How to Adjust Radio Flyer Tricycle: Assembly Steps

Steps for Assembling a Radio Flyer Tricycle

When I saw the instructions to assemble the Radio Flyer tricycle, I was at a loss. It is full of pictures without much-written instruction. If you are facing a similar issue, this guide will help you.

After you are ready with the parts and tools, follow the steps below to adjust the Radio Flyer tricycle:

Step 1: Attach the Rear Wheels

First, start with installing the rear wheels. Most Radio Flyer tricycles have two rear wheels that you need to attach. If there are any caps on the end of the rear axle, remove them and attach the wheels to the frame.

Then use a wrench and screwdriver to fasten the wheels. Do not tighten any nuts and screws, or else it will damage them. After attaching the rear wheels, move on to the front wheels.

Step 2: Attach the Front Wheel

In this step, you'll need to align the front fork with the front wheel axle. Then insert the axle through the fork and wheel. Once the axle is in place, you can tighten the nuts using a wrench and pliers to secure the wheel in place.

Some of the Radio Flyer's front wheels come with pedals attached to them. You won't need to install them separately if yours has the same feature; however, if not, you can do that later.

Step 3: Install the Handlebars

Now, take the handlebar and insert it into the stem. Then align the stem with the fork. Make sure it's straight; otherwise, your child may have trouble navigating.

While installing the handlebar, ensure that the bottom of the clamp is flush with the bottom of the stem. Use the Allen wrench to secure the handlebar in place.

Step 4: Install the Seat

Install the Seat

Now, you can move on to installing the seat. Mount the seat post on the seat tube and adjust its position as per your requirements. Then insert the nuts and tighten them with the wrench and the screwdriver.

Step 5: Install the Pedals

Install the pedal's wheels right away if they aren't already there. Identify the right and left pedals and insert them into the correct crank arms. Then again, secure them with a wrench. With this, the primary assembly of the Radio Flyer tricycle is over.

Step 6: Check All Connections

Lastly, check all the connections, nuts, and bolts to ensure they are secured. If you do not check them, it will be unsafe for your baby to ride the tricycle. Besides, apply grease to the pedal and handlebar, and other moving parts for a smooth operation.

Once you are done with the checking, you can put your baby on it and let them play.
