A bicycle trailer is a motorless wheeled frame with a hitch system for transporting cargo by bicycle. It can greatly increase a bike's cargo capacity, allowing point-to-point haulage of objects up to 4 cubic yards (3 cubic metres) in volume that weigh as much as half a ton.
Different types of trailer are designed for various purposes, cargo requirements and riding conditions: Bike Cargo Trailer, Bicycle Cargo Trailer, Motorcycle Cargo Trailer Hangzhou Datasports Equipment Co.,Ltd(Oembicycle) , https://www.oembicycle.com
Our general method of distinguishing car seats is to distinguish them by the materials used. Basically, they are divided into two major categories. One is a fabric seat; the other is a leather seat.
What is a fabric seat?
The fabric seat is a seat made of chemical fiber material as the main material. Fabric seat is the most cost-effective, although not significant, but it is practical. Its advantages:
1. It is not easy to damage, has a long life, and it is difficult to repair, but it is not easy to age.
2. The velvet seat has a stronger friction and it feels more stable when seated, and it does not feel slippery.
3. Manufacturing costs, good air permeability. Its disadvantages:
1. Dirty and difficult to clean. Dirty things fall into the seat and it's very troublesome to clean.
2. The heat dissipation is not good. Due to the relatively high heat absorption of fabric seats, we will feel very uncomfortable and have a “stupid†feeling when we sit down and open the door in the summer.
What is a leather seat?
The leather seat is a seat made of natural animal skin or chemically synthetic leather. Manufacturers will use leather seats to improve the interior trim of the vehicle. Its advantages:
1. Easy to clean. Relative to the flannel seat, the dust can only fall on the surface of the leather seat, and does not penetrate deeper into the seat. Therefore, the cloth can be wiped gently to complete the cleaning work.
2. easier to heat. Although the dermis also absorbs heat, its thermal performance is better. At noon in summer, the sun-burning vehicle can take a few shots to dispel heat, or sit up for a while and it won't feel so hot. Its disadvantages:
1. The surface is vulnerable. Sharp hard objects such as knives, scissors, and needles leave marks on the leather and are prone to aging.
2. The feeling of sitting is more slippery. Due to the characteristics of the leather seat material, it makes us feel very slippery and the friction is relatively small.
3. May burn. In summer, when the surface of the leather seat is exposed to the sun, the surface temperature can be very high, reaching about 60 degrees, and it may cause skin burns.
4. It is not airtight. It took a long time to sit on the leather seat in the summer. The legs are sweaty. This is the drawback of the leather chair and it is also the source of the ventilation seat's birth.
Leather seats ≠leather seats When many manufacturers have promoted their own cars have "dermis" seats, it seems that between the instant leather seats from the high-end configuration suddenly become any level of any price car can be assembled standard configuration . But is the leather seat in your car the "dermis"? the answer is negative.
Most manufacturers use artificial leather, or some manufacturers will use semi-dermis semi-artificial leather and regenerated leather on the seat (the skin dregs, skin fibers are ground, bonded by high pressure with an adhesive to form a sheet, with a certain leather characteristic). For seats made of non-animal skin we can call them leather seats, so we must pay special attention when shopping.
How to judge the quality of the seat cortex, we understand that we can judge from the following aspects.
At first glance, the Phi skin is smooth and delicate. Second touch, good skin feel soft, smooth and elastic, if the leather surface particles, plate hard or sticky, then the quality will not be good. If you have the chance to get a sample of skin, there is some char after lighting it, and there is no leather. Four rub, wipe back and forth with a damp cloth on the surface of the leather, if there is bleaching, then the quality is not off. Five pull, two hand pull the leather to pull both sides, if there is a seam or exposed white background, then the poor quality of leather.
First, use and maintenance of seats.
Because fabric seats have relatively large fiber holes, it is best not to eat or carry debris in the car. If it is necessary to do so, be sure to pay attention to it. Do not let the fine residue or impurities of the food fall on the seat. In order to avoid tainting maggots or other microorganisms and causing strange odors and thus affect your health.
Although fabric seats are easily soiled, fabric seats are relatively simple to clean. When it is not very dirty, use a brush and a vacuum cleaner to clean it. While brushing the surface of the seat, use a vacuum cleaner to suck it out.
