Folding Mountain Bikes: A Cool Historical past, However Can They Shred?

I’ve lengthy been intrigued by folding bikes. They’re moveable, take up minimal area, and regardless of the small wheels, they’re surprisingly environment friendly, nimble, and enjoyable to trip round city. Made with bike commuters in thoughts, they’re additionally durably constructed and significantly cheaper than the working price of a automobile or frequent use of public transit. For city-dwelling commuters, the portability and stowability of a folding bike make it an exquisite choice for getting round city. However what about mountain biking? In case you’re touring lots or have restricted area in your house or automobile, the compact dimension of a folding mountain bike can definitely be intriguing. However are they succesful? Do they shred?

Folding bikes even have an interesting historical past, so if you happen to’ll permit me to nerd out for a little bit bit, allow us to journey again to the 1870s. Sure, folding bikes have been round lots longer than you may assume. One might even argue that folding bikes might have been the very first purpose-built, all-terrain bikes. 

Now, many inventors have tried to say that they have been the primary to invent the folding bicycle, and historical past is relatively unclear as to precisely who and when the primary folding bicycle was invented. What we do know is that in the course of the bicycle increase within the late nineteenth century, many inventors began tinkering with the idea of a conveyable bicycle. And there’s a shocking variety of early design sketches from across the 1870s and Eighties that included some sort of break-apart, folding, or in any other case disassemblable idea.

Within the US, the first patent for a folding bike was filed by American inventor, Emmit G. Latta, in 1887. Latta aimed to design a “machine” that was not solely “protected, robust, and serviceable, and extra simply steered than the machines now in use,” but additionally to be foldable “in order to require little storage-room and facilitate its transportation.”   

The First All-Terrain Bike?

The place it will get fascinating — from a mountain bike perspective — is that there are fairly a number of claims that it was in truth, the French military invented the primary folding bike, with a twin function of being an all-terrain bike. 

The navy folding bike idea was truly a partnership between French military lieutenant Henry Gérard and industrialist Charles Morel. Collectively they created a business mannequin that hit the French markets in April 1895. It was wildly profitable and the French navy quickly positioned an order for a take a look at fleet of 25 bikes for use for a bicycle regiment led by Gérard. 

The Romanian and Russian armies positioned orders as properly, and shortly bicycles have been adopted for navy use throughout the globe as many nations began their very own manufacturing of assorted folding bike interpretations.

Moveable bikes allowed troopers to cowl extra floor than being on foot alone, and shortly battalions of motorcycle infantry, scouts, messengers, and ambulance carriers have been commonplace. 

With the arrival of planes and paratroopers, the folding bike performed a fair larger position. Gentle and sufficiently small to be taken aboard airplanes, troopers have been in a position to be dropped from planes with parachutes and a folding bicycle in tow. As soon as landed, the bikes have been shortly assembled, and the troopers have been then in a position to shortly cowl vital floor.

English firm BSA (Birmingham Small Arms) produced these paratrooper-specific bikes by the 1000’s, and the BSA museum has saved great records of their various models and uses

Manufactured from metal, these bikes weighed round 32 kilos, had a single-speed drivetrain, and could possibly be outfitted with rifle clips and cargo luggage. Probably the most iconic use of the BSA airborne bicycle in motion was by the British and Canadian infantry on the invasion of Normandy, a.okay.a D-Day, on June sixth, 1944. 

Folding bikes stay in navy use to today, with the U.S. navy deploying troops in Iraq and Afghanistan aboard the Montague Paratrooper mountain bike.

Examined: Full-size, folding mountain bikes

Whereas business curiosity in folding bikes continues to be largely centered round highway biking and concrete commuting use, purpose-built folding mountain bikes are on the market. Some e-bike corporations like Rad Bikes and Aventon rolled out a fat-tired, e-folding bikes simply within the final yr. 

What I used to be intrigued by, nevertheless, have been non-assisted, full-sized mountain bikes which have the additional benefit of portability and compatibility for journey or for small-space dwelling. Not solely that, I wished to search out bikes that use normal elements, are suitable with aftermarket upgrades, and — after all— are off-road succesful.

