It's still so relevant 7.5 years later...dynamically delivered!

One of the best videos I have seen making the case for pedal assist bikes (E-Bikes) as a serious and viable form of transportation. It has a clever correlation of the energy efficiency of a rider and an E-bike as compared to other forms of transportation. Interestingly, a rider using solar energy for charging and practicing a "locavore" lifestyle is more efficient than a passenger on a train. The health benefits alone (especial mental health, weight control and regular exercise) seals the deal. Two thumbs up and double ding.

The health benefits of regular cycling far outweigh those of using an electric bike, and solar panels require far more energy in their manufacture and delivery than a regular bike does. Electric bikes are a false economy.

I use an eBike in Washington DC to commute 25 mile round trip, 4 days per week. Saves $8.50/day and is 20 min. faster than the Metro. The exercise improves my attitude at the office and my weight and fitness level at 46 is exceptional. The assist helps me in city traffic or when I am hauling my 35 pound toddler around to various playgrounds. I don't think of the eBike as a replacement for my regular bicycle, but as a viable alternative to the metro or driving our car.

The energy cost of manufacturing the solar panel is significant and must be added back in. He also doesn't include the energy costs to manufacture the bike battery which are high as well. Without seeing the assumptions and details we can't evaluate. Many don't want to share those details because it destroys the narrative.

Excellent video, except for one thing, $5000 for an e-bike is way too much. It needs to be about $2000 for a basic model to $3000 for a long tail cargo bike. Also, a new battery, after 1000 charges, cost about $500. So, each charge is only $0.15 for electricity, bit also another $0.50 for the battery, for a total of $0.65 per charge.

I agree with you about efficiency. What I miss is the factor of Money and "total cost ownership" of e-bikes, since a bike with batteries has higher replacement costs than a pedaling bike.

He's talking about LOCALLY grown food. In otherwords, the food you are eating now, comes from 100's or thousands of miles away, burning up tons of fossil fuel to get it to you, which means your equivalent MPG that he has calculated for you, is far worse with food grown far away, than food grown locally. There is already a HUGE push in America for locally grown food, because it is healthier, many times uses a less toxic pesticides, or fully organic, and local grown and sourced farm produce or meat is in VERY high demand. This is not coincidental being in parallel with the explosive growth of ebike use, that is worldwide, and not just in Europe, or China, or now just emerging in the US. More than half of the US citizenry is morbidly obese. Not just overweight. Its morally reprehensible. People need to get off their hind ends, and get moving. Being in a car is just about SITTING. You are sedentary, and you are gaining weight. you are eating FOOD in your car, and its probably from Wendy's McD's, or far worse. Its fried, and fattening. and processed. So Americans are basically whittling their lives away being in cars. Or sitting at home in front of their PC. They are mostly weak, out of shape, and as they get older, their health costs to them and society goes through the roof. Its just not possible for America to sustain this unhealthy living. They can certainly try though, and die young doing it.

I am retired, age 70. In the 1890s wealthy people could afford to move out of cities, using interurban trolley cars, and live in secluded rural enclaves. This since has consistently been the goal of many Americans, and cars have made it possible for far more of us. Currently, and into the future, new jobs will be created in low-density ruralesque places, and given their productivity, the new workplaces will not employ many people, and better paid specialists will move about a circle enclosing a thousand square miles. This means mass commuting will be less frequent in the future. Because of harsh political and other realities in the US, it is not possible to Amsterdamize US cities. By the way, many areas in the US have harsh winters and summers--electric bikes are not practical for over half the year. As regards commuting, I planned routes for my car that used the least populated rural roads, and seldom met with traffic jams. However, all of this is pointless discussion. Energy prices will soon collapse, and we shall have flying cars that are quiet. Everything will change.

I don't buy the mpg conversion for a bicycle. I ride 300km a week. I don't eat the equivalent of 2/3 of a gallon of gasoline over and above a "normal" diet. You can do all the calculations you want, but riding my bike costs zero in fuel. And that's not even taking into account the health benefits of riding my bike, with only my legs powering it.

I'm not saying it's 100% accurate, but at least he's accounting for it in his calculation instead of dismissing it like most do.

The idea that a cyclist is not as efficient because his food has to be delivered is complete nonsense. A bicycle is far more efficient than any other mode of personal transport because everyone has to eat anyway, and a bike keeps you fit when other forms of transport (except walking) do not.

I guess pepole forget where materials and the processes come from too make stuff Add in the inefficiency of a pedal bike,,, ebike and human the numbers work out too 3 too 4 mpg of the life time of bike and human. Oh well, at least you tried to stress the point but the majority of humans won't fall for fake numbers. just saying is all. And by the way, a rail system carbon foot print w/ replacement of trains, rail line "the whole grid " , and energy too run it is 2 to 3 mpg. Pepole won't follow fake number's of a unrealistic fantasy.
