Chances are if Rad operates like many on line sellers, they never actually have the bikes in their possession, but rather they are shipped from a 3rd party product distribution center staffed by temps who simply slap on a shipping label and hand it over to a carrier. I've been in the transportation business for 27 years, and I'm still amazed at the poor condition of some products before they're even unloaded from the shipping container from overseas.
I'm glad I will be picking up my Radwagon in person at their store, its not a guarantee it won't have some unforeseen issue, but any obvious issues, if any, will be resolved ahead of time.
