A whole new perspective
Your own display. Set modes, brakes and acceleration your way.







Meet the ONSRA BLACK Carve 4—our most advanced electric longboard. A premium bamboo deck balances flex, comfort and control; the Gear Drive system adds instant torque, quiet power delivery and low-maintenance performance.
Powered by a 14S3P Samsung 50S battery (51.8V, 15Ah, 777Wh), it accelerates hard, climbs steep hills and stays planted whether you are carving mountain roads, commuting or chasing top speed. Smooth where it matters, aggressive when you want it—this is the BLACK Carve 4 we always wanted to build.
