With Spring weather here at last, Homeschooled Farm Girl (age almost 17) and I have been logging big miles on our bikes. We’re preparing for the Calvin’s Challenge 12-Hour race, approximately one month from now, and hoping to beat the 188.5 miles we managed to do last year.
The younger kids want to get in on the fun, but of course can’t keep up. The 13 year old is probably going to inherit HFG’s old Trek road bike; he’s taken it out a few times, and really likes it, even though he’s not in good enough shape to keep up with HFG (who got a new road bike over the winter). Little Brother (age 6) keeps begging to ride with us as well. What’s a dad to do?
The sixteen year old and I got out for 38+ miles early this afternoon. We thoroughly enjoyed the sunny, 50 degree March weather, especially given that most of our route was on quiet rural roads. Would a few more degrees have been nicer? Sure. But we had plenty enough clothing to be comfortable. I took my vintage Basso Gap road bike, as a fun change of pace, and was barely able to keep up HFG.
We got home, and then it was the boys’ turn to join us for an additional six miles. Big Brother is still getting the hang of his sister’s old road bike, so that’s plenty of miles for him for now. And as far as Little Brother goes … I don’t want to take him on too long of a ride too soon, and have him get discouraged. So, six miles is plenty for him as well.
How does a cyclist dad take a six-year-old on a six mile ride? In a such a way that the six-year-old can be a full participant, and not just a passenger?
Behold, our Co-Motion tandem bike:
I’ve zoomed in on the drivetrain, so you can get a better idea as to how it works. Each rider has a set of cranks. Mine (the “captain”), up front, are connected to the “stoker” cranks in the rear via a long chain on the left side of the bike. There is a regular set of chainrings and sprokets on the right side, just like any other bike would have.
If Big Brother were riding stoker, that would be the end of the story. However, Little Brother’s legs are way too short to reach the pedals at the bottom. That’s where the child conversion kit comes in. Notice that I’ve bolted an additional set of cranks to the tandem frame, just under the stoker’s seat. These are connected by the vertical chain to a second chainring on the lower left cranks.
This whole kit can be attached, or removed, in about five minutes. The upper cranks are held in place by four hex bolts. All I have to do is remove them, remove the cranks, and the vertical chain simply slips off. Add a set of pedals to the main cranks at the bottom, adjust the seat height, and we’re in business for a new stoker. (The second chainring just stays in place; it isn’t interfering with anything, so it doesn’t need to be removed.)
Did Little Brother enjoy his first ride today? Oh, yeah! He had an absolute blast, cranking his pedals, as we flew along country roads. Yes, the captain supplies a huge proportion of the power. But that’s okay. StoKid is giving it everything he can. Best of all, he doesn’t have to worry about keeping up with Dad. And he’s close enough to carry on a conversation.
Our speed was naturally slower than what HFG and I rode earlier in the afternoon. And that’s fine. I still got a plenty-good workout, pedaling this beast. I sure enjoyed the change of pace. And the enthusiastic waves we got from other little kids as we cruised past them. And, above all, the smiles my StoKid gave.
Here’s hoping we have many more in the months to come.
