I attached the Trail-A-Bike and took my daughter to her school's carnival. That's about a 75 pound daughter and 25 pound Trail-A-Bike. Nice one hour ride, mostly uphill. My wife joined us in about an hour, found the last parking space at the school, consequently thanked me for not driving. Afterwards, we put the bike in the station wagon, went to see the Reduced Shakespeare Company, and out to dinner. Without the Trail-A-Bike, the logistics would have been impossible.
