27-Inch Bike For What Size Person?
A 27-inch bike is suitable for an adult and exceptionally tall teenagers, but it doesn’t suit a kid or short riders. For example, an 8 years old child, 3’6″ tall, can not ride a 27-inch bike but can comfortably ride a 20-inch bike. Basically, a 27-inch bike is suitable for adults within the height range of 5’3″ to 6’6″.
For a more precise understanding, let me start with what a 27-inch bike is.
What Is A 27-Inch Bike?
When referring to a 27-inch bike, we are talking about a road bike whose wheels are 27 inches in size. People often mistake it for the frame size because road bikes means a 27-inch bike should be a frame size of 27 inches. Therefore, always remember that whenever we talk about a 27-inch bike, we address the wheel size, not the frame size.
27-inch bikes are called road bikes because they are used on smooth surfaces made of asphalt, concrete, or other pavement material. They are used for racing, and riders who can maintain an average speed of 18mph to 22mph even more, can enjoy using a 27-inch bike. Nonetheless, you must maintain your bike because a well-maintained bike will keep you safe and ensure smooth running.
History Of 27-Inch Bike
In the early 50s, the British started using 27-inch rims (630mm) on a few models of bikes. These 27-inch rims, in the late 50s, replaced the EA/1, which had a rim size of 597mm. The EA/1 bikes were best suited for rougher roads and terrain, but when better and smoother roads were constructed, they needed to be replaced by skinnier wheels and frames of the 27- inch rims. During this period, race bikes used 700c tubular (French sizing).
However, in the early 1980s, 700c bikes began to gain more popularity than 27-inch bikes. Riders preferred 700c clincher rims instead of the 700c tubular and 27-inch rim clincher bikes used in the 50s. This can be because 700c clincher rims are stronger, durable, and easy to install.
Size Chart Of 27-Inch Bike
Alongside the wheel size, you need to consider the frame size of your bike. A 27-inch bike can have frames of various sizes, that is, small, medium, large, X-large, and XX-large. X stands for extra.
The bike frame holds the entire bike up, including the rider’s weight. The bike’s frame size determines how much weight the bike can hold; the larger the bike frame, the more weight it will hold. In addition to this, larger bike frames provide room for taller riders to be comfortable as well as improve their handling skills.
The table below sheds more light on the size chart of 27-inch bikes.
|Frame Size||Rider’s Height [ Ft/In]|
|Small (51 – 53cm)||5’3” – 5’6”|
|Medium (54 – 55cm)||5’6” – 5’9”|
|Large (56 – 58cm)||5’9” – 6’0”|
|X – Large (58 – 60cm)||6’0” – 6’3”|
|XX – Large (61 – 63cm)||6’3” – 6’6”|
How To Determine Your Frame Size
You can know the frame size suited for your height by calculating your inseam length (in cm) and multiplying it by 0.70 (the factor used for road bikes). If it’s a mountain bike, a factor of 0.575 would be used for the calculation. However, the formula is:
Frame size = Inseam length (cm) X 0.70
Your inseam length is the distance between your crotch and your ankle bones. If you want to measure your inseam length, follow these steps:
- Make sure you remove your shoe so it won’t complicate the measurement.
- Create a distance of 6-8 inches between your feet.
- Measure the distance between the uppermost part of your thigh/ crotch/ pelvic girdle to the ground with a tape measure.
- Now, you can multiply your inseam length (cm) by 0.70 to find your ideal frame size.
After calculating your frame size, you can compare it with the table below:
|Frame Size (cm)||Frame Size Name|
|54 – 55cm||Medium|
|56 – 58cm||Large|
|58 – 60cm||X – Large|
|61 – 63cm||XX – Large|
Differences Between A 27-Inch And A 700c Bike
In the 80s, 27-inch bikes used to be the standard road bikes. But now, 700c bikes are currently the standard size for road bikes. 700c is named after the size of the bike tire. According to the ‘French system,’ 700 represents the approximate outside diameter of the bike tire in millimeters. The ‘c’ beside 700 does not represent centimeters but the bead seat diameter, and it is also regarded as the 622mm inner diameter.
A 27-inch bike shares differences with a 700c bike in the following features: Rim diameter, tire width, and wheel diameter. You can understand better from the table below
|Features||27 Inch Bike||700c Bike|
|Rim Diameter||27 inch||28 – 29 inch|
|Tire Width||25 – 27mm||20 25mm|
|Wheel Diameter||680 – 684mm||622mm|
From the table above, the results between 700c and 27-inch bikes proved that a 27-inch bike has:
- a larger rim diameter
- a smaller tire width, and
- a smaller wheel diameter.
