@IWantABike I'm in the hunt for my first ebike for commuting and since you mentioned the Surface 604 Rook you may want to consider the
Voltbike Elegant for $1299, which looks nearly identical. Court Rye with EBR did a
recent review on the Elegant, and though Court criticizes Voltbike's selection of entry level components from Shimano and Tektro, if you watch the video long enough into the actual test ride he becomes very impressed with the bike's performance. I've even asked Voltbike riders if they've had issues with these components and they've said, "no."
Like you, I was also considering the CrossCurrent S, but after speaking with a local ebike dealer here in Honolulu a few days ago I decided to move it further down my short list. He told me that he's experienced long delays in getting parts from them and communication has been poor. Being on an island out in the Pacific, and depending on my bike for commuting, I can't be waiting and wondering when a replacement part is coming. His experience may be isolated, but I take it into consideration nonetheless. As for the performance or quality of the bikes from JuicedBikes, he had nothing negative to say. The CrossCurrent S is definitely a feature-rich bike with a great look.
If you have any questions about the Elegant or anything else at Voltbikes, George Krastev is extremely prompt in responding. As far as I know, they only sell online although I think you can pick one up in person if you're near the distribution center in Burnaby, Canada or Blaine, WA. Otherwise, shipping is $70. Good luck!
