I have the 2018 Monterra 2, my original intention was for trail work, recovery and self shuttles. What surprised me is what a blast to ride and how capable it is overall. I have a long DH and Enduro racing history, this bike improved my turning exponentially the weight and geometry,short rear is dead on and the 27.5 certainly helps but overall the confidence of how planted it is crossed over to my analog 29'ers. I take it out with my riding buddies on occasion to see what it's capable of and even though they are all on 150-160mm analog bikes I have no difficulties keeping up in the steeps, flow lines and jump lines. The Monterra is also a very capable jumper to only the suspension was holding it back some.I already installed a DVO Jade and have a RS 150mm Lyrik ready to install to give it more life. I believe 27.5 is a sweet spot for ebikes with quicker steering and lower BB helps with the weight. I'm open to 29er but would need ride time on one to compare.
