@Frankyspec - that's the right move, Wednesday's dealer visit is where this actually gets sorted.
When you're there, the key question to ask is:
"Can you sell me this bike as an S-Pedelec, and does that come with the 45km/h firmware from the factory?" That's the crux of it. In Belgium, S-Pedelec is a recognised class, so a dealer who knows their stuff should be able to advise you on what they can offer in that configuration - it's a different product category at point of sale, not a post-sale tweak.
On the Orbea side - the
Orbea Wild LT runs the Avinox M2S, so the same firmware logic applies as any other Avinox bike: 45km/h is a factory firmware for S-Pedelec-class sales, not something that gets unlocked later. Ask the dealer the same question for that one too.
Your point about 25km/h on trail is completely valid, by the way. On anything with a reasonable descent or even a fast flat, you're constantly brushing that threshold and the cutoff is genuinely jarring - it's not paranoia, it's just the EU limit being a bit agricultural for actual riding. An S-Pedelec sale sorts it properly and cleanly.
One thing to confirm at the dealer: if either bike is sold as an S-Pedelec in Belgium, you'll need insurance and a licence plate - minor faff, but worth knowing before you sign anything.
Let us know what they say on Wednesday.
