3.Assemble the base rails. Diagram 3. While your assistant holds the upright supports, slide the seat bracket under the base rails and align the mounting holes. Place the alignment bracket into position between the base rails and align the holes.
4.Secure the base rails. Four fasteners secure the seat bracket. A pair of fasteners with long bolts is inserted through the side (horizontally) and another pair of fasteners are inserted (vertically) through the base of the seat bracket and into the base rails. (Note that the vertical fasteners are not shown in Diagram 3.) To secure the base rails, take the following steps:
a.Insert the long bolts and washers (horizontally) through the seat bracket, base rails, and alignment bracket. Diagram 3.
b.Place a washer and locknut onto the ends of the bolts and finger tighten.
c.Place a lock washer and washer on each of the two shorter bolts. The lock washer should be placed against the head of the bolt.
d.Align the bolt holes and insert the bolts (vertically) through the seat bracket and base rails. Finger tighten the bolts.
5.Position the handlebar over the upright supports. Diagram 4. Slide the handlebar into place and align the bolt holes. Be sure that the wrist straps, on the handlebars, face toward the rear (seat assembly location).
6.Insert the bolts (with washers) through the upright supports and into the handlebars. Diagram 4. Notice that there are two bolt holes in front and two in back. Finger tighten each bolt. Do not use the hex key at this time. Loose bolts make it easier to install the seat frame.
