I purchased a Currie 2014 E3 Dash a few months ago. After only a couple weeks, it started to lose power, then regain power while peddling, like someone was tapping the brakes. It gave an E6 error message. The dealer replaced the lower connection between the control or battery and hub motor. It still gave me the same problems, but no E6 error message. The dealer replaced the entire bike. The replacement worked fine for a few rides then, it too, started doing the same thing and gave an E6 error message. The dealer called tech support for Currie. They said to check the wire connections in the handlebar control panel. The dealer checked that and it is still doing it, but no more E6 error code. The dealer says he has sold several E3 Dash without similar problems. REI sells this same bike, so I checked with them. They say they have not experienced this problem before. I love the bike, but I am fed up with this persistent problem. I have taken it back to the dealer at least 6 or 8 times. I have told him I either want it fixed or another replacement. Anyone have any advice?
