As far as mountain bikes go, at the bottom of the barrel of new offerings that you can buy that probably won't kill you is the Walmart/Ozark Trail hardtail: https://www.walmart.com/ip/Ozark-Trail-29-Ridge-Mountain-Bike-Medium-Frame-Gray-Adult-Unisex/1656914661?athbdg=L1600

You will likely need to know how to/pay someone to give it a once over to make sure it wasn't set up incorrectly and your bars won't fall off mid-ride or something.

So after talking with some co-workers I decided I was just going to keep what I have for now and ride it until it breaks... not gonna put a dime in to it, but try to tighten things up and ride it till the wheels fall off. Planned to start saving some money and looking for a more quality bike while I see if I continue to ride this one. So I get home and my tires were a little low so I filled them up to 50 PSI. Two minutes down the road and the front tire pops. Luckily its supposed to downpour the next few days as I decide what Im going to do.

If you're in or near Philly take whatever bike you end up with to a co-op like someone mentioned above. They typically will help you fix your bike, providing tools, space, and help as needed.

You'll end up with a more functional bike and learn how to fix and maintain it at the same time.

Be pretty decent? Just trying to gauge what to look for. Yesterday I was gonna pick up a 100 dollar bike on amazon now you guys got me looking at 500 dollar bikes. In reality a department store bike will probably fit my needs completely, but I 100% agree with what everyone has said in here. If anything.. I'll drop 500 bucks on a bike it will definitely motivate me to use it. I do have lots of bike trails in various parks near me, nothing like the videos posted in here, but I could go on them.

https://philadelphia.craigslist.org/bik/d/philadelphia-vita-elite-large/7728886706.html

The 1st one would be great provided everything works _and_ it's your size. Do you have a short torso? If so, it might fit ok. Or it might feel really cramped.
The seat is really high in the picture, but possibly about where you'd need it.

This is what you're looking for, something with medium sized smoother tires, no suspension fork, 700C wheel size.
Ideally 9 speeds for better availability of cheaper quality replacement parts. 7 speed to be avoided cuz that uses a different tier of older generation parts that, sure, you can get replacments for, but it's never gonna be particularly well built, so you're still throwing more money away.

Hard pass on the rim brakes and freewheel (14–34, seven‐speed) at that price.


GT Aggressor is a classic of cheap bikes.

Dick’s has the eight‐speed cassette model for less. I’m not seeing a downside to that other than the wheel size, but that’s not worth two hundred dollars. I don’t know how much they charge for shipping though.

I have 26" now and that is fine for me so 27.5 would probably be ideal. Whats the deal with the lack of kickstands? I get at a higher level shaving weight and everything, but down at the lower level, don't most people need to eventually rest their bike somewhere?

Went out today to go look around. Went to Dicks to look at that GT Aggressor which is completely out of stock everywhere. Moved on to a local bike shop that was very helpful and had a Diamondback that was nice but it was a 20" frame with 27.5" tires, which is a tad too large for me. So since its Sunday and every other local bike shop is closed I went to Walmart just for shits and giggles, mainly to sit on a few different size bikes. I ended up getting a new tire tube just to make my current bike useable and I'll go out and Friday and continue the search.

Well in a turn of events, I just took my bike out with the new tire tube, this time filled to 40 PSI.. and it pops after ten minutes. Turns out the outer tire is ripped right at the bead, exposing a metal bead ring which was slicing the tube open. My brother in law just gave me his Schwinn mountain bike that he has used all of two times, its about ten years old and in great condition. I rode it around for an hour and it was way way better than what I had. So back to my plan to ride this thing around save up some cash and then find something a bit better.

For what it's worth (this wasn't the problem this time) you generally want 22-28 or so PSI in a bike tire.

you can actually inflate your scrote pretty safely with sterile saline, syringes, needles, and aseptic technique. its a niche kink iirc

the saline just slowly gets absorbed into your blood but in the meantime you got a big round smooth distended nutsack

you're definitely getting the Cheap Old Bike experience. random poo poo failing in weird ways cause it sat outside for a decade or more and now you're riding it a bunch. my first city bike was my childhood department store mountain bike I took with me to college, and i rode and repaired it until some poo poo i couldn't fix finally broke (I bent the axle jumping off a train platform during critical mass)

Is this for more off-road, on road, or both? I have more of a thinner tire with somewhat aggressive tread, its certainly not any of the fatter tires I saw on the nicer bikes.

