What is the environmental impact of building an e-bike? When people ride an e-bike, what are they no longer doing? Is an e-bike worse for the planet than a regular bike? In this video I talk industry experts and consult the academic literature on the net impact of electric bikes. The result may surprise you!

Of course, this is going to make it infeasible for lots of people who are looking to replace their car with an ebike, because trips would take too long (this needs to be solved in other ways). But that's the thing with ebikes, they're not intended as a more environmentally friendly replacement for cars, they're intended as a more convenient replacement for regular bikes.

It is interesting that the electric motor of an e-bike has lower CO2 emissions than the rider, but I wouldn't worry about it too much because the rider needs exercise anyway. Better to get exercise while commuting than to ride a stationary bike or jog around in circles.

I'm in The Netherlands and so of course I have a regular bike I use for most trips. But I've actually used an electric bike for a while and the main drawback I found was having to carry the battery everywhere I go. The battery is expensive so can be taken out to avoid theft, but it's also heavy. A regular bike on the other hand I just put somewhere, lock it, and walk away. This is especially true for a 2-minute trip to a supermarket for example. They are quite fun to ride though! And they make trips seem a lot shorter than they actually are: a long 45-minute bike trip suddenly becomes an enjoyable 30-minute trip depending on how fast you go.

@_yonas 2 ай бұрын

Does your battery not have a lock? I wouldn't trust it to leave my bike outside overnight, as the battery only has a rather flimsy plastic clip to hold it in place which the lock holds onto, but for a quick trip to the supermarket and so on it seems safe enough.

@skyrideabc 2 ай бұрын

The way I've dealt with this is by building my own from a regular city bike, locking it up like a regular city bike, then just accepting there's a decent chance the battery will get stolen eventually. Because its a self build the batteries are much cheaper, I could replace it for about 300 euros and its much higher capacity than any of the ones that come with off-the-shelf ebikes. Its been a year and a half and lucky so far. If it got stolen tomorrow its probably still a net saving in money not spent on OV and extra trips I might not have otherwise gone on at all.

As for that weighty battery, I leave it at home when I don't need it, leaving me with basically a regular bike.

Where you live is likely pretty flat, though. The benefits of ebikes really kick in where it's hilly. Here in San Francisco, ebikes open up whole sections of the city that are essentially inaccessible for most people on a conventional bike. Even if your destination isn't in a hilly part of town, there are probably hills between where you're at and where you want to go in a town like this. With a conventional bike, you have to take a longer route around that obstruction. With an ebike, you can just fly straight over them. That advantage is worth having to lug a battery around in your backpack sometimes.

@Casual_Stroll 2 ай бұрын

Great video, only 1 thing, E-Bikes are only expensive if you're comparing them to a regular bike. If they're replacing a car, the math flips completely and they are, relatively speaking, dirt cheap. I bought a $6,500 E-bike that I used to go from a 2 car household to a 1 car household. 2 years later and I've spent a total of $50-60 on it for maintenance and repairs, and $25 of that because I hit a thumb tack in the road and had to get a tube replaced, and a total of maybe $10-15 a month for insurance. Idk how much electricity costs to charge the battery have been but it's pretty negligible, I didn't notice my energy bill change at all pre vs post E-bike. The total I've spent on the E-bike over 2 years is comparable to what a car costs in a few months between insurance, gas, and depreciation. And if more people in society would move away from cars we could save insane amounts of money on road infrastructure as well. So yea, if you're someone who's even mildly curious about getting around on an E-bike instead of a car, do it, it's better for your health, the planet's health, and your wallet's health.

It's mostly to infrastructure and government level decisions, not individual choices. I live in Poland, tried ditching a car, but other people in cars are crazy, riding on roads is too dangerous, riding on sidewalks is illegal and cycling infrastructure is almost non existent. Ended up with a broken wrist and two years not being able to ride a bike. Riding a bike is MORE DANGEROUS than riding a car if the infrastructure isn't already established. Yes, cycling is better for environment and for health ONLY IF everything is working alright. We have to advocate for better infrastructure and laws, but we also have to ditch wishful thinking and shifting responsibility to individual choices.

