Your bike should adapt to your body and riding style, not the other way around. That’s why we developed the Andros, an adjustable stem that not only adjusts for height, but also reach. So whether you want your bars high and far, or low and close, the Andros will adapt. A single quick release controls both the stem and handlebar so it takes only seconds to get the bars in the position you want. The Andros features a patented TwinStem design, making it extra stiff and strong.
You know the feeling: you’re on a ride and you need to adjust something and discover that you’ve left your bike tool at home. BioLogic figured that if the most handy tools could be stashed on the bike someplace, it would be one less thing to worry about. So they designed the T-Tool – a special bar end plug and hex key tool that fit right inside the handlebar grip – invisible but always there when you need it. The patented T-Tool features 4 mm, 5 mm, and 6 mm hex keys built into one handy unit with a long leverage design for the 5 mm and 6 mm tools.
The BioLogic FreeDrive encloses the bicycle chain to keep the rider’s clothing protected from grease and dirty spray. The FreeDrive’s ingenious design moves with the chain so it is friction free, unlike with some other chain protection methods. It also reduces chain vibration and noise. With a FreeDrive, you can say goodbye to bulky chainguards and enjoy the looks and cleanliness of a belt drive with the efficiency of a chain drive.
The Joule 3 is the lightest, smallest dynamo hub on the market and is one of only a handful that exceed the High Efficiency (HE) 70% threshold. Most other dynamo hubs have much lower efficiency; the lower the efficiency, the more drag you feel when you’re riding. The Joule 3 is so efficient, that you’ll hardly notice it’s there, even as you’re using it to power your lights or charge your phone. Best of all, with the Joule 3 you’ll always have power when you need it and you’ll never have to toss out a light battery again. The Joule 3 is CNC machined from 6061 aluminum alloy and meets rigorous German StVZO standards. Patented technology.
Running errands, shopping –- when you do these things by bike, you need to carry stuff. Portage racks are custom-designed for Tern bikes to help you carry your stuff, in lots of different ways. From the factory, Portage racks come with an elastic luggage strap that’ll keep even bulky items strapped safely to the top of the rack. Best of all, Portage racks are KLICKfix-compatible so all the bags out there with KLICKfix attachments, including the BioLogic Commute Bag, can be clicked on and off in seconds. Portage racks come in two versions — the Portage 20 rack, which fits 20” Tern bikes, and the the Portage 24 rack, which fits Tern 24” bikes and can take mid-sized pannier bags.
If you’ve ever used a traditional bicycle mini-pump, you’ve probably scraped some knuckles or ripped a valve and uttered a few choice phrases while you blew out your arms. That’s why we love the BioLogic PostPump, a full-size floor pump that’s hidden inside a seatpost. It pumps a much higher volume of air and the pumping action is easy, just like a floor pump, because you are using your whole body. And because it’s hidden in the seatpost, it’s always ready when you need it. The completely re-designed 2.0 version is slick and has an integrated Schrader and Presta adapter.
A bike without cables is an interesting design problem. How do we do it? Well in flat cities, you really only need one proper gear for going fast. So we did that and got rid of shift cables. We also use rear hubs with a back-pedal coaster brake which let us get rid of brake cables. Added bonus: bitchin’ skid marks. (Some countries require an additional front brake).
At night it’s important to see and be seen. A brighter front light illuminates road conditions in front of you and ensures others can see you. At 12 Lux, our new Deluxe LED Dynamo Front Light is 20% brighter and is engineered to cast a wider beam. That means light on the road where you need it, rather than in the treetops where you don’t. The new Handlepost Mount tucks the light out the way when riding and folding, keeping the light protected during storage. Ain’t progress grand?
Racks are great. They can carry tons of stuff while leaving you free and unencumbered to enjoy your ride. Sometimes, though, you might want to leave the rack off either for weight savings or for looks and that’s where a detachable rack comes in. Take it off when you don’t want it, or put it on when you need to haul some stuff. Three hex screws securely anchor the rack to the frame. The best thing is it looks like it’s just part of the bike and not an add-on.
Folding bikes have a sometimes deserved reputation for flexy frames. All Tern frames feature patented DoubleTruss technology which turns the rear half of the frame into a three dimensional truss so that it’s much more resistant to torsional forces. That equals increased stiffness and much better power transfer from the pedals to the rear wheel.