For particularly dirty seats, first use a brush to clean the dirty area when cleaning, then use a clean cloth dipped in a neutral detergent, fully wipe the seat surface in semi-dry and semi-wet condition, and finally use a vacuum cleaner or dry cloth. Clean the seat and eliminate excess moisture.
Let's talk about the use and maintenance of leather seats.
1, car leather chair as far as possible away from the heat source, such as too close to the heat source will lead to dry leather. 2, do not expose to sunlight exposure for a long time, so as to avoid leather fade. 3, regular implementation of cleaning and maintenance, a week using a vacuum cleaner to remove dust. 4. Do not use a hair dryer to quickly dry the leather during cleaning. Do it naturally. 5. Clean up the dirt that spilled on the seat in time to avoid chemical corrosion on the seat. 6, to avoid scratching the sharp objects In terms of maintenance, leather seat cleaning we use special detergents, do not use household detergent, detergent and other non-specific leather cleaners, because the general non-leather special emulsion and grease molecules Larger particles can not penetrate into the leather tissue to form a protection, but instead block the pores of the leather and lose the breathability of the leather, thereby accelerating the formation of leather hardening and cracks.
In addition, it is best not to use a damp cloth when cleaning, because the moisture can penetrate into the sponge in the seat, so that the seat is not easy to dry, and the wet leather is also easy to re-adsorb dust. If a damp cloth is used, it is best to use a vacuum cleaner to clean the seat so that it will dry quickly. It is worth noting that once leather seats have become fouled, they must be cleaned in time. If they are not cleaned after a certain period of time, these stains will be difficult to remove.
In addition, the surface of the leather that is in constant contact with the human body, due to friction and more oil, looks more shiny, do not think it is very clean. On the contrary, the glossy leather seats indicate that the pores of the leather have been severely clogged, which is a precursor to the beginning of leather damage. If the leather is not immediately cleaned, the normal life of the leather will be greatly reduced.
Ventilation seats, electrically heated seats Precautions for use Nowadays, many cars are equipped with heating and ventilation functions for the seats so that your back and ass can be in intimate contact with the seats in both winter and summer.
What is the seat ventilation feature?
The seat ventilation function uses a fan to inject air into the seat, and air flows out from the small holes in the seat surface to achieve the ventilation function. When a passenger sits in a seat, the back of the body is in close contact with the seat surface, and the air in the contact portion does not circulate, which is not conducive to the elimination of sweat, and may cause the body to feel uncomfortable. The ventilation function effectively improves the air circulation environment where the human body is in contact with the seat surface. Even if it is taken for a long time, the contact surface between the body and the seat will be dry and comfortable.
What is the seat heating function?
The seat heating function uses the electric heating wire in the seat to heat the inside of the seat and transfers the heat to the occupant through heat transfer, so as to improve the uncomfortable seating of the seat caused by the coldness of the seat after long-term parking in winter. sense.
Whether it is ventilation or heating function, it is ultimately achieved through electrical EQUIPMENT. Therefore, during the process of use, special attention should be paid not to spilling water, causing damage to electrical components or other problems.
Finally, here I would like to express my personal opinion of seat purchase. If you have enough money, then you should choose leather seats. However, if you don’t have enough money at hand, it is better to choose fabric seats because fabrics are better. Seats are more cost-effective and relatively easy to manage. Moreover, good fabric seats are definitely better than low-end leather seats. Ventilation and heating functions depend on your personal preferences.
By number of wheels:
Single-wheel: a single rear-mounted wheel. Though of limited towing capacity, this design tends to be more stable (when moving) than trailers with two or more wheels. The single wheel can tilt from side to side when cornering (as the bicycle itself does,) allowing for coordinated turns at relatively high speed. The connection to the bicycle is simpler than a two-wheeled trailer since only two degrees of freedom are required- the trailer tilts with the towing bicycle.
Two-wheel: A two-wheel design makes possible much greater load carrying capacity and a wider cargo bed. Though not suitable for high speed, they are ideal for everyday cycling (very much like towing a trailer behind a car). Two-wheel trailers tend to be as wide or wider than the handlebars of the bicycle, therefore care needs to be taken when riding through narrow spaces.
