Because of the gyroscoptic precession of that big, heavy front wheel, this tilts the bike, and it is the tilt that does the actual turning. Humm. Bike going forward. Rotation vector of front wheel goes right to left (using right-handed axis system). Push left handlebar forwards. Front of rotation vector moves forwards. Precession vector is change in rotation vector: front to back. Which is a roll to the right. In other words, the affect of precession would roll in the direction of steer. Ian |
