Older version Go Pedal for smart 453. Purchased from a forum member a couple years ago. Works perfectly. No instructions and not BlueTooth model. Easy to install. Best to unbolt 2 10mm bolts on pedal assembly to easily access connector. Removed because I’ve sold my 2016 453. Payment by PayPal relatives & friends. $100 includes USPS small box priority mail. If interested please contact me by PM.
