Let Us Do the Heavy Lifting

It’s the strongest and most versatile version of the RadWagon yet, featuring smaller, innovative new tires developed by our in-house team of expert engineers to achieve a lower center of gravity. Its patent-pending new frame design ensures multiple points of adjustability, including a telescopic seat post and easily maneuverable handlebars.

This is a next-level hauler designed for those who are loading up to go somewhere, whether that’s taking the kids on a trip across town or a weekend visit to the hardware store or farmer’s market. With a standover height 2.4 inches lower than its predecessor and a 500W geared hub motor, the RadWagon 4 is in it for the long haul.

What to Measure


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


This will typically be an inch or two longer than the length of your trousers, but you’ll want to 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:

  1. Medium-width hardcover book
  2. Tape measure
  3. A wall you can stand against
  4. 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.

Rad Battery Pack

The Rad Battery Pack

With over a decade of designing and building ebikes under our belts, we know that a high-capacity battery like this isn’t something you cheap out on. We designed and built our batteries using genuine Samsung 35E cells, which are some of the most energy-dense and reliable lithium-ion cells on the market today. These cells have allowed us to build an overall better battery, and at only 3.5 kg, it's one of the lightest and most energy-dense packs on any electric bike.

Powerful, Effective Geared Hub Motor

For the first time ever, the RadWagon now features a geared hub motor, which provides twice the torque compared to the direct drive motor used in previous models. This motor, which can be found on several of our off-road and utility-oriented models, offers improved uphill hauling and helps riders quickly get up to speed from a stop. Whatever your ride calls for, you can complete your mission in confidence — even with up to 158 kg of cargo.
