Cyclists are demanding safety improvements at a busy junction which they say is putting riders' lives at risk.
About a year ago, Leicester City Council installed contra-flow cycle lanes in Granby Street, but cyclists say they have created an unintended danger at its junction with Northampton Street.
The Leicester Cycling Campaign Group (LCCG) said motorists turning right out of Northampton Street on to the one-way Granby Street often do not expect riders to be coming the other way on the green cycle path.
LCCG spokesman Eric Ludlow said there had been a string of near misses between startled riders and drivers because of the confusing set-up and he feared a cyclist could die if it is not altered.
He said: "The contra-flow cycle lane is an excellent idea, but there is a desperate need to make changes where it crosses Northampton Street.
"Motorists are simply not expecting to see anyone approaching from their right, as they know Granby Street is one-way for motorised traffic.
"At the same time, cyclists think they are safe as they are riding in a designated cycle lane. It's an accident waiting to happen.
"We warned the council about the dangers when the cycle lane opened, but nothing has been done. I just hope it doesn't take the death of a cyclist to make change come about.
"Drivers often cruise out of that junction without stopping. If a stop sign was put up for cars exiting Northampton Street it would be much safer.
"The junction could also be altered to make the turn more 90 degrees, stopping the cars rolling out without looking."
Liam Dunphy, managing director of the Ebike Electric Cycle Centre, on the junction, said: "Since we opened, four months ago, I don't think a day has gone by without seeing a near-miss.
"Cars barely seem to slow down. The junction needs to be redesigned to force them to do so, otherwise someone is going to be killed.
"I have to say, cyclists do not help themselves sometimes because they come hurtling down the street. They think they have a clear run on a cycle lane but they are going too fast."
A city council spokesman said there have been no accidents at the junction involving cyclists in the past five years, though it was aware of concerns. He said: "We are aware of concerns about the safety of cyclists at this junction. Improved signage was installed about 12 months ago to remind motorists of their responsibility to give way.
"We are also looking at extra options to reduce speed and road danger for people travelling by foot, bicycle or car, while maintaining essential access for large vehicles."
