I wrote my first message for return service on Saturday I believe.  They still have not written back.  It is just a standard return request for one of my unopened Radrover 5 bikes.  I haven't even touched the box because I wanted to test my wife's Radrover 5 first.  When I tested it, I thought it was a great bike, but I wanted more power for hills.  She is half the weight, so for her, the bike is almost TOO powerful. 

The whole reason I bought from Rad Power Bikes was if I had to make a return, I was secure in knowing they had top customer service (other sellers do not have such good customer service I was told). 

Have others had trouble getting standard return authorization for their bike if they have not even opened the box?  How many days behind are they with replies?  Last, how much is return shipping?
