I recently picked up a very inexpensive ($60 on sale at Target!) Instep Quick N Easy trailer for my wife and I to use to haul the kiddo around in. So far, it's been less than easy. Setup of the trailer is a breeze, but I can't connect it to the bike.
I have an Giant OCR 3 (2007), which up until now, has been perfect. However, when I go to mount the hitch/coupler for the trailer, the frame tubes get in the way. It's a little hard to describe, but I attached a picture on what I'm talking about.
On the left side, the tubes from the frame stop right at the quick release skewer. There is enough room for the quick release skewer to fasten, but there isn't enough space for the large adapter for the trailer to sit and the skewer to tighten back on. I'd say it's about 1/8" of an inch on both tubes that it's not clearing by.
I've looked for a replacement hitch/coupler, but InStep is no support. Other than the dremel, I can't think or find some other way of mounting this $%#& thing. I'd rather not dremel it (the coupler, NOT the bike!!! ), as I fear that it may weaken the hitch. Last thing I want is for the trailer to take a dive with him in it.
The trailer also came with a fancy dimpled & tabbed plate that meshes with the coupler (I'm suspecting that it's so the coupler doesn't 'spin' once mounted; the tab on the plate sits tightly against the frame or in the mounting hole for the rear rack). This doesn't fit anywhere on my frame. It meshes in between the skewer nut and the black coupler. See link for a picture.
I'll check out the LBS tomorrow for ideas, but I'd hate to have to get a different trailer just because this thing doesn't mount. I have a strong hunch that anything skewer mounted won't work anyways, which limits my cost options. My son was the reason I didn't get out much last year to ride, (he was too young for seat/backpack) and I'd hate to spend $200-300 on a trailer to find out he hates it. ($60 is a perfect price for this experiment--there's always craigslist/ebay and the losses would be minimal.)
Wife's bike is the same frame design (also a ocr3). Besides, the trailer is my handicap when we hit the hills.
