Detect E-Bikes users and flag them

From last year, at least for me, we have seen how some unknown riders got super-human records at the climbing segments, beating the best local riders in almost every popular place. 

I know a lot of us have been flagging these activities because it was clearly made with an electric bicycle (not a motorcycle like past years), and we know that every time they are the same guys we are flagging week per week.

I think there must be an algorythm detecting these constact flagged riders as an "ebiker" an should be asked after the ride if they were using an Ebike, so the activity would be saved as an "ebike ride" and saving a lot of people's time flagging these guys. Or if we go more stricted, making "ebike ride" their Default activity after the every ride.

 

Cheers.

    We recently released a new detection system to automatically identify and remove activities containing data anomalies from leaderboards. This system is not retroactive and will be applied to new activity uploads only. However, we are committed to continually improving upon our auto-flagging system and are looking into ways of cleaning up historical data. As always, our community has tools to help maintain leaderboard integrity through the activity flag tool, which you can read about here.

  • I agree.

    The major problem, at least here in Europe, is the almost useless e-Bike category without any subcategories like EU-Pedelec, U.S.-Pedelec, S-Pedelec.

    These 3 eBike categories are very different to each other. Very different traffic laws apply. 

    EU-Pedelec users see themselves (because they are) very much closer to bicycles than to more powerful rare S-Pedelecs. (engines support till 45 km/h up to 4000 watts while EU-Pedelecs allowed on normal bicycle lanes and in forests, city-parks support only with maximally 250 watts and only till 25 km/h, still enough for many KOM despite the extra-weight of around 15 kg.)

  • As an e-bike commuter, I support making "e-bike ride" as a selectable default activity to be associated with the bike in the gear menu.

    After almost 1400 miles of commuting and tracking with strava, it's annoying to have to manually toggle it over to ebike ride every time. I would like it to be a setting that could be overrided to bike as I occasionally ride it with the assist off to get a fitness benchmark and assess how much I am relying on the assist.

    As a side note, it would be nice if e-bikes could get their own segments and challenges for added motivation. I may not be working as hard as I would if I was pedaling unassisted but it's a huge improvement over sitting in the car.

  • Yes!  This is ridiculous!  How hard could it possibly be to separate out the different types of biking?  This has been going on far too long without any progress.  How the heck are mtb'ers supposed to compete against road and gravel bikers for distance or against e-mtb'ers for time?  How are road/gravel bikers supposed to compete agains e-bikers for mileage?  Come on Strava.  Do something about this!

  • Hi, I just got a E BIKE, its great for commuting, and its a mountain bike , Anyway , my miles don't count for my cycling club because its an ebike. Any one with an ebike knows your still pedaling your but off. I'm thinking of dropping the premium strava.

  • Nice resume all.

    Fully agree with you. EU eMTB are not motorbike like in USA.
    I will ask soon to be refund if Strava is not able to deliver the same feature for my MTB and my eMTB. Then migrate to another tool.

  • So today when I was driving home I drove a path that someone has a 16 segment and is dominating the leaderboards and i was driving 45 and clocked 11. all i gotta say is i hope strava does something about this. its not fair to the people who are pedaling vs twisting the wrist. So annoying and really hope something happens to give the segments back to the riders. so disappointed about this fake news that is ebikes

  • Breaking news: heavy bike limited to 25km/h go faster than a competition bike you ride at 45km/h. ^^

    As usual, lot of hate and no fact. The best Strava could do is to kick out dumb users

  • Hey Sylvain: your disrespectful attitude toward other members isn't helping your argument, not that you've actually made much of an argument. eBikes are a different category of bike--it's just that simple. As such they should be separately segregated within Strava.

  • What activity TYPE should I use for a very strong e-bike? I can easily ride hard uphils at 45km/h, straights at around 75mkm/h max.... 

    Can we have the categories on power of the motors? Watts? KW? Something? Also, my partner was using an electric motorcycle, 3000w, a soft enduro motorcycle, but much stronger than my old 500w mountain e-bike ..

    Also, where can I ask what is a work-out category??? also, what and how to you time a yoga ??

