Thanks @Marty Backe. I have read many of your comments about the ACM as a good hill climber and I have been very tempted to purchase one just because of that. However, I do really like how the 22" wheel handles rougher terrain. I have tried a little rough terrain on my Ninebot E+ and the difference between the 16" and 22" wheels is like night and day for bumps/rocks/ruts and such. Maybe I just need to drink some more beer to gain a little front end weight to get things moving. I will probably get an ACM later this year. I'm waiting until Gotway gets all the bugs worked out.
I agree @KingSong69, I don't blame the wheel for my short comings. Interestingly enough, once the Monster is rolling it doesn't seem to have a problem. I just need to do my part to make sure I keep things moving and the Monster will roll/jump/bounce dare I say leap up and over. Looking forward to this summer.
