It is estimated that the time of loosening soil sowing will start later than in previous years, and of course there is no idle during this period, but at home thinking about doing things, as for doing bicycles.

The roads on the island have been almost built, especially the most troublesome road around the island is almost complete, and it is time to make a bicycle!

It took three or four months to build the road, and if the bicycle that I had been thinking about was not put into use for a long time, it would be a bit of a shame to live up to the hard work of these months.

In fact, it can be produced very early, but it has been busy last year, and the schedule is full, so I can only postpone some things of less importance.

Although construction has only started until now, it is not too late, especially since the preparation of materials is progressing one after another, and the preparation time before production is almost negligible, and if nothing else, it will be made quickly.

Not only is the wood ready-made, but there are also nearly 10 planks, which can be turned into bicycle parts with simple modifications.

Bicycles look complicated, especially many modern bicycles are extremely exquisite, in fact, in essence, they are similar to unicycles, and the most primitive bicycle structure is not difficult.

The wheels can be directly applied to the unicycle method, but the size will be quite different, the steering and other more demanding but more delicate parts can be made of iron, and if the iron cannot achieve the effect, there will be gold and silver.

I have full confidence in whether I can make the bicycle, a few years ago it was to catch ducks on the shelf, and there was no condition to create conditions to make the tools needed, but now it is different, basically after having certain conditions, it will start.

Just like the previous unicycle, since you want to do it, you will definitely succeed, the only thing I don't have confidence in is that I am afraid that it will be too laborious to use and unbearable!

After all, the weight of a wooden bicycle is much heavier than that of a metal bike with modern technology, and the most troublesome transmission is quite difficult.

The result of one increase or one decrease is an increase in difficulty, so there is still a lot of uncertainty about what will happen in the end.

......

Although the future is uncertain, my passion for it is undiminished, and the reality is so cruel that it may be the only vehicle I can hope to make, and there is no other choice.

Many times to do a thing is not afraid of failure, the most afraid is the fear of failure and retreat, as long as you bravely take the first step, you can have a second step, the third step, through continuous improvement and perfection can always achieve the goal.

If you are afraid of failure at the beginning and stagnate, although there is no failure, you will also lose the opportunity to succeed!

Of course, everything has to be considered in terms of my own strength, and my ability makes me feel like I can make a bike, so I was ready to do it, and I wouldn't have started if I didn't have confidence.

The wheels of both bicycles are made of wood, and at the end of the lap they resemble the wheels of a unicycle, with a ring of rubber shock absorbers five centimeters thick.

Rubber is an indispensable step, and it is found that it is too effective on a wheelbarrow, and if the wheels are spliced with pure wood, not only will they jump up on the road, but it will not take long for the whole structure to be shaken and loosened.

There is a thick layer of rubber shock absorption, and the effect is naturally not to be said.

The diameter of the wheels is larger than that of a wheelbarrow, and the width has not dropped much, reaching five or six centimeters, which looks particularly strong!

The frame is relatively simple, but the difficulty is mainly in the process of splicing, which requires various sizes and shapes of wood to be connected together tightly.

This is a very big problem, and each piece of wood has to be modified many times to complete the splicing, but fortunately it is all done.

Pure wood structure can make a complete frame, but it is not possible to make all kinds of precision parts, but after the frame is completed, the difficulty of the accessories is less, and it can be carried out according to the size.

It's nice for me to be able to collect some iron on the beach, and I wouldn't want to waste it on my bike without that.

......

A pure wood structure can also be successful, but it will increase the weight of at least ten catties compared to the combination of metal and wood.

Ten pounds is a great reduction for a bicycle, and the total weight of an ordinary bicycle is only twenty or thirty pounds, almost a third of the reduction.

In addition, the parts made of metal will be stronger and more effective, such as the spring under the seat cushion, although the texture is hard, but the vibration is several times less than when it is not installed.

In fact, the completion of the whole project only took ten days, or in the process of starting from scratch encountered many problems, slowly groping and delaying a lot of time, otherwise it will be shorter!

Compared with other projects, it is relatively relaxed, especially after ten days, I hardly feel tired, and some are only happy when I am getting closer and closer to success.

After ten days of repeated tossing, finally at this moment, a complete form of bicycle appeared in front of my eyes.

