Game Cabinet controlled by Handlebar (with brakes) and a StepMaster

I sincerely hope this post is understandable. If not, I'll gladly add more info as required.

Me and a team of students are hoping to make a set of game controls using a StepMaster ( as an example) , where we hook up a gyroscope to the paddles (taking steps to move forward), and add buttons or bike brakes to the handlebar, squeezing them to control movement and attacks on a screen. What sort of Genuino (as we're in the EU) items would we need to purchase to make something feasible with that sort of setup?