Funny enough, EVs are still better than ICEs even if you power them 100% from fossil fuels, the only one that compares is diesel because of how efficient diesel ICEs are. The only problem is that if you are powering them entirely through fossil fuels it may take most of the lifetime of the car for the savings to pay for the production emissions, but in countries powered mostly by clean sources it can be as short as 2 years.

@iivin4233 2 ай бұрын

Just tell them that while you can run an EV on coal or solar power, it's pretty hard to run a diesel engine on either. Hence EVs. The big problem with EVs in my experience is that people insist on fast charging. We do have big circuits available in most houses already that can be used for fast-er charging. Why your 30A drier or 50A oven or, heck, even your 20A bathroom circuit can't transfer between doing what it normally does and charging your EV is beyond me. But we do not need to fast charge everyone all the time. Our infrastructure in general functions according to 60 year old paradigms, and so do our brains. Other options like zoning reform and public transport would eliminate the need for car sized EVs entirely in many situations. So it shouldn't even be a matter of transitioning every last gas car and residence to lightening fast charging EVs.

The thing with EVs is that whether they are better than ICE really depends on how much you use them. If you drive 25,000 miles a year then the construction cost of the EV will quickly be overtaken by the environmental benefits of running off the grid - but if you only drive 2,500 miles a year then it's doubtful that the gains will outweigh the costs within the lifetime of the vehicle. Obviously as we move to more green energy generation and more battery recycling then there that threshold will get lower and lower over time. It's also hard to quantify the costs and benefits, because they are not always on the same axis - eg, the damage caused by lithium mining has some impacts, while the damage caused by fossil fuels has different impacts, so you need to determine some way to equate them, and that will inevitably a level of subjectivity.

While an E-bike is certainly more efficient than most forms of transport, I have a hard time agreeing with them being more efficient than normal bicycles. Sure, an electric motor is more efficient than a human at moving a bike, I think that kind of brushes over something big. People have to eat anyways, and I have never come across someone who eats significantly more because they commute by a traditional bike. So charging a battery is essentially extra energy being used on top of the energy that would've have been used anyways to produce food. Also from my perspective as a bike mechanic, beyond just the production of the motor and battery, it is also worth noting that e bikes tend to go through the consumable parts of a bike significantly quicker. Simply because of the additional power and speed available to an e bike, they go through chains, cassettes, tires, and brake pads much more quickly than one would on a traditional bike. Because of this, e bikes often need e bike specific components that use more material in order to make them more robust. That carbon impact needs to be considered too. E-bikes hey are also significantly heavier, so shipping them from the far east where most are produced, will also be more intensive. I definitely do not hate e-bikes and I definitely think they have a strong place in the market, but It just seems insane to me to argue that they are better for the environment than a normal bike. I mean I 100% agree that getting anyone on a bike is infinitely better than having them take most other forms of transport, but I also think that a significant portion of people who are considering buying an e-bike would be just fine on a normal bike. Government all over the world and at all levels should be promoting cycling, but I really dislike how much e-bikes are being pushed, when normal bikes are perfectly fine for most people, while being better for cities, safety, and the environment. In our shop, one of the most popular reasons for people buying e bikes is because they don't want to arrive to work sweaty. This group, for example, usually don't need an e bike, they just need to bring a change of clothes with them to work. That's an additional battery and motor that needs to be produced. Sure, if they would have otherwise driven, it would have been much worse, but if they went from a car to a normal bike, the planet would be better off than going from a car to an e bike.

Whether or not you notice it, you are burning calories by being on a bike. Either you're losing weight, or you're eating more food, but those calories are coming from somewhere. My watch's stats (which are definitely a bit inaccurate) suggest that for a 5k cycle I burned around 150 calories from the cycle itself, plus 35 calories from general life needs. Given the figure he quoted about the carbon footprint of a single steak (≈100kg_CO2/kg_steak), a 5km cycle ride powered entirely on steak would need (using the USDA's 271cal/100g stat) about 55.4g of food, or 5.58kg_CO2. Obviously you aren't 100% powered by steak, but it's a lot more believable how someone who eats a lot of meat would be less efficient than an ebike.

