Looking to buy a new bike? You’re in good company. The pandemic triggered a home-fitness boom, leading to increased demand for bicycles. But the pandemic also disrupted production and transit networks — most bikes are produced overseas — and many bicycle shops are still bare of new inventory or limited to a few models in odd frame sizes. That doesn’t mean you won’t be able to buy a new bike in time for some summer fun. But it does mean that you’ll have to scour retailer inventories carefully and may not be able to buy the precise brand or model you want. Be prepared to wait for several weeks before your new bike is in stock and ready for delivery, too. If that doesn’t discourage you from buying a new bike (and it shouldn’t), start your search at one of the following online bike sellers.
