We recently bought an "e-bakfiets" and have been getting good use out of it. With fall weather it came time to assemble the Clarijs canopy we bought as an add-on. Clarijs is another Dutch company that makes various bike products. I decided to document the process since it's a bit involved in the current instructions leave something to be desired. I got some help from this article by Bicycle Belle out of Boston. And Urkai staff also provided some much needed instructions, especially since Clarijs recently changed the canopy to use a rigid centre pole but didn't update the instructions.
It's a bit intimidating to install since it involves making holes in the brand new box. You'll want to make sure you've marked where you're going to drill or screw and drape the canopy over so you can see if it'll fit. I found that if I could start over fresh I would have moved some of the holes I made but they do the job.
