Step 2: Attach Seat Rails

Position the frame on a stable surface and align the seat rails with the designated mounting holes on the bike’s frame. Use the supplied Allen key to tighten the mounting screws evenly, ensuring the rails sit flush against the frame. Apply a light coat of anti‑rust grease to the screw threads before insertion to prevent corrosion and ease future adjustments. Once the rails are secured, adjust the seat height by sliding the rails up or down along the vertical track until the desired height is achieved. Lock the rails in place by tightening the seat clamp bolts, rotating each bolt clockwise until the seat is firmly held. Verify that the seat is level by placing a small tool or a level indicator on the seat surface; any tilt can affect pedal alignment and rider comfort. After securing the seat rails, inspect the entire assembly for any loose components or misaligned parts. Tighten any loose screws and ensure that the seat rails do not wobble when pressed. This step ensures a stable and safe seating position, which is critical for effective resistance training and injury prevention during workouts. For optimal performance, periodically recheck the seat rail tension and adjust as needed. The seat rails should remain firmly attached even during high‑intensity sessions, providing a reliable base for the rider’s posture and pedal motion. This completes the attachment of the seat rails, preparing the bike for the next assembly stage. The seat rails are designed to accommodate a wide range of users, ensuring that each rider can find a comfortable and ergonomic position that promotes proper posture and reduces strain on the lower back during extended sessions. Regular maintenance of the seat rails, such as cleaning the contact points and checking for wear, helps extend the lifespan of the bike and ensures consistent performance over time.
Step 3: Secure Pedal Assembly
Begin by locating the pedal attachment points on the frame’s horizontal arm. Each pedal is secured with a 10‑mm hex socket head cap screw. Use the supplied Allen key to loosen any existing screws, then slide the new pedal into place. Ensure the pedal’s alignment: the footrest should position the knee slightly bent when the foot is at the bottom of the stroke. Tighten the screws clockwise until the pedal feels firm, but avoid overtightening which could strip threads or damage the frame. After both pedals are in position, double‑check the torque by gently rocking each pedal; it should not move more than 1‑2 mm. Attach the pedal straps by sliding the strap through the designated loop, adjusting the length so it sits snugly around the ankle without cutting circulation. Secure the strap by tightening the buckle or lock mechanism, ensuring it is not twisted. Test pedal rotation by spinning each pedal manually; the motion should be smooth and free of resistance, indicating proper tightening. If resistance is felt, re‑tighten the screws or adjust strap tension. Perform a quick safety check: stand beside the bike, place a hand on the frame, and gently push the pedals to confirm stability and that the frame does not wobble. This completes the pedal assembly step, ensuring a safe and comfortable riding experience. Ensure the pedal axle is at least 2 cm clear from the frame at the 3 o’clock and 9 o’clock positions, and apply a drop of grease to the bearing housing for rotation.!!!??!!!!!.

Adjusting Position
