5. Operating Instructions
5.1 Adjusting Seat and Handlebars
Proper adjustment of the seat and handlebars is crucial for comfort and effective training. The BH Vienna allows for both vertical and horizontal adjustments.
- Seat Height: Loosen the adjustment knob on the vertical seat post. Raise or lower the seat until your leg has a slight bend at the knee when the pedal is at its lowest point. Tighten the knob securely. The graduated markings on the post help in recalling your preferred setting.
- Seat Horizontal Position: Loosen the adjustment knob under the seat. Slide the seat forward or backward to achieve a comfortable position relative to the handlebars. Tighten the knob securely.
- Handlebar Height: Loosen the adjustment knob on the handlebar post. Raise or lower the handlebars to a comfortable height, typically level with or slightly higher than the seat for beginners, or lower for a more aggressive cycling posture. Tighten the knob securely.
