Built for the Gig Economy: The Ultimate Delivery Platform

For professional couriers and gig delivery riders, the Bug S offers a versatile, flat-loading ecosystem.

  • High-Payload Capacity: With a total system load rating of 200kg, the Bug S handles oversized delivery bags, thermal boxes, and heavy parcels without compromising frame integrity.

  • Modular Rack Integration: The frame is optimized for wide-base platforms and specialized front/rear racks, ensuring your cargo stays balanced and secure through tight city turns.

  • Lower Center of Gravity: The 16-inch wheel design keeps the weight of your delivery lower to the ground, significantly reducing “top-heavy” wobbling when fully loaded.

Premium Pet Transport: Safety in Every Mile

Bring your companions along with confidence. The Bug S isn’t just pet-friendly; it’s pet-engineered.

  • Low-Step Entry: The ultra-low stand-over height allows you to stabilize the bike easily while loading a pet carrier or trailer.

  • Trailer-Ready Chassis: The reinforced rear dropout is designed to accommodate heavy-duty pet trailers, allowing you to tow companions or gear weighing over 100kg with ease.

  • Vibration Dampening: The combination of a Cr-Mo steel fork and ultra-wide tires absorbs road chatter, providing a smoother, less stressful ride for pets in rear baskets or attached trailers.
