Step-Thru to Adventure
We built the RadRhino to go anywhere and do anything. Now, it’s designed to fit anyone. Introducing the RadRhino Step-Thru, a low-step electric fat bike that combines the rugged look and capabilities of our flagship model with a new frame style that meets the needs of all riders. With a lower standover height and less distance between you and the handlebar, the RadRhino Step-Thru makes it easier than ever to get on and get going.
Made from a layer of aramid and ceramic particles inside the tire under the tread, the Kenda K-Shield integrated tire liner is a line of defense designed to provide extra protection against punctures from thorns, glass, and other small materials.

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.
