First Row
• Training Wheels, Balance Bike, or Gyrobike?: This is a great article from Babble that will explain the basics of what's out there along with a strategy for teaching.
• DIY Balance Bike: We recently posted about this idea, which is really how the first "balance bike" idea was birthed. Lower the seat and take off the pedals and voila- instant balance bike.
• The Float from Trek is a great option because you don't need to buy a separate balance bike- just remove the crank- it's made especially with this idea in mind.
• Strider Running Bike is a fairly affordable and popular option.
Second Row
• The Wishbone Running Bike isn't cheap but it does grow with your child giving it an extended life.
• The original trend-setter- the LIKEaBike and its newest companion, the ROCKaBike.
• GrowBike Another interesting option that is actually a few bikes in one.
• Skuut Balance Bike: Another really popular one with mostly good reviews.
• Smart Gear Wooden Balance Bike: This one's available at Target.
Whichever direction you choose, there are definitely a lot more out there than when we were growing up!

We bought the Trek Float bike last year, and it worked like a charm! Our (now) six year old had bike riding down after a month or so of balancing on it, and then we just popped the pedals on and she rode around on it for the rest of the summer.
Now that she's moved up to a bigger bike, we've taken the pedals off again and our five year old is scooting around on it. I love the versatility of being able to take the pedals off and put them back on again!
Just an FYI: Your link to the Smart Gear bike from Target is not directed to the correct bike.

But you can find it even cheaper here!

we got the uber-affordable weeride from amazon last year. it was on sale for ~$30. Right now it's at $70 but I'm sure it will dip soon:

We just took the pedals off of my daughter's (four year old) little huffy bike, but she still couldn't quite touch the ground for riding a balance bike. So then I went on Ebay and found a really small little old radio flyer with great flat wide tires which I won with a .99 cent bid (and then paid $20 in shipping for). We took the pedals off that, my daughter spent three days getting used to the balance and, after she could coast the whole way down the driveway we put the pedals back on and away she went with one little push. Easy Peasy. After a week of the little radio flyer, she's back on the blue bike with the pedals on... she likes the brakes better on that bike. So much easier than trying to just do training wheels... which is what my son did when he was ready to ride a two wheeler (years ago).
Trek Float, but you know, it's a 16", so when you take the peds off, you need to make sure your tot can actually use it as a balance bike -- feet on the ground, legs slightly bent.
We picked up a Weeride from Walmart for $19 - my 21 month old gets on and off by himself and is starting to glide rather than just walking while on it. It is rather miraculous how it is working!
We purchased the Strider Running Bike last year for my son's 2nd birthday. He was obsessed with big kid bikes, so we wanted to get a balance bike that most resembled a real bike. He's loved it since day one and his favorite thing in the world is to take it to the local skate park and ride it down the small ramps. I love the looks he gets when people see a 2-year-old "riding" a bike. We've been super pleased with the quality - he's wrecked a few times and he throws it around, but it still looks virtually new.
