Considering I'm currently 126kg and i live in a mountainous terrain, I'm thinking about it a lot even if i don't want to! 😉

Constantly!! I weigh 206lbs… will never be able to keep up with those slimmer bikers or runners 😵‍💫, but I’ll keep trying for the stallions 🤣.

depends. weight on the bike: not even one second since aero beats weight pretty much everwhere. our highest hill is just 277m around here in north/central germany so even up there aero is more important. weight on the body a little but usually that isn't a game breaker. on the flat it matters little and the second or two for loosing a kg bodyweight doesn't matter if you don't race

was hoping for a test on a hill climb as well.. but still enjoyed this test.. next 20kg weighted tests, constant power comparing time difference, and constant speed up climb for power difference.. yes?

I think GCN should spend about 10% of any video discussing rider weight addressing risks and harms of eating disorders. Also, the opening statement of this video conflates weight and health --- something to avoid, as the relationship is likely more complicated than the time you're willing to give it. (After all, many *doctors* aren't willing to spend the time learning the science.)

Lost 15 kilos 10 to go.... Keep it up!!!

How often and far did you ride to get these results?

@@jayhoughton4174 eat less ride more 😉 . Today done 80k and eat my last meal at 5''

From 220 lb to 190 in three mouths. Goal is 185. I can tell the difference when riding.

I've lost 6.5 kilos with 20 to go. Well done on losing 30 kilos. My weight loss has plateaued which is very annoying as I am not losing any more at the moment. I am 55. I don't always ride to work everyday which is only 3 miles (4.8kms). I know I should do more even if I am up to 101 miles (161.6kms) at the weekend. My best overall average speed with stops is about 10mph (16kph). 12mph (19.2kph) ride speed average. I weighed myself and bike with all it's accessories and tools, food etc. Total combination weight of 18 stones, 252 pounds, 114.5 kilos 😮. Guess it's not just me that needs to lose some weight 🤣🤣

Well done

Awsum work mate 👍🚴

Good job. I was 114 kg 18 months ago. Dieting and 5000 miles cycling later I’m now 76 kg.

@@gdwlaw5549 thanks

@@tomrowe372 thanks mate.

Agreed...fitness has decreased a lot since I eliminated my weighted (also 8-10kg) commutes 5x a day

Perhaps I should try my work commute without full gear because honestly I don't really notice if I pack on 10-15kg extra or not. Though my fully loaded winter commute setup is like 160kg so few kgs extra is a smaller percentage increase compared to elite cyclists.

I'm targeting 70 kg for may body weight. So I load about 8-10 kg extra everytime I MTB to train myself to push that weight when I reach it especially on climbs.

I lost 45lbs and was riding 5 days a week commuting to work by bike. I went on a group ride on my road bike after riding over a hundred miles that week. I felt great and the sub 19lb bike versus close to 30lb really did make a difference. Now I just have get back on the bike and ride ..a lot. I found too many of the pounds I had lost. 😬

Or Houston!

What bike were you riding at 284lbs? Cudos to that frame.

I lost 30 percent body weight but osteoarthritis progression hid any benefits so I didn't improve at all .

I started in 2016 was 93kg….now at 82 kg and not getting lower…if i do i dont feel well. I do a heavy nuilding stuff reckon my bones are beefed up from 30+ years of graft. Still get good seggy times but long climbs kill me

Yes, please let us know when you reach your goal! I hope you enjoy the journey.

113 kg checking in, godspeed 🙏💪🙌👏👍

how is it going?

@@Jim-no6dq thnaks for asking! Two back injuries and a new family member has been keeping me off the bike. But down to 100kg (I know only 2kg) so still a work in progress. Managed to do my first gym session on Thursday after months away so. I'm excited for the future.

spot on.. ask them to add 40KG on a stomach belt :)

Yeah, but you get that extra force on the downward pedal stroke from your leg rebounding off your belly.

@@FlatSpinMan ha ha ha ha

is a round tummy more aero than a flat tummy?