I received two such bikes in for testing this winter: the military-style Montague Paratrooper Highline and the Change DF-812B. Each are vastly completely different in design but function full-size 27.5″ wheels, 20-speed drivetrains, disc brakes, and suspension forks. 

The Montague Paratrooper Highline $1,296

Montague is a well-established American folding bike firm with distributors in 20 nations worldwide. Additionally it is the corporate that provides the U.S. Army with its folding bikes for paratroopers and on-the-ground troopers alike. As such, the bikes are extremely sturdy and made to face up to all situations. Additionally they have a relatively distinct design. 

Whereas the bike options full-size 27.5” wheels, normal Shimano Deore componentry, and a familiar-looking Rock Shox fork, at first look, the body appears to be lacking a downtube. As a substitute, a single, outsized, flat tube has changed the entrance triangle.

At shut inspection, you’ll discover {that a} slim triangle is in truth current however the downtube is definitely discovered shut and parallel to the seat tube. That is additionally the place the folding mechanism is positioned. The good thing about this design is the usage of a “concentric seat tube design”. 

“In distinction to a conventional hinge that breaks the tubing and creates some extent that may flex, our design permits the 2 halves of the body to rotate across the seat tube after which overlap when within the driving place. The locking mechanism is definitely in entrance of the axis of folding which limits any flex,” defined Ryan Walas, Advertising and marketing Supervisor at Montague Bikes. 

The bike folds all the way down to a 36” x 28” x 12” package deal and is aimed toward city dwellers who’ve restricted area, and people touring to the paths with no automobile rack. One other section of consumers embody RV homeowners, #vanlifers, boat homeowners, and personal pilots who want a motorcycle that can match their restricted area whereas being able to tackling the numerous terrain they encounter of their travels

In its advertising and marketing materials, Montague states that in creating these bikes, they “got down to create the best efficiency folding bikes on the planet.” So how did this one fare?

I’ll admit that the very first thing I seen was the sheer weight of the bike. It might be a small package deal when folded, but it surely’s not a light-weight one. And whereas 34 kilos is under no circumstances outrageous for a mountain bike, it’s on the heavier finish for a hardtail, and it’s one thing I felt whereas climbing. 

Just like the Change bike reviewed under, the very first thing I did upon assembling the Highline was swap the quick 560mm handlebars for some extra affordable 720mm bars. Bars enormously affect the dealing with of a mountain bike, and wider bars enhance management and stability. Any bike we evaluate right here at Singletracks will probably include bars upwards of 720mm in size, and so I wished to present these folding bikes a good shot. 

The Highline is available in solely two body sizes —an 18” and 20” inch— and at 5’5”, the attain with the 90mm stem was a tad outstretched for me, so I swapped the stem for one thing shorter. Even with my tweaks, nevertheless, I might have possibly most popular a smaller dimension.

As soon as I received over how the bike seems to be, I used to be stunned to search out the burden to be pretty evenly distributed, even if the additional tubing, folding mechanism, and drivetrain are within the rear half of the bike. Extra importantly, I by no means frightened in regards to the folding mechanism coming undone mid-ride or some other issues of safety.

With a MSRP of $1,296, you will need to keep in mind that this can be a price range bike with entry-level elements. For that, they do their jobs simply high-quality even when one bottoms out sometimes. The Tekto hydraulic brakes and Deore shifting even withstood some excessively muddy winter driving. 

The general trip really feel is certainly extra on the lengthy haul cruiser finish of the spectrum relatively than a XC racer. Whereas the sturdiness and stability are instantly obvious, it lacks in snappiness or playfulness. I don’t doubt that this bike might carry luggage for an overnighter, function a heavy-duty commuter, or be disregarded within the Afghani desert for weeks on finish. Likewise, with a 24-36 low gear, it’s best to have the ability to slowly spin your approach up most hills, and with some further air within the fork, you’ll even have the ability to conquer some rougher terrain. But whereas it’s succesful and utilitarian, it lacks the responsiveness or nimbleness that make hardtail mountain bikes so enjoyable to trip.  

