Now my questions....
1. The bike feels wobbly, particularly at low speeds -- like it goes straight, but the front wheel is flopping back and forth much more tangibly than I'm used to. Is that normal? A bi-product of the tiny wheels maybe? Will I get used to it? It's very disconcerting. I feel like a kid just learning to ride a bike for the first time
I ride 305 16" wheels frequently. Just did 50km today on one such wheeled bike today. No, your wheel is wobbly cuz it's wobbly. Nothing to do with its size. Get it checked out.
