I need a front rim assembly for a mongoose spark 26" X1.95 dual disc brakes. i purchased this bike at wal.mart north Olmsted, Ohio 44070. the bike was hit at the front rim is bent beyond repair. i am looking for a replacement cost and shipping. thank you.

Hey, Local bike shop determined that both wheels were defective. I took the junk back to Walmart and got a refund... PROBLEM SOLVED!!

Thanks.

adjust the cable at the brakes or and piece by turning the retainer that holds the outer cable case

the brake pads just need to be adjusted. angled so the pads hit the rim on the back of each pad first. right now the front of the pads are touching the rim first and making a squeaking noise. very common and very easy to adjust.

First turn the adjuster on the rear brake handle all the way in and make sure the slots on the adjuster and set nut are lined up, pull the brake cable out and leave it attached to the lever to open the rear brake pads, loosen the bolts on the tire and pull the derailer up to remove the tire, remove the dustcap from tube and using a flat tool (Wal-Mart has tire tools for $1) take one side of the tire bead out of the rim, pull the old tube out, place the stem of the new tube in the hole and put the cap on, tuck the new tube in the tire trying to keep it flat as possible, push the bead of the tire back into the rim. before inflating the tire, put it back on the frame while pulling the derailer up to get the chain back on the cogs( they will adjust later) tighten the bolts and inflate the tire to desired pressure (between 35-60 psi)

They don't sell to the general public. Go to the store where you bought it and ask to order from them.

It's prabably easier to buy a whole new hub. And for ablout another $20 you get a whole new tire. You should do that. Have a bike shop do it because it can be tricky.

For the gear problem.Find the shifter.Use a pair of pliers and loosen the nut where the cable is passing through the shifter.Now withe the pliers pull the cable tight.Very tight.Spray the shifter with WD-40.That should fix it.


For the front rim,tighten all the spokes.Pliers will work,but a spoke too; will make the job faster.

The chain guard is usually fastened to the seat tube of the bike (the frame tube coming up from the pedal area to the seat) with a plastic band. If this band is broken or missing, and there is excessive play in the chain guard, I suggest removing it entirely or returning the bike as it may be a hazard.

Try calling the manufacturer of the joystick. It is probably a P&G drives joystick. Here's their contact info. PG Drives Technology Inc2532 East Cerritos Avenue

The cheapest way is to buy a new tube to see if that was the problem. Sometimes tubes can inflate bigger at one area than others. If not check to see if the rim is true, meaning that it is not bent, if so replace. It could also be the tire.
