When the police contacted the woman she presumed that the bike in question was the one which she reported stolen seven years ago.
"But when I read the letter further, I realized that it was my first three-speed bike that I got in middle school," Karina Murén told the local Gefle Dagblad daily.
Both tyres are punctured and the frame has been painted a different colour, but the frame number remained enabling police to trace the bike's rightful owner.
The bike was stolen some 20 years ago and the find has given Karina Murén hope that more of her missing two wheelers will show up.
"This was the first one that was stolen so it would at least be in the correct order," she joked.
Some 60,500 bicycle thefts were reported in Sweden in 2012, according to statistics from the Swedish National Council for Crime Prevention (Brottsförebyggande rådet – Brå). The figure represents a decrease of 8 percent from the previous year.
Bicycle theft however remains one of the most common property crimes and is particularly common during the summer months.
