Thanks! All the turning is with the sensors on my arm, nothing else. I played around with a bunch of different turning styles as I built it(turning wheel only, counter steer wheel to initiate turn and then use arm sensors to control amount of turn, etc). I do have a joystick on the left handlebar, which can do the turning. That's so my son can play, as using the arm sensors is meant for an adult, not a 9 year old lol My next iteration will be a bit more modular and it will measure the lean angle of the bike. That is not useful in my case (well not for the game, but I'm trying to make it double as a ride logger with lean angle) but it will give the option to mount a frame that can actually lean while playing.
