Yesterday, wife and I (under a bit of my prodding) said forget waiting for birthday in September (too many rides would be missed between then and now), and got my daughter, who will be turning 8, a new Myka XS (13" frame) with 26" wheels.
I had gone with the 24" Hot Rock for my son when he was turning 8, and though this time the full-size wheels and XS adult bike was the way to go.
First of all, my daughter has been a little tall for her age, but not a lot. She is a tough little thing, and VERY strong for her age (has to keep up with her big brother).
Anyway, I ordered the bike through the LBS and figured I would let her ride it, and ride a 24" kid bike, and see what stood out. She had never used hand brakes, and was going from a little kid bike she had outgrown about 6 months ago. A little tough getting on the new bike at first, but she just started cranking. The bike looked HUGE at first. But she was not the slightest bit intimidated. There was never a doubt, the bike was going to come home with us.
This morning, before I even knew she was up, she was out riding, with helmet gloves and long pants (as the LBS guy suggested). She already has the thing nailed. "Dad, this is the best bike ever!". This dad was SOOOO stoked! So, if you see a super cute little girl on a blue Myka on Bend trails, say "Hi Addie".
