Protocol: Bunny Hop – American Style (Sequential Jump)
Goal: Learn the bunny hop by lifting both wheels off the ground in sequence, so you can clear obstacles (logs, potholes) without losing speed.
Unlike the "English Hop" (where the rider pulls both wheels up at the same time), the American bunny hop uses the physics of leverage. You lift the front wheel first (a Manual), then jump explosively with your legs and "grab" the rear end of the bike. It is a key skill for advanced mountain bike jumping technique.
Glossary of Technical Terms
1. Biomechanics: Anatomy of the Jump (the J-Motion)
A bunny hop is not a jump OFF the bike, it is a jump WITH the bike. Your body movement traces the letter J (Back-Up-Forward).
| Phase | Action | Details |
|---|---|---|
| 1. Pre-load | Compress | Quickly compress your body and the bike toward the ground. Like a spring. |
| 2. Manual | Back | Drive your hips back explosively. The front wheel must go high (aim for the sky). |
| 3. Explosion | Up (Jump) | While the front wheel is in the air, your legs explode vertically. You jump, the bike follows. |
| 4. Scoop | Pull | The moment the rear wheel leaves the ground, point your toes down and pull the pedals backward and up. |
| 5. Leveling | Forward | Push your arms forward hard. This lifts the rear wheel and levels the bike for landing. |
2. Training Plan: Progression by Level
| Drill | Level | Goal |
|---|---|---|
| Rear Wheel Lift | Level 1 | Lifting only the rear wheel. Focus on the "Scoop" foot movement. Isolating the rear-end lift. |
| Cardboard Box Jump | Level 2 | Jumping over a cardboard box (safe to hit). Height 20-30cm. Breaking through the mental barrier. |
| Speed Hops | Level 3 | Clearing markers at 25 km/h. Reaction speed, flow and precise landings. |
3. Most Common Mistakes (Troubleshooting)
You stiffen up in the air and lose control. Fix: Stay dynamic. Your body must keep moving (back-up-forward) until you land.
The front wheel clears the obstacle, but the rear wheel smacks into it ("Snake bite"). Fix: Jump earlier. Start the Manual 1-2 meters before the obstacle.
4. Practical Application: Where to Use the Bunny Hop on the Trail?
Many riders think the bunny hop is just a parking-lot trick. In reality, it is one of the most useful tools for keeping your speed and flow on technical terrain.
Instead of letting your wheels smash into every hole and slow you down, use a bunny hop to fly over them. This is the key to riding smoothly.
Advanced riders use the jump to change their path mid-air, landing on a cleaner part of the trail or in a better position for the next corner.
The Physiology of Explosiveness
A bunny hop is a maximum-power movement that recruits Fast-Twitch (Type II) muscle fibers and the ATP-PC energy system (lasting up to 10 seconds).
Training tip: Do sets with long rests (2-3 min) to restore your phosphocreatine stores. A tired rider cannot jump high.

Pro Tips for Level 3
This is a must for learning proper technique. If you ride clipless pedals (SPD), you are fooling yourself that you can "Scoop". Flat pedals force you to learn how to keep your feet planted correctly.
On the trail, a small rock or root can act as a "springboard". Hit it with your rear wheel on purpose as you hop. It will launch you even higher.
