Where can i order a 26 inch rim for my schwinn meridian tricycle, since it's badly wobbling from 6 broken spokes

One of these may work. Measure distance through hub and diameter of hole, then call to confirm compatibility. A Schwinn dealer will be able to order but may cost more.

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).

This is a very complex operation. I suggest you contact or take your trike to the local bike shop

I just put my Maridian together and two days later hit a small pothole on the left rear doing about 15mph so I called Schwinn and they replaced the wheel with no hassle. They have mnfg standards and a lifetime warranty...

The trike uses a band brake, refer pages 25 and 26 of the user manual http://www.schwinnbikes.com/media/uploads/blog/files/Schwinn-Meridian-Manual_Mar2011.pdf The Schwinn dealer should have a replacement in stock or be able to order one in for you. You may also be able to purchase one from eBay if you measure what size you need.

The real problem is with the lack of serious fender mounting hardware from Schwinn. There needs to be a solid one piece brace connecting both fenders and attaching to frame at the seat support.

These fenders will wobble and bend with little or no effort or pressure. A SERIOUS DESIGN FLAW!!! SHAME ON SCHWINN ENGENEERS

This might help...

The rear brake may be locked up. Page 26.

Local bike shop may have a way to find one and install it for you.

If your hubs are good, a good bike shop should be able to rebuild the wheels with new rims and spokes. This probably will cost more than a similar sized wheel for a 2 wheel bike.
