As China regains its historic bike-friendly reputation with the bike-sharing app boom, a recent report stated that the distance ridden on shared bikes in China has surpassed 2.5 billion kilometers, which is equal to 3,300 round-trip journeys from Earth to the moon.

The report, compiled by bike-sharing giant Mobike and Beijing Tsinghua University Institute of Planning and Design, pointed out that the multi-billion-kilometer milestone also means the avoidance of 170,000 car trips' worth of carbon emissions, which would have churned out 4.5 billion micrograms of PM2.5.

As bike use continues to grow, cities can also save space on parking, the report noted. In Beijing, the parking spaces saved could potentially be as large as five National Stadiums. In Shanghai, that figure could equal 15 People’s Parks.

Bike trips have doubled since 2015. Some 11.6 percent of trips in cities that offer bike-sharing services were made by bike, while 26.6 percent were made by car. However, before the popularization of bike-sharing apps, those figures were 5.5 and 29.8 percent respectively.

Bigger cities have also demonstrated different characteristics when it comes to shared-bike use, according to the report. Specifically, Beijing is the “earliest city,” with residents flocking to use the bikes during the early-morning rush hour, while Shenzhen is the “city of night,” as nighttime bike rides there outnumber those in other cities.
