I'm female, 46, 5'2" and 115 lbs. I ride around Jackson, WY and southern Utah; will be adding Mammoth, Park City and Crested Butte this summer.
@huckster welcome aboard. This is actually a great matchup to compare because they're both lightweight eMTBs, but they approach the concept quite differently.
The numbers first. The Rise SL runs Shimano's EP801-RS motor at up to 85Nm with a 420Wh battery (expandable to 630Wh with Orbea's larger option, or 840Wh total with the 210Wh range extender bolted on). The Levo SL 2 uses Specialized's SL 1.2 motor at 50Nm with a 320Wh battery (480Wh max with the 160Wh range extender). So the Rise has 70% more torque and 31% more base battery capacity before you even look at the upgrade options.
At your weight though, here's the thing worth knowing: 50Nm is genuinely plenty for a 52kg rider. You're not going to be sitting there wishing the Levo SL had more grunt. Both motors will feel capable on the climbs you're describing. Where the difference really matters is range, and that's where the Rise pulls away convincingly. At 52kg in a sensible assist mode, you'd get roughly 1,200m of climbing from the Levo SL's 320Wh. The Rise with the 630Wh battery? Potentially 2,000m+. For long days in Jackson or Mammoth with big vert, that extra capacity removes any range anxiety entirely.
Geometry wise, for your height the Rise S (425mm reach, 600mm stack) or the Levo SL S1 (405mm reach, 609mm stack) are the options. The Rise is 20mm longer in reach but 9mm lower in stack, so it'll feel a touch more stretched out. The Levo SL is slightly slacker at 64.6 vs 65.5 degrees and has 150mm travel vs the Rise's 140mm, so it's a fraction more planted on rough descents. The mullet setup on the Levo SL (29/27.5) does help smaller riders get the back end moving more easily.
One thing to flag: the Rise's EP801-RS motor has two profiles, a 56Nm natural mode and the full 85Nm RS+ mode. If you fit the range extender, torque is limited and you can't access the full RS+ power. Not a dealbreaker given you probably won't need 85Nm at your weight, but worth knowing.
The Rise is also meaningfully lighter, around 16.3kg for the top spec M-LTD vs roughly 18-19kg for the Levo SL depending on build. At your weight that translates to a more playful, flickable ride feel. The Levo SL rides deeper in its travel and feels plusher, which is lovely, but at 52kg you might find the suspension harder to get dialled at very low air pressures.
Your instinct towards the Rise is well founded. More range, lighter, stronger motor (even if you won't need all of it), and the steeper seat angle (77.5 vs 75.8) puts lighter riders in a better pedalling position. The only real argument for the Levo SL is the mullet wheel setup, the extra 10mm travel, and whatever that discount is. If the discount is substantial enough to fund a range extender or a wheelset upgrade, it might swing things, but on pure merit for your riding and physique the Rise is the better match.
