Thanks for the tips so far!
Bottle/pack decision wasn't one I was worried about just yet, but I like the ease of use the pack would undoubtedly provide.
Shoes and a better helmet are the next necessities on my list. Got some inexpensive pedals at the shop, and will upgrade those once I tear them up.
Really excited to get healthy enough to ride it soon-ish. Side note, any Spinal Surgeon Cats? Lol
