Hello, I am very new to this forum website so please forgive me if this question has already been posted.

I have https://www.performancebike.com/bikes...0_20000_400330
had that bike since 2010 and I have used it from commuting place to place. Now I want to how much this bike could handle (mountain biking) I want to start going on downhill trails with this bike. I plan on doing something like this https://www.pinkbike.com/news/mount-s...ails-2009.html (the first video)

Thank you for your time in answering the question or even reading it.

That's a recreational mountain bike. It's not for anything with the description "gnarly" in it, as per your second link. If you ride as slowly as they did, sure... but they're doing that on purpose so viewers can see what the trail looks like. At normal pace, they'd be going fast and hard.

So stick to fairly mellow trails that don't involve full-face helmets, jumps, drop-offs and power slides.

The answer is no. You'd want disc brakes for serious DH, and I think the fork is a no namer.

You want a good fork, preferably with 70 cm. travel. Rear suspension would also be nice.

i think you can do it. you can ride your bike on that trail. the trail in the first video isn't really that technical or downhill-ish. you are a new rider, so you will be more careful and more conservative with your riding, your skills aren't good enough to do anything too heavy right now, so, given the way you might ride that trail, i think your bike can make it. i say go for it.

if you want to really really ride rocky gnarly trails, with drops and such, you will eventually need a better bike.

yeah, disc brakes are awesome, but i remember riding many many many years on some pretty hefty trails (the portal in moab) with my hardtail and v brakes.

i say go for it. understand there is a high chance you will break your current bike, but it's not definite.

i would post this over in the mountain bike section.

I'm with Pablo. My early bikes, more than 30 years ago, were low end and garage sale junk. I live in the Sierra near Reno, and I rode everywhere. Nobody had suspension, and you had to RIDE, not just sit and pedal. Put on somedecent tires, learn to take the shock with your legs, and have some fun. The first road that pops up on your link is nothing--I'd do it on my road bike with a change of tires, and I'm 67 years old.
Your bike isn't ideal for that, but it's the bike you have. You don't have to do everything at 40mph. Go for it.

DH bikes have forks at least twice if not three times as big as a cross country bike. More than likely if you read the manual on

your bike you will see it is not for DH. You might get away with it but you would have to be a lot more than a newbe and you will more than likely destroy the bike. Simply go to any LBS and ask to look at a DH bike and see what people are riding DH and compare it to what you have. You will get your answer yourself.

Pardon me for saying, but this lot are talking a right load of bs. I started mountain biking in 1993 with a Raleigh M-Trax Ti-1000. Fully rigid and tektro cantilever brakes. Back then mountain bikers required something called "skill", not friggin suspension or disc brakes. I took that bike on downhills too and wupped many an ass on it. Your bike is more than capable of any knarly downhill you can throw at it. As you get faster you may need to upgrade, but for now, I dare say it'll take any punishment you throw at it.
Its not the bike, its the rider. End of!

You will break the forks almost immediately. The old timers rode bikes with rigid forks, which are way tougher than budget mtb forks. That said, give it a shot.

You have 2010 Fuji Adventure Mountain Bike with Suntour M2000 forks. That is perfectly adequate for riding down slopes but dont do any big air jumps or try and ride as fast as you can into logs and rocks. The fork will bottom out on anything bigger than little hops.
I have ridden highly technical steep slopes on non suspension Trek 850 hire bikes.

At the very least, have someone check the tension on the spokes. At $300 the wheels won't be that strong, and I doubt the shop prestresed and retrued them when new. A quiet ramble down the trail would probably be OK, but any kind of big hit, and I think you will lose multiple spokes, and possibly taco the wheels.

take a little risk .. but wear the safety gear.. helmet, gloves, safety glasses
to keep stuff out of your eyes. don't let the speed or abuse of the bike go too far.

might end up somewhere you have to walk a broken bike, thats just part of the deal.

bring along a couple friends with the ability to carry out the wounded..

Know top brand Full suspended is 4 figures.. $XXXX.xx

Just came back after a couple of days to see what other people had to say...
I'm sticking with my original post. Your bike isn't ideal for what you propose, but it's there. Many relatively new cyclists (I've been riding for more than 40 years as an adult) have inflated ideas about what you actually NEED, rather than what would be nice or what would make the ride more comfortable. My first mountain bike was a $300 Mongoose, rigid everything, and I rode it thousands of miles, everything from technical stuff to a couple of road centuries (I changed the tires for those...). Just get on the bike and go ride. But do keep an eye on those forks.
