In theory, you’re supposed to be able to push the bike when it’s folded, keeping the seat raised so that you can steer with it, but I found doing this to be more cumbersome than it was worth. Like most of these bikes, the Mariner D8 was awkward to carry one-handed in my tests. Folding-bike expert Steven Huang’s pro tip is to keep the folding bike open and turn it around so that you can rest the seat atop your shoulder for easier carrying, especially up and down stairs.


This British WWII Airborne BSA folding bicycle was rigged so that, when parachuted, the handlebars and seat were the first parts to hit the ground (as bent wheels would disable the bike). BSA abandoned the traditional diamond bicycle design as too weak for the shock and instead made an elliptical frame of twin parallel tubes, one forming the top tube and seat stays, and the other the chainstay and down tube.[5] The hinges were in front of the bottom bracket and in the corresponding position in front of the saddle, fastened by wing nuts. The peg pedals could be pushed in to avoid snagging and further reduce the space occupied during transit.
The market for folding electric bicycles is growing quickly as people realize the advantages of this unique method of hybrid transportation – and the world of folding bikes is no different. So to help you figure out which product is right for you, we’ve put together a list – the 5 best folding electric bike reviews for 2018! Read on, and see what product works best for your unique situation.
The two most common types of hub motors used in electric bicycles are brushed and brushless. Many configurations are available, varying in cost and complexity; direct-drive and geared motor units are both used. An electric power-assist system may be added to almost any pedal cycle using chain drive, belt drive, hub motors or friction drive. BLDC hub motors are a common modern design. The motor is built into the wheel hub itself, and the stator fixed solidly to the axle, and the magnets attached to and rotating with the wheel. The bicycle wheel hub is the motor. The power levels of motors used are influenced by available legal categories and are often, but not always limited to under 750 watts.
The environmental effects involved in recharging the batteries can of course be reduced. The small size of the battery pack on an e-bike, relative to the larger pack used in an electric car, makes them very good candidates for charging via solar power or other renewable energy resources. Sanyo capitalized on this benefit when it set up "solar parking lots", in which e-bike riders can charge their vehicles while parked under photovoltaic panels.[66]
Our claims of smaller, lighter, safer or easier to use are based on our research of other folding bikes on the market (specifically, folding bikes that have wheels of at least 16"), we haven't found anything smaller, lighter, safer or easier to use. (Folded size is based on volume, L x W x H). That doesn't mean that as we move forward with production, those claims will remain unchallenged. What is true of the market one day, may not be true the next.
Your most viable option may be a folding bike. Only now you have to figure out which model to choose. Assuming that you shop online, you can use each folding bike's description - and accompanying images - to determine not only how compact that bike will be, but also how much it weighs, how long it takes to pair down, and what, if any, tools might be required to make any adjustments or repairs.
From the leading manufacturer of folding bikes, the eight-speed Dahon Mariner D8 offers all of the features and performance most commuter cyclists might want in a folding model in a practical, affordable package. First, it’s comfortable to ride, going smoothly over bumps and shifting fluidly up and down hills. Second, it folds and unfolds quickly, and latches securely into both modes. Its design also addresses practical concerns: It has fenders to avoid rainy road splashes on clothing, plus a rack to carry stuff. Finally, it’s a good value—as with full-size bikes, in folding models you generally get what you pay for. But in the Mariner D8 you get a good-quality folding bike with the features you need for less than $600.
One of the biggest advantages of a folding electric bicycle is that they are operable completely manually – if you run out of power, you can just ride your bike as you would normally until you get a chance to charge up. This makes them extraordinarily versatile and allows you to take extended trips on your bike with no fear of being stranded when out of power.