It has an average height of about one meter and a length of more than one and a half meters, and if it weren't for the limitations of the material, I would have liked to make it smaller, because it is a light means of transportation.

Reducing the size appropriately will naturally make the weight lighter and more sensitive, and the force used will increase exponentially for each additional kilogram of travel.

But alas, for one reason or another, this is the limit I can reach for the time being, and it would be better if I had to make a new one at this time, it would be lighter, but it wasn't necessary!

It doesn't seem to be useful to say so much, but in the end, you have to test it to prove whether it can be used, and only if it can be used, the next stage is to improve it to become useful.

Because of the material and process, the transmission device does not use the chain, even if I want to make it, the structure of the simplest gear is selected, relatively speaking, it is more difficult to use, and some of the force will be offset by the gear.

......

Next, I sat on it to test whether it would fall apart, of course, more than a hundred pounds can't bear it, then it can't be described as a failure, it's completely rubbish!

The problem of brain repair did not arise, but the first feeling was that the seat cushion sewn by multi-layer crocodile leather was not bad, and the bottom added a lot of waste fabric and multi-layer crocodile leather, as well as a few springs The shock absorption effect is obvious, which is not much better than the seat cushion of a professional bicycle.

The left and right steering of the front of the car is still a bit heavy and needs to be improved slightly, and the feeling of pedaling up is not very good, except that it is heavy and difficult.

After almost a little more than a meter of progress, it stopped, and the sound of "creaking" could be heard, which was very sharp and disgusting......

It's impossible to give up at this point, and it doesn't seem too difficult to improve.

The first is to disassemble the problematic parts and repair them to make them smoother, so that the contact surface between the gears is slightly smaller, and the area of friction is reduced.

A small number of problematic parts have also been reshaped or replaced, and even the rubber part on the outer edge of the tire has been cut half a centimeter on each side to reduce the ground contact area.

The result of the re-test was much better than the first test, and I stepped up and walked forward more than three meters, and the sharp sound dropped by about half.

However, the position of the sound can no longer be changed, it has reached its best state at present, and this is when I think of not re-modifying, but lubricating oil.

Lubricating oil is an important part of various machinery and vehicles, without oil lubrication, machinery is always difficult to achieve the best state.

Not only does it reduce sound and friction, it increases the life of the component, it also significantly improves the effect of the force.

When I applied some peanut oil to a few gears and moving parts and tested it again, I was stunned by the results, and I kicked out the car for more than five meters!

You know, it's at least half as efficient as a modern bike, and there's no need to expect it to be fully capable, and I'm very happy with it.

......

A simple experiment doesn't mean it's successful, and there are many attributes and problems that need to be discovered.

The next step is to test other abilities, such as how fast you can drive on the road, how far you can drive, how tired you can get from running a few kilometers, and so on.

For the first means of transportation is always like a chicken blood, where to find its problems, has been enjoying the joy of riding!

As a result, I went around the island and didn't find any problems, and when I got home, I was very excited, and I even had the urge to run another lap.

Of course, it is absolutely surprising that I can run a lap without any problems, which shows that the structural strength of the bicycle is quite good, and there is no casual walk for a while and the chain will be dropped.

And its speed and other properties are also almost in my hands during this trip, and the speed can reach about 10 kilometers per hour, or 15 kilometers on the main road.

It's a far cry from a modern bicycle that can travel at twenty or thirty kilometers per hour, but it's very commendable here.

Ten kilometers of road, which is not even flat, is quite a good result, and it is at least seven or eight kilometers around the island from the house, and it is close to an hour of driving, and it is not yet exhausting.

An hour's bike ride is about the same as digging for an hour, but I'd definitely go for a bike because it's a pleasure to drive.

Overall, I'm happy with the bike, it's more than I expected in terms of performance and effort, and it's amazing to be able to do it now!

Except for a small problem after going around the island, basically all the parts are still in good condition, and the scene of falling apart did not happen at first.

The better days are coming, and it will be much faster and easier to get around the island in the future, and more importantly, I fell in love with the feeling of cycling, enjoying the breeze and freedom!

So in the following days, cycling around the island became almost a daily activity, every two or three days, and even the occasional trip to the beach to pick up garbage would be ridden on a bicycle, which shows how much I love it.
