    16" vs 20"

    My son seems to big for a 16" and too small for a 20"

    he is currently rocking a strider but is way to big for that as well

    So, I guess we get the 20"......

    I'm in the same boat.
    By the way, you can buy 18" wheels to put on that larger frame.
    I saw a bile at the store just the other day that had 16" wheels on it that should have had 20's and my son was riding it around and it fit surprisingly well.

    Interesting.

    I might steel the neighbors bike and try that.

    Grandpa has already bought the bike. They had one with gears suspension fork, but that just seemed silly.

    What bike is in the second pic? At first I thought it was a Street 20 but it doesn't have a front brake as pictured on Cannondale's site?

    How tall is your son and what is his inseam length?

    My five year old son started riding a Hotrock 16 on his fourth birthday and looked big on it within six months, although he still rides it.

    He's 46" tall with an 18 1/2"" inseam. I'd guess he was under 44" tall when we tilted the BMX style bars on his Hotrock as far forward as we felt we could.

    My 42" tall four year old is able to ride the Hotrock 16 very comfortably. His inseam is 16". We adjust the seat but leave the bars tilted forward when he rides it.

    We measured their inseams as recommended by Islabikes.com. Used a 24" level instead of a book.

    it is a Cannondale Trail 20 Single speed

    I am not sure his measurments. He is 4.5, but pretty big for his age

    Interesting. The Trail 20 SS is listed as having a front V brake and rear coaster brake. Must be a country by country thing.

    Just so you know, the Cannondale Street and Trail 20's with gears have slightly different geometries than the Trail 20 SS. If I remember correctly they run bigger so if you think he's borderline small for the 20 the SS might be the better choice.

    yea, we are going to go with the 20" single speed.

    If I want gears later, I guess I will have to build an internal geared hub.....
