Surly
used bikes for sale
Surly is an in-house brand development at Quality Bicycle Products, Minnesota base. The brand emerged somewhere in the mid 1990s and was quite popular for its single-speed bikes. During that time, “fatbikes” started gaining popularity for their use during the winter season. But they were considered quite expensive and exotic. Quality Bicycle Products wanted to standardize mass production thus, started manufacturing FatBikes under the Surly brand. In the 2010s, the brand became known for its fat tire bikes.
