The AIMA Big Sur U wasn’t what Harry Dacre pictured when he sang about Daisy Bell looking sweet upon a bicycle built for two, but I can assure you this bike is far more fun than anything he imagined. 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.
It ships 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 20x3.5” 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.
