Hello all, I'm sure a bike exists that matches what I'm looking for, but I'm still relatively new to biking (about six months at this point), and there are a few things I simply either don't know how to ask for, or I just don't know what's out there.
I should also note that I don't need anything fancy or cutting edge; I've been using a Concord New Yorker from the 1980's and would use it indefinitely if it could do what I'm about to ask for.
I basically would like to have one bike for the entire year (I live in Wisconsin, so what is ideal for summer here may not be so ideal for winter). I would like to be able to have 26 x 1.90 (or wider) wheels on my bike in the winter, and something like 26 x 1 & 3/8 wheels for the rest of the year. What's more, I'd like to have coaster brakes on both wheel sizes (easier to maintain in the winter, plus I just enjoy them!). I have no experience using a chain tensioner (if I'm forced to have a frame with vertical dropouts), but I'm willing to learn.
One of my foremost worries is if I can even get a good coaster brake rear wheel at wider than 26 x 1.75 ... all I've seen online is from Wheel master, who apparently aren't very good. Would I be better off buying a coaster brake hub and having a LBS build a wheel at the desired width?
And as I'm guessing nobody is making bikes that come standard with coaster brake wheels in such wide widths, will I have to simply buy a frame and add my wheels on? What should I look for in a frame to ensure both sets of wheels will fit? (I'm also VERY open to cannibalizing older frames if something already exists that would work for me).
Sorry that was so long-winded ... thanks in advance for any help!
