I recently purchased a premium account and I have several junior riders in my inventory. I cannot find how to use them. I have checked the game guide but maybe not looking in the right place. Thank you for any help!

The Junior Rider items are used to hire them on the Hire a Rider page under Services :)

Thank you - I have found it and tried it but the rider does not appear as a junior rider. Is there any way to know which riders are junior?

Their art will be the same, but they will be age 15 :)

Junior riders are riders between the age of 15 and 21.

Thank you! My new rider is 15!
