Just Got My First BMX — How Can I Make It Better?

Hey everyone,
I’m super excited — I just got my new BMX! It’s my first one, and I’m already loving the feel of it.
I’m here to learn from the pros and long-time riders in this community. What are some simple upgrades, tweaks, or maintenance tips I can do to make my bike perform better and last longer?

I’m open to advice on:

Parts to upgrade first

Must-have accessories

Beginner-friendly tricks or skills to learn

Maintenance routines you swear by

Thanks in advance for the tips — and I’m happy to share pics if you all want to see my ride!
