Oh thanks Browneye, senility popping in to visit. I guess I am a bit frustrated because I took bike in and techs did not address. Overall, the bike is a dream. Prior to purchasing, I had clocked thousands of kms on various bikes over the years. I also mentioned earlier I live on Vancouver Island where you do not peddle far before encountering another hill. The ups not the downs were beginning to take some of the fun out of my daily routine. When I test drove my first ebike I felt transformed. The ease with which I was able to ascend hills that formally daunted me was astounding. The Giant Explorer, mainly due to its ergonomics, fit and finish ended up to be my choice. I have no regrets after 1800 kms. The issues I described, now apparently for the second time are not major. I am slightly disappointed in the shop because the issues were not rectified, but I shall persist. I now recall telling you I am hesitant to fiddle with the derailleur. It why the techs are there and for the cash Iaid out for this marvellous bike, I expect them to make it right and I am quite certain they will. All in all, this bike does it for me and will carry me into my 80's very shortly.
