About This Model
The AIMA Big Sur Sport is built for riders who like the stability, comfort, and confident traction of a fat-tire e-bike but prefer a more compact bike than a traditional 26-inch fat-tire model. Its 20-inch wheels keep the bike feeling approachable and maneuverable, while the wide 4-inch tires, upright comfort setup, and suspension fork help smooth out rough pavement, gravel, and uneven riding surfaces.

Power comes from a 750W Bafang rear hub motor paired with a torque sensor. Instead of simply turning the motor on when the pedals move, the torque sensor responds to how firmly you pedal, creating assistance that feels smoother and more connected to your effort. Riders can choose from five pedal-assist levels or use the throttle when they want power without pedaling.
The removable 48V 15Ah battery uses LG 21700 cells and provides a stated range of 30 to 60 miles, depending on conditions and assist use. AIMA also equips the Big Sur Sport with Tektro hydraulic disc brakes and large 203mm rotors, an 80mm suspension fork, a Shimano 7-speed drivetrain, full fenders, and an MIK HD rear rack. AIMA sells its e-bikes through authorized local dealers, so the bike can be professionally assembled, test ridden, and supported after the sale.
