Teenagers in Potters Bar can take part in free BMX sessions tomorrow.
Hertsmere Leisure will hold the activity at Parkfield Open Space, off High Street, from 11am-2pm.
Helmets will be provided at the session which will be run by bike expert Mike Tearle.
Young people will also have the opportunity to try riding a uni-cycle and a bike which turns right when you turn the steering wheel left, challenging coordination and reflexes.
The initiative has been funded by Hertsmere Borough Council.
