With the large-scale application of solar cell membranes, Downing's long-ago invention of the Round Table Rider bicycle ushered in a revolution - equipped with sails. The original annual rent of one euro became zero. 5 euros, while the price after adding this accessory is still 1 euro.

The sail, covered with a perovskite-structured solar cell, is one meter long and five meters high, and is divided into five layers, each measuring 1 meter. When folded up, it's a 1 x 1 meter thing. When the riders want to go far, pull the "Sail" button on the handle of their right hand and the sail behind them will automatically rise.

The sail uses small chips and sensors to automatically adjust the windward side to capture the maximum wind flow speed difference, and can be ridden at 15 km/h without solar power turned on under normal conditions (comparable to the foot strength of the average person).

When the road is relatively smooth, the solar drive can be turned on, and the speed can reach more than 30 kilometers. It's a great tool for commuting to work and going on a weekend outing. Young people who love to travel but don't have any money in their pockets are enthusiastic about this ultra-cheap "strategic travel tool".

In order to allow young people to ride without worry, the Rider of the Round Table also has a special off-road version, which has a tool set for inflating the bicycle, repairing tires, repairing chains and other common problems, only the size of half a bottle of water, placed at the lifting bar of the sail, without any sense of disobedience.

If you don't want to go on a long-distance trip, we at Knights of the Round Table have prepared a navigator for you for only half a euro. It resembles a small box that is able to attach to the handlebars of the bike. This navigator is so cheap because it is able to receive a "subsidy" from somewhere else.

The navigator still uses Downing's favorite projection technology, which can be transformed into a remote vending machine. When you are in the wilderness, you are most afraid of problems such as lack of water, food, or the clothes you wear are not warm enough, and the remote vending machine can solve this qiē.

There are 27,000 products built into the navigator, most of which are related to outdoor travel and exploration. There are tents, clothes, shoes, lamps, cooking utensils, food, spices, fishing gear, knives...... There is even a parcel delivery service, which not only collects parcels, but also sends your surplus and purchased items home at any time.

The Peregrine Falcon UAV of the Wind Bird Express Network will take on this Qiē field logistics mission. It seems that the travel expenses of the travelers are very small, only a bicycle, but most travelers will make various purchases on the way, and at this time they can only deal with peregrine drones, so the Windsor consortium can make quite a lot of profits from this humble bicycle.

One of these outdoor items is interesting – the inflatable catamaran Knights of the Round Table Edition. It's small and looks like two big clothes when packed, but when it's inflated, it instantly turns into two guys, and can be mounted under the bike to turn the bike into a catamaran.

The wheels of the bicycle are combined with a simple plastic propeller that can be driven by sails and solar membranes, and this is the bicycle version of the sailboat! When travelers see beautiful lakes and rivers on the way, they will definitely want to take a dip in the water on a sailboat more than ever, and Windsor has another opportunity to make money.

This amazing set is also cheap, with an annual rental of only 0. 1 euro, from now on the traveler can freely switch between shore and water, tsk, such a trip is really free to go free.

The topic of this "super touring bike" on the Internet is really lively in the outdoor community to the point of volcanic eruption. What does it feel like to be able to travel the world on a bicycle?

Since the delivery drones of the Wind Bird Network only pass within the territory of the United Nations, many Allied travelers are envious and jealous of the residents of the United Nations and want to betray the motherland.

The key here is that the operating cost of the UAV is ultra-low, because of the use of electromagnetic catapult scheme, the coincidental peregrine falcon UAV can be ejected to a height of 3000 meters, the result is that the peregrine falcon can fly more than 100 kilometers with zero power consumption, and when it is lucky, it can run out of more than 200 kilometers, which can meet most of the delivery range.

The distance between most network nodes is 120 kilometers, the average delivery distance of the package will not exceed 60 kilometers, and the energy consumption of the return journey is negligible, so most of the packages are free of post, what a happy outdoor free travel.

There are also some unexpected accessories invented by third parties, such as the "Bicycle Train Kit", which is a device that uses the self-balancing technology of solo to make the bicycle self-balancing, and its advantage is that the bicycle will never fall down.

At this time, the two bicycles are strung together with a rope, and only the rider of the bicycle in front is the driver, and the rider of the car behind can enter the "driverless" state. When everyone uses this technique, more than a dozen people can be strung together into a spectacular round table knight train in an open area, which is labor-saving and fun.

As soon as this method appeared, it was immediately uploaded all over the Internet, because everyone was posting photos of themselves and their riders in strings, as if they were competing which team was stringing longer. There is the longest string of world records, which is currently a large prehistoric grasshopper made up of 108 Knights of the Round Table.

