The seat height is adjusted by replacing:
- Length of front fork
- Position of castor wheel in fork
- Size of castor wheel
and
- Rear axle bracket
- Rear wheel position
- Size of rear wheel
The seat angle is always 4°, so to ensure
that the castor bracket is always vertical to the
ground surface, the front and rear seat height
must be adjusted parallel.
