The 7-speed gear on my Schwinn comfort bike is making grinding noises and occasionally binding up when I coast. Do I need to replace gear and rim?

If your bike has a traditional spin-on freewheel, you can replace just the freewheel itself. If however your rear wheel is equipped with the more modern and common freehub, you will likely have to replace or repair the hub or entire wheel. A few drops of oil inside the assembly might fix it up for a time, if you can manage that.

I've had the bike about 18 months. Shortly after I received it, a clunk developed. I called Schwinn. They sent a repairman and he replaced the flywheel bearings. It is a task. I doubt he could have done it with out my help and some special gear loosening oil (Kroil) which I had and he used at my suggestion. It was repaired under warranty at no charge. It has worked perfectly since. Hope this helps.

Sorry, we had no trouble at all with this bike, either upon shipment, during assembly or during usage. I suggest you take it to a good bike repair shop in your area and ask the question. Good luck!

I do believe your present bike is also a 7 speed as is the freewheel your giving thought to purchasing.A special tool is needed to remove the current freewheel from your wheel.Best option, take your wheel and your new gears (freewheel) to a bike shop.They'll swap them out for a few bucks.Check the chain length after you replace the wheel.That freewheel is a good. I bought one myself.Ride safe. Have fun !

Hello. I did send the bike back. Amazon's service was great, once again. The left hand grip was tearing in two places. It had a total of three hours use. The chain drive is very loud. There is no way to fix that. New road bikes don't have that noise. This one gear spinner should not be so loud. I liked the elbow pads, however that is a where the hands go. One of the pedals came off and was stripped. It would not go back on. I know I put it on correctly. For a new product this should not have so many problems. Spend a little more and get a quality product. I got what I paid for. Hello. I did send the bike back. Amazon's service was great, once again. The left hand grip was tearing in two places.

Since I replaced the bottom bracket with a sealed cartridge, I've had a similar problem. The looseness is on the right side at the bolt closest to the bottom bracket. Although the problems is with the bolt on the right side, that makes the pedal on the left feel loose.But I recently replaced the wedge pins and it seems better now. I may have had the pin facing the wrong direction. If you put in all the pins facing the front, half of them will be backwards!

Sounds like a defective unit. Mine is solid. I've commuted over 1000 miles in the last year with it hasn't had any issues.

Same problem here - I love the problem with your bike comment...mor pressure on the tire is not the solution. Every other Mag trainer I have seen has a resistance adjustment. Basically on the highest gear it is just getting enough resistance, and then the rear wheel is moving the equivalent of 30+ MPH... will return.

I have an old World Traveler Schwinn! I bought the tires. the rubber band for the rim and a new tube! Very easy to install and they fit like a glove! My bike is over 36 years old! Enjoy!

Gear came with the rim. I watched a youtube video on it, which help make it go smoothly.

I make sure to place lube on the track and I sprayed WD40 were the "pedals" can be adjusted. I also took the plastic covering off were the arms attach and realized it was the source of some of the noise. I WD40'd that area and replaced the covers. The noise or grinding sound stopped. Occassionally I still spray WD40 on the pedals. Ultimately you can call in the warranty folks for some troubleshooting if it is still a problem for you. I have had my elliptical for over a year and aside from the occassional noise it gets a lot of use!

You must take apart the handle and adjust the gear by spinning it clockwise, then replace the little washer, put the crank handle back on and test it. If it is grinding very easily then your gear is too loose.

did your spedo work properly before the gears went bad? then the orientation of the gears may need to change.go in same way they came out.are you using one of those-your speed is machines from local police -to know what you speed is? did you change the tire size?

Yes that sounds about right in the turbo mode. But that will affect your distance depending upon your terrain. The manufacture gears are for pretty much flat terrain. Optional gearing will solve the problem but again at a cost of distance. Mine is for sale because we moved to a heavy traffic area with no bike lanes.
