Angie,
I hope you don't have to wait until fall. Hopefully, Currie will get a replacement mailed out to you this week. In the meantime, can you scrounge a free one to use to ride until the new one from Currie gets to you? Does your local dump have an area where bicycles can be left or do you have a bicycle coop? If so, it might be worth while to check them out to see if you can get a seat post stem that will work, for free.
I'm looking forward to seeing a photo of your lovely new e-bike. Is the red paint metallic? Also, how dark is it, it's hard to tell from the photos I've seen. I'm also looking forward to your ride reports. I'm interested in what you think of the hub motor Currie is using on this model. I hope you're having a good holiday. Don't forget to get a good lock your bike, preferably, a small U-lock with good, heavy chain. FYI, if you don't want spend a fortune on panniers, but need a way to carry things, beg empty kitty litter pails off friends or family (if you don't own cats). You can spray paint them and then put J hooks on them. (You can find J hooks at most hardware stores.)
