The Montague Paratrooper Highline is a full-size, high-performance mountain bike that offers all the features of a regular mountain bike with the added benefit of the folding design. This means you can take it with you nearly anywhere you go, and you don't need to buy a hitch or bike rack to take it to the trailhead. Mountain bikers will love it because of the large 27.5" tires and the RockShox X30 fork that lets you manually adjust the suspension. It also has a DirectConnect latch that ensures the bike won't fold up and collapse while you're riding. And, unlike a regular bike, you can store a folding bike in a closet or compartment so it's out of sight in your home or RV.

Quick and Easy Folding Design

Montague Paratrooper Highline Folding Bike Being Folded

The Paratrooper Highline takes approximately 20 seconds to fold up. You can do it in 3 easy steps. Open the quick-release latch on the front hub and pull the spring to remove the front wheel. Open the CLIX DirectConnect latch under the top tube and fold the bike in half. Use the included hook-and-loop strap to secure the front wheel to the folded bike.

The bike weighs just 29 lbs so it's convenient to carry wherever you go. It's easy to haul up and down stairs or place in your trunk or hatch for weekend excursions or after-work getaways.

  1. Shimano Deore 2-Speed Front Derailleur -
    Montague Paratrooper Highline HInges
    The Shimano Deore 2-speed front derailleur shifts the chain between high position and low position. It works with the Shimano SLX 10-speed rear derailleur to give the drivetrain a total of 20 speeds for you to choose from. The top swing derailleur creates a small profile so you can mount a water bottle to the seat post without obstruction. It's also dual pull, so the shifter cable can be routed to the shifter from either the top or the bottom of the derailleur. Routing from the top is great for mountain bikes because it helps prevent the shifter cable from getting hit by a rock or covered in mud.

  2. Shimano SLX 10-Speed Rear Derailleur -
    Montague Paratrooper Highline Rear Derailleur
    The Shimano SLX 10-speed rear derailleur shifts the bottom part of the chain between the 10 rear sprockets. It has a low-profile design with a short pulley cage that provides clearance above rocks, weeds, and other objects that you could potentially hit when riding hilly terrain. The lightning-quick action is perfect when you need to make sudden gear changes. It's constructed of lightweight aluminum that is designed for off-road riding. It works with the Shimano Deore 2-speed front derailleur to give the drivetrain a total of 20 speeds for you to choose from.

  3. 27.5" Kenda Kadre Tires -
    Montague Paratrooper Highline Tires
    The 27.5" Kenda Kadre tires are larger than standard 26" tires so they roll over obstacles better. They have a longer contact patch with the ground which gives you better traction, stability, and cornering ability on off-road terrain. The tires are constructed with a rubber compound that provides long tread wear and is extremely durable. The beaded tread is perfect for riding at high speeds and making quick turns and stops. The wheels have double-walled rims that provide increased support when compared with single-walled rims so they're better suited for off-road riding. The tubes have Schrader valves with cores that are easy to remove.

  4. Mountain Aero Saddle with Center Gap -
    Montague Paratrooper Highline Saddle
    The cushioned Mountain Aero saddle has a center gap that helps reduce pressure on your sensitive areas. This helps make it comfortable to ride on even for long periods of time. It's also easy to adjust to accommodate your height, and you can do it in seconds. Just loosen the quick-clamp, slide the seat post to your desired height, and close the quick-clamp.

  5. Kalloy Aluminum Frame with 5-Layer Brushed Coating -
    Montague Paratrooper Highline Frame
    The 20" frame is made out of 6061 aircraft-grade Kalloy aluminum tubing that is lightweight yet stronger than standard steel tubing. It's great for riding over rocks, through ditches, and navigating other off-road hazards. It also has a 5-layer brushed coating that helps prevent corrosion so it's great to use in wet conditions.

  6. Seat Post Hinge with CLIX DirectConnect Latch -
    Montague HInge
    The large hinge on the seat post connects the front and rear parts of the frame, keeping the point of articulation off of the top tube. This prevents the frame from developing a potential weak point as can happen with other folding bikes that are hinged on the top tube. It features a CLIX DirectConnect latch that automatically secures the hinge in place when the bike is unfolded. This prevents the bike from accidentally folding up and collapsing while you are riding.

