Why do controlled handlebar nudges help balance a slow bicycle better than holding the bars rigid?
Show answer & explanation
Answer: They move tire support
They freeze the lean angle — No. A bicycle does not balance by freezing the lean angle. The benchmark review compares rider balance with moving a support point under an inverted stick, and Cornell describes recovery as steering the wheels back under the bike. Holding the bars rigid removes one of the main ways to move that support.
They move tire support ✓ — Correct. Steering changes where the tires support the bike relative to the falling center of mass. The benchmark review uses the inverted-stick analogy: move the support toward the lean. Cornell's riderless-bike summary describes the same rescue in bicycle form, with the handlebars turning into the fall and the bike straightening.
They use gyroscopic help — Plausible, but not the mechanism asked about here. Gyroscopic effects can be part of bicycle stability, yet the support-moving sources point to a different rescue pattern: steer so the wheels return under the bike. Controlled bar nudges are steering control, not mainly a way to borrow wheel-gyro help.
