I wasn't caloried up enough to take a ride (literally only eaten 550 calories so far, just too much to do) today so the 11 year old son is on the tandem with dad. He didn't even need to lower the seat AND he fits into my shimano cycling shoes.
I'll have to get a photo of them when they get back.
My son is 5 feet tall, and 75 pounds. It will be better for the DH with him on the back instead of me, and my 170 pounds! I'm hoping they do well!
