Onroad an off road, I've seen a variation of wheel sizes. 20" 24" 26" 27" 700mm 28" and 405 and 412
(I think the last 2 number are correct)
Question #1 (easy one) does 28" = 700mm
Size matching body. I'm 5'5" on a good day. Watching taller/larger riders on 26"-700mm, by porportion,
I should be on a 24" wheeled bike onroad or offroad. But selection seems limited. I've seen a small
20" wheeled bike with suspension that looks like it would be extremely manueverable offroad. Likewise,
I've recently seen road bikes with relatively normal sized frames that have 20" wheels.
Question #2 What are the pros and cons of larger and smaller wheels?
The only arguments I've seen lately is rotating mass, ride quality. I would guess that a 20" road bike
would be a rougher ride but I'm not sure on speed (if it really IS faster, I'd guess there are a few
who would take the rough ride and squirly handling). It takes an act of god for the masses to alter
I remember the manueverability of the BMX and I am facinated with a 20" bike with front or full
suspension, (mabie) with a frame slightly larger than a BMX for offroad use. It would redefine the
term, turn on a dime.
I'd also like to see quality 24" wheeled road and mountain bikes. With most lines I've seen, the smaller
frames seem like an afterthought, good enough, but not really that good.