Finally, Brompton bikes are customizable, which means you can choose the frame material (steel or a superlight combination of steel and titanium); the handlebar shape (four options); the number of gears (one, two, three, or six) and the gear ratios (three choices); the suspension type; the tire type; the saddle type and height; accessories such as the fenders, rack, front bags, and lights; and the paint color. A single-speed Brompton starts at about $1,200; the one we tested, the S6L, came outfitted with sport-style straight handlebars, six speeds ($220 more), fenders ($80 more), a front carrier block for attaching a bag and a front flap bag ($185 for both, bag not shown), and rechargeable battery-powered lights ($110, not shown), totaling about $1,795.
German designers Heiko Müller and Markus Riese began working on the Birdy in 1992 for their university thesis – the first model comprised of parts of two old bicycles welded together. Fast forward 26 years and the Weiterstadt-based company have mastered the art of folding bikes. With 18-inch wheels for a more stable ride than the Brompton, the Birdy City offers impressive stability and comfort, and its aggressive, sporty geometry means it’s faster than many of its competitors. At 12.8kg, it’s not the lightest model around, but if you’re happy to take that hit in favour of a superior ride it won’t let you down. Eight-speed hub gear, front suspension/rear shocks, disc brakes adjustable-height handlebars and optional rear rollers all tick the right boxes, and although it’s not the smallest fold, it only takes 20 seconds or so to pack it down for the train or trunk.
Torque sensors and power controls were developed in the late 1990s. For example, Takada Yutky of Japan filed a patent in 1997 for such a device. In 1992 Vector Services Limited offered and sold an e-bike dubbed Zike.[9] The bicycle included NiCd batteries that were built into a frame member and included an 850 g permanent-magnet motor. Despite the Zike, in 1992 hardly any commercial e-bikes were available.
The Tern Link B7 rides great, folds and unfolds quickly (in the same manner as our top pick, the Dahon Mariner D8), and has a forged aluminum crank and a decent-quality seven-speed Shimano rear derailleur and shifters, all for a price that’s on a par with that of cheaper bikes built with no-name components. What’s missing are a rear rack and fenders (available for purchase separately from Tern). This model also has a slightly larger all-around footprint than the Mariner D8.
In the event that you're going to be living somewhere for an abbreviated period of time, a folding bike might be a smarter choice than a car, as long as your daily commute isn't too far. For many city dwellers, there is simply no place to park a car where they don't have to worry about getting a parking ticket on random days. A folding bike is ideal if you're living in a dorm room or a temporary apartment. Another benefits besides the low upfront cost, is the tremendous resale value many have, which means that you can recoup a lot of the bike's original cost when it's time to sell.
The Dew-E packs functionality and fun into a rather traditional and conservative package. Front and rear fenders, integrated Busch & Müller front and rear lights, and a built-in Abus wheel lock make this a very practical commuter bike. An 11-34t 9-speed cassette and 1.75-inch tires provide versatility: You’ll stay smooth over rough city streets and zip down gravel bike paths with confidence. Front and rear rack mounts also give you the chance to outfit this bike for carrying more cargo or supplies for a longer day on the bike. Whichever way you think you’ll be riding an e-bike, this bike deserves a second look.
If you have very little storage space and love to bring your bike on vacations, you should look at the Goplus Electric Folding Bike. It has a powerful battery that’s removable and allows you to go up to 30 km per charge. To fully charge the battery, you’d need about 5 to 6 hours. It charges easily, and its charger is UL approved for safety. The bike is made of aluminum alloy with the front fork made of high-strength carbon steel. It features a quick release clamp that allows you to fold the bike quickly and easily. The bike weighs 55lbs, and when folded, it measures 33’’x26’’x14’’ (LxHxW). Both front and rear brakes are reliable and guarantee safety. The seat height is adjustable, so you can go up or down a size if you’re maybe sharing the bike with someone else. The bike comes partially assembled, and if you’re not a professional, I suggest you have someone help you with tightening everything into place.

The eight-speed Tern Link D8, the company’s most popular model, provides a few upgrades over the Mariner D8 that may suit taller riders or those willing to pay more for some higher-end components. Our test riders raved about the proprietary handlebar stem, which allows both height and angle adjustment via two easy quick-release levers. One bike expert praised the design of the rear derailleur and front brake, both of which sit close to the frame to reduce snagging, as well as the “top-shelf” puncture-resistant tires. Still, our testers’ reviews were mixed regarding the fold, which positions the handlebars outside the folded package—some testers found this setup easy to manage, others preferred the tighter package (and lighter weight) of the Dahon model.
Commuting Made Easy – Commuting is made easier as the foldable electric bikes do not require much space for parking and can be easily folded and carried through train or bus stations anywhere. The major benefit of a power bike is that there are no more traffic problems. You can easily cruise through due to its speed and when you see a traffic jam just fold it and start walking through the jammed passage. Moreover, the speed of this bike can get you to your destination in less time. No more being late.

The number of gears specced on your new machine will be important too. If you expect to keep your journeys to flat city streets, a singlespeed (just one gear) will cut down on maintenance and overall weight. However, those who expect to ride hilly terrain will be pleased to hear that there are plenty of folding bikes that come supplied with triple chainsets and 11-32 wide ratio cassettes. This will offer an easier ride on the inclines, but will add to the weight.


