In September 2017, Brompton announced that it was enacting a voluntary recall. Bikes with the third-party-manufactured FAG Bottom Bracket axle have been largely reported to fail—at a higher-than-expected rate. Any model (S, M, P, or H) with a serial number from 1403284144 to 1705150001 that was manufactured between April 2014 and May 2017 could be affected. Although the failure isn’t life threatening and doesn’t compromise the quality of how the bike rides—at most the faulty axle would disrupt the ability to pedal—Brompton has issued an apology and is offering free bottom-bracket cartridge replacements. You can find out if your bike is affected by checking the serial number, which is imprinted on either a silver sticker or a curved plate attached to the bike frame.
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.
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]
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.

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.

MIT graduate David Montague launched his folding-bike business in 1987 and counts the US Marines among its previous clients. The Massachusetts-based company offers a wide range of full-sized folders, but we went for this entry-level model for its stripped-back simplicity. The smart choice for commuters with longer journeys to the station (or those who simply have issues with smaller bikes), the 10.8-kilogram Boston comes in 17- or 19-inch frame options, with 700c alloy wheels, which allow for steady, speedy riding over medium distances. The folding system – essentially a bi-fold but for full-sized bikes – does a great job crunching the size down to a reasonable 90cm x 48cm x 30cm for stowing on trains or car boots, but the front wheel needs to be removed – albeit via a quick-release system – which delays the process by a few seconds.
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.
This is list of the best performing, best value electric bikes for 2017 / 2018. For each category I list two models, the first recommendation is based on performance and the second is based on affordability. As you explore the list and get to know EBR, check out the ebike community forum for more personalized feedback.

Lightweight folding bikes: Of course, if you intend to be hoisting the bike on and off trains, then it’s understandable that you want it to be light. This can be achieved though using a lighter frame material. Brompton have recently introduced titanium to their range and there are brands making carbon folders. Higher quality components will also reduce the weight, as will opting for fewer gears – such as a singlespeed version – but this will only really suit someone who doesn’t intend to come across many hills in their use of the bike.
The Mate X I rode is not a quiet bike. It sounds the way it looks: loud. On flat pavement, the drone of the 750W motor was louder than the 250W bikes I’m accustomed to riding on the streets of Europe (750W requires a license here, but not in the US) and the knobby treads only added to the din (you can opt for quieter street tires). Off road, the tires go quiet, but the sound is replaced with chain slaps and some creaking from the (optional) rear fender. While the knobby tire and motor noise isn’t likely to change, the company assures me that the final bike will ship with a tighter chain and silent rear fender.
I am 6'1" and weigh about 240. I got a bit over 6 plus continuous miles on a full charge on rolling hills. If you are using them as a form of transportation around towns as we are, I would do some experimenting on how much distance you get per charge in the type of terrain you are riding. Based on the load and terrain it is in line with what I expected. With a bit of planning they do the job. Maybe at some point they will add a conversion kit to ... full review
If an electric bike can get you to work without sweating through your shirt, and a folding bike can fit in a car and get stored under a desk, why not...an electric folding bike? Jetson’s Metro electric folding bike fits a 250-watt CZJB motor cleverly hidden in the bike’s crossbar. At $800, it's much more affordable than, say, a $3500 Tern Vektron or even a $1700 RadWagon RadMini.

Let's start with the obvious; you prefer a folding bike because you don't have space. Maybe you lack a lot of space at work, or you live in a tiny apartment. In fact, if you live in a tiny apartment that is located in a walk-up, then you probably know just how insane it is to lug a bike up and down several flights of stairs. If any of these conditions apply, you should probably own a folding bike.

Somehow, despite my original aversion to pedaling, I soon realized I was actually having fun using my legs. I even started dropping the assist level down from 8, the highest level, to a more reasonable 5 or 6. I could feel that I was making an honest effort, but it was just enough to get those endorphins going without being so much that I was sweating and tired.

Folding bikes are often uncomfortable for taller riders. Not so with the 3OND. The seat and stem can extend far out of the bike, accommodating all but the tallest people. As always, be aware of extending the stem too far. You do not want to stress the cables when turning. Adding to the comfort is a basic suspension fork. Although you cannot adjust the rebound or preload, it does have a lockout option.


Is it light enough? Make sure the folding bike you choose is light enough for you to easily carry around. Granted, you’ll be riding it much of the time, but you may have to hold it while on public transit or haul it up the stairs to your office or apartment. Some of the lightest folding bikes weigh under 10 pounds, but notably, they tend to cost more.
Obviously, you shouldn’t ignore traffic rules and try to weave around cars – that’s dangerous, even for unpowered bicycles. However, folding electric bikes can fit places that cars can’t – alleyways, or even sidewalks – though again, you should follow all posted laws and regulations about where to ride them. Using your surroundings smartly in an urban environment can help you avoid traffic completely.
The E-mazing Innovations e-bike goes about 15 miles per hour and has both throttle and pedal assist modes. It features instant fold option that allows you to fold the bike into a compact size in just a few seconds. Because it’s lightweight, you can easily bring it upstairs, in your car trunk, or wherever you need. With its unusual design, you’ll attract attention anywhere you go. The bike is one of the most stable models on the market, and it’s because of its tires and maximum speed. If the bike were to go faster, it probably wouldn’t be as stable. The motor and battery that power the bike are the 8Fun front-mounted geared hub motor, and a 9ah, 324wh Samsung 36V lithium-ion battery. You can go about 30 miles once you fully charge the battery for which you’ll need 5 hours. This folding electric bike features an LCD that shows battery life, a kickstand, and fenders to keep your pants clean and dry. Keep in mind, though, that the bike features some unusual parts that are much different than those you find in standard models. This isn’t a deal breaker, but keep in mind that for this reason, some parts may be hard to replace if need be. All in all, it’s attractive, modern and well-made to last you a long time.

This is actually the number one thing stopping many people from riding bicycles to work – if it’s hot outside, nobody wants to be sweaty when they get to the office, especially if they have no place to shower. folding electric bikes allow you to minimize the work done on the bike when you need to in hot weather, and keep you feeling fresh and cool even during the hottest commutes.


bike design refers to the ideation and development of two-wheel, human-powered, pedal-driven vehicles, and their use across various aspects of our lives -- from leisure to sport to basic transportation. bicycles can take on a variety of frame geometries, rendered in a diverse range of materials such as aluminium, bamboo and carbon fibre; and include hybrid and electric versions.
