The gyroscope effect is mostly negligible and is not in any way what makes a bicycle stable. They have built bikes with counterrotating flywheels that zero out the gyroscope effect and they're still perfectly rideable.
What makes racing bikes squirrelly is the short wheelbase and the low caster angle on the front wheel. This also makes them extremely responsive for steering, but that also means twitchy.
