We’re excited to announce that the V7i is now available in Fog Grey—a fresh new color inspired by the California coast. ⁠ ⁠ As a California-based brand, we are inspired by the surrounding landscape. Spring and summer here bring dramatic shifts in weather, especially between the microclimates that define the region. Early morning fog is a familiar sight along the coast and just inland.⁠ ⁠ We’ll be posting about more new colors over the next few days, so stay tuned.⁠ ⁠ ⁠All new colors are currently available on our site if you don't want to wait to see them here. V7i Fog Grey, C7 24" Sage and R18 Disc in Mustard. ⁠ ⁠ Happy Friday. ⁠ ⁠ Photo by @lalifish⁠ ⁠ #publicbikes

We designed the R18 Disc to deliver a quick, responsive, and comfortable urban riding experience. Its lightweight steel frame offers a smooth, compliant feel on the road, while a slightly forward riding position enhances control and engagement. Paired with the modulation and confidence of disc brakes, the R18 Disc is confident in any urban environment. It's truly a bike that makes every ride enjoyable.⁠ ⁠ ⁠ #publicbikes
