In bikes, speed wobble starts when something causes the front wheel to accelerate to one side. … When shimmy does occur, it’s a case of the bike-and-rider system oscillating at its “resonant frequency” — the system’s natural frequency of oscillation, as determined by the physical parameters of that system.
Why does my bike handle shake?
During the wobbling stage, you will notice that the front wheel wiggles and the handle bar shakes vigorously. … Wobbling can be caused due to many factors, such as improper alignment of the wheel where there is a change in the castor or camber angle.

Why does my front bike tire wobble?
The balance between these two sides is what keeps your wheel true and prevents wobble. So, if your wheel wobbles to the left, that means the spokes on the right side are too loose to keep things balanced, or the spokes on the left are too tight.
Why does speed wobble happen?
Wobble or shimmy begins when some otherwise minor irregularity accelerates the wheel to one side. … As the wheel rotates, it will exert a cyclic load to the vehicle frame, which if matched with the system’s (vehicle and attached accessories) resonant frequency, can produce a speed wobble.
Why does my longboard wobble at high speeds?
Speed wobbles are caused from riding downhill too stiff. Just be sure to stay relaxed, and let the road take you. Therefore, skate within your limits first, then progressively attack bigger hills. It all comes with practice, as with anything.

Why does my motorcycle wobble at high speeds?
Wheel bearings — If the bearings get worn out, this could cause lateral axle movement which leads to wobbling. … Lateral axle movement — When the front or back wheel has excessive side to side or lateral axle movement, the bike will wobble. The issue could stem from worn wheel bearings or another problem.
