I have a car and a pitbike, but my car is not much intended for fast riding, I use it more to go shopping or to work, and the pitbike is more for the soul and speed, I really like to let this beast out at the weekend and gain speed somewhere on an empty road, Adrenaline is unreal, I capture speed with one app on my phone, but it only works on the iphone,
https://speedometerfree.com/ very helpful for me to watch my speed, by the way it works not only with the pitbike, but also with cars, boats, and while running I think those who do fitness it will be very helpful.
