26RU07 16"Folding bike

This small Bub 16-inch folding wheelset features a compact design, easily fitting into car trunks, subway turnstiles, or office corners, perfectly suited for multi-segment commuting needs. The 16-inch wheelset reduces rolling resistance and enhances pedaling efficiency, significantly minimizing road bumps and improving traction over manhole covers or potholes for a smoother daily ride.  This standard wheelset is the mainstream universal norm for folding bike rims, with a wide range of mature aftermarket accessories available—from lightweight carbon fiber wheels to tires of varying widths. It also directly accommodates upgrades for most Bub models, offering low modification thresholds and high playability.  Ideal for "subway + cycling" or "bus + short-haul" travel modes, it can be folded and carried directly into public transport, solving the last 1-5 km commute pain points. Suitable for urban commutes and leisure scenarios like city sightseeing or café visits, it stands as a popular choice for commuters seeking both practicality and photo-worthy appeal.
