Here in India I see a few people cycling to work. A "few" (we have a LOT of people). I can't see adoption increase. I myself won't ride a cycle, because 1. There's way too much pollution on the roads. I'll die breathing that air 2. If I don't die breathing that air, some car or bus driver who doesn't give a shit about other people's lives and is on their phone while driving will hit me and perhaps kill me (or worse,…

Is 1 really all that different from driving in a car with the AC on? If I understand correctly, car filters typically only filter very large particles that would damage the engine.

Yeah, that's just ridiculous. You can cycle 20-25km/h without catching a breath if you are even in decent shape

Under good circumstances, yes. When you are cycling recreationally, you get to pick a nice day. But if you are cycling to work every day and deal with strong wind, elevation differences, maintaining 20-25 km/h is going to be tough. Sustaining 20-25 is easy for me on a calm day. But on steep roads or windy days it's definitely more in the 10-15 or 15-20 ballpark. (This is from experience. I am fit, cycle 22km every wo…

I used to cycle to work, 3 miles long. Half of it was a straight line along the road and the overground.

Doing 50 km/h in good shape and on flat ground. Keeping up with the overground and the cars.

Again we see that people will cycle if you give them cycling infrastructure.

>>> If the ride is so great and economics so favorable, why haven’t I seen more adoption here in US and Canada? The author's answers to this question focus solely on the bike technology itself. This is a common thread in a lot of discussions about cycling: If we only built the right bike, more people would ride. This is usually followed by a CAD rendering of the perfect bike, that looks like nobody would want to ride…

Indeed. The issue is the infrastructure.

Your also not exerting yourself and breathing as much though, I would think.

I mean just to look at one part of the world, but which many of us will understand, look at somewhere like San Mateo, the sub-urban area halfway between San Francisco and San Jose in Silicon Valley. Imagine living in a house with a garage somewhere like Foster City. https://www.google.co.uk/maps/@37.5466469,-122.2920167,13z?h... A family could get all around this area very nicely on an electric bike. Maybe you bike t…

(1) Having a town house with some wall socket at the entry or a garage and (2) not trying to get into a big city centre might be a use case, yes. Thanks for elaborating your example but I don't think that this use case is strong or ubiquitous enough (maybe in SF) to lead e-bikes to mass adoption. I still think the concept of an e-bike, in particular the charging, is super flawed. If the battery is removable you can c…

If the battery is removable, it will be stolen.

This. For the $1500 the author spent, he could have bought a decent bike instead of strapping a motor on a $200 piece of cast-iron junk. Plus, a 1000-watt motor is ridiculous: that's the kind of power generated by a pro sprinter, and over twice what a pro climber generates on average. A 100-watt boost would be enough of an advantage to make most hills easy, and would probably weigh and cost far less.

I don't think you have tried out an eBike before, 1000W is just about enough to make most inclines easy. If I drop my BLDC controller down to 250W it makes things rather difficult. Remember you are carrying around the extra weight of a battery pack and motor.

Perhaps if the rider is really heavy or untrained. :p I have a 500w motor and almost never have to use more than about 4/5 of the maximum throttle.

Is 1 really all that different from driving in a car with the AC on? If I understand correctly, car filters typically only filter very large particles that would damage the engine.

Engine air and cabin air are two separate intake paths.

The cabin air in modern cars is highly filtered.

" Most dust filters will stop 100 percent of all particles that are 3 microns or larger in size, and 95 to 99 percent of particles 1 to 3 microns in size. The combination dust and odor filters have a layer of activated charcoal or baking soda to absorb odors and air pollutants. Some of these filters may even be lightly scented to enhance the driving experience."

So yes. Being in a car with AC on is much better.

For most commutes the car would still win even if the air inside was the same as the air outside, because the car would be faster so you would have less total exposure.

As far as car interior air goes, I've noticed that when I walk to a nearby market during times when there is a fair amount of traffic I can really notice the smell from the cars, but when I myself am driving on that same road in similar traffic I cannot smell it.

My guess is that the rate of exchange of air between the car and outside is low enough that at least for short trips (a few miles, say) it mostly remains air that was from my neighborhood, which is half a mile away from any heavy traffic road.

Note: this is without using the AC.

I've read about motorized doping in bike races, with motors hidden inside the gearing, I wonder whether anyone's thought about this sort of thing for consumer bikes, and what sort of benefit you could get for, say, 1kg or half a kg of extra weight. E-bikes at the moment seem to have reconciled themselves to being twice the weight of ordinary bikes.

Have you seen this: https://budnitzbicycles.com/bicycles/view/titanium-ebike I think it’s the closest you’ll find to a bike the looks and operates almost identically to a traditional bike. No wires, no display, excellent weight, etc. Obviously the price is out of control, but still the right idea I think.

Is it really that bad if you could use it as your car?