I’ll say that the Montague folding mechanism is probably the most user-friendly I’ve tried, and it takes however 20 seconds to take off the entrance wheel and fold the bike in half. 

The Change Bikes DF-812B, $1,880

Established in 2009, Change Bike is a Taiwanese firm that makes a speciality of full-sized folding bikes. They’re obtainable in North America through FlatBike.com, who informs me that some three dozen of those DF-812B fashions are already on the market on American trails. 

Their most important buyer base are apartment-renting MTB fans and RV homeowners with some boaters and personal pilots sprinkled in. 

Their patented designs are claimed to be lighter, stronger, and extra moveable than different folding bicycles in addition to 100% suitable with aftermarket equipment and simple to keep up. They’re additionally the one folding bike available on the market to have obtained the ISO-4210 security certification for MTB frames.  

Whereas Montague is their largest and most-established conventional competitor, Bob Forgrave at Flatbike.com revealed that “since a Changebike has an actual MTB body that rides like an MTB, the largest precise competitors comes from people deciding whether or not to mix a conventional aluminum hardtail (Trek, Specialised, Big) with carrying tools [aka external car racks] or just get a full-size MTB that rides inside [the car].”

This Change full-sized mountain folding bicycle was designed to “provoke a brand new period within the folding bike market.” So let’s see the way it rides. 

The bike arrived in a field about half the dimensions of an everyday MTB and with 3 times the equipment. Two units of pop-off pedals, a carrying bag, a saddlebag, and even some Allen keys have been included. There have been additionally a number of directions. This was useful as a result of the folding and refolding of this bike took some follow and was much less intuitive than the Montague mechanism reviewed above. 

As soon as assembled, the Change 812 seemed very very similar to an everyday bike. With the full-size triangle, 27.5” Mavic wheels, internally-routed cables, Shimano Deore element package deal, hydraulic brakes, and a Fox Float34 fork — this bike seems to be like a contemporary hardtail relatively than a folding bike with some knobby tires. 

Just like the Montague, this bike got here with actually slim, 580mm handlebars. Whereas I perceive the packing comfort of slim bars, I a lot choose wider bars for dealing with so I swapped these out for 720mm bars. 

The pop-off pedals have been a primary for me, and a neat invention that, because the identify suggests, lets you shortly pop your pedals on and off the crank arms with out the necessity of a pedal wrench or Allen key. 

Driving this bike was a very nice shock. With the addition of the broader bars, the bike seems like an everyday aluminum hardtail. It’s not the liveliest of hardtails however regardless of its 31-pound weight, it climbs properly and is a secure descender. Even within the winter mud, the Kenda tires keep respectable grip and the bike is loads responsive when pushed onerous into corners.

Body Materials 7005 aluminum, double-butted development,
Fork FOX Efficiency 32 Float
Drivetrain Shimano Deore
Crankset Deore with 170mm crabk arms and 38/24 chainrings
Cassette Vary 11-42T
Wheels Mavic Crossride 27.5
Tires 2.1 Kenda Nevegal Sport
Handlebars Aluminum Barbore in 580mm size
Brakes Shimano shimano BL-M615
Folded Measurement 30 x 37 x 15 in.
Claimed Weight Roughly 30Lbs
Precise weight w/ pedals 31.6 Lbs

The fork alone is an enormous improve from the Montague construct and whereas entry-level, the Deore package deal does its job. 

It was straightforward to neglect I used to be on a folding bike till trying down and realizing that the downtube and the secondary locking system extends a good bit past the underside bracket. It’s not obvious within the trip really feel however there’s a threat of clipping it whereas traversing rocky terrain. 

The low gearing and quite a few eyelets within the body are a pleasant contact for these wanting so as to add further cages or carry gear for lengthy days within the saddle. 

My solely fear with the Change bike can be upkeep. With two separate locking mechanisms, there are added transferring items and also you’d must be diligent about cleansing the bike. You wouldn’t need sand or dust in there. 

For these prioritizing area, the Montague did fold down right into a smaller package deal however you get much more bike in Change.
