Riding bicycles is a universal means of travel found in even the poorest communities throughout the world. For most families in the developed world, a bicycle is more about recreation than travel, and enjoying recreation activities with small children is one way to encourage them to engage in an active lifestyle into their adult years. Bell makes several versions of their classic child carrier seat. All of them install in essentially the same manner and can be done by anyone strong enough to lift the seat and use a wrench.
Locate and attach the two left and right underseat supports. These are the two bent pipe pieces came with the seat. Use four of the supplied 6-millimeter by 30-millimeter round head bolts, nuts and washers. Each support is stamped L for left and R for right. Install them underneath the carrier in the molded valleys in the seat bottom. Attach one bolt near the front and one at the rear of each support, pushing the roundhead bolt down through the top and fastening the nut underneath the seat, on the bottom of the support. Attach the long lower brackets that will extend down to the back-wheel bolt to the bottom ends of each seat support, with one 8-millimeter by 30-millimeter round head bolt. Place bolts with rounded heads facing out.
Remove the seat post bolt from your bicycle with two wrenches. This is the horizontal bolt directly under the seat on the pipe holding your seat. Slip the seat post U-bracket into place over the bike's seat post bracket and fit the replacement seat post 8-millimeter by 58-millimeter hex-head bolt through the bracket and seat post. Install and tighten the washer, nut and nut guard supplied to the end of the bolt. Position the seat so that the underseat supports fit over the U-bracket. Choose the hole from the five available that best positions the seat on your bike and install an 8-millimeter by 58-millimeter hex-head bolt through the seat support and bracket, fitting the spacer onto the bolt between the sides of the U-bolt. Fasten it with a washer, nut and nut cover and tighten.
Install two of the clear, plastic, flexible, paint protector sleeves that came with your seat over the ends of the lower brackets you installed on the bottom of the seat supports. Fit the remaining protectors over the short frame brackets, as well. Position the long lower brackets so that the slight hump in the bracket is aligned with the inside face of the lower frame bar, on either side of the rear wheel. Position a short frame bracket on the outside, fitting the notched tongue of the bracket into the slot on the end of the long, lower bracket, so that the frame bar is circled by the two pieces. Attach the small bracket at its top end, using one 8-millimeter by 30-millimeter roundhead bolt.
Place the seat cover on the seat, threading the Velcro straps through the lower vertical slots in the seat back. Fasten the Velcro straps together behind the seat back. Slip the plastic stop on the end of each seat strap through the top horizontal slot from the back of the seat, then through the second horizontal slot from the front of the seat. Pull the strap to set the stop against the back of the seat. Fit the stop on the center strap through the two horizontal slots in the bottom front of the seat in the same way. Install lap belt using same procedure through the slots you used for the Velcro straps on the seat pad.