"I never lock my Brompton. I just fold it and carry it with me. I have several bikes, and at 24 lbs my Brompton is the lightest bike I've got! I take it in its sack on the Long Island Railroad and everybody assumes its just a large soft-sided attache case. The bike is quite nimble but is not the fastest two wheeler on the street. I wouldn't want to ride it to Chicago but its great for errands around town and the trip between Penn Station and Wall Street or for a leisurely trip from my home on Long Island to anywhere within 25 miles or so."
Our test bike was a six-speed, Brompton’s most popular option, configured with a three-speed internally geared front hub (gears 1, 2, 3) and a rear derailleur that shifts between two external gears on the rear hub (called + and –). Though the internal gearing is certainly a higher-end feature, the shifting itself takes some getting used to—you aren’t supposed to pedal when changing the front gears, but you do need to pedal when changing the rear, so you have to remember which gear you’re in (or glance down really fast). And to go from, say, 2– to 1+ to climb a hill, you have to coast and drop way down to 1– using your front shifter and then pedal while shifting back up to 1+ using your rear derailleur (the alternative is to pedal really hard for a moment to go from 2– to 2+ in the rear, and then coast while shifting down to 1+). I also perceived a big difference between the gears, so I sometimes felt like Goldilocks, forever looking for the gear that was “just right.” This problem may have been remedied, though, with a custom gear ratio, which I didn’t get to select on the test bike.
Mate Bikes is focusing on volume right now, which helps to explain why its prices are so low. The company first wants to establish itself as a global brand, before introducing more premium bikes in 2019 and 2020 (a cargo bike is coming) using materials like carbon fiber. For now it earns money on thin margins and by up-selling buyers on higher-margin accessories. And yes, Mate Bikes, like most bike manufacturers, uses off-the-shelf components like Shimano shifters, LG batteries, and Bafang motors, but it’s not a white-label Chinese bike, the company assures me. The Mate X frame, for example, has been customized to the point of now being considered an original design, and each component has been independently selected to achieve the targeted cost and performance required from the overall product.
Not all e-bikes take the form of conventional push-bikes with an incorporated motor, such as the Cytronex bicycles which use a small battery disguised as a water bottle.[44][45] Some are designed to take the appearance of low capacity motorcycles, but smaller in size and consisting of an electric motor rather than a petrol engine. For example, the Sakura e-bike incorporates a 200 W motor found on standard e-bikes, but also includes plastic cladding, front and rear lights, and a speedometer. It is styled as a modern moped, and is often mistaken for one.[citation needed]

The folding bike may be the most convenient mode of transportation on two wheels: It can get you from point A to point B just as readily as a full-size bike, but you can stash it in a car trunk, tuck it under a desk, or store it in a closet. To suss out which folding bike does it all best for most commuter riders, we pedaled and shifted, folded and unfolded, and carried and maneuvered 11 popular models from eight manufacturers. After our 60-plus hours of research and testing, the well-designed Dahon Mariner D8 edged to the front of the pack, combining a comfortable ride and easy folding with good-quality components, all for a reasonable price.
This is list of the best performing, best value electric bikes for 2017 / 2018.

A hinge in the frame may allow the rear triangle and wheel to be folded down and flipped forward, under the main frame tube, as in the Bike Friday, Brompton Mezzo Folder, and Swift Folder. Such a flip hinge may be combined with a folding front fork, as in the Birdy. Swing and flip hinges may be combined on the same frame, as in the Brompton Mezzo Folder and Dahon, which use a folding steering column. Folding mechanisms typically involve latches and quick releases, which affect the speed of the fold/unfold. Bike Friday offers a model, the Tikit, featuring a cable-activated folding mechanism requiring no quick releases or latches, for increased folding speed.

A foldable e-bike is heavy due to its installed engine. Many bikes give the property of portability. These bikes have different features and most people search for foldability. If the bike runs out of charge and the pedals do not let you move the bike anymore then this foldable feature may come in great use. Even though it cannot be carried by hand it can be stored in a car. On the other hand, if you want to take your e-bike on the beach or any other track to exercise, then the portability factor will make you love your bike.

Cheap folding bikes: The saying ‘you get what you pay for’ mostly rings true here. You can pick up a folding bike for under £200, and you can also spend well in excess of £2000. A cheap folding bike will do the job for you – but you can expect it to be heavier than more premium offerings thanks to lower end components and a more hefty frame. Finding the right option for you comes down to choosing which side of compromise to sit on.
Folding bikes have long been popular among commuters who need to store their bicycle in a small space at home or in the office. Thanks to their small folded size, they are easy to get onto trains and buses, or even a taxi. With the rise in popularity of electric bikes in recent years, it is no surprise that folding electric bikes have come onto the market as well.
You see, I’m not really a cyclist. It’s not that I’m lazy or out of shape. I run between 3 to 5 miles a day and could pedal if I wanted to. It’s just that I generally think of electric bicycles more like little electric motorcycles that don’t require me to get a motorcycle license or pay for insurance or registration. They’re for getting around quickly and effortlessly.

If you expect to be cycling in your office clothes, and want to ensure that you don’t bear a maker of your mode of transport on your attire, then chainguards and mudguards would be a useful addition. Provision for luggage, a frame mounted pump and integrated lights are all ‘nice to have’ accessories which you can feel justified in expecting on higher end models.

E-bikes use rechargeable batteries, electric motors and some form of control. Battery systems in use include sealed lead-acid (SLA), nickel-cadmium (NiCad), nickel-metal hydride (NiMH) or lithium-ion polymer (Li-ion). Batteries vary according to the voltage, total charge capacity (amp hours), weight, the number of charging cycles before performance degrades, and ability to handle over-voltage charging conditions. The energy costs of operating e-bikes are small, but there can be considerable battery replacement costs. The lifespan of a battery pack varies depending on the type of usage. Shallow discharge/recharge cycles will help extend the overall battery life.
