If at first you don't succeed...
til you do...Today my dealer said that his distributor is sending out a brand spanking new EZ3 to replace the one that I've had for almost two years....it's been a pain in the keester. Constant loud noises when putting the power to the pedals. So for the rest of you who are dealing with the same thing, I'd suggest that if your trike is still under warranty, demand that they give you a new one. For others who have given up on getting it fixed, keep on your dealer until he gives you satisfaction.
