How to Attach a Baby Seat to a Bike

How to Attach a Baby Seat to a Bike
Baby seats let you take your child with you on your bike rides. There are different styles of baby seats to choose from: Some attach between your saddle and the handlebars; the most common seats attach to a rear rack, behind your saddle. These rear baby seats will come either as one piece, with the rack and carrier attached together, or the carrier will have the ability to slide on and off the rack. If you have trouble installing your baby seat, take it in to your local bike shop for help.


Difficulty: Moderate

Things You’ll Need:
  • Baby seat
  • Rack
  • Set of hex wrenches
Step 1
Bolt the top arms of the rack to the seatstay rack mounts on your bike. These holes should be close to your rear brakes. Use the appropriate size hex wrench and tighten the rack just enough so that the bolts stay in place. Keeping the bolts loose will make it easier to adjust the rack once you've also bolted down the bottom of the rack.
Step 2
Bolt the base rack strut to your bike. The eyelets for the bolts will be close to the rear dropouts on your bike. Using a hex wrench, tighten the bolts just enough to catch the threads.
Step 3
Straighten the rack. Look at the rack from the side and make sure it sits parallel to the ground. It's not safe to attach a baby seat to a rack that leans either forward or backward. Because you left the bolts loose, the rack will move easily, so you can adjust it to the right position.
Step 4
Tighten all the bolts to securely attach the rack to your bike. Start with the bolts of the base struts. Snug the bolts down, making sure not to shift the rack out of position. Tighten the bolts on the top arms next. Use the appropriate size hex wrench and secure all bolts tightly.
Step 5
Attach the baby seat to the rack. Some baby seats come designed to slide on the rack they came with and click into place by a mechanism that doesn't require any further assembly. With these baby seats, make sure the child carrier fits into place and snaps on completely. Shake the seat to make sure it is attached securely.

Tips & Warnings

Always follow the directions in the user's guide for your specific baby seat.
