Refer to the owner's manual for safety warnings.
Step D: Handlebar Clamp
Secure the handlebar in the stem. Follow the numbered steps and use the appropriate tools. [Image shows securing the handlebar with bolts and a hex wrench.]
Step E: Handlebar Tightening Sequence
Tighten the handlebar bolts in a criss-cross pattern (1-3-2-4) to ensure even pressure. Rotate each bolt 180 degrees after initial tightening. Use a 4mm hex wrench. [Image shows the tightening sequence and 180-degree rotations.]
Step F: Final Handlebar Check
Visually inspect the handlebar clamp to ensure it is properly secured. [Image shows a visual inspection of the handlebar clamp.]
Step G: Torqueing Handlebar Bolts
Use a torque wrench to tighten the handlebar bolts to 5.2 Nm. Listen for the clicking sound of the torque wrench to confirm correct torque. Repeat the tightening sequence. [Image shows using a torque wrench and the specified torque value.]
Step H: Steering Adjustment
Adjust the steering by rotating the stem 360 degrees and then tightening the bolts with 180-degree turns. Use a 5mm hex wrench for the main bolt and a 4mm hex wrench for the side bolts. [Image shows steering adjustment steps.]
Step J: Final Steering Alignment Check
Ensure the handlebar is perfectly aligned with the front wheel after all adjustments. [Image shows a person checking the steering alignment.]
Step K: Final Torque Check
Perform a final torque check on the steering components, ensuring all bolts are tightened to 5.2 Nm. [Image shows using a torque wrench on steering components.]
Step L: Seat Post Adjustment
Adjust the seat post height by loosening the clamp and sliding it to the desired position. Tighten the clamp securely. [Image shows adjusting the seat post.]
Step M: Pedal Check
Ensure pedals are securely attached. Tighten with a 5mm hex wrench, rotating 180 degrees three times. [Image shows checking pedal security.]
Step N: Seat Height and Rider Fit
Adjust the seat height so the rider can comfortably place their feet flat on the ground with a slight bend in the knees. Check for proper foot placement and leg extension. [Image shows correct and incorrect rider fit.]
Step O: Saddle Check
Ensure the saddle is securely fastened and properly aligned. [Image shows a saddle check with a cross indicating incorrect mounting.]
Step P: Bike Flip Check
Perform a check after flipping the bike to ensure all components remain secure. [Image shows flipping the bike for inspection.]
Step Q: Rear Wheel Check
Check the rear wheel for proper attachment and security. Use a 15mm box wrench. [Image shows checking the rear wheel with a 15mm wrench.]
Step R: Front Wheel Check
Check the front wheel for proper attachment and security. Use a 4mm hex wrench. [Image shows checking the front wheel with a 4mm wrench.]
Step S: Pedal Tightness Check
Ensure the pedals are tight and secure. [Image shows checking pedal tightness.]
Step T: Tire Inflation
Inflate the tires to the recommended pressure: 35 P.S.I. (240 KPa) (2.4 BAR). Use a tire pump. [Image shows inflating tires.]
Step U: Pre-Ride Check (Stability)
Before riding, ensure the bike is stable. Check for any clunking or rattling noises, which may indicate loose parts. A drop test from 30cm (1 foot) can help identify instability. [Image shows a stability check.]
Step V: Pre-Ride Check (Steering)
Before riding, check the steering for smooth operation and ensure there are no loose parts. [Image shows checking steering operation.]
