Women have made history in the world of cycling in the U.S., with 60% of bicycle owners aged 18 to 27 being women. This marks a significant shift in an activity that has long been dominated by men. While many girls ride bikes during their early years, most stop by high school. However, this wasn’t always the case. In the 1890s, bicycles became a symbol of freedom for women, offering them independence and a sense of empowerment. Susan B. Anthony once said that bicycling had "done more to emancipate women than anything else in the world." By the end of the 20th century, the number of teenage girls cycling dropped significantly. Research from the National Children's Bureau showed that boys cycled about 138 miles a year, while girls only averaged 24 miles. This decline was largely due to fashion or fear. More recently, data from major bike-share programs in New York, Chicago, and Boston revealed that for every three men riding, only one woman did. Nationally, women accounted for 24% of bike trips in 2009, but the numbers are higher in countries like Germany (49%) and the Netherlands (55%). Interestingly, women aged 18–24 actually ride more days per year than men of the same age, but their riding frequency drops sharply after they start raising children. However, female baby boomers (aged 45–64) ride almost as often as their male counterparts, and older women continue to cycle frequently. In the early 2000s, cycling shifted from a hobby to a sport, but now it’s becoming more of a daily transportation tool. The number of women who commute by bike has grown by 58.8% since 2006, outpacing men’s growth. Between 2011 and 2012, women’s bike commuting increased by 10.9%, compared to 8.4% for men. To attract more female riders, bike brands have introduced designs tailored for women—like smaller frames, brighter colors, and comfortable saddles. These efforts have led to over 1.3 million women riding 110 days or more annually, up 8% since 2005. Despite these improvements, safety remains a top concern for women. A 2010 survey found that 73% of women cited distracted driving as their main issue. Other concerns include harassment, the difficulty of carrying children, and the risk of injury. Fortunately, new developments like cargo e-bikes and improved bike lanes are helping address these challenges. Insurance options like Velosurance offer coverage for theft, damage, liability, and even medical expenses, giving cyclists peace of mind. With growing interest and better infrastructure, the future of cycling looks brighter—and more inclusive—for women.

Optical Fiber 1-color Pyrometer

This classification includes one color infrared pyrometers which consist of lens, fiber optics and processing components. Fiber optic can bear high temperature up to 250℃ and do not need additional cooling. It has strong casing, use stainless steel lens(with air purge functions), die cast aluminum housing, protection grade is IP54. One color pyrometer determine the object temperature by receiving the sum of the narrow-band radiation energy, around(0.85~1.1)μm, emitted by the object. product detector nornally use si. Pyrometers can be widely used in metallurgical industry (wire rod, hot rolled plate,forging) and forging industry, heat treatment, induction heating, monocrystalline silicon and polycrystalline silicon,etc. SMART-F series is not only suitable for general industrial occasions of temperature measurement, but also suitable for installation in occasions with strong electromagnetic interference and high environmental temperature.