I've been riding for about an hour each day trying to get my leg strength and endurance up cause I'm an out of shape piece of poo poo, but I took to the local woods today. Everyone around my neighborhood seems to be maintaining the trails and everything isn't over-grown yet. I really need to work on my front tire hop, which I can only get about 3-4 inches off the ground. Also need to get a better gauge on what gears I should be in when doing things. I typicaly stay on the middle gear for just about everything and stick to the higher smaller gears when riding around on pavement. I kick it to lower gears while going uphill, but even that didn't help in the woods with roots and bumps everywhere. I'm sure my current physical level isn't quite there yet. I'm having fun and even though this isn't the best bike, it'll do what I need it to for now.

I had mountain biking in high school, and generally just rode a bike when I was young so I have some idea of what I'm doing. But fast forward twenty years of bodily abuse and cheeseburgers, and I kinda just suck at stuff now.

For off-road. On-road maybe a little more but if it's a mountain bike you want to optimize it for trail riding basically.

I'm 5'9" 180ish pounds trying to get to 165-170. The only reason I went up to 50 was because the tire claimed 45-60 PSI so I figured 50 was on the safer side. I am not too familiar with tube tires though so any information is helpful.

The numbers printed on the tire are the maximum pressure it is designed to withstand and not representative of what is good or useful.

We are roughly the same spec and on inner tubes I’d be looking at high 20s to low 30s for pressure based on how smooth or rocky the trails that you ride are. With inner tubes you have to balance squish and grip vs too much squish will result in pinching the inner tube between the tire and wheel rim which leads to ripping the inner tube. If you put too much pressure in the tire it’ll ride like crap as in bounce off of obstacles vs deflect over them and also you’ll lose lateral grip which leads to sketchy cornering.

Finding the correct tire pressure is a bit of an art; basically you start at a sane baseline for your weight and trail conditions and adjust to preferences as you go until you get a feel for what 28lsi feels like vs 30 or 33 and then you can get into advanced topics like front vs rear.

Personally I like my front to have just a little less pressure and therefore more squish than my rear unless I’m riding in muddy conditions in which case I might sacrifice rolling resistance for as much grip as I can get without risking bashing the rim on a rock or root or having the sidewall fold over whilst cornering. On tubeless on a really messy ride I went down to like 10-12 psi, hills were a slog but the downs were magnificent even when I was two wheel drifting around corners!

Edit 2: Yeah there are tubeless tires and they are amazing.

Note: tubeless tires require compatible rims but you can often get take offs on consignment at your local bike shop for low $$$ vs buying a new set or having a set built.

Tires don't really come off rims and people who want to ride on sand (sickos) can ride fatbikes with huge tires at low PSIs (probably closer to 15 or something I dunno).

:pirate::hf::tinfoil:

I think some super wide fatbike stuff on snow or sand is crazy low like 5-8 PSI.

Weight and tire volume (size of the tire and diameter/width of the rim contribute) makes a big difference in reasonable pressure, back when we ran skinny rims with 1.9"/2.1" tubed tires, off-road pressures were like 25-35 but now with 2.3-2.5" tubeless its like 20-30 (super-rough numbers, lots of factors come into play plus some people like super low pressure and some not). Additionally, you can get away with less pressure using tubeless because you don't have to worry about pinch-flats (smashing the tube between the rim and a rock or curb). They sell foam tire inserts that allow running even lower pressures. Generally, lower pressure has better grip for offroad until you get flats or the tire starts to get squirmy and feel 'flat' even though it is holding air.

Anyway, if you want to get a decent starting point for pressure you can use a calculator that takes into account tire size, rider/bike weight, terrain type etc like https://axs.sram.com/guides/tire/pressure. Maybe flip around between terrain types to get an idea of what is reasonable, but you can probably go up or down like 25% from the recommendation without catastrophe.

They really don’t de-bead thanks to the Kevlar cords in the tire beads, but they will just go flat and if you ride them enough like that (say in an emergency or racing) it’ll chew through the sidewall just like a car tire.

Also stop now while you still can, this hobby is a total(ly fun and worthwhile) money pit. I sat that just having bought what I thought was just going to be a hub upgrade for my hardtail that turned into a full wheel set plus fork! Thanks to the NICA discount and my very accommodating friends at the shop this only cost a mere *cough* $1200 and basically doubled the price of the bike overall but I got a better fork, 5x110mm through axle (vs quick release) and a DT Swiss 350 54t hub on lighter Royal rims wrapped in a blackwall Purgatory up front and a Ground Control rear.

TLDR is I now have a decently racy 29er hard tail to run the spring short track series on and teach kids how to race hardtails (once I learn myself that is).
