A single-speed bicycle is a type of bicycle with a single gear ratio. These bicycles are without derailleur gears, hub gearing, or other methods for varying the gear ratio of the bicycle. While most fixed-gear bicycles are technically single speed, the term single-speed generally refers to a single gear ratio bicycle with a freewheel mechanism to allow it to coast. { Great design } Sleak, trendy and Stylish MTB- Hashtag is built to conquer any road or trail with ease.
