Beautiful bike, but very disappointed to see a standard drivetrain. For a commuter I'm only interested in one with a belt drive and internal gearing. I'm not sure why these drivetrains are not becoming more common, especially for commuters.

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.

They are not expensive, lots of sub €500 city bikes have them them.

Two stroke mopeds are not new but I do not see them on bike paths. I do see them in the road. e-bikes that comply with the existing laws have similar capabilities to mopeds yet people ride them on bike paths. Another dimension of this phenomenon is electric cars. Teslas are somehow synonymous with "self-driving" even though they could have the same capabilities with gas motors. Somehow electric motors are translating…

No. Here are some statistics from the UK in 2018 because they’re the first Google result. Cycling is wonderful and is a net benefit to communities. Trying to claim there are no injuries caused to pedestrians by cyclists is just silly.

——————

Figures published by the Department for Transport (DfT) show that 531 people were involved in collisions with cyclists in 2017, up by 15 per cent in 12 months. The accident rate was higher than at any time since at least 2013 when the statistics were first published. More than 120 pedestrians were seriously hurt in collisions with bikes last year and three were killed, the figures show.

If there are pedestrians it’s a sidewalk, not a bike path, and a bike should not be on it at all unless the rider has dismounted.

This is ignorant. My local bike path is combined and separated and alternates between the two. There's also a bike lane in the road. There's also the practical fact that people walk in bike lanes anyway. Riding a motorcycle in that environment is going to increase risk.

Spaces where bicycles have right of way and spaces where bicycles are permitted to tread gingerly around other, higher-priority users are completely different things. Calling such a pedestrian path a bike path is like calling a bus lane or a truck loading zone with sharrows in it a bike lane.

I live in the Bay Area on the peninsula - I could easily name ten coworkers that have carbon bikes and usually more than one. They also often commute on them. They’re expensive, but the market exists (at least here). Ride portola loop or old La Honda on any given day and you’ll probably pass 100k worth of bikes.

Those people aren't going to be riding an e-bike, and if they are they won't be riding one with flat handlebars.

At least one does, but yeah I’m not sure how much that audience intersects.

I’ve also seen fancy specialized brand bikes with internal motors that give out an extra 250w of power. I suspected they were for older people that want to keep up on rides.

Main thing I was pointing out was that carbon bikes aren’t just for super athletes, they’re common where I live.

I don't understand why you need to measure anything but instantaneous crank torque, speed, and (for completeness) pitch angle. Integrating power in vs acceleration out, the difference is loss. What am I missing? Does bad posture waste energy before it reaches the crank?

In an ideal world with zero friction, zero wind, constant air density and no other losses that would be true. There are a few outfits using this approach, so we are the outliers (being the only ones doing it via direct force measurement, for which we have the patent).

You’re ignoring reality. There is a dedicated bike path that I ride every day with painted bicycles on the path and a separate sidewalk next to it with grass between. There are always people walking on the bike path. This is even understandable with covid, people are trying to keep their distance.

There are also people on ebikes going faster than everyone, swerving between the bike path and the sidewalk.

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…

Great points. I just bought two eBikes in the last six months and I love them so much. One thing that I really hate though is how hard it is to change flat tires and dealing with the bike shops. I can't imagine an older person being able to change the tires on either of my eBikes. I swapped out one pair for a pair that is somewhat easier to work with but it can still take me 20 minutes to put on a new tube. The bike…

If you have a hub motor ebike, installing puncture resistant tyres are essential in my opinion. I also have had bad experiences with local bike shops, and the cost of replacing a normal tyre with puncture resistant ones is made up as soon as you roll over glass (very common on my commute). Battling to get the rear wheel off and back on correctly again on my rear hub motor bike isn’t something I want to do again!

So there are no cycling paths in your area.

That's completely irrelevant. Some cycling paths in my area are mixed pedestrian and cycle. Mostly they are mixed car and cycle. There are a handful of dedicated bike paths but those often have pedestrians on them anyway. Good luck changing that. The semantics of "bike path" are not interesting here. I ride my bike at around 8mph. I don't pass many conventional bicycles. I don't get passed by conventional cycles much…

I think we were raised in very different cycling cultures. I was taught to be embarrassed at much less than 15mph under my own power. Being lazy, I usually rode closer to 11-12 when alone, and the only slower bikes I encountered were small children. Many athletic cyclists zoomed by at 20-25.

I was also taught to assert my right of way when I have it, and be deferential when I don’t. So the designation of the path does matter.
