We bought to Core-5s recently - blue and grey. They were shipped when indicated during the ordering process and arrived via fedex in a couple of days. We had a velotooler put the bixes together. Took the tech 45mins for one bike and the other took a bit longer but were riding within a couple. We have put in 100+ miles each and are loving the bikes. Very sturdy, a comfortable ride, and having both an accelerator and pedal assist are really nice. We have had a few questions and the support over email from Ride1up has been outstanding - super helpful and polite. We looked around a lot before pulling the trigger on Ride1Up and could have been happier with our decision. I usually don't write reviews but this one I felt is something I must.
