Need help reviving my bike

First off, I am new here! Hi!
I created this account to ask this question...

I have an old Supercycle Ascent and want to bring it back to life. (my parents bought it for me from a garage sale for $20)
I would get a new bike but I don't have that much money, I want to get into dirt jumping but I don't think that this bike would be able to handle that. I have gone down a few trails/makeshift jumps in my neighbourhood and had many falls and crashes that caused these problems...



1) The front brake is messed up (Can't see it in the picture but its bent) :



2) Both brakes don't really work well, I am guessing that new brake pads would help? (Pictures are of back brake) :



3) Seat is ripped (Simple thing, just thought I would point it out) :


4) I have to mess with the gears to get them to switch:




So, the main question is:
Do I fix it (How do I fix it?), or wait until summer (I live in Canada and its already -6) to save up and get a new bike?


(Sorry for the bad pictures, I took them with my phone and had to use flash because it is dark out. Stupid daylight savings time in Canada...)

I will also add that this is my old "BMX"...

Your brakes were "messed up" from the factory and need some work now. That bike is suitable only for sidewalks and gravel trails, at low speed. You have a paradox: the bike needs work but is not worth spending money on. Maybe you should consider learning to fix problems only as they occur while just riding it gently (say back and forth to the part-time job you will get to save up enough to buy a better bike).

Also, lower the stem and stop jumping on it.

Save your money and get a new bike. Visit BikesDirect.com. Mountain bikes are not designed for dirt jumping. If you want a bike for dirt jumping get a bike designed fot it.

1. The photos indicate at least one brake pad that is badly misaligned. You can probably loosen and re-align each pad with a 10mm open or box end wrench. Position the pad so that when you apply the brakes, the pad is centered on the rim. Then tighten it finger tight plus an eighth to quarter turn.

2. Next, lift and spin each wheel in turn. The clearance between the rim and brake pad should be about 1 mm and should be exactly the same on both sides. Start by centering the brake on the rim. Sometimes this can be done by loosening the mounting bolt and turning the brake assembly until it's in line.

3. If that doesn't work (no need to force it, it either works or it doesn't), you probably need to release one side of the centering spring or the other, then bend it to correct the difference in gap. It's not that hard; you can easily free the spring from its retainer on either side by pushing it toward the rim, then pushing it toward the center of the bike. Think about the way it needs to be bent to increase or decrease tension on that side, then do it.

4. After you've got the clearance on both sides roughly the same, loosen the cable nut where it attaches to the brake arm. With the cable loose, squeeze the calipers until they touch the rim. Lightly tighten the cable nut until it just holds, then let go of the pads. If you're lucky, you'll have that 1mm of clearance on both sides and you can finish tightening. If not, undo the bolt, adjust and re-tighten.

5. Repeat steps 3 and 4 until you've got it perfect.

Regarding adjustment of the derailleur, you can do that too, it'll just take a bit longer. Because you said you've had a few wrecks, I suspect your derailleur hanger may be bent. Unless you have the proper tool, you'll need to take it into the bike shop to get it aligned. While they're doing that, watch a few videos on "adjusting a rear derailleur." And then watch a few videos on checking chain wear and sprocket wear.

The best advice I can give you is to ask a savvy friend or uncle to watch over you as you work on your bike, offering assistance and help as needed. It's more than I had, but I figured it out. You will too. Unless the frame is broken or critical threads are stripped, most any bike can be repaired. Good luck.

Bad news: The bike is a complete crap-roach. Don't spend a dime on this thing.

Good news: Ride this bike to death. Go crazy.

Save up for something better.

I'm going to go against the crowd and say keep it. This is a perfect chance for you to learn bike maintenance that will serve you well for however long you ride.

Like the others are saying, this is NOT a bike for dirt jumping. It is sort of a hybrid.

The saddle tear is no problem. Ignore it, duct tape over it, or get yourself a cheap replacement from a thrift store or a bike shop, who usually have tons of extras from when they sell new bikes and immediately swap in a new saddle.

Are the wheel rims made out of steel? If a magnet clings to them, they are. Steel rims tend to brake poorly, especially when wet. Also, that type of brake caliper is probably not going to offer very strong braking to begin with. You will need to be careful to know the bike's braking limitations and set it up for the strongest possible brake performance.

Get yourself some grease, pull the seatpost all the way out (if you can move it), and grease the seatpost. Then reinsert it. This keeps it from getting corroded and stuck in place over time. An ounce of prevention is worth a pound of cure.

Put a drop of oil on all of the pivots of the brake calipers. Be careful not to get any oil on the rims or brake pads or your braking will go to hell.

Resurface your old brake pads. Take them off (carefully inspecting any washer or nut placement) and sand a little bit of the face of the black pad's braking surface to get rid of old, glazed, ineffective outer layer. Put them back on the brake arms and make sure they're correctly aligned with the wheel rim (Park Tool reference). Wash your wheel rims with rubbing alcohol to get any old grime off and restore best possible braking. (And to make the bike look more awesome.)

off topic.. sorta...!

I was out mountain biking at a local park and came across a bike/skate park. Most kids were on their BMX bikes doing jumps and flips, but there was another kid with an el cheapo brand of bike. He decided he needed to do something to attract attention with his piece-o-crap bike, so he rode it as fast as he could towards a ramp and jumped off at the last second and let the bike launch! The first run almost cleared the fence. After the laughing died down he banged parts around so it would roll again and did it again. This time it DID clear the fence! Of course the bike was beat to death but since it was cheap there was no loss. He and a couple of other riders tried to do the stunt again with no sucess, so I couldnt get a video. I think that was the perfect use for a cheap bike.

I hope the OP gets a much better bike to ride PROPERLY for whatever style it is.

Bike on!
