Cyclists are being told to slow down as calls grow for Police to have tougher powers to stop speeding riders.

Some riders are being clocked st travelling sat 20km per hour on shared paths, which have a speed limit of 10km per hour.

Police can currently fine cyclists for speeding, but not on the spot.

For riders to be fined, it needs to be done via summons, which can take a lot of time to issue.

Ben Rossiter from Victoria Walks told 7News “We think it’s a gap in our road rules that (cyclists) should be able to be issued an infringement directly. We know walkers and cyclists don’t mix, particularly fast-moving commuters cyclists, and older walkers, people with disabilities and vision impairments.’’

A council survey found more than 10,000 people ride into the city each day – the equivalent of 52 full trams.
