Thousands of people traveled by bicycle through Slovenia's capital, Ljubljana, on Friday to protest the government.
They accused Prime Minister Janez Jansa of using the coronavirus pandemic as a pretext to restrict liberties.
They claimed that Jansa is trying to increase police powers, inciting hatred against migrants and making personal attacks on journalists.
Slovenia applied a rigid blockade in response to Covid-19 in mid-March, but facilitated some measures two weeks ago.
To date, the country has confirmed 1,450 cases of the disease and 100 deaths.
BBC's Guy De Launey says that Ljubljana is a cycling town, so protesting on two wheels made perfect sense and also allowed participants to observe measures of social distance.
Most of the time, it was a calm and good-natured affair, adds our correspondent. But the pilots chanted slogans against the prime minister, including "thieves" and "under the government".
Environmental organizations joined the protest. They said the government had inserted clauses in the emergency legislation that would prevent NGOs from consulting on construction projects.
The government denied any wrongdoing.
