Before Buying a Mountain bike for Big Men

While most persons can just jump on any type of bike, big guys must first consider a few important things. Let's get into them:


One of the first things you should always consider as a heavy rider is how much you weigh. Knowing your weight will go a long way in helping you choose the right bike and preserving the bike you choose. The recommendation is that you always go with a bike that is +/- 50 lbs of your body weight. 

By doing that, you would, in most instances, be fine. The truth is that most bikes support riders up to 350 lbs, but they typically only test up to 250 - 300 lbs. So while the bike you like heavy-duty mountain bike you want might not show that it supports your weight, as long as you weigh within the range, you'll be fine. You can also check out the custom made bikes from popular retailers like ZiZe. 


Getting a bike with enough tire width, treading, and size is also important for heavy men. Without the right size wheels, you are likely to either hurt yourself or damage the bikes. As such, you should get a bike with tires with enough room to bear your weight.


Without the right frame material to support your weight, you should expect to have issues. Frames come in many different types and qualities, so make sure you pay attention to getting a bike with a heavy-duty frame. The good news is that it's pretty easy to find a bike with a sturdy frame by simply looking at the bike's weight capacity as most of the weight is held up by the framework.


As an overweight guy, most of the products that support our weight are often more expensive than those for lighter individuals. But that doesn't mean you have to buy the super costly bikes. Most of the bikes on this list of best mountain bikes for big guys are very affordable. So you shouldn't have any concerns in that regard.
