The man was stopped by traffic police in the town of Ortigueira, on the north-western coast of Spain on May 30th.
At around 6pm, the man was stopped and, when breathalyzed, was found to have an alcohol level of way over 0.25 miligrams per litre.
The alcohol limit for drivers in Spain is 0.5 miligrams per litre in their blood and 0.25 miligrams per litre in their breath.
When first breathalyzed, the cyclist had a blood alcohol level of 0.50 miligrams per litre, which rose to 0.65 when a second test was carried out 20 minutes later, according to Galician newspaper La Voz de Galicia.
He is one of the first to be fined so much under tougher traffic restrictions introduced in March 2015, which saw the penalty for drunk driving increased from €500 to €1000.
