How to Attach a Child Bike to an Adult Bike

Updated July 20, 2017

Falling off your first bike as a child can result in more than just physical scrapes. Get your child confident about riding a bike by using a manufactured tow bar to connect your bike to your child's bike. You can use the tow bar to attach your child's bike on a day bike in the outdoors or for a quick trip to the grocery store. There are several companies that specialise in making biking tow bars for adult-to-child bikes. It is best to use these products since these manufactured tow bars have been tested and certified for safety.

Detach the bike seat from the adult bike with an adjustable wrench if necessary. Insert the bike seat into the loose hole at the end of the tow bar. Insert the bike seat with attached tow bar back into the body of the bike.

Tighten the bike seat, so that the seat is several inches above the tow trailer bar, with the adjustable wrench. Use the wrench to tighten the tow bar hole's screws or latches at the site of the bike seat if needed or available. Ensure that any security screws or latches are used so that the bike seat stays firmly attached in its position.

Lengthen or shorten the tow bar, depending on the length of distance you want between the child's bike and the adult bike. Use the appropriate lengths that the manufacturing company suggests in its owner's manual. The length will ensure that the adult and child bike tires do not touch.

Assemble the mounting clamp on the child's bike with adjustable wrench, torque wrench and socket wrench if needed. Place the mounting clip below the joint where the handle bars join the body of the bike. This clip will allow you to quickly release and attach the tow bar from the adult bike to the child's bike.

Attach the tow bar to the mounting clip on the child's bike. Detach the front wheel with the adjustable wrench from the child's bike if the wheel touches the ground after installation. Double check all screws, bolts and joints on the tow bar to make sure everything is secure.


The best spot to place the mounting clip on the child's bike depends on the weight of the child. The general advice is the heavier the child, the lower you place the mounting clip on the bar below the handlebars. Verify this with the instruction manual, since the exact placement measurements vary from manufacturer to manufacturer.
