Why Get a Folding Mountain Bike?

Making an investment in a quality folding mountain bike might not come cheap. So, is it worth the price?

In the following section, we’ll list some of the most common reasons while a lot of bike riders shift to folding bikes every day.

Easier Storage

If you live in a smaller apartment or your garage if filled up with a lot of items, you might want to consider a folding bike. These bikes are significantly smaller in size when they’re folded and won’t need a huge space.

This makes them ideal for hikers, as you can easily store it anywhere in your tent without eating up all the leg space available inside.

Portability on Travels

Full-sized bikes are too bulky for bus and train rides, and you might require a special permit to carry one into them.

On the other hand, taking a folded bike along into public transport is usually free and unrestricted without needing any permissions or paying extra fees.

Lighter in Weight

Folding bikes are designed with portability in mind. The manufacturers expect that you’re more likely to carry them around, and therefore, they make them lighter in weight.

Not only will that make it easier to lift your bike, but it’ll also give you a little speed boost, as the bike won’t weigh you down as much.

Environment-Friendly Option

If you’re wary about the environmental impact of carbon-heavy journeys, getting a folding bike is a great way to become even greener!

Of course, using a regular bike is super environment-friendly. However, with a folding mountain bike in hand, you’ll get more opportunities to ditch the camper and go fully green on your hikes!

Saves You Money

Although a folding bike is usually more expensive than a full-sized counterpart, having a folding bike, in general, saves you money in the long run.

As you get to use them on more occasions than a regular bike, you’ll waste a lot less money on gas and car maintenance.

Things to Look for While Choosing the Best Folding Mountain Bike

While shopping for a good mountain folding bike, there are some critical aspects that you need to consider before making your final decision.

Here’s everything you should know regarding these factors, so you can pinpoint the ideal folder mountain bike for your needs.

Frame Materials and Durability

It’s crucial for mountain bikes to have a durable frame, so they can withstand all the shocks and unforgiven off-road terrain.

When shopping for a mountain bike, make sure it has either steel or aluminum frames, as these ones can support both your body and your gear weight while taking a lot of beating.

Avoid opting for carbon frames because they easily lose their tensile strength with time and can easily break.

Sizing Options

Bikes are available in various sizes to suit various body lengths. Make sure you check the ideal size option for the bike, so you can feel comfortable while using it.

Luckily, some bikes are available in wide sizing options that can fit teens and adults equally. These bikes are great options if more than one person will be using the bike.

The Folded Size & Ease of Folding

Since you’re mainly buying the bike to save space, it’s critical that you have an idea about its size when folded.

Additionally, check for a folding mechanism video of the bike that shows you how to do it correctly.

It’s ok to be a bit laggy in the beginning. But, once you get the hang of it, you’ll fold the bike in less than a minute.

Overall Weight and Maximum Limit

One aspect that’s always neglected until it’s too late is the weight specifications of the bike. With a folding mountain bike, you’ll be doing a lot of carrying.

That’s why it’s essential to make sure that you can carry the weight of your bike for quite some distance.

Moreover, mountain bikes mean that you’ll most likely have a gear backpack on you, so you have to count that in while figuring out the maximum weight capacity of the bike you’re going for.

Wrap Up

Back in the day, folding bikes used to be bulky and awkward. However, with modern technology and designs, these bikes became sleeker and with a much better convenience score than their predecessors.

A good folding mountain bike should be durable and easy to fold and unfold while supporting you and your luggage.

For that reason, we recommend the Montague Paratrooper Elite as the best overall folding mountain bike on the market.

However, if you’re looking for a more versatile option that you can use in more than just mountain rides, consider the versatile and popular option Xspec Folding Mountain Bike.
