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.
