The Dahon Qix D8, a higher-end model than the Mariner D8, folds in half like a switchblade (end over end), and you can orient it the standard way (seat up) or upright, with the frame hinge up; with the bike in the latter position, you can roll it. In our tests, everything about the Qix D8, from ride to storage, was just fine, but unless you’re in love with the interesting fold, you may be better off putting your $1,000 toward a Brompton or a Birdy, or saving nearly half of that by buying the Mariner D8.
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.
Some manufacturers are producing folding bikes designed around folding systems that allow them to use 26" wheels, e.g., Dahon, KHS, Montague, and Tern Bicycles. Advantages of smaller wheels include potential for more speed, quicker acceleration, greater maneuverability, and easier storage.[10] For example, the A-bike is similar to the Strida but has tiny wheels and folds a bit smaller. Bikes with smaller than 16" wheels are often called portable bicycles. These forgo the performance and easy ride benefits of their larger counterparts, acquiring characteristics similar to those of an adult folding kick scooter. Nonetheless, regardless of how each bike folds, the result is easier to transport and store than a traditional bicycle.[11]
Beach cruiser fans rejoice with the Raleigh Retroglide iE Step Thru. Cruise the boardwalk with maximum style and minimum effort as you enjoy the perks of a 350 watt motor and a top pedal-assisted speed of 20mph. Enjoy the comfort of an upright riding position thanks to the backswept handlebar and take advantage of the cargo-carrying capacity, thanks to the rear rack, to run errands around town or commute to work. With a claimed range of 35 miles, the Raleigh Retroglide is a great choice for anyone who wants to add a little speed to daily cruise.

Folding commuter bikes have never been more popular with workers keen on keeping fit and avoiding urban public transport. Where just a few years ago the choices were confined to a few heavy models that swung around a clunky hinge, there are now a range of appealing versions for many needs: full-sized, tiny, electric, sporty, cruisers... the choices are near endless.
Designed specifically for travel, the Breakaway is a full-sized road bike frame that splits in two for easy packing. Ritchey uses high-quality butted cromoly steel for the frameset, which features an efficient road riding geometry and carbon fork. A locking compression system ensures the joints won’t come apart while you’re riding, and only adds 100 grams. The Breakaway weighs 5.2 pounds and is available in five sizes. Ritchey also includes a travel-ready packing case. Build it up to suit your traveling road cycling dreams. Price: $1600.
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 also had long discussions with my editors about price versus value. A number of companies sell very inexpensive folding bikes on Amazon and at big-box stores such as Target and Walmart. However, because a rider’s life could quite literally be at stake should their bike suffer a mechanical failure mid-ride, we suspected that most people would prefer to spend a little more for a known brand with a reputation to maintain. We did call in Amazon’s best seller, a $200 Schwinn, as well as a couple of other mass-market bikes that had good reviews from other editorial outlets. On the other end, we considered a few pricier picks for more serious riders who are willing to shell out for higher quality or extra features. Finally, with the established producers (Dahon, Schwinn, and Tern), we looked at both an entry-level model and an upgrade version. Our final list:

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.
The interesting part of the pedal assist system in the Oyama is that it can really sense when it is needed. The hardest part of pedaling is starting from a dead stop, and that’s precisely when the pedal assist was providing the most power. I could feel it start to taper off as I passed through 10 mph (16 km/h) or so, but by that point I had sufficient momentum that I only needed a gentle boost from the motor to help maintain higher speeds.
Dahon - a full 60% of all folding bikes sold in the U.S. are made by Dahon. A quick survey of NYC bike shops shows that just about everyone is selling them. One particular model seems to stand out: the aluminum-framed Presto that weighs in at just 20 pounds, making it the lightest production folding bike in the world. Its folded dimensions are 28" X 20" X 11" (with 16" wheels). The Piccolo (based on the Dahon Classic, a very popular older model) has similar dimensions but a steel frame that makes it weigh in at 26 pounds. In addition to other 16" models, Dahon also offers many other attractive models of folding bikes with 20" and 26" wheels that fold into larger packages and offer better performance and ride. Prices range from $200 for a simple 20" wheeled model to $900 for a full-size mountain bike. Dahons fold in about 15 seconds. www.dahon.com (Bikes can be ordered through many local bike shops or from B-Fold, www.bfold.com, 212 529-7247).
The Mate X, like the original, can be folded completely in about 10 seconds. That can be a huge convenience for many urbanites since you can pack it in the car or take it on public transport where folding bikes are often allowed free of charge all day long (in Amsterdam, there’s a €6.20 surcharge for regular bikes and they can only be taken on trains during off-peak hours). You can also just fold the handlebars and pedals if you need a thin profile to store the bike in a narrow hallway, a wall rack, or to roll it into a busy elevator. But don’t underestimate the weight or the size of the Mate X. At 29kg (64 pounds), this bike is heavy, and it can be unwieldy to lift because it doesn’t lock into the folded position.

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]
Folding bikes are set apart from other machines on the market by one defining characteristic: they fold. The collapsable nature of these bikes means that they’re ideal for anyone who wants to cycle to a train station, and take their bike with them for the journey into the unknown on the other side (or the standard 2 mile radius from London Bridge).
Come for the price, stay for the awesome. The August Live! LS is one of the lower-cost e-bikes you’ll find. What it lacks is gadgets it makes up for in flare and retains just what you need. You won't find a digital display or integrated lights, Instead you get trendy, chopper-style handlebars, a sweet paint job, and a 250 watt motor that is more than capable of tackling steep hills without a second thought. That said, this bike just begs to be ridden on casual cruises down the boardwalk or bike path.

Montague - this maker offers only full-size folding bikes that are fairly light (around 30 pounds) but have correspondingly large folding sizes (36" x 28" x 12") Prices range from $395 to $645, and a soft carrying bag is an option. If you are looking to avoid the small wheels of some brands and perhaps want a good full-size bike that just happens to fold, this may be a good choice. Montagues fold in 30 seconds without tools.
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.

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.
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.
