The Super73 S2 Electric Bike is a high performance electric motorbike designed for the urban adventurer, built with an aircraft-grade aluminum alloy frame and a fully adjustable air spring suspension fork. The S2 does not require a license, insurance, or registration. All bikes come with a battery that you can easily charge with any standard 110v outlet. On this model, the battery is removable with a key, making it easy to charge both at home and in-between rides. The BDGR is the first tire that blends motorcycle and bicycle tire construction methods to meet the needs of this revolutionary vehicle. Improve traction, reduce road noise, and increase stability for both on-road and light-duty off-road riding.
