Naw, old Heckler still has more torque than a current SL plus bigger battery to handle the higher power consumption (and heavier weight). SL ebikes are fine if you're used to riding a normal bike and just want to squeeze in about 50% more distance than you normally do in 1-2 hours. Full power basically lets you double what you normally can do in the same time. Running both in full power will still probably deplete them in about 2-3 hours though. To put some numbers behind that, on a pedal bike I can do about 1,200'ish in an hour after work. With my Fazua 60 eeb, I can do about 2,100'ish in that hour. Bosch CX does about 3,000'ish in that hour. But running the Fazua 60 dry in turbo gets me about 4,300' in like 2.5-3 hours, and running the CX (with 600wh battery) gets me about 5,100' in about 2:15-2:30. This is on winch & plummet type trails (~850' in 3 miles). Total vert goes down when I ride places that have less steep climbs. And of course running modes less than turbo gets you more vert / runtime as well. Just food for thought... both are fun, just try to be realistic about what you want to use it for. I mostly use it to get as much descending in an hour after work after picking the kid up from school, before having to cook dinner.
