Mountain biking is a fun way to get outdoors and stay fit and healthy. 

However, if you’re a bit larger in size, or if you want to attach a lot of cargo to your mountain bike, it’s important to make sure that your mountain bike can support the weight—you don’t want to damage the bike. 

Most mountain bikes, including Trek bikes, have a weight limit of 300 pounds. If you’re excited to find the bike that’s right for your needs, read on!

Trek mountain bike weight limit

As a rule of thumb, a Trek mountain bike can safely support up to 300 pounds. This is true of most other brands of mountain bike as well. While there are plenty of factors that can change the maximum weight that a bike can hold without breaking, such as the material the frame is made from, the number of spokes, and the speed that you ride the bike, bike technicians agree that 300 pounds is a good general weight limit for mountain bikes.

It’s also worth mentioning that the figure of 300 pounds is more of a guideline than a hard and fast rule.

Safety guidelines are meant to be as cautious as possible to minimize the chance of danger, so in practice, a bike might be able to support more than 300 pounds at some risk to the rider.

There are also too many factors in play to come up with one weight limit that suits every bike.

Trek 3700 mountain bike weight limit

The Trek 3700 has an aluminum frame, which means that it’s slightly more likely to have problems when carrying a lot of weight. 

Aluminum bike frames are designed to be both durable and conveniently lightweight, but when it comes to carrying heavy loads, they don’t provide as low of a center of weight for the rider.

This means that it might be harder for a heavy rider to maintain control of a Trek 3700 when going down hills at higher speeds.

However, the Trek 3700 does have the advantage of an open, comfortable design which is easy for people of all sizes to mount and dismount, and it’s cheaper than a steel frame bike like the Trek 820.

If you do plan on riding the Trek 3700 with a heavy load, it might be a good idea to invest in stronger wheels, since they’re typically the first part of a bike to show signs of stress.

Trek 820 mountain bike weight limit

The Trek 820 has a steel frame, so it’s a bit easier to control under heavy weight. Steel frames are considerably heavier than aluminum ones, so they provide a lower center of weight and more stability when the bike has a heavy load on it.

If you plan on loading up your mountain bike with lots of cargo for a trip, or you’re on the heavier side, the Trek 820 will provide plenty of stability and security for you.

How much weight can a mountain bike hold?

A Trek bike in particular, can hold up to 300 pounds. While there are many factors that can affect this figure, if you stick to this guideline, you’ll avoid any major damage to your bike.

A Trek bike can likely exceed this limit for short periods of time without showing signs of trouble, but it would be risky to yourself and the bike to consistently ride while exceeding the weight limit.

Can a 400-pound person ride a bike?

Yes, a 400 pound person can ride a bike! Unfortunately, Trek does not make bikes with strong enough frames or wheels to accommodate 400 pounds.

But this does not mean at all that a 400-pound person cannot ride a bike. Bikes like the Mongoose Dolomite, the Zize Bikes 29Er Max, and the Firestrong Bruiser Cruiser are all designed with 400-pound riders in mind.

What is the weight limit for a 26-inch mountain bike?

A 26-inch mountain bike can accommodate up to 250 pounds. This limit applies to all 26-inch bikes, not just mountain bikes.

As with bikes for adults or larger people, you’ll want to take into account what kind of stress you’ll be putting the bike through, what kind of frame the bike has, and whether you want to invest in sturdier wheels when deciding what kind of 26-inch mountain bike to buy.

Final Thoughts 

The short answer to “how much weight can my mountain bike hold?” is “300 pounds.” If you’re a heavier rider and you’re planning to do lots of intense riding, you may want to invest in a steel frame and some stronger wheels. 

If you’re a casual rider who just wants to do some low-intensity riding on a bike with a comfortable frame and feel, an aluminum bike like the 3700 may be right for you.
