If the bunny hops too flat, new tricks are needed, such as this one: you can overcome any obstacle with the lunge. And this is how it works:
Up and down with the front wheel
You don't need a lot of speed for this move - walking pace is enough. The first action: a push-up over the handlebars, with your legs bent too. This creates tension for the opening movement. Just before you ride onto the tree trunk, use the manual movement to take the weight off the front wheel. How does it work? By dynamically stretching backwards and upwards (see photo).
Consequence: The front wheel rises. Now it's all about the right timing. You want to place the front wheel fairly centred on the tree trunk.
Timing is everything!
As soon as you have placed the front wheel on the trunk, the next action comes immediately: you push off the front wheel. At the same time, your hips impulsively shoot upwards. As a result, you leap forwards. The momentum carries the rear over the obstacle. It doesn't matter if the bashguard or chainring touches down - the momentum carries you on immediately. Caution: The whole movement happens with the cranks in a horizontal position.
Over with it
Try to push the bike forwards underneath you. Your body position will automatically shift backwards. Slight rear wheel contact with the obstacle is not dangerous due to the low height.
Landing
Ideally, you should touch down with both wheels at the same time. If the rear wheel gets stuck on the obstacle, you shift the centre of gravity even further back - the rear will then follow at the latest.
