I shot this "freestlye" meaning I didnt ask the bike riders where they would be or what they were going to do. I just tried to shoot. Had to keep an eye out for other people in the park too. I need to be much closer.
Im in the process of getting a new mount to haul something bigger around. The GoPro has its limits

Shot in 1080 at 30fps. From now on I will be shoting 2.7K at 30fps with Protune on and raw mode

Please, tell me how to improve if you can. Im not very happy with Image quality. But, it was very windy and this is my cheap gimbal

Looks good! Have you tried using the Warp Stabiliser effect in After Effects? It does an excellent job of eliminating camera shake. It does come at the expense of image quality but I find it to be acceptable, especially if you shoot at 2.7k and edit at 1080p.

I also find that shooting at 1080 60p and slowing the footage down by 50% makes it look a lot smoother.
