Alpha Platinum Lowstep Frame

This chassis utilizes high-performance aluminum hydroforming to house the internal battery while maintaining a very low entry point for accessibility. The low-step geometry allows for quick stops and secure mounting for riders of all mobility levels in heavy city traffic. Internal cable routing maintains a tidy aesthetic while providing the high stability required to handle the torque of the mid-drive Bosch motor system.

SR Suntour Trail Suspension

The front end features an NVX32 fork that provides 63mm of travel to absorb large impacts from curbs and uneven pavement expansion joints. This coil-spring suspension system includes a preload adjuster to customize the damping response based on your weight or the cargo carried on the integrated rack. It significantly increases ride comfort, ensuring that afternoon trips through the urban grid or park paths remain enjoyable for your body.

Shimano Hydraulic Disc Brakes

Stopping power is handled by a dual-piston system paired with 180mm rotors for superior force and safety in varied urban terrain. These MT200 hydraulic brakes deliver consistent performance in both wet and dry conditions, providing a significant safety upgrade. The system provides excellent modulation, allowing for smooth and controlled deceleration during high-speed fitness rides or heavy grocery transport.

Bontrager Kovee Alloy Rims

The wheelset features double-wall Kovee rims designed to withstand the torque and weight of a powerful all-road e-bike system. Having 32 stainless steel spokes ensures the wheel build stays true even when frequently hitting expansion joints or rough pavement at speed. These rims provide a durable rolling foundation that supports the additional weight of the battery and drive system during daily transit.

Schwalbe Smart Sam Tires

At 2.25 inches wide, these tires act as a versatile foundation with a tread pattern optimized for efficiency and multi-surface traction.
