The Vigour+ is an electric bike with a hidden battery. It has a silent yet powerful Zehus motor. It is an intelligent lightweight e-bike weighting only 16 kg and it charges its battery when you brake. This trendy design e-bike also has a unique steel frame. You can customize the rest! The Vigour+ works with a special app. Simply select different power modes on your e-bike app to control the smart motor via Bluetooth connection. As you can expect of Roetz, every bike comes with a re-used steel frame and every Vigour+ is built by hand. High quality guaranteed.
