Australia's Clandestine Design Group revealed the Cellcius C-01, an electric motorcycle concept with eight removable hexagonal batteries. Each 10kg module holds 3kWh, letting riders cut weight from 220 to 160kg by carrying just two for short trips; empty slots become luggage storage. Fully equipped, it offers 24kWh and a theoretical 350km range. The batteries also function as portable power stations, while a shaft drive and claimed 195hp complete the design. Production remains unconfirmed.
