Police are launching a crackdown in a bid to tackle bike crime - and to help cyclists get their stolen property back if it is swiped.
Of the 349 stolen bikes, which were recovered between July 2012 and July, this year, in the Hillhead, Partick and Anderston areas, only eight of the owners could be detected.
It is estimated that the stolen property was worth around £250,000.
Inspector Gillian Docherty, of Glasgow West End Police Office, said bike crime was a major issue because of the amount of students in the area.
She said: "We do have the university here which brings a lot of students in and many of them cycle.
"We have stolen bikes varying in value from £500 to £3000. And the review that was carried out of the 349 bikes stolen last year showed that this amounted to a figure in the region of £250,000.
"People can sometimes think it's a minor crime but there's a lot of money involved."
To tackle the issue, Glasgow police are urging cyclists to security mark their bike free of charge.
A team of officers will be based in Glasgow's Kelvingrove Park skate park tommorrow from 10am-3pm with more than 1000 marking kits.
Residents can get their bike permanently 'tattooed' with a security number and then register their details online.
The scheme, which is used by Metropolitan Police, has been funded by the Hillhead, Partick and Anderston Area Partnership.
Ms Docherty said they hoped to launch further workshops - and if it works it may be rolled out across the city.
She said: "We're aiming to mark as many bikes as possible.
"It makes a difference because we do recover a lot of bikes but there's no way of knowing if they are stolen.
"Thieves can target tenement closes, back courts, gardens or they can steal bikes from the street.
"So we'll be giving out advice on the best way to lock your bike up securely."
The drive is supported by the Scottish Green Party in Glasgow, including Hillhead councillor Martha Wardrop, who raised the issue after students in her ward kept experiencing bike theft.
She said: "We have had a problem with bike theft and we need to make sure it is a hostile environment for people who steal bikes."
Her Green Party colleague, Councillor Nina Baker, of the Anderston ward, said: "We want more people to cycle but the marking will only help a bit - owners must take lots of care.
"Many posh bikes are worth more than many cars."
