Good for Newbie?

Hi! I’m looking to purchase a bike for myself so I can ride with my daughter once she learns how to ride. I live somewhat rurally in Maine, so I don’t usually find many good pre-owned options near me, but this bike is close by and I honestly really like the price.

I’ve messaged the seller to test ride it on Thursday, but I’m afraid it might be just a smidge too big for me. I’m 5’4” – the seller states the bike is size Medium. To note, I do currently own a 70s Austro Daimler Michelle mixte bike, but don’t enjoy riding it – mainly due to the gear shifters (I believe they’re called friction shifters).

What are your thoughts? I very recently purchased the 20” Cleary Owl for my daughter – the last photo shows her and the path we’ll be riding on until I feel like we can start biking around town together.
