These photos are from Dunn Mountain ride, on out skirts of Nelson (NZ). The climb to summit is 14km up old railway line starting in Nelson suburb and ending at 900m in middle of mountains. The railway was built in 1890 to haul copper ore down from mountain top mine, horses towed wagons up and brave brakemen rode full wagons down.
The track goes over a pass and back down a MTB track to town water supply dam.
WARNING. Go well prepared this is a back country ride, not loop around local bike park even though it is on edge of town.
I did climb in eco and only use 30-40% of 500whr battery.

Track up, gets rougher than this later.