@@xtrailz Absolutely. Also, we in the pro peloton don’t call it a “round tummy”! The proper terminology is an “aerodynamic ventral fairing”.

Maybe they should've adjusted the tire pressure to take that into account.

@@RichardMigneron but then they'd be changing multiple variables.

@@danielburges8176 So, regardless of rider weight, tire pressure should be considered a constant? A pressure correction would have made the test more accurate. Moreover, a 20kg difference would not only mean having extra weight on, a trained athlete would also have more muscle mass, not simply a 20kg beer belly.

@@kaloyanerusalimov the (popsci-esque) test is more about extrapolating the effects of body fat, gear or a heavier bike in just weight terms. Not strength training.

@@danielburges8176 Of course, but if you weighted more, wouldn't you adapt your tire pressure ? I think, that's what most people would do by default. I would never ride with same pressure if I had a big weight diff., therefore it would be closer to reality.

That would explain why I do better on up hills with a more upright riding position...lol

Would love to see a 100kg+ climb. But putting too much extra weight on a smaller rider will mess up their core muscles so it won't be even close to true (probably +20kg is already doing this).

Kids, adults always love to ignore cycling rules. Traffic laws are not for cyclists!

@@martinkent333 relevance, your honour? 😂

It is a much bigger penalty on climbs. Doing tests for weight on flats is the easiest test you could do with extra weight.

@@lkb3rd Kids, adult cyclists and car drivers rarely obey traffic laws. Nobs on two wheels and Nobs on 4 wheels!

Correct! But it's just GCN.

CDA is the bigger factor

@@cnay2983 cda has nothing to do with watts

You are going to feel so quick! And yes. For them IS all about optimizing the power/weight ratio.

...but they can stop and have a small chat while waiting for us at the top of any serious climb waiting for our hearts to explode. 😆

Wow, that's unimaginable for me. I live at north of Slovakia, and it's impossible to do 60km ride under 800 meters of elevation, my weekly rides are typically 60-80km with 1000-1200 meters of elevation.

That’s why this country is called Netherlands … 😂

@@bikemike1118 should be called "Flatlands" 😅

here in mizoram which is a part of india, if we rode 10 km we get at least 400m of elavation gain.😂😂

@@iancuk maybe theta are fla roadster but wh4n I was in Middelburg and was riding on heavy Batavus with 3 gears and wind onto my face I was not able to go faster than 7-10 kph....

Like I think I already responded this elsewhere: For accurate measurement, they should test this with the Milan velomobile, because it disqualifies the aero component in two ways: - It's more aerodynamic, so you'll see more of the difference the actual weight makes. - The weight won't have literally zero influence on aero, unless you block the air outtakes in the back of the bike. The only thing "wrong" in the measurement is that it's really hard to divide the weight over the front wheels and the rear wheel evenly, and keep it in that exact position.

@@4nz-nl But there is a correlation between weight and aero. A rider with wider shoulders is less aero. So the simulation is ok when the same light rider wears an un-aero vest.

@@hzunasdfgbciw Unless you don't fit inside, with the Milan the shoulders don't really matter. That's why I'm not remarkable on a road bike but really quick in the Milan: I'm tall and strong, but not so aero :)

Yeah my motorised bike needs 400-500 watts to hold that speed, although it is a flat bar Scott Voltage MX3 on 35mm tyres and I am wearing a coat and jeans and sticking up at a 45 degree angle that makes all the difference. Also that is power INPUT so before efficiency losses in the motor.

@@Jay-yr9bj Not anymore actually - the sentiment (and the science) nowadays say that lower pressures are actually faster. Especially with the advent of tubeless tyres on road bikes, most pros are now riding lower pressures.

@@Jay-yr9bj 3 teams in the TDF used tubeless. Apart from that, agreed

There are other ways to alter carrying capacity. I use one size larger tyres than my wife on the rear. To compensate for being a little heavier. This does mitigate the mass so in rolling downhill on a mild grade we both end up rolling at almost identical speeds. Similarly although I have slightly more mass I correspondingly have slightly more power so on a sustained climb we go at about the same speed. Before I decided to go up one size my tyre wore substantially faster than hers and now the two tyres get replaced at the same time.