Another difference between these bikes is that 27-inch bikes are vintage bikes while 700c are hybrid bikes. 27-inch bikes are vintage because they still retain the same look as when they were first manufactured, while hybrid talks about being compatible with other bikes like city and MTB bikes.
Differences Between A 27-Inch Bike And A 27.5-Inch Bike
You may wonder if there is any other difference apart from the additional 0.5 inches that a 27.5-inch bike has. A layperson, if given the same opportunity to state their differences, will think in the same line. Nonetheless, there are many other differences.
A significant difference between these bikes is that a 27-inch bike is a road bike while a 27.5-inch bike is a mountain bike known as ‘tweener.’
27.5-inch bikes have a bigger and broader tires, while 27-inch bikes have a larger wheel diameter. The table below will provide you with the exact values of the features for the different bikes.
|Features||27 Inch Bike||27.5 Inch Bike|
|Bikes||Road bikes||Mountain bikes|
|Rim Diameter||27 inches||27.5 inches|
|Tire Width||25 – 27mm||Up to 56mm|
|Wheel Diameter||680 – 684mm||584mm|
Other differences between these bike’s features are:
A 27.5-inch bike is more weighty than a 27-inch bike. The bigger rims of the 27.5-inch bike make the wheels heavy, impacting the bike’s overall weight.
The handlebars of 27.5-inch and 27-inch bikes are designed with flat and drop bars, respectively. The flat bars of the 27.5-inch bikes enable riders to be upright when riding, while the drop bars of 27-inch bikes place riders in an aerodynamic position.
Type Of Terrain
Mountain bikes like 27.5-inch bikes are designed for off-road riding. This bike can move on unpaved surfaces because its tires have knobs. However, 27-inch bikes are road bikes with smooth and skinny tires for riding on paved surfaces.
27.5-inch bikes have a mountain bike geometry so that the rider can attain an upright position, while 27-inch bikes have a geometry of a race bike for more aggressive and speed-oriented purposes.
Pros Of 27 Inch Bike
As mentioned above, the 27-inch bike might not be popular as 700C bikes and others. But, some features differentiate it from other road bikes, even mountain bikes. Compared to 26, 27.5, and 29-inch bikes, some riders prefer getting a 27-inch bike because of these reasons:
Better For Taller Riders
A 27-inch bike is suitable for tall riders compared to a 26-inch bike for short riders. At least riders between 5’3″ and above can still ride a 27-inch bike comfortably. The larger wheels fit the geometry of the bike better for talk riders.
Maintaining Average Speed
You can maintain your average speed faster with a 27-inch bike than a 26-inch bike. For example, maybe you average 1 mile per hour more quickly with 27-inch wheels than a 26-inch bike a few days after getting it. If you continue riding a 27-inch bike for a month-long tour, you could travel a couple of 100 miles per hour.
A 27-inch bike has better traction than a 26-inch bike. This is because it has larger wheels that allow more of the tire to contact the ground better, and at the same time, you can run it at lower pressure
Its Wheels Roll Better
Because a 27-inch bike has a larger diameter of wheels, it’s more comfortable when you hit a bump in the road. This can also save you from unnecessary fatigue after riding.
A 27-inch bike is lighter than 27.5 and 29-inch bikes. This makes it easier to carry if you can’t ride in a particular terrain. Also, its lightness makes it easier to maneuver than a 29-inch bike.
Cons Of 27 Inch Bike
These are the reasons why a 27-inch bike might not be suitable for some riders:
It Isn’t Ideal For Shorter Riders
If your height is less than 5’3″ or so, a 27-inch bike is not suitable for you. You’ll probably be okay with 26-inch wheels instead. The larger wheels have affected the bike’s frame size, so the stand-over height of the bike might be higher than your inseam length.
27-inch bikes are not popular as other road bikes. Because 700c can fit in some of its features, most people prefer getting a 700c instead of a 27-inch bike.
As a result of its unpopularity, 27-inch components are so scarce to get. Some people usually swap 700c inner tubes for 27 inches because their rim diameters are close. The parts are also expensive.
27-inch bikes are not popular alone; they’re also expensive. Compared to some other road bikes, some people can’t afford to get them. Instead, they prefer getting another road bike that can suit their budget.
The Wheels Are Heavier
Compared to a 26-inch bike, its wheels are heavier. Therefore, it might not be convenient for some people to handle.
Conclusively, after you have understood what a 27-inch bike is and the range of size suitable for it, you can find a 27-inch bike that suits your inseam length and start enjoying the comfort of riding
Though they’re rarely made nowadays, you can still find a few options in the market that are sized similarly to 700c road bikes.
