I recently purchased a very nice Raleigh Sprite iE for my wife. It's our first e-bike and we were quickly impressed. Now all three of the rubber buttons on the Currie/TranzX DP27 control switch/display have failed making the bike inoperable. Is there a way to find a replacement? I have sent inquiries to the US TranzX distributor and a few other online sources with no replies. Is there a current switch display that has the same 5-pin female connector and would offer the same functionality? Any help would be much appreciated.