Ergon grips deliver the ultimate in ergonomics for the hand, reducing fatigue and numbness, even on the longest rides. Ergon’s grips are made from a newly developed BioKork material using 40% cork, sourced from certified, sustainable forests in Portugal. In addition, the inner core is plastic reinforced using natural fibre, which makes up 40% of its mass. In place of mineral oil, the gel in the palm section of the grip is vegetable-oil based.
If you’ve never ridden with bar ends, you owe it to yourself to give ’em a try. Stand up and climb or just haul ass, the extra torque and control is like nothing you’ve experienced before. GS2 grips are bigger with softer and more generous wings to reduce pressure on your ulnar nerve and ease wrist strain. The soft kraton rubber main body gives just enough while a textured rubber insert on top dissipates jolts and vibration. Originally designed for endurance mountain bike racing, the GS2 Leichtbau grips make long rides comfortable and provide plenty of options for positioning your hands as you ride. Welcome to 21st century grip technology!
The FBL 2 Joint incorporates the best features and technology from the award-winning OCL design: forged construction, interlocking interfaces, and patented Floating Point technology to avoid damage in transit. The FBL also incorporates two bearings in the construction so that the joint is always smooth and easy to operate. No planned obsolescence here – we’ve planned in serviceability: if ever the bearings need replacement, it’s an easy ten minute job by a dealer with industry standard-sized bearings that we’ll ALWAYS have in stock.
The FBL (Four-Bar Linkage) Joint is a tried and true design that keeps a frame securely locked. It features a forged and precision machined lever designed to offer a smooth surface for fingers. All other hardware is stainless steel for durability.
If you have a bike with small wheels, you have to work a little harder to get good gearing; you can’t just slap a 53/39 crankset and 12/25 cassette on a small-wheeled bike, the gearing will be too low. Our friends at FSA supply us with custom 55/42 cranksets and we pair them with wider 11/28 or 11/30 cassettes so you get a wider gear range and fewer overlapping gears.
When we find a way to make our frame and handlepost hinges better, sometimes we get a little crazy. That’s what happened when one of our friends suggested we have a look at Igus bearings. Igus says they are in business “to use its innovative polymer materials to develop products that provide creative solutions.” Man are they right. This ultra durable engineering plastic is amazing. No rusting. No grease required. Amazing durability. We now use super smooth Igus bearings in FBL 2.0, Physis and OCL joints. We make bikes to last long, designed for easy maintenance. Igus bearings fit that bill to an “t”.
Since a bike built for urban use needs to carry stuff, we decided to just make the rack a part of the frame. Integrating the rack gets us a rack is that much stronger and no heavier. The integrated rack is pannier compatible, perfect for trips to the grocery store. Our integrated rack also has a little secret –- it’s KLICKfix-compatible so all the great rack top bags from BioLogic, Ortlieb, Rixen and Kaul can be clicked on and off in seconds.
We wanted some really light, fast 20” wheels so we worked with Rolf Dietrich, one of the industries’ foremost experts on bicycle wheels, to develop this pair. Rolf was demanding: custom spokes from Sapim in Belgium, custom hubs from Bill Shook and American Classic, custom rims from one of the premier Taiwan factories where you can’t even go in the back room. Hand-laced and stressed with a custom spoke stress machine. Through three cycles. And spoke tensions measured only with a DT Swiss tensiometer. Seriously –- Rolf even specified the brand of tensiometer. But the result is a masterpiece, weighing in at only 995 grams for the pair and testing as by far our strongest wheels despite only 14 spokes in the front and 16 in the rear. Ultra-light, fast, and aero –- the ultimate 20” wheels. Patented technology.
A low-step design allows you to get on and off the bike easily, which is great for those who have difficulty getting on or off a bike, or for those who haven’t been on one in a while. It’s also great for people who like to ride in either tight jeans or skirts. The top tube is only 28 cm (11”) off the ground, making it one of the lowest on the market. The low center of gravity of the design also enhances stability, which less-experienced cyclists will appreciate.
When you need to carry more stuff on your bike, just plug the optional Luggage Truss into the Luggage Socket that’s welded to the head tube of every Tern bike. The Luggage Truss works with any bag, basket, or rack with a KLICKfix adapter. The benefit of a frame mounted luggage system (as opposed to fork or handlebar mounted) is that it doesn’t adversely affect steering. Available Tern accessories include: Kanga Rack, Tour Bag, and HoldAll Basket.
