> A double chainring setup likely offers smaller gaps between gears but likely a comparable overall range from lowest to highest. This isn't true. This bike is using a 40 gear crank in the front with an 11-40 cassette in the back. That puts the gear ratio at 1.0 on the low end and 3.64 on the high end. The corresponding Shimano GRX setup with a double chainring would be a 46-30 in the front and a 11-34 in the back. This gives a 0.88 ratio on the low end and 4.18 on the high end, which is actually quite a big difference. One could argue that the difference in gear ratio on the low end isn't a big deal because this bike has pedal assist, but the difference on the high end is quite noticeable.

No one (basically) is going to care about the difference between a 46/11 and a 40/11 when the assist drops out at 25kph. If anything, you’re much more likely to be able to use the 40/11. At the other end, the assist is going to cover a lot of gearing, and it’s going to make the gaps in a 1x setup a lot less important. (FWIW, I ride a 1x42/11-42 and a 2x 50/34-11/32. And a triple on the tandem, and I lived with a cx geared 1x 39-12/28 for a few years. High gears are drastically overrated unless you’re racing)

  I definitely agree that high gears are overrated except for racing, but when the bike markets itself as a lightweight semi-aero bike, isn't the point to go fast? If you're not going faster than 25kph, then why are you need deeper rimmed carbon wheels?

    The 25kph cutoff is the legal limit for this category of ebike in the EU, 20MPH in the US. I think some of the price of the carbon comes out of the marketing budget. In a way, the difference between a 4k ebike with cheaper looking parts vs a 4.5k bike with "premium" parts comes down on the side of spending the money. I'd estimate that bike would sell for ~2k without the electrics. It's nice, but it's not super speccd. High end carbon rims are expensive, but they're not _that_ expensive compared to aftermarket aluminum rims. Niceish rims are basically 80-100 now. Carbon is probably 150 or so. (That's retailish, but not MSRP, what I could get them for, not what a bike co could get them for wholesale) OTOH, it's lighter than my gravel/commuter, which doesn't even have electrics, so there's that. But I'd need rack/panniers for the commute, and I'd have range worries there. What I'd like to see is a lightweight system that adds ~100W to my output for ~ 4hours. Something that's not painfully heavy if it's off, but makes the last hour of the commute better. (I do 2hrs each way when I do it.)
