Efficient Energy Transfer

One of the fundamental principles of riding a bicycle is energy transfer. As you pedal, the energy you put out is supposed to run the bike and not get wasted. With a fixed-gear bicycle as the 6KU, all the power you use in cycling generates forward motion. 

Since this bike only runs when it is peddled, you do not lose your energy coasting. Although it is designed for personal use, its energy efficiency makes it work like a racing bike, hence maximum performance and exhilarating speeds.

The 6KU Track Fixed Gear Bicycle comes with a durable, high-tensile steel frame that is able to support your weight and provide you with a frame that holds up in almost any condition it may face.

Flip-Flop Hub

If you are getting into the world of fixies for the first time, you should start with a crossover. The 6KU is the perfect beginner’s bike for this venture. The 6KU comes with a flip flop hub, which simply means that you get to shift between a fixed gear bike and a single-speed bike. 

On a freewheel gear, you can build up the momentum and eventually allow the bike to coast. On a fixed gear, you do not enjoy the luxury of coasting—any attempts at backpedaling result in an instant stop.

The 6KU bike offers both options for your convenience. By simply flipping the rear wheel position, you get to shift between the fixie and single-speed without a problem.

Lightweight and High Speed

You want a bike that will offer comfort and speed at the same time. The 6KU bike offers stability, durability, and, most importantly, ensures high speed. The light aluminum frame makes the bike a performance beast in every way. 

However, having a light frame does not mean the bike is weak. The 6KU is steady and strong and can be used in tough terrains. The frameset remains sturdy even at the highest speeds, making it a perfect choice for daily commuters.

Comfortable Handle and Convenient Handlebar Brakes

The other factor that counts when shopping for a bike is safety. The wide and low handles are well-positioned to provide control over the bike. With the brakes located right on the handlebars, you will not have a problem slowing your bike down.

While most fixed gear bikes lack handlebar brakes, this fixie offers riders an option of using either backpedal or the brakes. For novice riders of a fixed gear, this is a great bike to use when learning the ropes.

Easy to Assemble Tools

The other factor that stands out with the 6KU is the ease of assembly. The bike comes with a full set of tools and a guide to help you assemble. The easy-to-follow guide will help you assemble all the accessories in just a few hours, if not minutes.