  7. Shimano Deore 2x10 Rapid Fire Trigger Shifters -
    Montague Paratrooper Highline Trigger Shifters
    The Shimano Deore Rapid Fire trigger shifters are located on the right side and left side of the handlebars next to the hand brakes. They let you easily shift gears up and down using your thumbs and index fingers without having to move your hands off the grips. The shifter on the right shifts between 10 speeds on the rear derailleur. The shifter on the left shifts between 2 speeds on the front derailleur. An optical display on each shifter lets you easily see what gear you are in.

  8. Handlebar Brake Levers -
    Montague Paratrooper Highline Brake Levers
    The handlebar brake levers are located in front of each hand grip so you can steer and brake without having to move your hands. The right hand brake lever stops the front wheel and the left hand brake lever stops the rear wheel. The soft, ergonomic handles are easy to grip so your hands won't slide off them while steering.

  9. RockShox X30 Fork with Adjustable Suspension -
    Montague Paratrooper Highline RockShox X30
    The RockShox X30 air spring fork lets you manually adjust the suspension so you get the smoothest ride possible over rocky trails as well as smooth pathways. The blue LOCKOUT knob on the right side adjusts the stiffness of the compression. For pathways, turn the knob clockwise to increase compression damping so that the fork has little bounce. For rough terrain, turn the knob counterclockwise to reduce compression damping so that it bounces easier. The black PRELOAD knob on the left side lets you pump air into the springs so the psi level matches your weight. Simply remove the cap to add or remove air. The fork also has a quick-release latch that lets you remove the front wheel in seconds so you can fold the bike up fast.

  10. Tektro Auriga Hydraulic Disc Brakes-
    Montague Paratrooper Highline Disk Brakes
    The Tektro Auriga hydraulic disc brakes on the front and rear tires give you excellent stopping power. Hydraulic disc brakes require less force on the brake levers to stop your bike when compared with standard mechanical disc brakes or rim brakes. Since a tight squeeze on the hand levers isn't required you won't experience muscle fatigue in your hands and arms on long mountain rides. The disc brakes are closed and sealed to help prevent damage from water and dirt. They also require little maintenance so you don't have to manually adjust them as they wear down.

Video Transcript for Montague Paratrooper Highline Folding Bike Review

Hey, everyone. Colin here at etrailer.com. Today we're going to take a look at the Montague Paratrooper Highline Folding Mountain Bike.Now, this is a full-sized mountain bike that has the added benefit of folding up for easier storage and transport. Montague makes a full line of Paratrooper bikes. What sets the Highline apart from the other models is a couple of things. First we have bigger tires.

The other Paratrooper models just have 26" diameter tires. This one has 27-1/2" diameter tires. Now, even though the 1-1/2" doesn't seem like much, that's more surface area with the ground. It's going to provide a smoother ride, whether you're off-roading or even on pavement. The bigger tire is also going to make it easier to climb over obstacles when compared to those smaller 26" tires.The other thing is that we have hydraulic disc brakes on our Highline.

The other Paratrooper models either have mechanical disc brakes or V brakes, so that's going to be a lot more braking power with our hydraulic disc brakes. It's going to allow you to stop a lot more efficiently and quicker, especially in wet conditions.Now, at first, you might be a bit hesitant to ride a full-size bike that folds up. Honestly, I was too at first. One of the things I thought about was, "What if I'm riding it and then all of a sudden, it folds in on itself and I fall over" One of the things that kind of gave me more peace of mind when was I looked at their click system a lot closer.Now, their click system right here is very secure. It's not necessarily that easy to get the lever off.

See, you can't just use one finger right there. It comes up a little bit, but it's really hard to get it past that point with just that one finger. You got to use the whole hand, get my, all my fingers under it. You see I had that nice snap, letting you know there was a lot of tension holding it together.Now, if you find that your bike is pretty loose at this point, all you have to do to tighten it up is turn this silver knob on the back to the right to tighten it up, and that gives you more tension in it to make sure that it's really secure. And the other thing is, if for some odd reason your lever we're to unlock like that during your trip, the bike cannot fold up right now, because you actually have to push up on the latch right there to get it to unlock.