Couldn’t agree more. I think e-bikes have their place but as with anything, you need to question what kind of modal shift exactly they are achieving.

Well it's easy to work out. A human producing 250W on a bike is only 30% efficient, so they radiate 500W of energy as heat at the same time. Electric motors are more like 85% efficient. And the production (and consumption) of food has many losses in terms of energy, more than that produced by energy generation. I'm a cyclist (very much *non* ebike!), and I also use an electric scooter. It's very obvious to me that I actually use more energy (NOT including the extra food I eat after cycling) in the shower I take after cycling, than in the energy used in my electric scooter to get somewhere. So they are massively more energy saving.

Besides the fact that most people in say the U.S. could bicycle a good 30-50km per day without eating ANY more calories (they would just be thinner/healthier/save CO2 in the form of vastly reduced health care costs), when you do need to add a few extra calories to your diet to compensate for the travel, most people will add more of the things that have the very lowest greenhouse gas emissions. The amount of GHG emissions per food calorie varies by a factor of more than 100X. When you add an apple or a banana or a bit more oil to your diet to compensate for a bit more energy expended during that day, those are all things very much on the low end of that GHG emission spectrum. If you absolutely insist on eating every one of those extra calories as shrimp or beef, OK. Most people won't do that, though, simply because of the expense. I guess it is mildly interesting (and definitely clickbait) to get all wound up about which of two very good alternatives is 0.001% better than the other for some esoteric and very debatable reason. But it seems far more profitable to spend time comparing either of them to the massive gas-guzzling energy-wasting uses that form the vast bulk of global energy expenditure and GHG emissions.

I sold my mountain bike before Christmas 2023, as I’d only ridden it 20 miles in 2 years, it was just clutter in my flat. I’m physically disabled, and wanted a bike to increase my strength, and exercise more to reduce weight as that reduces pain. I bought a MiRider GB3 on the 8th March 2024, the weather has been atrocious up here in the North West, but I’ve still managed 4 rides totalling 20 miles in the last 3 weeks. I’m getting out more even in poor weather, and slowly I’m getting better. Today I went for a leisurely 2 miles down to Preston docks, and rode back up the killer Penwortham hill, when I got home, I decided I still had more in me, so did a further 3 miles circuit including the hill again. I can see me riding this little bike a lot, especially as it neatly fits in my car boot without removing seats. It’s the best bike over ever bought. I bought it through my company’s cycle2work scheme, and I’ve done the commute once already in pouring rain.

Hey, I worked on greenhouse gas Life Cycle Assessment (LCA) for electric cars over the summer. I'm not an expert, but I can chip in some information here. In general these analyses look at total lifecycle emissions: Total Emissions = Manufacturing emissions + Usage emissions - Emissions saved by recycling. Electric vehicles have less usage emissions (because the power grid is generally cleaner than petroleum). However, because of the battery they tend to have higher manufacturing emissions (which is why battery recycling is so important). There are a lot of potential pitfalls with lifetime carbon estimation. Keep in mind that the manufacturing emissions should include the emissions used to transport the goods throughout the supply chain. Additionally, there are a huge variety of different types of emissions which we need to normalize for the sake of comparison. For that reason we tend to use GHG100 or the equivalent carbon emissions after 100 years. However, there are a lot of assumptions in these models. What is the equivalent emissions of groundwater pollution? What is the offal fraction of metal stampings? How do you model the human cost of cobalt mining in the DRC? Depending on the models you use and how you run the numbers it's possible to get these models to say things that are not true. Because of this, you have to be careful about how you phrase your questions. These models are not crystal balls and cannot answer questions they were not designed to answer. In general you do a great job of presenting this information. However, you seem to have hit one pitfall with the comparison of normal biking and electric biking. This is a very contentious topic, and I don't think you realized the ethical minefield that you stumbled into. For example: "If humans produce carbon emissions and we want to reduce emissions, should we kill humans as a part of public policy?" The answer is obviously no, but when you blindly follow these data without looking at the broader picture you can come to these conclusions. Life Cycle Assessment is interesting because it falls at the boundary between hard science and ethics. It is absolutely possible to make mistakes on either side of that line. Just because an assessment is mathematically correct does not mean it is ethically correct.

