KHS x Sillykids Bug S: The Professional Utility Cargo E-Bike
Engineered for the Modern Workforce and Active Pet Parents
The Bug S is a masterclass in utility-driven engineering, born from the collaboration between KHS Bicycles’ industrial manufacturing and Sillykids’ innovative urban vision. Designed to solve the challenges of “Last-Mile” logistics and urban pet transport, the Bug S is a cargo e-bike that combines a heavy-duty chassis with a compact 16-inch wheel profile for unmatched stability and cargo management.

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.
