I started my son on a wee-ride co-pilot; when he got frustrated with that (anything over 12mph he was just spinning instead of helping to pedal) I go a tandem.
I joined a tandem group on Facebook and put out my request with this nice picture of my boys and set up at the time.
I soon had a couple of people trying to sell me their old tandems; I found a guy who really wanted my family to have his tandem; so I bought it. I got a child stoker kit added to it and last summer my boys and I really enjoyed our bike!
Summer 2023 my youngest will be old enough to go some miles in the trailer. He's a little too young to be in it much this summer.
So this summer both pictures get combined! Tandem, trail-a-bike, trailer set up will be in full swing! 7 year old on tandem, 4 year old on trail-a bike, and two year old in trailer!
