Electra bikes have to be bought from a dealer . I ordered it through REI , an Electra dealer . There's 4-5 of them in my state , all on the north side of Atlanta . All about an hour or more away . So when I picked up my bike , I checked out the accessories . They carried very little in the Electra line .
So , I did the next best thing , IMO , I ordered directly from the manufacturer .
I don't think the seat post clamp is removable on the Cruiser 1 . I'll check again in the morning .
I don't have a problem with the quality of the rack. It's the other items I ordered that were junk . The "retro" pedals that look like rubber in the picture , that are actually hard plastic and the plastic framed bottle cage holder that strips out before the screws get tight enough to get the slack out of the bracket .
Bottom line , I thought if I bought acessories from a manufacturer that is considered to be step above , they would be better than what I could get from the local Wally World . It seems one has to sort through it all. You can't just go by name . Kirby
