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.
Once I’d done my part, I invited eight cyclist friends over for test rides, asking them to rate the ride quality and the ease of folding and unfolding, as well as to provide commentary and suggest a price, as a way to gauge their perception of value. (Note: The Mariner model they tested was the D7, but we’re confident they would have similar opinions on the upgraded D8). Finally, I asked bike expert Damon Strub to peruse the spec sheets and highlight any pros or cons of each model.
This electric bike is an amazing e-bike which can carry the weight of up to 300lbs which is supported by fat tires that makes your ride less bumpy. It goes for 23 mph and can cover up to 55 miles. It comes with different features like a port for the USB cable to charge your phone. It has 7-speed gears that make you travel at different speeds according to your requirement.
Because e-bikes are capable of greater speeds for longer periods of time than standard bikes, you want extra control. Wider tires provide traction and some bump absorption with little penalty. You also want strong brakes to slow you (and all that extra weight) easily. It's worth looking at the quality of the brakes and investing in bikes with better ones if you can.

Controllers for brushless motors: E-bikes require high initial torque and therefore models that use brushless motors typically have Hall sensor commutation for speed and angle measurement. An electronic controller provides assistance as a function of the sensor inputs, the vehicle speed and the required force. The controllers generally allow input by means of potentiometer or Hall Effect twist grip (or thumb-operated lever throttle), closed-loop speed control for precise speed regulation, protection logic for over-voltage, over-current and thermal protection. Bikes with a pedal assist function typically have a disc on the crank shaft featuring a ring of magnets coupled with a Hall sensor giving rise to a series of pulses, the frequency of which is proportional to pedaling speed. The controller uses pulse width modulation to regulate the power to the motor. Sometimes support is provided for regenerative braking but infrequent braking and the low mass of bicycles limits recovered energy. An implementation is described in an application note for a 200 W, 24 V Brushless DC (BLDC) motor.[43]
It's my 1st electric bike so I don't know what really to expect but one thing I do know is that this thing moves. I use it to commute to work over the Williamsburg bridge. 15 min bike ride compared to 35min on a given day on the train and the assistance help me to stay cool and dry with minimal work. I am very impressed with the quality as well. One thing to note, this bike is heavy. Once folded you won't be carrying this no where. It's at least 50lbs. And where the carrying bar is located it makes it difficult.

And indeed, the company’s best seller, the Mariner, ranked as the first choice after our testing thanks to its features, as it ticks all the boxes on the list of what most commuter riders want in a folding bike. First and foremost, we found it smooth to ride and to shift—with the newest model, the D8, rigged with a Shimano trigger shifter, an upgrade to the twist shifters seen on the previous D7 and many other folders—and appropriately geared for pedaling up hills. (I rode up the Queensboro Bridge to Manhattan comfortably on the fourth-easiest of its eight gears.) It folds down quickly, in about a five-step process, and locks together with a magnet between the 20-inch wheels.


Common to almost all models is that the handling is more responsive than on a full-size bike, and that can take some getting used to. It is not advised that you ride a folding bike with no hands or try any cute stunts. Gears on small-wheeled folding bikes are higher to compensate, but limited gearing on some models may slow you down. If that is a major concern for you, you might want to look more toward higher end "performance" folding bikes. If you plan to take a lot of trips that utilize transit, a bike that folds quickly and compactly may be best for you. If you are a tall rider, you may want to check out how each type of folding bike can adjust to fit you.

E-bike usage worldwide has experienced rapid growth since 1998. In 2016 there were 210 million electric bikes worldwide used daily.[33] It is estimated that there were roughly 120 million e-bikes in China in early 2010, and sales are expanding rapidly in India, the United States of America, Germany, the Netherlands,[2] and Switzerland.[34] A total of 700,000 e-bikes were sold in Europe in 2010, up from 200,000 in 2007 and 500,000 units in 2009.[35]
After a very wait, Brompton finally announced its first electric bike in 2017. The Brompton electric has the same design and folded size as non-electric Brompton folders. The differences are the motor on the front wheel and a 300Wh battery bag clipped on the front luggage block. These additional parts make the bicycle heavier at 30.2 lbs for the 2-speed version.
Bike Friday - this high-end brand offers many types of folding bikes for those most concerned with performance. All Bike Fridays use 20" wheels and are built to fit into a suitcase for travel. Many also quick-fold and fit into a travel bag for use in commuting. A typical "stock" model (most Bike Fridays are custom made) quick-folds in 30 seconds to 27" X 27" X10" and weighs in at 24 pounds. Bike Fridays range in price from about $730 for a stock model to about $3400 for their best custom-made bikes.

Also, the power button was a pet peeve for me. You only need to hold it for a second or so to turn it on, but you have to hold it down for probably 5 full seconds to shut the bike off. If you don’t hold it down long enough, the bike doesn’t shut down all the way and just goes into “standby” mode. When I would hop off and park the bike, I found myself just standing there awkwardly while holding the button and waiting for it to turn off before I could lock it and walk away.

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]

We’ve updated the section on our upgrade pick, the Brompton S6L, to include information about Brompton’s recent voluntary recall. The company says that the recall is more of a safety precaution than a reaction to reported injuries or experiences of compromised quality. We’re still confident that the Brompton S6L is the best upgrade choice for a folding bike.


