An electric bicycle (e-bike, eBike, etc.) is a motorized bicycle with an integrated electric motor used to assist propulsion. Many kinds of e-bikes are available worldwide, but they generally fall into two broad categories: bikes that assist the rider's pedal-power (i.e. pedelecs) and bikes that add a throttle, integrating moped-style functionality. Both retain the ability to be pedaled by the rider and are therefore not electric motorcycles. http://www.isooyuelectricbike.com/electric-bicycle/

An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analysed. It was developed by Robert Bosch GmbH during the late 1960s under the supervision of Dr. Günter Bauman. The original sensing element is made with a thimble-shaped zirconia ceramic coated on both the exhaust and reference sides with a thin layer of platinum and comes in both heated and unheated forms. http://www.keditesensor.com/oxygen-sensor/

An air source heat pump (ASHP) is a type of heat pump that can absorb heat from outside a structure and release it inside using the same vapor-compression refrigeration process and much the same equipment as air conditioners but used in the opposite direction. Unlike an air conditioning unit, most ASHPs are reversible and are able to either warm or cool buildings and in some cases also provide domestic hot water. In a typical setting, an ASHP can gain 4 kWh thermal energy from 1 kWh electric energy. http://www.outesgroup.com/air-source-heat-pump/

Charcoal barbecue grills use either charcoal briquettes or natural lump charcoal as their fuel source. When burned, the charcoal will transform into embers radiating the heat necessary to cook food. There is contention among grilling enthusiasts on what type of charcoal is best for grilling. Users of charcoal briquettes emphasize the uniformity in size, burn rate, heat creation, and quality exemplified by briquettes. http://www.ouyalibbq.com/charcoal-barbecue-grill/

Recently, there are more and more signs that the ocean can no longer withstand continuous pollution, and we must protect the ocean. Ports, wharves, loading and unloading stations and ships that load and unload oil must prepare oil spill pollution emergency plans and be equipped with corresponding oil spill pollution emergency marine environmental protection equipment. http://www.sunruimarketing.com/marine-environmental-protection-equipment/

Gases in the mine can lead to asphyxiation and could also be ignited. Mining equipment can generate considerable noise, putting workers at risk for hearing loss. Cave-ins, rock falls, and exposure to excess heat are also known hazards. The current NIOSH Recommended Exposure Limit (REL) of noise is 85 dBA with a 3 dBA exchange rate and the MSHA Permissible Exposure Limit (PEL) is 90 dBA with a 5 dBA exchange rate as an 8-hour time-weighted average. http://www.zlocomotive.com/mining-equipment/

Baby travel gears can include a lot, such as strollers, baby carriers, baby walkers, baby child safety seats, etc. A stroller is a tool car designed for the convenience of infants in outdoor activities. There are various models. Generally, children from 1 to 2 years old play with a stroller, and children over 2 years old play with a toy car with wheels, a stroller. It will bring certain benefits to the child's intellectual development and increase the child's brain development. http://www.babygear.com.cn/baby-travel-gears/

The purchase of forklifts is very particular, and the purchase of high-quality and inexpensive forklifts can help companies greatly reduce costs. When purchasing a forklift, you should also pay attention to the purchase of forklift accessories, which will bring convenience to future repairs and maintenance. A forklift, the most commonly used parts are forklift tires. Reasonable use of forklift tires is also a cost-saving method. Forklift tires are generally divided into two categories, namely forklift pneumatic tires and forklift solid tires. http://www.blyshares.com/forklift-tires/

The current trend in the medical industry is minimally invasive surgery and minimally invasive plastic surgery. Many medical device parts that need to be used are produced by MIM technology. Minimally invasive MIM surgical parts have various geometric shapes and complex structures, which require very high dimensions and accuracy. At present, stainless steel, titanium and nickel-titanium alloys are widely used, and MIM technology is used for dental implants. http://www.chinamim.com/mim-medical-instrument/mim-surgical-parts/

Metal pails are larger capacity containers made of sheet metal. Its specifications include small open head pails, middle open head barrels, carrying barrels, special-shaped top barrels, full-opening conical steel barrels, full-opening barrels, straight-opening barrels, opening necked steel barrels, and so on. It has a very wide range of applications, involving many industries such as food, beverage, chemical, aerosol and other content packaging. http://www.gscustomize.com/metal-pails/
