GREENSBORO, N.C. -- A marketing research group, The NDP Group, found leisure bike sales jumped 121 percent in March compared to the same time last year. 

Commuter bike sales jumped 66 percent, childrens' bike sales increased 59 percent, and electronic bike sales surged 85 percent. 

"We are seeing sales. The typical day, one to two bikes, now we're seeing as many as 10 to 20 bikes sold in a day," said Woodie Anderson, manager at Cycles de ORO. 

The surge came as gyms were still closed and people were looking for new ways to get active.

"A few weeks ago I bought a bike. I was getting a little bit tired of running. I missed the gym, so I was looking for something else to do in quarantine other than my school work and running," said cyclist Austin Connors. 

Like Connors, many are turning to used bikes purchased on Facebook Markeplace or Craigslist, some people even digging up old bikes stored in their homes. Used bikes mean repairs, keeping shops busy.

"We're getting a lot of bikes that have probably been sitting for 10 to 20 years. That's a majority of what we're doing for repairs right now is getting these older bikes refurbished," Anderson said.

Bicycle shops have remained open throughout the closures because it is considered essential as a form of transportation. Many shops though are operating for sales and repairs by appointment only.