In these years, if you haven't made a grasshopper on a long rope with others, you are not a senior traveler. This kind of game played by the children of poor families eventually affected all the travel class, and many of the local tyrants who could afford luxury off-road vehicles such as the jaguar joined the ranks of grasshoppers and became a trend.

Apparently, the merchant who invented the amazing creation was no longer satisfied with the grasshopper, and the merchant who invented this magical plaything soon introduced a novelty - the bicycle trailer. It turns out that some merchants have invented small trailers, but because of the lack of pulling force, they can generally only drag one master.

But now the world is very different, and the power of several bikes strung together is not inferior to Santa's reindeer sleigh. Merchants invented a large trailer capable of carrying four people, which only needed two full sails to pull when full, and its speed was 15 kilometers per hour.

And when the power source is increased to three bicycles, it is basically the same as those young people who string grasshoppers. This beautiful trailer allows travelers to drive a duì while traveling, three or four travelers get together, take turns to send one as a driver, and the rest two or three people can enjoy the car, train-like treatment.

And this kind of trailer car is also cheap, and the entry-level one is only 0 rental. 1 euro a year is available to all adults, not forgetting that adults over 18 years of age at the United Nations are entitled to an unemployment benefit of one euro per month. Travel is too beautiful and too cheap, many young people want to travel after they are tired of hard work when they first enter the society, and the bicycle trailer has become a very successful product.

Because of this excellent solicitation attribute of bicycle trailers, some residents of small towns have invented "taxis" that use them as tools, and Beijingers call them "three jumpers", which can operate at a very low cost and compete with real taxis.

Especially when it comes to long-distance transportation, our tripods don't consume energy at all.

Of course, these grassroots drivers can't use two or three bicycles at the same time, they rent the bicycles back and remove the sails of one of them and install them on a large trailer, so that a bicycle has two sails, enough to pull two guests to fly, if there are really four guests, they can only take their time (15 kilometers per hour), maybe the boss has to pedal hard, it looks a little weird, but who told you to be greedy?

Both Knights of the Round Table made a fortune, but instead of being jealous of them, the Knights of the Round Table developed a "mountain bike" for poor travelers. The mountains here refer to real mountains, mountains where there are no roads. It uses paragliding technology, which allows the mountain bike to reduce friction with the ground at very little speed.

It's quite like walking with the gravitational pull of the moon, and no rough or difficult ground can make such a mountain bike difficult. Its hub is not round, but is composed of radial supports inlaid with rubber axles, with highly elastic springs, completely ignoring the obstacles such as large stones, wood, and grass on the road, and directly "crossing" over.

Mountain bikes can reach speeds of up to 25 km/h on terrifying surfaces, and for humans who have been tormented by ruggedness for thousands of years, it is almost like laying a track on a mountain road. In fact, in the early days of the invention of the train, it was this same speed when passing over mountain roads, and now it is solved by the canopy of a paraglider.

The 25 km/h speed is achieved entirely under the auspices of a solar membrane canopy, so such a mountain bike is also a "strategic touring tool". The fundamental difference between it and powered paragliding is here, powered paragliding still needs energy, and solar energy cannot support their sustainable flight.

Yunnan, Guizhou, Guangxi, Fujian and other mountainous areas that were originally impassable by cars were all turned into thoroughfares with the help of the Round Table Knight mountain bike. Some of the villages that you often hear about mountain roads that take days to walk can now be reached in half a day.

This is a boon for the very poor villagers, because the powered paraglider is certainly much faster than this floor-mounted paraglider. Powered paragliders can reach speeds of up to 50 km/h and travel in a straight line, which is at least three times shorter than mountain roads, which is six times faster than mountain bikes.

Mountain biking takes more than half a day, and for powered paragliding, it's more than half an hour. However, powered paragliding is now 3 euros a year and mountain bikes are only 1 euro a year, which is a huge difference, for some poor mountain people.

An important point here is the shock absorption technology of mountain bikes, which makes the journey on rough mountain roads very smooth, and ordinary bicycles and cars may turn the pelvis of passengers even if they can walk.

With this powerful mountain vehicle, even the poorest villagers can borrow their neighbors' cars to carry their own chickens, dogs, and pigs to the market dozens of kilometers away to sell them at a good price, and also give them a taste for the people in the city. If you sell a pig, you can get a mountain bike yourself.

After having their own mountain bikes, the enthusiasm of the mountain people to develop the wasteland will be high, and they don't want the land that is ten kilometers away, but now it only takes half an hour to go to the field, and it is not difficult, and the land within a radius of dozens of kilometers has become fragrant and sweet
