Buying first used mtb need help

Don’t do it. Geometry is all wrong for a hardtail. Talk to some guys/gals who ride where you will be riding g and see what they are using

I would pass on this one. The saddle looks like it’s seen better days and would definitely need replacement. Tires are cooked. If you planned to ride some dirt trails, the tires would let you down. The groupset isn’t in the worst condition ever, but without a chain checker, it’s tough to tell the actual condition of the drivetrain. Brakes, especially the rotors, are looking okay, visually, and there is no obvious residue. But again, it’s tough to tell. There’s probably something better for you.

If you can find something in your price range, follow this:
1. Thru Axle, not QR – This way, you can upgrade your bike over time and not be limited by the frame design
2. 1x Drive Train – 3x is great, just not for trails your chain will come off
3. Any name brand brakes Tektro, Shimano, etc. dont screw around with poor quality brakes, they will let you down

If that’s all your budget will allow. I would go ahead and offer $300. Most likely, you’re going to need to change out the saddle, the stem/bar setup. Definitely take her for a test spin. Make sure the wheels are true and tires hold air.

I started MTB riding 3 decades ago on a fully rigid Fuji.

What do they say about geometry and bikes… every 6 years The tech outdates. If that’s still the case, IDK.
Ride what you got !!
