Strong construction, high-torque battery power, and advanced components, including a 7-speed gear range and an integrated brake light, add great value to this unique €1.599 foldable ebike.

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.
