Wheel Size: 27.5"

Before you buy this bike

You should verify that your local bike shop or your own tools can handle 27.5-inch wheels and standard 21-speed components. This ensures easy repairs and part swaps later. The carbon steel frame is durable but heavier than aluminum or carbon options. At 39.5 pounds, it is best suited for paved roads, light trails, and daily commuting rather than aggressive mountain biking.

It sits alongside other entry-level steel bikes in the market, offering similar specs but with a distinct weight profile. Consider your typical terrain before deciding. If you mostly ride on pavement, this model works well. For rocky trails, you might want a lighter frame with suspension.
