https://amzn.to/4xksI2B That's a basic kit that has a lot of what you would need. It's important to stay on top of maintenance at home, keep that chain lubed, make sure the brakes work well, things like that. On the road, you really only need stuff for emergency situations like a flat tire. Search for the YouTube channel "Park tool". They have lots of videos covering every facet of bike repair and maintenance. They are a fantastic resource. Not sure if you were looking for more than that, but that's my recommendation.