@@willhoffert3744 however the pro rider wasn't stronger, he was the same in both runs with just the extra weight?

Depends, if the muscles are in the legs, yes. Muscles in chest, shoulders or tricep wouldn't do you any good.

@@williamko4751 👍💪

@@willhoffert3744 Agreed. Maybe if you were talking about a body builder who lost 20kg then muscle loss might be a thing but here we’re mostly talking about normal people who have taken up cycling after being inactive so the weight loss is mostly going to be fat, so non-functional weight. It might even be that someone who loses 20kg through being active actually gains some muscle rather than loses it. It could be they’ve lost 22kg of dead weight and put a couple of kilos of muscle on.

@@MattSwain1 still not quite. I was a body builder. Started riding exclusively. Lost a ton of weight (215lbs to 170) and increased power on the bike significantly.

60kg. Wow, that is staggering. Congratulations! That's amazing, two of you! Could I ask, at what time did you notice that your power also dropped, there must come a point perhaps when weight loss isn't made up by the w/kg gain, if you can't then produce the power, is that right? Or do you think your body settles at its own equilibrium and it'll be whatever it'll be!

@@jgogl9791 I never really noticed a drop in power or performance TBH only a constant improvement. But my bikes, equipment and general heath/fitness all improved/got upgraded over that time as well, so if it did happen I think it got lost in everything else if you know what I mean.

@@jgogl9791 Just to add as it might be related. When I started riding my cadence was around 60 (very much a grinder) this got slowly higher as I went along but at around 80kg it really stated to shoot up, this coincided with a time where I began to lose weight rapidly, I now average over 100. Again take this with a pinch of salt but maybe that was me subconsciously compensating for a lack of power, due to some muscle loss?

@@chris1275cc interesting stuff. Thanks for the replies. I try to keep my cadence as high as possible, as I've simply not got the power in the legs, and find it essential. Would like to look into a question that occurred to me the other day - as power is torque (how hard you press the pedal) x rotation, when does lower power but increased cadence producing the same power value start to become inefficient or impossible to maintain.

@@jgogl9791 For guys with over 20 kg to lose, they don’t tend to lose muscle that likely because there’s just so much fat to lose. Folks worry too much about “lose muscle”, but that’s really a already very lean pro’s thing when they try to push BF to the extreme. Just like that steak you eat the other night, what looks like a strong and lean muscle on your body actually contains a lot more fat than you expect. When you lose fat your muscle “shrinks” but chances are they are just fat. As your second question, I believe (also from my own experience) that strength is more of a muscular system thing, while cadence is more of a cardio system thing. One factor could limit the other. When my cardio was very weak, for just 190w on a 2hr all-out climb, my average HR is a flatlined 195bpm for 2hrs, but those muscles are just OK. Later when my cardio become stronger, I noticed it’s always my muscle first gives up, but HR never reaches that high for that long. In the meantime I’m pretty sure my max HR doesn’t drop, I could still reach 200+ in short period of time, but other system always gives up first. Then I found when I intentionally adopt a high cadence stroke, my HR could go higher without the muscle giving up, and could squeeze some extra watts. That’s when I began to think about the same question about torque and cadence. For the same power within my FTP I can always choose either a higher HR with little muscle “exertion” or a lower HR with more muscle “exertion”. I believe you have to work both system.

I also think you should do the vested test before the non-vest test. Also add downhill test. I need to push very hard just to hang with heavier guys on downhill when they rest

We are in exactly the same situation. Same weight, my height is 6'6", no way I can keep up with smaller guys in my area

@@walker986 I ride on the road mostly for general fitness level and social aspects -- but compete in Master's B cyclocross and Criterium races. In a crit I can hold my own because they're flat and power helps and in a cross I'm usually middle of the field which is fun!

The Samurai Jack training 👌

Yeah. Bigger bodies would do even worse on this test
