The AIMA Big Sur Sport 2.0 is the nimble, compact counterpart to the full-sized Big Sur 2.0, offering the same heavy-duty power in a more agile package. It shares the powerful 750W Bafang motor (1200W peak) with 85 Nm of torque, but swaps the 26" wheels for 20" x 4.0" fat tires to create a punchier, more responsive ride. Equipped with a high-capacity 48V 20Ah (960Wh) battery, it provides an impressive range of up to 75-80 miles. The Sport 2.0 features Tektro hydraulic disc brakes with 203mm rotors, a ZOOM suspension fork, and a Shimano 7-speed drivetrain. Tech highlights include a 4.0” Bafang TFT display with Bluetooth for on-screen navigation and notifications, integrated turn signals, and a customizable pedal sensor that allows riders to toggle between torque and cadence modes. Weighing in at 77 lbs, it maintains a 400 lb payload capacity, making it a versatile option for riders seeking big power in a smaller, more maneuverable frame.