A big selling point of the attractive Citizen Bike Seoul, sold direct from the company’s website, is that it comes straight out of the box ready to ride—on our test unit, even the tires were inflated. Unfortunately, we didn’t find the ride and gearing as smooth as those of bikes costing just $100 more. Though the folding and unfolding were easy, the magnets simply wouldn’t hold when the bike was folded, and it kept flopping open (especially problematic when I was carrying it down subway stairs); the company told me that an update on that was coming. Plus, the Seoul’s folded footprint was so large it wouldn’t fit through the subway turnstiles.
After evaluating the seven-speed Tern Link B7, I had to double-check that it in fact retailed for just $400. For starters, it rode great, an opinion that all nine of our cyclist testers shared—one tester, suspecting it was one of the pricier bikes of the group, said that even if it cost $500, he would buy it that day. (I don’t think he actually did buy it, but he was pretty pumped when I told him it came in under his estimated sticker price.) Bike expert Strub confirmed that “it’s a lot of bike” for the money, praising its “clean frame design” and pointing out that it had the same Shimano derailleurs and shifters and similar 20-inch Kenda tires as the Mariner D7, which usually retails for nearly $200 more; the updated Mariner D8, however, improves on the derailleur and shifter for the same D7 sticker price. I found the fold, which is like the Mariner’s, to be a cinch, and the magnet snapped tight every time. The Link B7 also has ergonomic handlebar grips similar to the ones we like on the Link D8.
I found the $49 optional thumb throttle to be very useful. It’s a great way to get yourself easily out of a mess like deep sand or mud, while walking alongside the bike. It’s also useful when you want to make a quick start from a stop light without having to shift into a lower gear, or when you’re feeling lazy and want to cruise along without peddling.

It absorbs shocks well and the tire quality makes the ride smooth and easy. It has 8-speed gears that allow you to pedal accordingly. This e-bike is not just electric but can fit into different places like a motorbike. It does not take up much space and can be parked easily. Its speed lets you travel faster than a car. This may result in a great collection as you won’t be late and will also help you lose some calories.
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.

Folding bike adjustability: Most folding bikes will be ‘one size fits all’, with a great deal of adjustability – meaning that it’s easy to share the bike across members of your household. However, if you know this is an important consideration, it’s worth ensuring that the model you buy offers a wide range of adjustment that’s easy to use. Brompton bikes, for example, have a long seatpost that is adjusted via a simple quick release lever, making it easy to swap between riders.
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.
But that doesn’t mean the Oyama can’t fold as well as the rest of them. In addition to the standard two points of folding, one at the middle of the frame and one at the handlebars, the Oyama also has a third folding point at the top of the handlebars. That one allows the handlebars to rotate forward and make the bike just a bit smaller in folded form, and also helps to protect the brake levers, display and other goodies mounted on the handlebars.
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.

“I am a big mountain biker and over the past couple years have taken a couple of electric folding bikes with me on various trips around the Southwest. I ride hard on the mountain bikes, then use the eFolders to get out and see the nooks and crannies of the town we are staying in … Mammoth Mountain, Big Bear Resort, Sedona, Springdale near Zion National Park, etc. I leave my truck in the parking lot and explore on the eFolder … after a hard day of riding the electric aspect is great … don’t have to worry about hills! Also the folding nature allows the bikes to transport easily, and store easily in the hotel or condo.”
There are two types of people in this world: those who like fat-tire bikes and those who don’t. I’m very much of the fat tire persuasion, which is why I just had to test the new Mate X electric folding bike. There’s something about those big knobby wheels that speaks to my desire to forge a new path, to take the road less traveled. To explore strange new worlds and go where no one has gone before, even if that’s just to the corner store.
Also, the power button was a pet peeve for me. You only need to hold it for a second or so to turn it on, but you have to hold it down for probably 5 full seconds to shut the bike off. If you don’t hold it down long enough, the bike doesn’t shut down all the way and just goes into “standby” mode. When I would hop off and park the bike, I found myself just standing there awkwardly while holding the button and waiting for it to turn off before I could lock it and walk away.
China has experienced an explosive growth of sales of non-assisted e-bikes including scooter type, with annual sales jumping from 56,000 units in 1998 to over 21 million in 2008,[72] and reaching an estimated fleet of 120 million e-bikes in early 2010.[2][73] This boom was triggered by Chinese local governments' efforts to restrict motorcycles in city centers to avoid traffic disruption and accidents. By late 2009 motorcycles are banned or restricted in over ninety major Chinese cities.[72] Users began replacing traditional bicycles and motorcycles and e-bike became an alternative to commuting by car.[2] Nevertheless, road safety concerns continue as around 2,500 e-bike related deaths were registered in 2007.[73] By late 2009 ten cities had also banned or imposed restrictions on e-bikes on the same grounds as motorcycles. Among these cities were Guangzhou, Shenzhen, Changsha, Foshan, Changzhou, and Dongguang.[72][73]
Swift Folder - here's another folding bike option for those who want a good, fast folding bike at a reasonable price. Swift Folders are manufactured in Brooklyn with the New York City rider in mind. All Swift Folders are made to order, but models can range from 22-30 pounds and a typical Swift Folder costs around $750. It quick-folds in 10 seconds to a size that will get you onto most elevators. It folds down to 32" X 22" X 11" in about a minute, making it possible to put it into a duffle bag that you can use to tote it around in an inconspicuous manner (hint: we know of no elevators in which duffle bags are prohibited!). Swift Folders are available at various New York City area shops including the Hub, Bikeworks, and Recycle-a-Bicycle, where less expensive versions are featured (made with some used parts). www.swiftfolder.com, 1-800-884-5541.
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.