The click system really did take away any of the doubt I had in the folding bike.Now, another thing that really gave me confidence in this bike, and it's just kind of cool, is that Montague actually designed the Paratrooper with the help of the U.S. Military. They just wanted something that was going to be durable and compact. The name Paratrooper actually comes from airborne soldiers jumping out of planes with the bike strapped to their chest. When they would land, they could get the bike and set it up and be ready to go like that.Now, obviously, it's a folding bike. We'll go ahead and show you how to get it compact and ready for storage or travel. First thing we're going to do is remove the front tire. Now, we're also going to have the patented click system on our front and rear tires. When we want to remove them, we just pull that lever back. And from here, we do have to pull and push at the same time to get our forks off. You can just set the front tire aside.Now we'll come to the center and get that lever off. Then again, like I said earlier, you have to push up right there to get it to unlock. Flip it around. Want to make sure we have the handlebars folded in towards the tire. Then we want to grab this hook-and-loop strap, and we're going to pull it off. We're actually going to use it to wrap around the tire and then come back up to the handlebar. Once we get that secure, it's going to prevent our bike from folding out while it's in storage or in travel.Just grab the other tire. We'll lean it against the bike like so. And I'll just reach my hands through the spokes to the frame, pick it up, now I'm good to go.Another option you have to make it a bit more compact, you can take the pedal off so that lays flat on this side if you choose to lay it down. Or you could even just replace these standard pedals with folding pedals from Montague. That way, instead of taking it off, you just fold it up and it'll lay flat.Now, a couple advantages to having a folding bike is one being you don't have to invest in a hitch-mounted bike rack, or even a roof rack with a bike rack, to get your bike from point A to B. The other being if you live in a tight space, like an apartment or even a small house where you're limited on storage space, you're not going to have to chain it up outside or even just find space in your house to store a full size bike. You fold it up, it's in this compact size, it can go in the corner or even your storage facility.Now, take another closer look at our Highline. It's going to be constructed out of an aircraft grade aluminum, so that's going to be very durable and lightweight, so when you fold it up, it's going to be very easy to lift up off the ground and get it to where you need it. And we also have a five-layer anti-corrosion finish. It's also going to be matte gunmetal gray in color, which gives it a really nice look.Now, one of the things that makes Montague's folding bikes a bit superior to other folding bikes, is that the hidden point where the bike folds is integrated into the seat post tube. Some other companies might have their hinge in the middle of the frame right here, which could compromise the weight distribution when you're riding it. Now, if you think about it, when you're sitting on your bike, the weight's coming down on the seat post tube, so it only makes sense to have that hinge point right in line with it to make sure it can handle your weight. It's going to do a great job of dispersing your weight all throughout the triangle tubing down here.Now we're going to have really good grip on our handlebars just to make sure we don't lose our grip at all while we're riding, especially if it's wet outside. You can see I have full access in range to be able to access my brakes right here, and also my Deore Rapid Fire trigger system, which is going to help me with effective shifting when I need to go up or down.Now, up front, we're going to have a Deore derailleur from Shimano. It's going to help us with nice and easy transitions from first to second gear. Up front, we're only going to have two speeds, while on the back, we're going to have 10 speeds, totalling 20 for the bike. We're also going to have a Shimano SLX 10-Speed derailleur that's going to make for nice and easy transitioning when we got to shift up or down.Now, we're also going to be equipped with a Rockshox suspension system, which does a great job of absorbing any impact we have when going through some rocky trails. You can see right here, just pushing down, we have 100 millimeters of travel through our suspension system, and we also have the option to lock it out if we we're to ride on pavement. We just turn this blue knob at the top, and that locks it down so that doesn't travel through, taking away any of the energy you're using to pedal.It's also going to be equipped with an Aero Mountain adjustable height saddle. And it's also going to come with reflectors. We're going to have one on the front, one on the rear, one on each tire, the back and the front, and then we're also going to have two on each pedal.Now, I've worked with a lot of Montague's bikes, especially the Paratrooper line, and I like them all. They all do a really good job. I especially like this one because of the bigger tires. It's going to be a lot smoother ride, whether I'm off-roading or even on pavement. And it's also going to allow me to get over obstacles a lot easier, and the gear shift allows me to get into that lower gear for when I'm climbing a hill.When you're all done riding for the day, it's very easy just to stow in the trunk of your car for easy transport. Even with your smaller sedans like we have right here, it's very easy just to slide it in and be on your way.Thank you all for watching. That's going to do it for our look at the Montague Paratrooper Highline Folding Bike.
