AIMA Big Sur U Cargo E-Bike. 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, prioritizing 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.

Built for Two. AIMA designed the Big Sur U as a true two-person mover; a utility bike that comes fully outfitted with a passenger setup so you can comfortably bring a plus-one.

Built with a welded rear rack, a padded cushion, wheel guard, and foot pegs so you can transport a second rider with confidence. The 750W hub motor supports the added payload with ease and can switch between a natural torque-based feel or a more relaxed cadence-based one. You can fine-tune the responsiveness inside the Bafang Go+ app to match how lively you want the ride to be.

AIMA added several helpful features that make two-up riding simpler: shorter-diameter, wide-base 20×3.5” tires with a hybrid tread, oversized hydraulic brakes with 203mm rotors, and the stable handling that comes from BMX-style handlebars. The bike also covers safety nicely. You get turn-by-turn navigation on the TFT display, integrated lights, turn signals, and a horn for riding in traffic.

Features

MOTOR - 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 Power Assist. The torque sensor instantly reads your pedaling and adjusts motor output for seamless, natural assistance every time you ride.

Large Display Never Misses 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.
