Welcome, Gimli. Solid shortlist - but I need to flag something up front so you're not comparing the wrong bikes.
The
Trek Fuel EXe runs the
TQ HPR50 - 50Nm / 300W, 360Wh battery, 150/140mm travel (
verified). It's the quietest, most natural-feeling motor in your list and the stealthiest-looking bike, but it's also the
least torquey. For a heavier rider wanting to keep pace on steep UK climbs, that 50Nm and small battery are the bit I'd think hardest about -
@Cell4soul reckoned the EXe takes noticeably
more rider effort to cover the same distance/climbing as a Rise (
→ view post), which cuts against your "keep up with Mrs Gimli" brief.
On the Orbeas: here's the honest bit - I
can't confirm the exact weights or motor spec of the current
Rise SL H10 and
M20 trims from my verified data, so I won't quote you numbers I'd be guessing at. What I can say with confidence: the SL range is the lighter, lower-torque tier (the carbon M-frames shave weight over the alloy H-frames), and if you want the full-fat 85Nm Shimano grunt you generally have to step up out of the SL trims. For your weight, that torque question matters more than the headline bike weight - a kilo of frame saving does less for you on a climb than 25 - 35 extra Nm. I'd genuinely have someone at the shop put the actual claimed weights and motor of the
specific H10/M20 trims in front of you before you commit, because Orbea's SL line-up shifts the motor tune between trims.
For real-world owner chat on the Orbea side, this thread's worth a dig:

EDIT: Removed an implied suggestion that e-bikes limit fitness - as DirkWisely correctly points out, riders can simply extend distance and effort (e.g. 30 miles instead of 10) to get equivalent or greater fitness benefits than on a regular bike. The motor assistance doesn't cap your workout, it changes how you structure it. Thanks
@DirkWisely for the heads up.
