Bikes for Big Guys: Factors to Consider
A majority of bikes are manufactured with average-sized people in mind. For a long time, bike makers didn’t consider the turmoil that big guys were going through trying to ride regular bikes.
As more mountain bikes meant for hefty guys flood the market, here are some tips to help sift through the many models that exist.
Mountain bikes for big guys usually range from 250 lb all the way to 400 lb. The higher the number, the better for you.
However, you don’t want a bike that’s too heavy as that will affect the movement.
Therefore, go for a weight capacity that can accommodate your body weight comfortably without compromising on the other good qualities of the bike. A 300 lb bike sounds just about right.
Bike Frame Material
As a bike person, you can either go for steel, aluminum, or carbon frames.
Most mountain bikes never use carbon fiber frames due to the high costs involved. This leaves aluminum and steel as the only other options left.
Steel frames are stronger but heavy, a small price to pay when you consider how durable they can be. An aluminum alloy frame is better as they’re cheaper than carbon fiber, lighter than steel, and can support any body weight.
Having suspension forks in a hardtail bike is also an important thing.
Tires and Rims
In line with the weight factor, the tires and the rims need to be strong enough to support the weight of the bike and the heavy guys since they’re in contact with the ground. The tires need to be wide with good treads for good traction across all types of terrain.
The rims have to be strong, preferably an aluminum alloy, and with a good number of spokes to add strength to the wheels. If the tires and rims are of low quality, they will get spoilt very quickly, and this will affect the integrity of the whole bike, exposing the big guy rider to dangers.
If all you need is a leisure bike that can handle your weight, then go for something with a strong frame and tires that can work just fine in an urban setting. The Sixthreezero Around The Block would be the best fit for you in that regard.
If you’re looking for something heavier to help you exercise, then something big like the Mongoose Dolomite will be the right fit.
Figure out why you need a mountain bike, then find one that’s as close to your goals and purposes as possible.
Better mountain bikes cost a lot more and if you have the means to afford them, then go for it. However, you can still get a decent mountain bike for less than $1000.
If your budget is more constrained, then you can always consider going for a second hand, and multiple online sites offer them at very competitive prices. Always be on the lookout for such offers.
The Bottom Line
More bike companies are becoming aware of the needs of hefty guys, and as time progresses, the mountain bikes are getting better and coming out more refined. It would be best if you did not shy away from wanting a good bike for yourself that suits your need; it’s better than risking your well-being using a bike that isn’t built for your size.
There are countless stores, physical and online, where you can find the right mountain bike for hefty guys.
Use this guide and always ask around when you shop for more information. It may take some time, but at the end of it, you’ll get what you’re looking for.
