Learn how to install the Radio Flyer Cubby Kit on your Flyer™ Loop eBike. This step-by-step guide covers mounting, wiring, and safety checks for a secure kid-carrying setup.

Quick answer

Installing the Cubby Kit on your Flyer™ Loop eBike takes about 30 minutes and requires basic tools. The kit mounts to the rear frame, and you'll need to connect the included taillight and turn signals for added visibility.

Before you start: what to know

The Cubby Kit is designed specifically for the Flyer™ Loop eBike, so it won't fit other models. Make sure your eBike is on a stable surface and the battery is removed before beginning.

You'll need a Phillips head screwdriver, a 4mm hex key, and a pair of wire cutters. The kit includes all mounting hardware and wiring, but you may want a small flashlight to see under the frame.

Installation steps

Remove the rear cargo platform: Using a 4mm hex key, unscrew the four bolts holding the existing rear platform to the frame. Lift the platform off and set it aside. Keep the bolts for later. Common mistake: losing the bolts. Place them in a small container or baggie.
Attach the mounting brackets: Align the Cubby Kit's mounting brackets with the frame holes where the platform was. Insert the bolts and tighten them firmly but don't overtighten. The brackets should sit flush against the frame. Checkpoint: ensure brackets are level before tightening fully.
Secure the Cubby Kit frame: Slide the Cubby Kit onto the brackets until it clicks into place. Use the provided screws to lock it in. Test for any wobble by gently pushing side to side. Empty
Connect the taillight and turn signals: Route the wiring harness along the frame to the rear of the kit. Plug the taillight and turn signal connectors into the matching ports on the eBike's battery housing. Use zip ties to secure loose cables. Common mistake: pinching wires under the frame. Route cables on top of the frame and secure with zip ties.
Test all lights: Reinstall the battery and turn on the eBike. Activate the headlight and check that the taillight illuminates. Test both turn signals by pressing the left and right buttons on the handlebar. Empty
Final safety check: With the kit installed, take a slow test ride in a safe area. Listen for rattles and verify that the lights remain visible. Adjust any loose connections or brackets as needed. Checkpoint: repeat this check after the first ride with kids to ensure everything stayed tight.

What you're installing

Cubby Kit: The Cubby Kit turns your Flyer™ Loop into a kid-ready cruiser with footboards, padded seats, and extended side rails to protect little fingers. The taillight and turn signals mount to the back for added visibility. This means you can safely carry up to two kids while keeping them secure and visible to traffic, making it a practical upgrade for family rides.
