As for tech specs, the Mariner D8 comes with a forged aluminum crank (according to our experts, more long-lasting than the pressed/riveted steel or aluminum that manufacturers sometimes use to cut costs) and a Shimano Altus rear derailleur (an upgrade to the Tourney on the previous D7 model), which offers good quality for the price. The D8’s tires, Schwalbe Citizens, are about on a par with the just-okay Kenda Konversions seen on the D7. Finally, and possibly most telling, our cyclist testers gave the Mariner D7 a unanimous thumbs-up, saying it “felt most like a real bike.” Although they weren’t able to test the D8, I was, and the ride quality hasn’t changed.

I also know people. To research this guide, I consulted with David Lam, owner of Bfold, a folding-bike shop in Manhattan that carries Bike Friday, Birdy, Brompton, Dahon, and Tern, among other brands; Steven Huang, a consultant for Birdy and Brompton and the owner of Foldie Foodie Brommie Yummie riding food tours, also based in New York City; Stephen Cuomo, a folding-bike industry consultant in Connecticut and founder of Biketube; general bike expert Damon Strub, owner of the Astoria, New York-based Nomad Cycle (which carries Dahon), who answered all my annoying technical questions about derailleurs and hubs; and our very own Mike Berk, executive editor of The Wirecutter and a longtime folding-bike enthusiast. I also recruited eight cyclists—ranging from recreational to competitive, and including males and females of various heights—to test-ride the bikes and provide their thoughtful feedback.
Range is a key consideration with e-bikes, and is affected by factors such as motor efficiency, battery capacity, efficiency of the driving electronics, aerodynamics, hills and weight of the bike and rider. Some manufacturers, such as the Canadian BionX or American Vintage Electric Bikes, have the option of using regenerative braking, the motor acts as a generator to slow the bike down prior to the brake pads engaging. This is useful for extending the range and the life of brake pads and wheel rims. There are also experiments using fuel cells. e.g. the PHB. Some experiments have also been undertaken with super capacitors to supplement or replace batteries for cars and some SUVS. E-bikes developed in Switzerland in the late 1980s for the Tour de Sol solar vehicle race came with solar charging stations but these were later fixed on roofs and connected so as to feed into the electric mains. The bicycles were then charged from the mains, as is common today. While ebike batteries were produced mainly by bigger companies in past, many small to medium companies have started using innovative new methods for creating more durable batteries. State of the art, custom built automated precision CNC spot welding machines created 18650 battery packs are commonly used among Do-it-yourself ebike makers.
I unboxed, assembled (if needed), adjusted, and assessed each bike for my initial impressions, taking them all on a short first ride around my neighborhood in Queens. In a few cases, the bikes needed more extensive adjustments, for which I brought them to Nomad Cycle in Astoria; if you buy a bike online, you should bring it to a mechanic for a once-over, no matter what.
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.
We spent 44 hours on research, videography, and editing, to review the top choices for this wiki. Today's folding bikes can offer the ride quality and durability of standard bicycles, but with the added benefit of total portability. The fact that they are foldable lets you take them places you could never reach by pedal power alone, as you can stash them in your vehicle’s trunk or carry them onto a bus or train. Some are even equipped with batteries to give you an even greater range. When users buy our independently chosen editorial picks, we may earn commissions to support our work.

Mate Bikes is a small brother-and-sister company based in Copenhagen that has raised over $12 million on Indiegogo since 2016. First they collected $6.8 million for the skinny original. Now they’ve raised close to $6 million more for the beefier Mate X, a laughable 11,785 percent beyond its funding goal with five days still to go in the Indiegogo campaign. Mate Bikes has no outside investors although that’s likely to change soon, the company tells me.
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
Many folding frames follow the classic frame pattern of the safety bicycle's diamond frame, but feature a hinge point (with single or double hinges) allowing the bicycle to fold approximately in half. Quick-release clamps enable raising or lowering steering and seat columns. A similar swing hinge may be combined with a folding steering column. Fold designs may use larger wheels, even the same size as in non-folders, for users prioritizing ride over fold compactness. Bikes that use this kind of fold include, Dahon, and Montague, and Tern.
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.
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.
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
Electric bikes are here in a big way. Liberated from some of the normal constraints of standard bike design like weight and gearing, e-bike design has exploded; if you can imagine it, someone has built it. From cargo bikes to city bikes, messenger bikes to mountain bikes, road bikes, and even beach cruisers, there is something for everyone. The beauty of e-bikes is they make the joy of cycling accessible to so many people in so many ways.
E-bikes are classed according to the power that their electric motor can deliver and the control system, i.e., when and how the power from the motor is applied. Also the classification of e-bikes is complicated as much of the definition is due to legal reasons of what constitutes a bicycle and what constitutes a moped or motorcycle. As such, the classification of these e-bikes varies greatly across countries and local jurisdictions.
