Hi, my name is Eric. I want to thank Court for directing me to this forum. I have a Cube 29er that I would like to convert to an electrical bike. I have been looking for a while now and my mind is all over the place with the enormous amount of information out. I am hoping that perhaps with some help I can begin to narrow down the choices. Basically, I use my bike to carry a lot of weight, i.e I shop and have a two wheel tag a long for my 18 year old son. The combined weight with my son and myself and our bikes is about 380 lbs. I live in an area that does have hills but they aren't extreme, but it's enough to take everything I have to do it. My son loves his bike so much that he insists on the longest ride I can give him. Any advice as to what system would work best for us would be very much appreciated. Because of what I pull, my speeds are very moderate and I'd still like to get some exercise; so I wouldn't mind a pedal assisted system at all. Thank you in advance.
