Thanks for the response. I can buy another battery for my Rad Rover 5 but the Himiway bike (Zebra) has hdralic brakes, better motor, more torque, a battery range of 80 miles which is built into the frame in a much better design and is only $1499 right now. It seems like it's a no brainer and I am hoping that Rad knows that and a new model from Rad will be competitive.
