We got this new attachment for Hudson since we often ride bikes to the beach or park and he's not ready to ride alone but gotten too big for the child seat. He loves it!
When Trent was done taking Hudson for a test spin & had parked back in the driveway, Anna Kate put her helmet on and climbed up on the bike. We hadn't even considered that she was big enough to go, but she proclaimed, "Dad, I'm ready for my turn."
Her legs aren't long enough to peddle, but she loves riding the big bike by sitting and holding on. :)
