Overview
About this bike
A lightweight sporty all around bike for commuting, fitness training, or longer excursions. Designed for a responsive ride, the Atlas comes with a lightweight aluminum frame, threadless stem and fork, powerful hand-operated linear pull brakes, quick-release wheels with alloy double-wall rims, 700 x 35c tires, and Shimano 21-speed gearing controlled with handlebar-mounted Revo twist shifters. Your dream bike if... Your route takes you anywhere from downtown to the coastline. You love seamless gear changes, lots of speed options, and hitting the perfect cadence. Most importantly, you want a comfortable, versatile bike for workout sprints or speeding at sunset. It's all in the details... Atlas sports Shimano Tourney front and 7S rear derailleurs to give you a wide range of gearing with smaller intervals of effort input. This allows you to get the exact pedaling feeling you're seeking with smoother transitions in between. Easily switch gears with at-your-fingertips Revoshift twist shifters. Plus, its threadless steering system lightens your load, gives less flex and more precision, and is much easier to maintain or adjust as needed. The cherry on top... Atlas' lightweight, aluminum step-through frame supports an upright riding position to reduce back strain while its sport saddle combines comfort with performance for the fitness-focused cyclist. Constructed with mostly alloy parts, this lightweight bike is perfect for speeding and sprinting across your city.
