My son is about to turn two and he really likes the Skuut Balance Bike, but is this functionally any different than a small Bmx bike with no drivetrain?
Update
Specifically, is a run-bike designed to be easier to balance (e.g. by changing the distribution of weight relative to a bmx bike)? by the way, I was thinking of bmx-style of equivalent size, not a true 20" bmx bike–
Since my original post, I have found that this type of bike is called a 'run-bike' and that they are made by multiple companies. However, I have never seen one in a regular bike shop.
Knowing the generic name, it was easy to find the wikipedia site and answer my own question 'no'. But I am still open to the possibility that there are differences.
I have found a related but distinct question on the best method to teach a child to ride a bike
Update 2
My son received a Kinderbike for his birthday. I decided on the kinderbike based on this NYtimes article and some Amazon reviews that suggested that the Kinderbike is of better quality than the Skuut.
Review
Indeed the Kinderbike uses 'real' (if cheap but sufficient) bike parts, including a real brake and headset. It even comes with a bell! I don't want to talk up the quality too much - while certainly better than what you might find at a box-store like Walmart (those bikes are often non-serviceable), but nothing like what you might find on an entry level adult bike. Out of the box, the rims were out of true, the headset was on too tight, and the tires smell like plastic fumes. But this is all fixable since the components are basically like a regular bike. The Skuut, on the other hand, apparently has plastic washers and cheap tires that make the bike overall not as durable. Although I prefer the aesthetics of a wooden bike, common sense chose durability.
