Although bike theft has always been a common issue, especially in urban areas, it increased during the pandemic in a number of cities. The pandemic led to an unprecedented boom in bikes sales. The rising demand, increase in ridership, and shortage of bikes nationwide among other factors, has likely contributed to a rise in theft, according to Bike Index, a nonprofit organization and national bicycle registry. Novice cyclists who picked up the habit recently or are relying more heavily on bikes for transportation may also be unaware of the basics of bike security — especially in urban areas.