Our first-generation Magnetix were good and sticky. They did a fine job of holding a folded bike together. But in some situations – like carrying a bike up and down stairs – the magnets just weren’t strong enough. Our new Magnetix 2.0 increases the strength of the magnets by 300% to keep your bike folded even when being jostled and moved about. The previous Magnetix had a pull force of 4-5 Kgf. The improved version clocks in at 10-15 Kgf. We like the new Magnetix 2.0 a ton and think you will too.
If you could watch your chain, you’d see waves of energy literally bounce the chain as it moves up and down the cassette or when riding on rough roads. With the shorter chainstays of folding bikes, the waves just get amplified in size. The new Tern Mainstay Chain Guide is a patented design that dampens dangerous chain bounce without sacrificing shifting performance. Made from durable nylon, the Mainstay dramatically enhances chain stability to ensure your chain stays on the straight and narrow no matter how energetically you ride.
Proper chain tension on a hub gear in horizontal dropouts, when it’s also fitted with disc brakes, is an interesting engineering issue. We solved it with Marco dropouts, with integrated, adjustable chain tensioners and tunable disc caliper positioning. Custom CNC machined.
Folding bicycle design hasn’t changed much in decades. N-Fold Technology is a small but important change that results in a faster, and more compact fold. N-Fold Technology includes new frame and handlepost geometries and spins the front wheel by 180 degrees before the central fold, resulting in a package 40 mm (1.5") shorter. Using N-Fold technology, our Eclipse and Castro bikes are only very slightly larger than the typical small wheel folding bicycle. Bicycles with N-Fold technology can also be folded – easily – in less than ten seconds.
The Neos derailleur was developed to solve issues specific to small wheeled folding bicycles, specifically, ground clearance of the derailleur cage, and protrusion of the derailleur body from the chainstay, making it susceptible to damage. Working with Suntour, we developed the Neos family of derailleurs. The low-profile design mounts directly to the chain stay with the body of the derailleur tucked underneath, protected from damage. The ultra-short cage doubles the amount of ground clearance and produces lightning fast, precise shifts.
Every rider has a unique combination of body shape and riding position that feels most comfortable. That’s why a bike that adapts to the rider is so important. The Axis stem delivers an incredible range of height and reach adjustment. For storage, the Axis stem can be rotated 90 degrees for even more compact storage options. And the tool for making all of these adjustments? Stashed in your right handlebar grip.
The OCL Joint is a new reference in folding frame technology. It includes two new patents and everything we know about making the safest, strongest, and most durable frame joint.
- Taller, Stronger, Stiffer — Making the hinge taller and moving the pivoting surfaces outward from the center axis more than doubles overall strength and stiffness and it’s a difference you’ll feel from your very first ride. Every frame featuring the OCL Joint has been independently tested to exceed the EN safety standard by at least 50% (we stopped the machines after going past 50%).
- Norglide Bearings — The patented design puts sliding bearings between the moving parts so the folding action is always smooth and friction-free.
- Interlocking Halves — Unfolded, the joint surfaces lock together to improve torsional stiffness.
- Large, smooth lever — Large rounded surfaces are easy on your hands and give good leverage for easy operation.
- AutoLok Technology — Close the lever and it automatically locks in place, for extra, easy security.
- Floating Point Technology — Patented technology allows the lever to fold flat and brace against the joint for protection in transit.
- Serviceable — Good things are made to last and that’s why the OCL Joint is designed to be fully dealer serviceable. We keep every part in stock and replacing the bearings can be done in five minutes.
- Precision-machined — A machining tolerance of only 50 microns ensures a tight fit and eliminates looseness and rattling.
- Stainless Steel Bolts — Cold-worked stainless hardware delivers the durability and reliability needed for daily riding.
The Physis has quickly built a reputation as the stiffest folding handlepost on the market, but the Physis 3D takes it up a notch with 3D forging technology. The Physis 3D is forged from a single piece of aluminum. Only a small handful of factories around the world can 3D forge such a complicated, large piece. Welds are eliminated and material distribution optimized for strength. The result is a handlepost that is 2 1/2 times as strong as the original benchmark on rigorous EN tests. Plus, it doesn’t look half bad either.
