OK, I've talked with the boss lady, and bikes are the way to go vs. scooters or Striders. Any suggestions of brands or would any Big Box bike do? Are there some good values to look for in the Big Box stores? I was looking at the treks, but they are expensive and their resale value is dismal--and really the kids don't care about the names, they'll be excited to just get their first bike! I could look at used bikes but I just don't trust them.
I'm also convinced that training wheels are evil. For the parents who went without training wheels and used the bike as a balance bike, did you take off just the pedals or the whole crank assembly?
