The Altera has more wattage (500W vs 250W), so it’s punchier off the line and excels in short bursts—ideal for shorter commutes.
The Lanes Prime makes up for that with consistent torque and refined responsiveness, especially noticeable on long climbs or when carrying extra cargo.
Frame Style & Accessibility
Prefer the convenience of a step-through design? The Kalosi Lanes Prime offers this as its standard.
For those seeking more options, the Kalosi Altera is available in both low-step and traditional high-step versions, providing greater flexibility to suit your preferred mounting style and overall comfort.
Drivetrain & Added Commuter Features
The Lanes Prime features an 11-speed Shimano CUES drivetrain, offering a broader gear range.
The Altera comes with a 9-speed Shimano CUES system. Both bikes include essential commuter-ready features like integrated lights, robust front/rear racks (Lanes Prime) or rear rack (Altera), and fenders to keep you clean on your journey.