The Q-Lock is strong: it exceeds tough European EN standards for strength and durability. The Q-Lock is also safe and easy to use. Close the handlepost lever and the AutoLock engages, holding the lever in the locked position. Forged 6061 aluminum.
There’s an unfortunate misconception that wide, large volume tires are slow and inefficient. We were guilty of this ourselves the first time our Swiss and German product guys recommended we try the Big Apple’s. But then we rode the tires and fell in love. As you might expect, the Big Apple’s are super plush and give a great feeling of security on streets where potholes, train tracks, and drainage gates are the norm. But they are also surprisingly fast and easy rolling. Integrated puncture protection and reflective sidewalls add to urban functionality. If you are interested, hit the Schwalbe Web site for technical information about why wide tires made with top quality materials can actually have a lower rolling resistance than skinny tires. Or ride them yourself and feel the difference.
The Citizen is everything you want in a great tire, and more. A solid all-around 20 inch city and touring tire offering superior riding dynamics and road feedback. Constructed of Schwalbe Basic Compound (SBC) with a dense 50 epi carcass, 65 psi max pressure and K-Guard puncture protection. The enhanced Kevlar protective layer is strong and safe and elastic. That means smoother running and a higher level of protection. In other words, a real nice tire.
Schwalbe calls their Durano tires mile eaters. We think they’re right. There’s plenty to love about these tires. Dual compound construction puts harder rubber in the middle for faster rolling and grippier rubber on the sides for cornering – something normally only found on race tires. A dense 67 epi carcass and 115 psi max pressure mean low rolling resistance, while a light tread pattern makes for better handling in the wet. Plus, you get RaceGuard protection against penetration punctures. Yum, Yum. Time to eat up some road.
We’re pretty sure the folks at Schwalbe were thinking ‘70s American TV when they named this tire because, yes, Kojaks are bald and more than a little sassy. Comfortable and surprisingly fast, we like the SpeedGrip multilevel dual compound for high levels of grip and low levels of rolling resistance. And there’s the proven RaceGuard protection belt, developed specially with racing in mind. Who loves ya baby? Kojak does. Ol’ Telly would be proud.
More people pick Schwalbe Marathons than any other bike tire in Europe — and the Marathon Supreme is the top of the heap in the Marathon line. Schwalbe’s great name in the touring field is well earned thanks to their durable line of tires with excellent handling. The Marathon Supreme addresses the needs of demanding everyday cyclists and touring riders and represents the most up-to-date developments in tire technology, puncture protection, good grip, light weight and low rolling resistance. In short, if you like what you’re hearing, you’re not alone.
The scuff guard protects the chainguard from bumps and knocks while keeping your feet and clothing clear of the chainring. It’s also a convenient handle for picking up and carrying the bike when folded.
The Alfine 11 hub is a masterpiece of engineering. 11 evenly and widely spaced gears are enclosed in the rear hub shell and deliver 409% of total gear range. But the hub is much more than this: it’s also very light, coming in even lighter than the already svelte Alfine 8-speed hub, and special needle bearings are very low in rolling resistance. Shifts (with an XTR style trigger shifter) are butter smooth and can be initiated any time, while you are stomping on the pedals or while you are waiting for the light to turn green.
In countries where bicycles are a primary mode of transportation –- the Netherlands, Germany, Denmark –- hub gears have always been the default choice of drivetrain. Hub gears have a number of benefits: with the gears all protected inside the rear hub shell, hub gears require almost no maintenance; they are much easier to keep properly adjusted; and you can shift from a standstill –- perfect after you’ve stopped for a red light. The Shimano Nexus 7 is one of the best hubs on the market –- 7 speeds are perfect for just about any kind of city riding and the shifting is super smooth.
The normal TIG welding process for aluminum bicycle frames is done by hand and involves the welder laying down a series of small, overlapping beads covering the two parts to be joined. The better the welder, the more uniform the beads. In the smooth TIG process, the welder makes a “double pass”, laying down a second layer of beads on top of the first. These beads are then sanded down by hand in an intensive process that requires extreme care. Done properly, the frame is strengthened because the possibility of stress risers is reduced. And the result is a very smooth weld joining the two tubes.
