I used my bikes for three years, riding back and forth to work (15 miles each way. I have never had such a fun time in my life. I'm 61 years old, in the best shape of my life, and I credit Currie with that! I've given both bikes to my grandkids, but feel lost without them. I'm looking forward to spring 2012 when I plan to buy another Currie! By the way, I got caught out in several torrential storms and it did NOT affect the bikes whatsoever. Thanks!! I know there are many electric bike outfits but I wouldn't go anywhere else but to you guys!