I believe the inclusion of the calories into the calculation is relevant for ebikes since if you went from driving a car or taking a bus or a train to riding an ebike, you are going to use an additional amount of your own energy compared to riding on the other vehicles, which will make you lose weight in the long run if you don't change how much you eat alongside changing to an ebike. And thus to not continually lose weight, you'll have to eat a bit more. Also speaking anecdotally, when I started commuting on a bike/ebike, the amount of exercise I did outside of the commute was more or less the same as the amount of excerise I did before.

However, regular bikes have the advantage of not requiring a battery and making the person on it healthier, which I think outweighs the positives of e-bikes. Side note: I also believe that in any climate comparison, the emission of breathing should be ignored as it is something that can't be prevented. Of course the diet plays a role in climate change, but this should not be included in a comparison on transport.

@@freddyjl Right, I do agree and think the framing here feels dismissive of regular bikes, but I also think that this framing also can allow anyone concerned about the added complications of adding a battery and motor to a bicycle to feel less conflicted about using an ebike if they feel that a normal bike is not a great fit for their needs, seeing that it's not significantly worse than a regular bike by these measures. I think many people are already aware of the advantages of regular bikes over ebikes, but I do think that Simon could have emphasized that if you're able to and are fine with it, do definitely use a regular bike for its additional health benefits and it not needing to use costly materials like lithium. Side note: I actually only have a regular bike since I haven't felt like I needed my own ebike for my commutes and also because of the additional exercise, especially when I find it difficult to find time to do exercise outside of that.

Yup or maybe even supercapacitors? For cars their power density just won't cut it yet, but I could see some interesting use cases for ebikes there. They don't wear out nearly as fast during charge/discharge cycles and can take much higher currents. So at the cost of for example 30% of the normal range you get the option to fully charge it from 0 in a brief period (10-15 minutes?). Could even see some value in a hybrid system with some supercapacitor storage and a normal battery, instead of taking hours to fully charge a battery at a quick stop you could plug it in briefly letting the battery charge normally and the capacitor getting fully charged as it's parked outside a store you're visiting briefly for a few minutes. I guess it might be less valuable for personal ebikes but more useful for rideshare applications where you're encouraged/rewarded for putting them in a dock that charges them? The owners of more intensively used vehicles could value the reduced capacity loss from cycles as well.

Also, charging is an issue. At a time where cars are on pedestrian pavements, I would still keep Ebikes and especially scooters off pavements, completely. They are very intimidating.

Yeah, the C in NMC is Cobalt (Nickel, Manganese, Cobalt). I suspect he just mis-spoke, although electric cars don't all use 18650 cells either so maybe he's just mis-informed. Older e-bikes from the 1990's did use Ni-Cad (Nickel Cadmium) batteries though. There's no reason you couldn't use LiFePo4 (Lithium Iron Phosphate) and avoid the Cobalt that is still associated with the human abuses in the Democratic Republic of Congo.

An eBike changed my life. I live in a very hilly area and I have two small kids. Before I had an eBike we just had to drive everywhere as the thought of pulling two kids in a bike trailer up the hills was daunting at best. With the eBike, we can make small trips around town (to parks, to the store, just out for a ride) that we never ever would have attempted before. Hell, even if the kids don't come with, I can hookup the bike trailer and do the big grocery shopping trip without starting the car. I love it and recommend it for everyone.

While the resource extraction methods are absolutely problematic, I’d argue that the ethical issues with buying and using any other form of transport are as bad as for e-bikes (especially for anything fossil-fuel powered).

Remember that Cobalt (the one that has association with human rights abuse) is used for removing Sulphur from Petrol and Diesel. So if you have an issue with the ethics then using an e-bike is actually no different to using a car. You can also get batteries that contain no Cobalt and are actually safer than traditional e-bike batteries. (Lithium Iron Phosphate - LiFePo4) Plus not all Cobalt is extracted in the Democratic Republic of Congo by exploited workers. A lot comes from places like Australia and even the stuff from DRC can be traced to mines that are ethical in their treatment of workers, and that is being improved all the time.

