This has been an idea of mine for a while. A Peloton bike but instead of paying $50 a month to get yelled at why not spend $0 a month to yell at people! Imagine Mario kart but in order to accelerate you need to pedal a bike. I swear this has been done before but for games that aren't fun. Mario Kart is inherently fun so adding the pedaling controls to doesn't damper the experience. In fact I have had people tell me that they wish this was in gyms. From my experience I can tell you I will never use the gym's boring bike when I can do this in my own apartment. They way it works is really simple: the program detects how your leg-strap Joy-Con is moving. Considering that your legs always move in the same patter on the bike the program uses the Joy-con's data to determine when to press the "A" button to accelerate. The RPM you do doesn't affect the speed but if you want a harder exercise increase the resistance on your bike!
How to Set-up!
Let's go over how to sweat bullets while dodging bullet bills. This should be too hard as this is just a script to upload to the Cronus Zen. Make sure to read the Ring Fit Round Up page if you aren't familiar with the software/hardware. Also remember one huge thing: SWAP the location of your Joy-cons for these Ring Fit Mods. The Ring-Con Joy-Con is now in your Leg Strap. The Leg Strap Joy-Con is now in your Left Hand.
Head over to my Cronus Zen GitHub Repository and download the MarioKart_Bike.gpc file! You'll need to upload the .gpc file to your Cronus Zen before using it on the Switch. Below is a quick rundown on how to set-up your Cronus Zen with the assumption you've read/watched the tutorial! If you need help DM me on Twitter or visit Cronus Zen's Manual for an in-depth tutorial!
Ehhh for now, No. This works just fine and maybe I could add something that detects the RPM but I'm lazy. This is just a template script and most likely can be easily edited to work for other games! With some quick edits I was able to make this work on Final Fantasy XIV and rode around Eorzea for a quick workout on some days.