The quest for a wider gear range usually means slapping on extra chainrings. But we take a different approach: we pair an ultra-wide SRAM 11-36T cassette with a custom FSA 55T chainring for a gear range that’s wider than using a standard 53/39T double. But because we only use a single front ring, with no front derailleur, chain lines are better, shifts are faster, weight is lower, and there are no overlapping gears.
This is innovation. The Automatix is a 2-speed drivetrain that shifts automatically. No shifters, no cables. It detects your speed and shifts when you need it. First gear is for getting started and going up small hills, and second gear is for fast riding on the flats.
SRAM DualDrive mates an internal 3-speed hub with a 10-speed derailleur for 30 gears that deliver an awesome 578% range of gears. To you and us that means it delivers the low gears of a mountain bike and the high gears of a road bike –- all in one system. With only a single chain ring up front, the DualDrive system has a much better chainline and you never have to worry about cross chaining –- especially important for bikes with shorter chain stays.
The Syntace P6 is one of the strongest and precisely engineered seatposts on the market. We wanted the best so we worked with Syntace to develop a 580 mm seat post with a variation of their 3D cold-forged P6 clamp. Made from ultra-light 7075 aluminum and hard-anodized (black color option) for scratch resistance. ERS technology delivers loads of fore/aft adjustment for the saddle: you can run the saddle forward for zero offset stiffness, or all the way back like an offset seatpost. Two bolt micro adjust for infinite angle adjustment. Obsessive attention to detail means the bolts are positioned to for easy accessibility with 40 degrees of pivoting range.
The VRO 47 stem gives you all-important adjustability so you can fine-tune your riding position for speed or comfort. The stem is 47 mm long (14 mm longer than the standard VRO) and it’ll go anywhere from -45 degrees to +90 degrees or even backwards if you want to reduce the reach. And it exceeds Syntace’s brutal in-house test procedures for downhill gear. Custom-built for Tern.
Syntace is a German company renowned for their incredibly light but amazingly strong stems and bars. The Syntace VRO handlebar system used on select Tern bikes allows adjustment of handlebar height and reach for perfect rider fit. The system is stiff and strong but incredibly light.
- Extended cockpit reach and height adjustment
- Super light and strong
- CNC machined from 6066 aluminum alloy
- 120 g
- 78 mm x 40 mm x 17 mm
Getting this finish just right needed a LOT of work with our paint factory. It basically involves incredibly meticulous hand-masking to achieve the final result. With the silver/black finish, we hand-polish the aluminum frame to a mirror finish and then follow that with hand-masked black paint. Detail: the shape of a Tern’s tail is echoed in the paint masking.
No matter how light your bike, carrying it for any long distance is tiring; but rolling is easy. The Trolley Rack converts a bike into a rolling suitcase so even subway stations like Tokyo Main can be navigated easily. The included cover hides the bike and keeps you and other passengers grease free. Compatible with all Link models (exc. Link C7). Tern patented technology.
The oversized seat tube found on folding bikes makes designing front derailleur systems using standard parts a challenge. Some might even say a headache. So we figured it was time to make things better — and that meant a deep rethink about all the geometries involved in our front shifting systems. We think the result is a big step forward. Tern 20 and 24 inch bikes now feature optimized braze-on positioning, with a new custom boss for 24 inch models, coupled with new pulley position to reduce cable friction. Our aim is to deliver full-sized bike performance in portable bikes. Have a ride on one of our front shifting models and discover for yourself.
Engineered to integrate directly with the Andros stem or the Syntace VRO 47 stem used on many Tern bicycles, the Valo 2 is a powerful hub-dynamo powered light designed to help you navigate safely at night. It is optimally positioned for visibility and well protected from accidental knocks and bumps, as well as theft. Clarity™ optics projects the type of wide, even beam pattern that a cyclist needs - no more lighting the tops of trees in the distance or narrowly focused hotspots.
Designed with the lighting experts Herrmans in frigid Finland, where winter temperatures dip to -40° C and daylight all but disappears, the Valo 2 is made from cold-resistant ABS and has a standlight function so you're still visible to traffic while stopped. The patented CryoCore™ cooling design uses the handlebar as a heatsink to draw more heat away from the LED chip, allowing for brighter, more efficient ouput.
The Valo 2 is designed to work with the BioLogic Joule 3 or other standard dynamo hub, so you will never need to worry about dim lights or being stuck with dead batteries ever again.
