2. Setup and Assembly
Your AVASTA Bacchus BMX bicycle is shipped 85% pre-assembled. The front wheel, handlebars, pedals, and saddle require customer assembly. A dedicated tool kit is included to assist with assembly and adjustments. Please note that additional tools not included in the kit may be necessary for certain tasks.
Assembly Steps
- Unpacking: Carefully remove all components from the packaging.
- Front Wheel Installation: Attach the front wheel to the fork. Ensure it is centered and securely fastened.
- Handlebar Attachment: Install the handlebars onto the stem. Adjust the angle and tighten the bolts firmly.
- Pedal Installation: Identify the left (L) and right (R) pedals. Thread the pedals into the crank arms. Remember that the left pedal threads counter-clockwise. Tighten securely.
- Saddle and Seat Post: Insert the seat post into the frame and attach the saddle. Adjust the height to a comfortable riding position and tighten the quick-release or bolt.
- Brake Installation and Adjustment: The front and rear U-brakes are included. You can choose to install them for street riding safety or ride without them for pure BMX performance. If installing, ensure the brake cables are routed correctly and the brake pads align with the wheel rims. Initial fine-tuning of the brakes may be required.

4. Maintenance
Regular maintenance is crucial for the longevity and safe operation of your AVASTA Bacchus BMX. A dedicated tool kit is provided for basic adjustments and maintenance.
Routine Checks and Maintenance

- Frame and Fork: Inspect the high-carbon steel frame and fork for any signs of damage, cracks, or bends, especially after impacts.
- Crank System: The 3-piece crank system is designed for durability. However, regularly check for any looseness or unusual play.
