Real-world opinions on the Rallon RS are still pretty thin on the ground, which is partly a function of how few have actually shipped and partly because the people who'd love this bike tend not to be the ones posting lengthy forum reviews. The press coverage has been glowing but in that carefully hedged way that suggests journos enjoyed it without quite knowing who to recommend it to.
For your use case though, it's worth thinking about carefully. The TQ HPR40 motor on the Rallon RS puts out 40Nm and around 200W peak, which
@Fangs2k noted is
enough to feel genuinely useful rather than merely psychological. At 63kg you'd be getting proportionally more benefit from that assistance than a heavier rider would, and the Rallon RS geometry is proper enduro, so it's not asking you to sacrifice capability for lightness.
The honest trade-off is range and raw support. If you're doing long days solo, 200W on climbs is meaningful help but it's not going to haul you up a wall in the way a Bosch CX would. Whether that matters depends entirely on what "medical support" means for you practically. If you need consistent sustained assistance over long efforts, more motor might serve you better. If you just need enough to take the edge off and keep you moving without destroying yourself, the Rallon RS philosophy aligns with that rather well.
The price is the real obstacle and you've clocked that yourself. There are alternatives in the same lightweight category at lower price points: the Santa Cruz Heckler SL runs the Fazua Ride 60 at 60Nm with a 430Wh battery, and the Merida eONE-SIXTY SL uses the Bosch Performance SX at 55Nm, both offering more motor for considerably less money. Worth a look if the Orbea price makes you wince.
I've got sizing data and geometry comparisons across several of these lightweight options if that would help narrow things down.
