Now bicycles are becoming more relevant. In large cities, infrastructure is developing, thanks to which they can safely move. For some, two-wheeled transport becomes the main one, replacing cars and buses. Therefore, there are a lot of developments in this area. Something new is constantly being invented. One of these innovations can be considered a bike without spokes. Why is it needed and what are its features?
Kinds
The metal rim, spokes and hub are the main parts of each wheel. Such a system has been tested for centuries. It is quite durable and reliable. But the engineers decided to challenge the classics and create something new - a bicycle without spokes in wheels.
There are several different types. Each of them differs in its features and has different characteristics. One of the most common non-spoke bicycles is the alloy wheel bike. Little known, but no less surprising - with wheels on elliptical ribbons. The top of this top is actually a bike without spokes. More details about each of them will be a little lower.
Alloy wheels
The main feature of such a rim is integrity. He does not understand. Instead of the most ordinary knitting needles, here are the blades that also connect the rim and the hub. The wheel is cast from one material. Most often it is an aluminum alloy.
Initially, such discs were placed only on sports models. The special shape gives the design better aerodynamic performance. After some time, they began to appear in the public domain. Now they can be purchased at many sports stores.
They are made using special technology, under great pressure. So the part is strong and homogeneous, without any defects.
Pros and Cons of Alloy Wheels
Everything has its positive and negative sides. Alloy wheels have both. Of the advantages, you can immediately distinguish:
- Custom appearance.
- High aerodynamic performance.
- Models do not require any maintenance.
The first thing that ordinary cyclists loved them for was, of course, a very beautiful design. Such a detail is hard to miss. Typically, these discs are still painted in various bright colors. So with them you can easily stand out from the gray bicycle mass.
Thanks to its streamlined shape, the air resistance is reduced. This means that you need to put less effort.
The design is quite rigid. She cannot be deformed. Therefore, small blows can withstand. But from here some minuses also appear:
- A lot of weight.
- The model is not repairable.
- High price.
Elliptical Wheel Wheels
This is such a design where instead of standard knitting needles, rolled strips of carbon fiber are used. They are twisted into an ellipse and fastened on one side to the sleeve, and on the other to the rim. There are 3 tapes per wheel. They have very good cushioning capabilities. Their only minus is a bad roll. Due to insufficient hardness, a lot of energy goes into depreciation. Therefore, acceleration on such wheels does not work well.
Nulla - a bike without spokes
Minimalism and futurism - this is how you can put it about this bike. Nulla is the latest development in the bicycle industry. The developers tried to completely remove the knitting needles and sleeve. From the old design, only the rim remained.
The wheel acts as a big gear. The legs move the sprocket, which interacts with the rim on which the notches are applied. Therefore, this bike does not need a sleeve.
It looks very elegant. It seems that this is some kind of aggregate from the future. The exact price of a bicycle without spokes in wheels is not yet known, since it is still under development. Engineers need to solve a few more problems with the brakes and transmission. But soon such a miracle will be able to go on free sale.
