Hi all! I will boast about my new Trek Powerfly 5 and post pics of it but right now I need your help and guidance by recommending a model of ebike for my husband who is 64 years of age, 6'5" and 240lbs. He rides a regular road bike but he has bad knees and wants an e-bike that will do the following: 1. have enough power to get him up hills, 2. potentially wants a hybrid that will do some easy mountain trails and also be a touring bike that he can buzz around the town or on a paved bike path. We have done a ton of research and we are at a standstill as to what bike to buy. His budget is around $5,000. I feel like the Powerfly is geared much more to mountain trails and much less to normal bike paths but I do realize it can do both. Can anyone throw out any questions or ideas for us? Much appreciated and I'm so excited to be a part of this community! I love my Trek e-bike, it's really fun!
