Versatile Commuter Bike Promises Urban Adventure
Marin Bikes has introduced an exciting update to its popular Muirwoods commuter line, replacing the traditional 700c wheels with nimble 27.5-inch wheels designed to transform daily commuting into an urban adventure. The California-based brand, better known for its mountain bikes, continues to expand its affordable urban bicycle collection with this versatile new offering.
According to Marin’s product description, “With robust 27.5-inch wheels and 2.35-inch fast-rolling tires, you can hop off curbs, cruise down steps, duck into a skatepark on your way to work, or whatever else you dream up.” This bold statement positions the new Muirwoods as anything but a conventional commuter bike, appealing to riders who seek fun in their daily transportation.

Maintaining Classic Design with Modern Updates
The new 27.5-inch Muirwoods retains the classic silhouette of its larger-wheeled sibling while offering enhanced maneuverability. Constructed from 4130 chromoly steel that Marin describes as “smoothly butted chromoly,” the frame maintains the brand’s reputation for durable, comfortable riding characteristics.
The bike’s design accommodates tires up to 2.8 inches wide, providing ample room for riders to customize their setup based on terrain preferences. True to Marin’s practical approach, the frame and fork feature numerous mounting points for water bottles, accessories, fenders, and racks, making it ready for whatever cargo needs accompany a daily commute.

Balanced Geometry for Mixed Terrain
Marin maintains identical geometry between the 27.5-inch model and the 700c version, creating a predictable riding experience for those familiar with the brand. The 67.5-degree head tube angle provides slightly quicker handling than many dedicated commuter bikes while remaining stable for urban navigation.
The geometry and flat bar setup promote a natural riding position that works equally well for city streets and park trail detours on the way home. Available in sizes from S to XL, the bike accommodates a wide range of riders seeking a comfortable, upright position for daily use.
Competitive Specs at Approachable Price
The Muirwoods 27.5 comes in a single configuration priced at $949, offering substantial value for a chromoly steel bike with quality components. Key features include:
- Drivetrain: MicroShift Advent X 10-speed trail groupset
- Brakes: Tektro M274 hydraulic disc brakes with 160mm rotors
- Wheels: Marin aluminum alloy wheelset
- Tires: Vee Tire GPVee, 27.5-inch × 2.35-inch
This specification package provides reliable stopping power and gearing range suitable for both urban hills and recreational trail use. The Advent X drivetrain offers wide gear range with its robust clutch mechanism, while the hydraulic disc brakes ensure consistent stopping in all weather conditions.

Currently available only in a distinctive shiny gold colorway, the Muirwoods 27.5 brings both style and substance to the urban cycling scene. Marin’s latest offering demonstrates how commuter bikes can evolve beyond basic transportation to become sources of daily joy and exploration.
