RadWagon™ 4 Electric Cargo Bike

Overview Safety & Quality Specs & Details Reviews

Holds the kiddos. Plus groceries.

This next-level hauler is perfect for taking the kids across town or loading up at the hardware store. The electric cargo bike's elongated frame and lower center of gravity provide stable, reliable rides, even when you’re taking full advantage of the 350 lb. payload capacity. Take a passenger (or two!) for a spin. Our family-friendly accessories get the whole gang outside.

Each Piece Intentionally Designed for a Purpose

Built to share

Whose turn is it to take the kids? Either way, the ecargo bike’s adjustable handlebar and telescoping seat posts let you quickly achieve a custom fit for either parent.

Master of the drop-off line

Maneuver easily - even when loaded up! Our in-house team of engineers kept a low center of gravity for balanced, stable rides.

Put the ‘go’ in ‘cargo’

Max out the RadWagon's impressive 350-lb. payload capacity by strapping on bulky items, attaching panniers, platforms, or baskets.

Your minivan may get jealous

Create the ebike setup ideal for you and your crew by adding a childseat, caboose, deckhand, running boards, and more.

You will not be able to ride the bike comfortably.

You will be able to pedal and stand over the frame comfortably.

Your legs may be too long to get full leg extension when pedaling.

What to Measure

Your “bike inseam” — or inside leg length — is the distance between your body where it sits on your bike saddle and the ground.

It’s typically an inch or two longer than the length of your trousers, but measure to be sure.

You’ll use this number on the chart to get a feel for how the different models will fit you.

How to Measure

Gather the tools needed:

Medium-width hardcover book
Tape measure
A wall you can stand against
A trusted friend or relative

Wearing your regular riding shoes and with your back to the wall, stand with your feet spread so there is about 7 inches between them - this is about the distance apart your feet would be when straddling a bike with your feet on the ground (standover height).

Place a hardcover book against the wall with the spine of the book facing upward. Slide the book upwards towards your groin until it is solidly against your body. This may be a bit awkward, but is way more comfortable — and safer! — than trying to ride a bike that is too big.

If you have a buddy helping you, get them to measure from the floor to the top of the book spine while you hold the book in place. If you’re going it alone, carefully hold the book in place and measure from the ground to the top of the book spine.
