20 Most Recent Schwinn Meridian Adult 26-Inch 3-Wheel Bike Questions & Answers

You should be able to go to a bike shop and they would be able to cut a length to size for your bike if not I have had luck lawn mower shops they do carry chains

Best to check with Schwinn dealer, but almost any decent mechanic could assemble without instructions. Would be very unusual for the bike to be very disassembled unless someone attempted to repair it. Parts are mostly the same as on a regular bike, other than the parts that help to drive both wheels.

Its a regular 26 inch wheel. Just get a replacement, take the old one off and slide the new one on.

Hello!
You will need to remove the two bolts and nuts/washers that hold the wheel axel in place. After that you can pull the wheel off the frame with a little force. See the image below where two bolts that hold axel on both side are.



The bolts are square near the end and will go into a square hole or cut out in the bikeframe. Putting these bolts on is a bit difficult at first, but once you have done it, its basically easy.

For the rear wheels, the right side axel is shaped like a "D" (not round) and will only take the corresponding wheel with the "D" axel area. The other rear wheel has only the special bearings for its axel and no "D" area.

Seat posts and clamps are a generic item, not specific to any particular bike. Just check with a bike shop, or alternatively Walmart, as they sell Meridians. I’m happy to help further over the phone at https://www.6ya.com/expert/donald_f2ed37026a3ac881

It could be one of many things,The first Thing I would do is check whereabouts the noise is actually coming from,ie lifting the back of the bike up with a help of a friend and spinning the wheels one at a time and after both wheels being spun rotate the pedals and see if its coming from the gear cog at the rear,Whatever is the problem the part needs to be cleaned out and a new part put back on.It may be just a cracked ball race in one of the wheel spindles.

check the Bottom bracket, if no obvious rubbing of the front chain rings. Bicycle Parts Glossary

Usually 5/32, but often better to replace the pedal than to attempt overhaul, as they are not always easy to repair. Also, many people assume that various problems (clicks especially) are due to pedals when it is actually something else in the crank area.

try another bike shop, sounds like they don't want to deal with it. "riding on the rim" generally shouldn't affect the hub and bearings, at most the rim can be relaced. Although to have a competent wheel builder do this may end up costing more than replacing the wheel. A good mechanic should be able to use a regular 26" wheel and replace the axle with your canti-lever axle to get it to fit on the trike (I say that without looking at it, so I'm just making an assumption here).

No, schwinn has different specs from most bikes; http://media.schwinnbikes.com/media/s/c/schwinn_meridian_manual.pdf oe see http://www.bikeforums.net/utility-cycling/701831-schwinn-meridian-trike-info.html

The brake pads should be "toe'd" in, that is, the front part of the brake pad should touch the rim first when the brakes are applied. This should only be an adjustment of 2-3mm when you look at the pad compared to the wheel rim.
Another possibility is the age of the brake pads. As they get older, they get harder and lose their pliability. Their harder surface can cause squeaking, and poorer braking performance. You can try sanding them down with coarse sandpaper as a stop-gap, but for the relatively low cost of new ones, replacement is a much better option.

I am not familiar with this model of bike. I guess there are two possible reasons: 1. The axle was internally weak. It may be either due to its small diameter in the centre area or faults in the metal body. 2. The load was too heavy. Depend on the weight of the rider or any additional people or goods on the bike, the total load may exceed the load limit and the axle broke.

Your best result would be to take your bike to the nearest bike shop for proper repairs

Bike chains are slightly different determined by amount of cogs on rear sprocket. If you havent changed the chain, adjust the tension of chain.If tension is ok-sprocket would be damaged(teeth worn,slightly rounded)but if same prob on different gear, chain tension/incorrect size chain is problem.Hope this has been helpful..

Any time a chain comes off it means there's slack in it or something's not tight enough. Not looking at your bike, I would have to guess that you need to loosen the bolts on the back wheels and then pull the wheel assemblies back until the chain is tight. This is probably a two person job, one to unbolt and bolt and one to apply tension. That being said, many years ago I remember bikes my friends used had a problem where if they were riding at a good speed and then stopped peddling to coast, then slightly reversed peddling, then started fast peddling again, that they would throw a chain. I think what was happening was they were creating slack in the chain by coasting, slightly reversing their peddling, then starting again. The chains were also slightly gummed up, allowing slack at this time.

There is the way to remove the link of chain, but for that you will need a special chain tool. You can buy it on ebay, or, go back to Walmart and ask for proper sizing.
