Cycling wear

Summer sun hat, flat mirror, rain, wind, rain hat can file, rain splash than the eyes. Anti flies mainly flat mirror, wearing a leather hat in winter sunlight, knee, waist shoes, airtight sweatpants, retaining the. Leather hat: the winter wind, cold wind and direct the forehead, particularly low temperatures, over 0.5 hours, resulting in headaches, not the spirit of the day. If the 3-wheel trike ride headache had better pay attention. You can wind, then wear a hat down jacket, no problem retaining the forehead: only wear gloves, easy to frostbite, take care of the post, and then wear a single glove basically it. Knee: winter wearing knee is not too useful, after wearing knee pads, wear an air-tight pants. Air-tight pants to wear, otherwise his legs over 0.5 hours, basically numb. Waist Shoes: The main nursing ankle bone if worn loose, over time, fall easy leg pain. Drinking water, brown sugar, ginger can ease leg pain.

Electric car battery service life

The battery is a chemical substance, which is a certain service life, such as dry cell (including ordinary alkaline batteries) can not be charged like a battery, the service life of course, only once. For rechargeable batteries, generally we charge cycles to measure the length of their service life. Nickel-cadmium battery cycle life of about 300 to 700, the number of nickel-metal hydride rechargeable batteries typically 400 to 1000 times, lithium-ion battery is 500 to 800 times. The service life of the rechargeable battery is not only affected by raw materials, production processes and other factors used in the production of 3-wheel trike batteries, but also with the battery charge and discharge method and the actual usage closely. For example, someone started using in 1985, section 6 HITACHI nickel-cadmium batteries, has continued to use, but some of the battery capacity reduces. It seems that as long as the use is reasonable, rechargeable batteries can be achieved even more dramatically than the nominal service life.
