Need suggestions for a way to lift a somewhat heavy prop

Greetings all,

Just starting to plan some new things for this year's haunt, and saw the 2017 motorcycle rider from Home Depot and wanted to make my own version. I picked up a kid's bicycle that looks kind of like a chopper and plan to modify it and add a skeleton rider. I would really like to rig up something to "lift" the front tire up (like he's going to pop a wheelie), but don't know what would be the best way. It doesn't have to be fast or violent (like a pop-up), just raise up a bit, and then go back down. I thinking probably something pneumatic (unless someone has another idea for me), but I have never worked with pneumatics and don't know the first thing about doing it. The hubby has an air compressor, so there's that...

They are pretty easy to work with. Never underestimate the value of springs to help reduce the load on an actuator, too. I made a skeleton sit up in a coffin last year with an actuator and used a simple Arduino to control a relay to reverse the voltage.
Did you use a spring for the forward/up motion to speed up the action? Then reverse would drive it down a bit slower while pulling the spring back?
