Ride included several one mile climbs at 8 percent grade and one two mile pull. Last week I put 3.5 inch road tires on it, aired them to near max and rode almost 60 miles on half a battery charge.

Didn't much care for the ride quality or noise but liked power and range, especially the long climbs and into head winds. On the Sumo I aired the knobby tires up to max and rode it on road a bit. So I am sticking with my regular dual suspension mountain bike for trails. it's a lot of mass to try to get back under control when going fast in technical situations. Problems are there is not a lot of protection for vulnerable, expensive components and no shocks, of course. 4 inch tires grip like no other trail bike and you can ride up along the side of the trail to allow another biker to pass or even ride off trail if needed. It's lots of fun on moderate-easy trails especially up hill, of course. About two thirds on the road, remainder on moderate trails and gravel roads. Having said that the Sumo performs like any another pedelectric in that a number of factors come into play. I live in Western NC in the mountains around Asheville, am 65 y/o and in average physical condition, weigh less than 150 lbs.
