Sorry you are one of the many who are experiencing rear axel bearing problems. If your trike is still within 1-year Lectric will indeed send you a brand new trike in exchange for yours. That said I had two trikes fail within the first 40 miles. In my case I caught it early enough that I was able to make repairs to both without axel damage. The way I figured it if I got 2 more trikes then I would have to deal with the same problems all over again. Besides after changing out the bearings on the 1st trike and learning the secrets the second one was much easier, hey maybe I should write a e-book for a e-bike HA! As for the rear fenders another call to Lectric may help as I had 4 new rear fenders within a week of my first call. whatever you decide good luck to you and yours, let me know if you have any questions.
