I just got my bakfiets from MyDutchBike and the first order of business was to install hooks for an infant car seat. Inspired by these pictures of a solution, I headed off to the hardware store.
Here are the parts I ended up using - eye bolts, larger washers, and locking nuts.
The right side was easy and just bolted in place. Here's a picture of the bottom:
I had hoped to come up with a method that didn't involve drilling any holes in the bucket, but the kickstand magnet was in the way on the left, so I ended up drilling one hole for the left side.
All finished with both eye bolts attached.
And the car seat hooked in.
I added some old towels to cushion the ride a little.
I biked Silas to daycare today and he loved it!
(Here is how we used a bobike mini to transition to the bench once he outgrew the infant carseat)
