AIMA E-Bike is proud to present the Big Sur, our first e-bike model. Inspired by the rugged terrain and sweeping vistas of California's Big Sur coastline, infused with a deep appreciation for the beauty of the natural world, and a commitment to cutting-edge engineering, crafted with meticulous attention to detail, AIMA E-Bike is designed in California and manufactured in the world's largest E-Mobility factory. We prioritize safety, performance, aesthetics, and integrity in every step of the manufacturing process, with a mission to deliver you the perfect companion for your next big ride.
Ride Further with Confidence
Enjoy up to 80 miles on a single charge thanks to the upgraded 48V 20Ah battery — that’s 33% more range than our 1st Gen.
Quieter, More Efficient Power
Compared to our already whisper-quiet first-generation motor, the new 750W version cuts noise by another 10dB while improving energy conversion—delivering the same quick, powerful acceleration with even greater efficiency.
Effortless, Natural Pedal Assist
The torque sensor instantly reads your pedaling and adjusts motor output for seamless, natural assistance every time you ride.
Never Miss a Turn... or a Call
The larger 4.0” display keeps stats clear at a glance, with FindMy and Bluetooth connection so you can mirror navigation, calls, and messages from your phone through app.
Built Like a Tank
A reinforced frame stands up to rough terrain and daily use, delivering long-term reliability in any riding environment.
Confident Braking Power
203mm hydraulic disc brakes provide strong, consistent stopping ability—even on steep hills or in wet conditions.
