I am pondering getting one for DS too, so I've been asking my friends about them. One of my friends has a similar product, but not a smart trike, and her son is about 3, so he's up to 'trike' stage- she says it can be a problem because its quite heavy, so he doesn't really have the strength to peddle it himself, so he doesn't like it much. I was surprised because it looked quite lightweight. Now I'm concerned about the smart trike and whether it would have the same problem- it actually looks like it would weigh MORE then the one she had.

Does anyone who have the smart trike have a child actually using it as a trike yet?
