Wobble
Your wheel starts oscillating side to side. Your legs tense up, which makes it worse. The wobble feeds on tension - the harder you fight it, the bigger it gets.
Why it happens
Wobbles are a feedback loop. A small lateral movement triggers a correction from your legs, but if your muscles are stiff, the correction overshoots. That overshoot triggers another correction. Back and forth, amplifying.
Speed makes it worse. So does fatigue, rough terrain, and fear.
How to fix it
Relax your legs. Seriously - that’s the primary fix. Bend your knees, loosen your ankles, let the wheel do its job. If relaxing feels impossible in the moment, initiate a gentle carve (controlled weaving) to break the oscillation pattern.
Do not jump off at speed. Ride it out, decelerate smoothly.
555 take
Every rider gets wobbles. The ones who crash are the ones who panic and stiffen up. Practice riding with relaxed legs at lower speeds first. When wobbles come at higher speeds, your body will know what to do.
