Here's a video from Wed or Thurs last week showing Ali on her bicycle. I tried to take some videos of her bicycling over the weekend as we rode a lot. She can ride forever. This is funny as she runs out of energy more when she is walking then when she is riding her bike. She loves her training wheels and has no desire to try and ride a 2 wheeler. I think this large bike would be hard to learn on as it's quite tall...
PS I think it's funny that Mia always chooses to wear her ski helmet rather than her bicycle helmet. Maybe she feels more secure in it.
