Positives of The 6KU Fixie
Let’s start with the positives.
The bike is affordable, practical, and provides one of the best warranties you’ll find.
It’s also decently comfortable if you know how to adjust your bike properly to fit your proportions. Supple hand grips and a synthetic leather saddle provide all the padding you need even for longer rides.
A flip-flop hub lets switch from riding fixed and single-speed.
If you’re weight conscious, the 6KU weighs less the comparable fixies in its class.
Although its light it doesn’t skimp on durability, at least for the quality of components you get on a budget bike. You get Deep V double wall wheels which can really take a beating.

The 6KU Aluminum Fixed Gear Review
Would I call the 6KU a beautiful bike? Not beautiful, but practical. A real work horse.
It’s also incredible how cheap this fixie is without skimping on quality. You can get it in every size from 47 cm. To 61 cm., meaning almost any rider can find one that fits.
The bike is affordable and available in all sizes, making it one of the most practical all-purpose bikes on the market.
If you’re not already familiar with fixies and single speeds this is a great starting bike. It will take you to class, the office, or the park with friends.
You won’t feel bad about riding it in the rain, plus thieves prefer to target more expensive bikes.
There’s no extra weight dragging you down, plus you can customize it as you see fit. Many 6KU riders run either single-speed or the fixed gear with just a front brake.
As a bonus, the 6KU looks pretty cool. Not bad for a few hundred bucks. Plus, if you buy it on Amazon you can get FREE shipping. Assembly requires only a few basic tools you could find at a local bike shop.
Specs & Features of The 6KU
Fixies/single-speeds offer a number of benefits you won’t find on road bikes or hybrids. Many riders choose fixies for the value and convenience these features provide. If you’re new to fixed gear, these will give you an idea of whether fixed gear is right for you.
Removing brakes is easy
Some people like to rely on pushing back on the pedals as their brake. You can use this mechanism to slow down even if you run a brake. Since the pedals serve as brakes of their own, some riders choose to take off one or both brakes to give the bike a slicker appearance and to reduce weight.
Single speed track bike with flip-flop hub
Easily change your set up from single-speed to fixie in just a few minutes. The 6KU comes with a flip-flop hub, so you can cater your bike to your ride by flipping the wheel around.
Maybe you want to try some tricks or skids, so you ride it as a fixie. When you’re done you can switch the wheel around to the freewheel side and take advantage of coasting to make a longer ride more comfortable.
6KU Aluminum Frame
This bike comes in two versions – steel and aluminum. Cyclists can go on for hours about the differences between the two, but here’s a concise breakdown.
Steel is heavier, but also softer and more durable. It can take more abuse. Aluminum is light and nimble, but it’s quite stiff and is more likely to crack when under extreme duress.
Ergonomic Grips, Saddle, & Seatpost
Comfort is critical for a cyclist. The 6KU delivers with a synthetic leather saddle that provides that comfort and gives the bike a sleek look for a low cost. Its seat post is a standard 27.2 mm, so you can switch out for another seat post conveniently. Plush grip handlebars provide not only tight control over your bike but a gentle grip for your hands.
Handlebars
The riser handlebars on this bike are popular on fixies. They’re narrow and give you the tight handling and leverage you need to be agile in city traffic. Even if you prefer a different handlebar, the stem is also standard size so upgrading later is easy.
Wheel Sets
The double-wall Deep V rims provide durability and cushioning without being too heavy. At 30 mm. they also won’t weigh you down at all, plus they’ll be compatible with standard tire valves.
700 x 25c tires are slightly wider than the narrowest road-bike tire, giving you that extra stability that can really come in handy in the city.
Customize Your Colour
Choose one of 5 different colours and accents to get the style you like. You can get classic white or black or something more vibrant, like red.
Is The 6KU Fixie Bike Easy To Build & Maintain?
You’ll be able to put the 6KU together with the tools that come in the box. It only takes a few minutes. Maintenance on fixies is famously low, but when you need a tune up this bike is a breeze.
Wide Choice Of Sizes
As mentioned above, if you’re between 4’10’’ and 6’5’’ the 6KU comes in a size for you. It’s available in everything from 49 cm – 58 cm. The aluminum model has a slightly broader range, though. Not sure about your size? There’s a sizing guide on the Amazon page or you can find one on Google.
