Your long bicycle commute to work means you are a sweaty mess before the day even begins, and you have never felt at ease leaving the bike locked outside the building all day, but now that you have a folding electric bike, both of these problems are solved. The electric bike assists you at the hardest parts of your ride and keeps you flying safely down the road at up to 20 miles per hour or faster, without pedaling. Its folding design then makes the bicycle so compact, you can fit it in a corner of the office without disturbing anyone. The large selection on eBay includes folding electric mountain bikes as well, for easily traversing more rugged terrain and in less than perfect weather. Folding electric bikes are safe, efficient, and fully rechargeable. Some brake systems turn the motor off automatically, which saves power. Brushless, gearless motors function quietly, which is more pleasant both for the rider and nearby pedestrians. Electric bike conversion kits are also available to help you install an electric bike motor onto a compatible standard bicycle.
I then rode each bike on a test commute into Manhattan and schlepped it back on the N train, taking note of the shifting, steering, braking, and overall ride quality, as well as the ease of folding the bike and then carrying it down the subway stairs, through the turnstiles (not all fit), and onto the train—and then doing the reverse on the other end. I also evaluated any luggage-/cargo-carrying options, as well as how compactly and securely each bike folded for fitting under a desk or into a car trunk or closet.
For anyone familiar with the folding-bike category, it may not come as a surprise that a Dahon—the Dahon Mariner in particular—topped our tests and emerged as our pick for most people. Founded in Southern California by David Hon 30-plus years ago, the company lists 18 current models on its site, from basic grocery-getters to step-through beach cruisers to high-performance bikes.

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
Your embark is more than a bike – it's a healthy alternative to traffic, hills, parking and sweat. 65% of riders use their eBike to replace their car. 66% said that they preferred an eBike because of hilly terrain near work or home. Nearly 75% rode their eBike to different destinations than their standard bike. The Embark brings your destinations closer and expands your world - all with simplicity and reliability.
The Metro has front and rear disc brakes, and a guard to keep your pants from getting caught in the chain. It only has one gear, but it capably made its way up a 20-degree hill near my house on level 3 assist. The display measures how much battery you have left, depending on how hard the motor is working, but I found its accuracy suspect. It's a little disconcerting to see the battery level fluctuate so rapidly. Wait, do I have 51 percent battery, or 14 percent? Only time will tell!
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]
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.
Controllers for brushed motors: Brushed motors are also used in e-bikes but are becoming less common due to their intrinsic lower efficiency. Controllers for brushed motors however are much simpler and cheaper due to the fact they don't require hall sensor feedback and are typically designed to be open-loop controllers. Some controllers can handle multiple voltages.

Another exceptional vehicle namely Ferty folding 36V electric moped bike is here to excite your rides. Its frame consists of aluminum alloy whereas its wheels are made of double alloy material. Ferty folding sports bikes battery recharges quickly and takes up to 4-6 hours. There is an adjustable seat that ranges from 80 to 90 cm, appropriate for bikers with a height range of 165 to 185 cm. The folding sports mountain bike has the transmission of Shimano with the speed of 21. It ultimately gives the smooth ride on different kinds of terrains.

 You will be very comfortable riding this bike. Both the handlebar and seat height are adjustable and you can get the seat very high, which is an advantage for taller riders. The swept back handlebars give you a relaxed riding position. Thanks to the low frame, it is easy to step onto the bike. Adding to the comfort, and total weight is a basic suspension fork to take the sting out of potholes.
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.
All around the world, the way we get from A to B is changing. With the world on the verge of auto-mobility, driverless cars, ride-sharing, and the mainstream arrival of electric vehicles, it’s an exciting moment for transportation. To help drive this force of change, we developed a small collection of electric bikes that take hills, headwinds, traffic, and bike thieves out of commuting. Explore below.
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.
Another Kickstarter creation, the A-bike features an innovative design that sees it sporting quite possibly the smallest wheels you’ve ever seen on a bike. The makers claim that normal efficiency is maintained thanks to a dual chain drive and brushless motor that’s been optimised so that rate of pedalling matches the speed at which the wheels turn.

The other standout feature is the front luggage system, which allows you to clip a number of well-designed bags from Brompton and other makers to the front of the bike; the bags can even hang out there (albeit a bit awkwardly) when the bike is folded. (This last feature, which allows you to roll the bike when it’s half-folded and use it as a shopping cart, works better if you have Brompton’s basket bag attached, rather than a touring-style bag.) We’ll look more closely at both Tern’s and Dahon’s front-carrier options for a future update.


I liked everything but I have two concerns. 1) I bought two bikes. One for me and one for my friend and already on the first week both biked got problems with the brake handle. One of them broke without any reason. But both are really bad and doesnt work properly. 2) we need to buy an extra battery and it is always sold out. We really need it and we can't find. But overall the bike is excellent. I don't know how to replace the brake handle.

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.
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]
According to Bike Friday, the New World Tourist will fit into a Samsonite F”Lite GT 31 suitcase, and will accommodate front and rear racks for panniers, as well as a trailer. Bike Friday offers the New World Tourist with multiple drivetrain options and disc brakes. There is also a belt-drive version with an internal shifting hub. Builds start at $1300.
The hydroformed aluminum frameset features sleek lines, and SRAM XO and Force components comprise the drivetrain. A carbon crank from FSA ensures efficient power transfer and keeps the weight down. The wheels feature straight-pull spokes and deep-dish rims for aerodynamics. Tern uses a simple three-step folding process, and the bike can roll when folded for easy transport. Price: $3000.
I just received my Swaggy Bike and was so exited, I had delusional grandeur thinking of all the places in proximity I can actually visit on Google map. It came packaged with instructions however, I used every curse word in the book trying to get the seat installed. Thanks to the video Jack posted on here, I was able to stop and restart watching 5+ times and see how he went about the whole process. I glared at it while it was charging and even thought I'd get on for my neice. Then...the moment of reality kicked in. I made sure to READ the manual front to back being that I spent an insane amount of money for this particular model...Took it for my first spin, and the rear tire popped off the real well??So.....I called the toll free number and was greeted by a less then concerned Rep in ... full review
Its fold really is innovative. The rear wheel rotates under, the front wheel tucks into the side, and the handlebars fall sideways and lock into place—the typical fold-in-half frames of our other picks look clunky and huge by comparison. (The larger wheels don’t help, of course.) The folded Brompton stands 3.4 inches shorter, and measures 2 inches narrower and 8.1 inches shorter front to back, than the Mariner—and the differences are even more dramatic when you compare the Brompton with the larger Tern models. If you want to tuck your bike under your desk or bring it into stores with narrow aisles, smaller is, of course, definitely better.
Another type of electric assist motor, often referred to as the mid-drive system, is increasing in popularity. With this system, the electric motor is not built into the wheel but is usually mounted near (often under) the bottom bracket shell. In more typical configurations, a cog or wheel on the motor drives a belt or chain that engages with a pulley or sprocket fixed to one of the arms of the bicycle's crankset. Thus the propulsion is provided at the pedals rather than at the wheel, being eventually applied to the wheel via the bicycle's standard drive train.
