Folding Mountain Bikes for The Money Buying Guide: How to Choose the Right MTB?

In this section, I will discuss the essential features you need to look into for your quality folding mountain bike. Read and understand each factor to have a solid grip on your decision.

Efficient Folding System

Considering you are planning to buy a folding bike, make sure to check on its folding system. Check for the pivots or hinge point of the bike model. Some foldable mountain bikes feature a quick-release mechanism and clip fastener in their folding order.

Nonetheless, you need to practice proper maintenance and lubrication to ensure it is easily folded.

Braking System

The most efficient and affordable brake mechanism for most bikes is the mechanical disc brakes. It provides more consistent and robust brake power compared to linear rim v-brakes. However, if you have enough budget in the future, you can always go for hydraulic disc brakes.

The Drivetrain

Regardless of the bike model and brand, securing your drivetrain is durable and efficient ensures your utmost performance. In that case, you have to look into the gears, cranks, and chainring of your foldable mountain bike.

So far, entry-level Shimano gear sets are the best choice for this matter. It comes at a reasonable and budget-friendly price without compromising quality. The chainring must be solid enough not to break that easily.

Meanwhile, the shifters and derailleurs must effectively guide the chainring as it transfers from one sprocket to another.

The material of the Bike Frame

The most popular material for your bike frame is stainless steel and aluminum. The former is heavier but sharp and resilient to natural elements. Meanwhile, the latter is lightweight and durable as well. Aluminum has better resilience against corrosion, yet at a higher price than steel.

Comfort

For this matter, you need to look into the saddle, suspension, and grip handle of your folding mountain bike. For the seat, the usual covering is synthetic or full-grain leather. There is enough padding on the saddle to ease the tension in your lower back and butt.

For the grip handle, it is mostly rubberized in texture with granular patterns to enhance gripping. Meanwhile, other bikes have their grip handle insulated with synthetic leather.

In contrast, larger wheels need more power in pedaling to go faster. Larger wheels are suitable for long rides, and farther distance traveled.

This one depends on your leg power and number of gear combinations. If you choose a fixed-gear foldable MTB, it has a lesser chance of conquering steep uphill terrains. Better choose those with 18 to 24-speed settings.
