GoKawiilXtracycle debuts $4,500 Swoop ASM cargo e-bike with Shimano's automatic shifting
Xtracycle has released the Swoop ASM, a long-tail cargo e-bike priced at $4,500 that uses a Shimano system capable of automatically choosing and executing gear shifts based on cadence, torque, and speed data. The bike also features a mullet wheel setup, with a larger front tire and smaller rear wheel, plus front suspension for a smoother ride.
GoKawiil's interpretation of the reporting above, not reported fact.
Automatic shifting removes a common pain point for e-bike riders who must otherwise guess the right gear as motor assistance changes power delivery in real time. While the tested system correctly identifies when to shift, its execution is still imperfect, showing that automation in bike drivetrains is promising but not yet seamless, and riders retain the option to disable it and rely on the bike's strong cargo-hauling design instead.
- The Swoop ASM costs $4,500 and integrates a Shimano automatic shifting system reacting to rider cadence and torque.
- The auto-shift feature can accurately determine optimal gear timing but performs shifts less smoothly than manual control.
- Riders can disable the automatic shifting, revealing a well-designed cargo bike with a mullet wheel setup and front suspension.
