Folding electric bike. Light electric bicycles Who has the right of way when crossing an intersection with a bicycle path
It has a huge impact on the dynamics of its acceleration and ease of pedaling, however, when purchasing, many beginners pay insufficient attention to this factor. Usually they buy a bicycle, flattered by the bright appearance, an attractive price or seemingly advanced equipment. This is especially common among parents who choose the first adult bike for their grown-up children. As a result, you can often see a child trying in vain to gain speed on a heavy structure with two suspensions made of thick steel pipes, although this task is impossible even for physically strong men. This often leads to bitter disappointment, and the two-wheeled horse moves to the farthest corner of the garage, where it gathers dust until it is sold to another amateur or scrapped. To understand what weight will be optimal for certain cases, you need to consider the main popular options.
Sports bikes
The heaviest element of a bike is its frame, so materials are used to ensure the necessary structural strength with minimal weight. For a long time it was alloy steel, then it was replaced by aluminum and titanium alloys, and in recent decades carbon fiber has become the undisputed leader.
Record-breaking professionals
The lightest bikes are used in road and track racing, where everything is about achieving maximum speeds. Here the struggle is literally for every gram. For example, the TrekEmonda SLR road bike, named “bike of the year” by many publications in 2014, weighs 4.65 kilograms, of which the frame weighs only 690 grams. However, this record did not last long, and the following year it was pushed off the pedestal by the Scultura 9000 LTD, which claimed the title of the lightest production bicycle in the world. Designed by Taiwanese giant Merida, this bike's frame is just 10 grams lighter.
But this is not the limit, since after Merida, SCOTT announced its new development– Foil 2016 with a 610 gram frame, which debuted in last year’s Tour de France. It is worth noting that heavier versions of these models take part in the competition, since according to the rules International Association Cyclists (UCI) limit the minimum weight of sports equipment for official racing to 15 pounds.
In the meantime, the record holder remains FairwheelBike's SpinLight - the lightest bicycle in the world, which made a real splash in 2010 at the International Bicycle Expo bike show in Las Vegas. Almost all of its parts are made of carbon, and the weight is an incredible 2.7 kilograms. The cost of this exclusive road bike is 45 thousand dollars.
SpinLight is listed in the Guinness Book of Records as the lightest bicycle in the world
It is made only to order, and it is unlikely that you will be able to see it at competitions, much less on the roads.
Mountain bikes
All the bicycles listed above are real masterpieces of technical thought, but their high price makes them inaccessible to the average consumer. Moreover, the rationality of using super-light bicycles in everyday life raises serious doubts, and when choosing a bike, it is worth considering more affordable options, the most popular of which is mountain bikes.
Mountain bike has a large number of subspecies, its design and weight largely depend on what style of riding you prefer. For example, strength is paramount in downhill, while cross-country requires a lightweight frame. If you need an entry-level or mid-level bike for the city and infrequent outings, then the choice is most often limited to two options: aluminum or alloy steel. Although titanium alloys are characterized by high strength and low weight, they are too expensive for such bikes. Chrome-molybdenum steel is reliable, most durable and has excellent maintainability, but is heavier than other materials. Therefore, you should opt for a bicycle with an aluminum frame, since this particular metal has sufficient rigidity with low weight and an affordable price.
Omega Women's Mountain Bike
The women's mountain bike deserves special mention. Usually a women's bike has a lowered or curved top tube, but in extreme disciplines the bicycle frame is subject to increased loads, so changing its geometry is unacceptable. However, many manufacturers include in their range products that are positioned as mountain bikes for women. Such projectiles are practically no different from ordinary ones, but have a number of features: a narrowed steering wheel and front triangle of the frame, shortened connecting rods, and also the most reduced weight. These properties are designed to provide women with the greatest comfort when sitting and riding, however, many experts consider the appearance of such bicycles to be only a marketing ploy on the part of manufacturing companies designed to increase sales.
Potential leaders
When choosing a light and comfortable bike, it is worth considering two interesting options, which are very often and completely undeservedly overlooked. The first of them is a hybrid that combines the best qualities of road and mountain bikes, which allows the rider to feel confident on any type of surface. Relatively low weight, large wheels with a diameter of 28 inches and a fairly high seating position provide optimal riding comfort.
The second option is a cyclocross bike. These bikes have a rigid fork and curved handlebars, so they are often confused with a racing road bike. However, cyclocrossers are equipped with tires with a wide aggressive tread and frames with extended stays. They are much lighter than a hybrid or mountain. On average, their weight is 8–10 kilograms, which allows you to quickly pick up speed and also easily carry the bike on your shoulder. On asphalt they are almost as good as a road bike, but at the same time they retain the ability to ride on rough terrain. Despite its many advantages, a cyclocross bicycle is still rarely seen on the roads of the former USSR, although it is very popular abroad.
City bikes
A city bike is a bicycle that is perfect for the city. Everything in its design is aimed at providing maximum comfort. equipped with a soft, comfortable saddle, a chain with protection and a high handlebar. Very often they are equipped with a rear hub with a planetary gear. As a rule, city bikes use frames with a curved top tube or no top tube at all, which makes it easier to fit in casual wear and makes it ideal for girls, as it can be ridden in a skirt.
