These engines will haul a lot of weight so don't be overly concerned with the total weight of the bike/rider.
Thanks for the reply.
Yes I am tall and shall I say "average weight for my 6'6 frame. I am 250 pounds, so I like and look "normal" on a beefy mountain bike. I know that most of the beefy frames are rather large and would wonder if the engine would be able to fit and work with a larger frame. I spoke with a dealer not to long ago and he told me that some bike engines have a hard time bolting to larger diameter frames. I was unaware that a 46-48 tooth sprocket could give more low end. With my weight I would need it. Thanks for your post!
