices reasonable. Check out the Marzocchi Dirt Jumper 1. Since dirt jumpers commonly jump over 10 or even 15 feet in height, safety equipment is essential.

A good quality helmet either a full face helmet or very good protection is needed. A standard MTB helmet, usually won't cut it. Good gloves and Good Firm Shoe are essential, and shin and elbow guards are a good idea as well.

You can take some nasty falls dirt jumping, so don't push you limits too far, and don't try tricks that you have no chance of landing safely.

This is especially true with inverted tricks like back flips, where even a slight mistake can cause a serious injury or death. If you don't know how to, and you're not comfortable with it, then don't do it.
