Can't compare to a summit, but I will say this. Going from an Apex (shorty) to the Nytro (shorty) has been nothing but positive for me. The Nytro is better balanced and centralized, it feels 200 pounds lighter than my Apex. Ergos are better, a little colder to ride but the fun warms you up anyway. As for the motor, it seems the same if not better then the Apex, I'm not a top speed guy so the 100 mph is plenty.