@Sprosbold 2 ай бұрын

And you will continue to lose weight until your diet roughly catches up to your output. The fact that you lost weight means you went into your energy reserves because you were at a net caloric deficit. As you lose weight, your energy needs will drop *slightly* due to the reduction in energy needed to shift your mass around, but metabolically your needs will be similar and you will keep losing weight. Eventually your daily output is going to drop or your input is going to (slowly maybe, but still) rise to meet the new demands. Just because energy runs through a biological system, doesn't mean it's any less beholden to the 1st law of thermodynamics. Are bodies are very good at storing energy, these big buffers mean that you won't be able to measure or feel much different over short time intervals of a treatment. Over time, net effects become obvious.

Sure, an E-Bike has a positive effect in that regard to, but not as big and also in kind of a bad way as well. Less pedealed -> less emitions -> less health benefits.

If you want to get an ebike, go for it, but please don't get one where you don't have to pedal. Riding one on the highways would require it to be registered, insured, taxed (although the cost would be zero), have a numberplate, and you'd have to have an appropriate licence. You would also be prohibited from using designated cycle areas. If you don't satisfy these requirements, your bike could be seized and you could end up with a fine and points on your licence.

@@stealthxg5045 Unless you rode it on privite land with the owner's permission, you were breaking the law. Also, the maximum power-assisted speed of an ebike is 25 km/h, so it sounds like you bike might have gone quicker than this. This basically means your bike would have fallen in the same category as mopeds/scooters, so all the same rules would apply (licence, CBT, insurance, registration, etc...). I also doubt your claim that 'most' ebikes are like this. From my experience, most ebikes are UK highways legal. I'm an advocate for active transport, and we have to comply with the law. Mr Clark really should have done his due dilligence and checked all this out before uploading a video of himself committing various motoring offenses. I think it was a mistake to collaborate with Electro Heads as they're well known for not complying with highways laws.

@fghsgh 2 ай бұрын

That's why they need to be regulated, like they are in many EU countries. Motor can't go above 250 W, won't support you over 25 km/h (that's 15.5 mph), and no separate throttle, will only run if you're actually pedaling yourself. If it doesn't comply with that, it counts as a motorcycle where I live (which also has different classifications and various rules depending on type). Of course, this is going to make it infeasible for lots of people who are looking to replace their car with an ebike, because trips would take too long (this needs to be solved in other ways). But that's the thing with ebikes, they're not intended as a more environmentally friendly replacement for cars, they're intended as a more convenient replacement for regular bikes. And you may also go a bit faster because there's no way you're averaging 25 km/h on a bike on just leg power (especially uphill).

Bit silly that everyone everywhere misses the fact that if someone replaces cycling with a more carbon efficient mode of transport (say 100% assist electric bike), then they'll probably have to start exercising more. There is a bare minimum that one must eat and cycling/walking is often the way (at least for me) to actually use up those calories. If I got an ebike I would both emit carbon for the electricity to power it and then I'd have to expend the saved energy anyways through some form of exercise.

I'm looking to buy an e-bike for health reasons. Unfortunately we have a new government which is very car centric. It has stopped all new and proposed bike lanes and infrastructure, and all new and proposed pedestrian safety measures in favour of speeding up traffic, building new motorways, etc. The imperative of the new Minister of Transport is a reduction of any impedance in the travel of commercial trucking and private motor vehicles. They also removed low emission and EV subsidies. So riding a bike will remain a "take your life in your your own hands" option only.

My light E-bike has been a game changer for me, as it reduces strain and exhaustion, but still lets me work out. After 1/2 year I'm so much fitter again, and the car is only used an very bad days. The E-bike has also helped me ride with myuch stronger friends without completely blowing myself away. Battery manufacturing and lifetime is a valid ecological concern, but if e-bikes replace cars, it's more than worth it. Our town subsidizes cargo e-bikes, and many families are opting for one instead of a second car, which is awesome.
