Daymak, the Canadian manufacturer of the Beast solar scooter intoduced its Daymak Drive System (DDS) at Interbike 2014 . It is an e-bike conversion kit, and the wheel is designed to fit most bicycles. A handlebar-installed throttle communicates with the hub wirelessly. All display functions and management are displayed via a Bluetooth phone application.
The 250-watt motor, the 36-volt/12-Ah lithium polymer battery and the 15W/hr solar panels are contained in the wheel’s hub. One hour of sunlight should provide enough power to the battery for 0.6 miles (1 km). The battery can also be charged through a charger.
The DDS should be available in 2015 in 26-inches and 28-inches wheel sizes at a price of $699.
