Installation & Adjustment 2.Installation and Adjustment 2.1 Handlebar and Stem Assembly Lift the handlebars/stem and align the stem with the head tube. Slide the stem onto the head tube and tighten the bolt at the top of the stem with a 5mm hex. To adjust the angle of the stem use a 5mm allen wrench to loosen the two side bolts, then loosen the wedge bolt. Adjust the stem to your desired angle and then tighten the wedge bolt followed by the side bolts.
Installation & Adjustment 2.Installation and Adjustment 2.2 Assembly of the Pedals Identify your pedals: check the letters on the pedals, “L” or “R”. The “R” marked pedal is for the right (when facing the forward direction). For attachment to the crank, tighten clockwise. The “L” marked pedal is for the left. For attachment, tighten counterclockwise when facing directly. WARNING First screw on the pedals by hand, then tighten with the wrench provided.
Installation & Adjustment 2.Installation and Adjustment 2.3 Seat Position To enable comfortable, fatigue-free and safe riding, the saddle and handlebar height should be adjusted to the body size of the rider. The saddle height is correct if the leg is near full extension while the foot is resting flat on the pedal in the bottom position of the crank cycle. The toes must still be able to touch the ground comfortably.
Installation & Adjustment 2.Installation and Adjustment 2.4 Saddle Height The quick-release lever must require noticeable effort to put into fully closed position to prevent any undesired movement while riding. WARNING An improperly closed quick release lever can open again or have limited ability to keep the saddle in place. This may cause the saddle to suddenly drop into the seat tube, potentially leading to serious falls and injury.