It's great for leisurely riding in urban environments, but can hardly claim to be the lightest bike in the world. The main purpose of such a bike is to serve as an inexpensive and practical means of transportation on city streets, so it cannot be used as sports equipment. However, when choosing, you should pay attention to the weight of the bike. A bike with an aluminum frame is preferable, because it is much easier to ride.

Small, but remote
Those whose childhood and youth passed in the Soviet Union remember the concept of a “folding bicycle” with nostalgia, because for most of them it was the first “adult” bike.
The names “Minsk”, “Desna” or “Salyut” mean little to the new generation, but at one time such a bike was an unattainable dream for many, because it cost almost a month’s salary of an ordinary engineer. A very heavy frame made of thick steel pipes, one gear and a foot brake - this was the Soviet folding bicycle.
But those times are long gone. Modern folding bicycles are radically different from their predecessors. In their production, progressive technical solutions and modern materials are widely used. The advantages of such bikes are their small size when folded, ease of storage and the ability to be transported on public transport. The super-compact A-bike, invented by Clive Sinclair, weighs only 5.7 kilograms. This aluminum baby fits easily into a regular backpack and costs just £300. Another record holder - Strida - has disc brakes, a planetary hub and weighs about 9 kilograms. Another feature of this bike is the replacement of a conventional chain with a drive belt that does not require lubrication.
Strids EVO with three speeds
A bicycle gives you a feeling of freedom comparable only to hang gliding, but excessive weight can ruin the pleasure of the trip. When purchasing a bike, you should pay special attention to this issue. The ideal solution The device may be assembled according to an individual project that best suits your needs. However, you shouldn’t get too carried away with making your bike lighter. Any cycling forum is already crowded with people who are chasing the lightest possible components, forgetting that a bike is primarily intended to be ridden.
Electric bicycles appeared on the transport market relatively recently, but today they are already one of the most popular means of transportation in big cities. There are no traffic jams, you can drive through courtyards and parks, and a kilometer of travel costs practically nothing (within a penny!). The advantages are more than solid, but ordinary bicycles also have them. Why are they bad?
In fact, practically nothing, except for one serious drawback: if you pedal, you sweat. It’s good if at the destination there is an opportunity to take a shower or change clothes, but what if you need to get to work, for example? To the club? Finally, to the shopping center. I don't want to walk around dirty at all. This is where electric bikes come to the rescue and do all the work for you.
True, they also have their drawbacks. One of them is weight. Naturally, the motor and battery make the vehicle heavier, which means it is more difficult to carry, it is more difficult to control, it is more difficult to accelerate... But they have already learned how to solve this problem.
The lightest electric bicycles
These are models that weigh 15-17 kilograms - only slightly more than professional bicycles without a motor. Weight reduction is achieved through the use of more modern materials and equipment, that is, without compromising quality and performance. Of course, the greater the range and engine power, the greater the weight, but each class has its own leaders - both not heavy and fast!
The lightweight electric bicycles that we offer you are equipped, among other things, with a folding mechanism: they are convenient to store and transport. Perhaps this is the most ergonomic city transport that exists!

Sometimes you really want to go for a bike ride, but don’t stress yourself out. So that you can quietly but happily walk on a bicycle that moves independently from one given point to another, and the driver just needs to turn the steering wheel. Or make short runs to the store and back - he doesn’t get into the car for a couple of kilometers. And how many people in traffic jams dream of being able to easily get to work and not sweat like after gym. It was for such people that the first electric bicycles were created. The lightest of them have become the standard, because for their owner, the weight of an electric bike sometimes turns out to be the most important factor.
Top Five Electric Bikes
Lightweight and space-saving, e-bikes are designed for the convenience of the owner. They are designed for those who want to get to work faster through traffic jams. It will be used with pleasure by those whose physical form It also leaves much to be desired for those who want to go to work by bike, but are afraid that the lack of a shower will prevent them from working successfully. For those who want to buy a good and high-quality electric bike, but don’t know where to start, here are the five most best models this type:
Where to buy?
There are not many places to purchase these inventions. You won't find them on the market for regular bicycles, and you won't find them in every specialized store. But where to look for them? You can try to get around the large sports stores in the city, sometimes they have one copy or they can pre-order. Another good option is the manufacturer's website. In addition to the bike itself, they will be able to provide you with quality assistance in selecting accessories and additional body kits for it.
Forums for those interested are sometimes decorated with advertisements for sale. But purchasing an electric bike from someone else is not the most good idea. You should only buy a product from someone else if you are completely confident in the quality and integrity of the seller. Common cause What makes a sale is not a simple device, but its implicit breakdown, so it’s worth taking a good look at it before you take out the money. But the price for such a bike is usually much lower than for a new one.
Intrusive service from operators who persistently impose paid subscriptions creates a feeling of irritation and hopelessness in customers, especially when such a “service” eats money out of consumers’ pockets. The best option There may be a legislative ban on the provision of such services, but it is known that cunning businessmen always... Read more
