This 10-inch center fin includes a thumb screw and square washer.
I’m enjoying riding my Sedona 48. A recommendation for the next production is to make the front frame rod and the seat farther apart. When I stop and try to stand straddling the bike I don’t have any room. (And I’m not a big girl).
The trike was easy to assemble comfort I give 8 out of 10. The only problem was the derailure. I could not get it to shift into lowest gear and it makes noise when peddling. I will need for take it to bike shop to have it tuned. Other than that I am very pleased with product🤠
