if you do the math you can quickly prove to yourself that reduced inertia isn’t doing anything for you. you then either have to conclude that newtonian mechanics does not apply to bikes or perception can’t be trusted! if you do a blind experiment, where you don’t know the wheels under you, or a third party adds weights to the rim you can demonstrate this. be sure to use the same tires, at the same pressure, as tires…

> if you do the math you can quickly prove to yourself that reduced inertia isn’t doing anything for you. This is exactly what I was talking about. People like to assume that a simple math equation tells the whole story, while ignoring the fact that bikers do more than just exist as rigid attachments to a bike that travels in straight lines. I can do the math, but I can also swap wheels in a matter of minutes and fee…

So complaining that they don’t have the right mount point for a light when one doesn’t need to be mounted shows that the product either isn’t a good fit for you, or that you are grasping at straws. I think it is unlikely that a carefully designed bike like this missed something simple like that. Much more likely you are kissing something.

It’s a simple matter of geometry. The bar is too high for the light to effectively light the road.

Belt drives can be nice, but the reason they aren't as common is because they are incredibly expensive, unless you're getting a single speed which many, many people aren't going to want. I don't know if part of the reason they are so expensive is because they are a niche bike item, and bike stuff is already hideously overpriced, or if there is another reason.

Fair point, but this isn't a cheap bike, so maybe at least make the option available? I also am not certain on the exact reasons why internal gear hubs and belt drives are more expensive. I imagine manufacturing those hubs are more costly just by the nature of their design. It also used to be the case that you needed a specific frame built for a belt drive to run one, but they make breakable belts now so that's no lo…

E-bikes are perhaps the most misunderstood category of bike products right now. Traditional bikers have underestimated demand for e-bikes at every step of the way for one reason: Traditional biking has a massive selection bias effect that excludes anyone who isn’t in great physical shape. The deeper you are into cycling, the more homogenous your perception of what constitutes a biker. You’re not going to see average…

Decoupling transportation and exercise is valuable even if you are in shape.

> I'm an engineer and a biker. If you only look at the numbers or try to run simplistic calculations, it's easy to think that bikers are just deluding themselves. Bikes are all about diminishing returns. If you spend $500, you get a bike that's probably twice as good as a $250 department store bike. Spend $1000, and you get a bike that's half again as good as that $500 bike. Drop 2 large and you get a bike that's 25%…

> Bikes are all about diminishing returns. Pretty much everything is about diminishing returns though, so nothing special about bikes. For instance I can (and have) build a Miata race car for $5K to do good laptimes at the race track. Or I can spend over $100K on a car to go a handful seconds faster per lap.