    Found some basic help out of 2012 on strava, last few categories look like this:

    • Stair Stepper
    • Stand Up Paddle
    • Surf
    • Virtual Ride
    • Virtual Run
    • Weight Training
    • Windsurf Session
    • Wheelchair
    • Workout
    • Yoga

  • There are two types of e-bikers. Those oblivious to what they are doing on Strava, and those who do know what they are doing and are cheating legit riders on purpose. If flagged they should be permanently banned from eBay or banned for 4 years like someone testing positive. It’s the only way to get Strava back to it’s intended purpose. If Strava doesn’t step up, and soon, they are going to lose a large number of participants including me. Waiting for e-bikes to start invading zwift. Read an article recently by a mtb writer who said they welcomed e-bikes. They already have that it’s called motocross. I’ve read where they say it helps include more people but they don’t have to get on Strava. COME ON!!!

  • Repeat offenders should definitely be permanently banned from participating in leaderboards—not just for a few weeks, months, years, etc.

    There’s no reason it should be so easy to tag hundreds of bike rides as runs, etc. while making it so painful for legitimate users to flag those hundreds of activities, when in the end, the cheaters will just keep adding more disqualifying activities and get rewarded for it.

  • Why the hell is Strava, not helping athletes, when it is a site for athletes? E-bike rides on Strava sould be SEPARATED.  Do something about it. I can not understand that a company like Strave, whose core business are athletes, are so lacking here do freaking do something about this. Write an algo, detect it yourself. and At least, when a ebike athlete has been flagged a couple of times, it would be damn easy for Strava to build in a question to check if it was done with an E-bike again.

     

    Strava support department is terrible. They're not listening.

  • Is it Strava Support or Useless Muppets?

    How can they continuously ignore so many loyal customers for so long; there are some very simple additions they can easily make to help everyone get along on the roads & trails.

    I ride with a couple of ebikers when they are too lazy to use a normal bike & they are also too lazy to change the activity manually.

    SIMPLE STRAVA:- PLEASE MAKE IT EASIER FOR THESE LAZY PEOPLE!

  • Strava has said that it has improved its algorithm to detect this. But it's not like that at all. I see every days users registering KOM's on Strava, which suddenly improve from being in position 5000, now they are in the top 10, going up 10 degrees slope on dirt roads to almost 30M / h. Is it very complex to implement an algorithm that detects the difference in the trend? When is this sudden...Or imposible pace?, I see many runners with more pace than Kipchoge, running at 35K/H, they carry all's KOM's.... is disaster....extremly annoying

  • Strava needs to count the Flaggings of a rider and lock out their account when they’ve been flagged multiple times.

  • "SIMPLE STRAVA:- PLEASE MAKE IT EASIER FOR THESE LAZY PEOPLE!"

    This is the way forward. The algorithm only detects the extremes (if you upload a manually created GPX file with an average speed of 500kmh and upload it, it will get flagged immediately). It does not detect people riding all day long down MTB trails and then destroying XC riders uphill on their 10th climb back up. Neither does it detect someone who leaves their phone on and drives 10 miles home at 100kmh and claims all the segments on the way (but this isn't the place to talk about that).

    Repeat offenders should be dealt with. As it stands, if they are flagged they can simply keep on selecting the option of "It's fine, trust me" and the time is reinstated, no questions asked. It's an absolute joke. This has been going on for years and is only going to get worse, yet Strava still seems happy to just let it carry on and take the fun out of the best feature they have going. Poor show.

  • I don't have a problem with anyone owning an ebike, it's when they leave their Strava settings for an unassisted bike and then coo to everyone how fast they are. Ride your ebikes if thats what you want but put them on the ebike setting.

  • Also if a rider blocks you their repeated cheating can no longer be flagged.

  • I was passed by a guy on an e-bike when I was riding my road bike at 36 Km/h.  Clearly, e-bikes are not limited to 25 km/h in Europe (UK).  I flagged his ride, which included a couple of KOMs (not on the segment where he passed me).

    E-bikes are a problem.  Let's face it, they are basically low powered motorcycles.  If declared and ineligible for any leader boards, then that's OK, but the problem is that many don't declare their use.  In my opinion, Strava is for "athletes" who run or ride without any power assistance.  There should be a separate site for e-bikes and their use should be banned from the main Strava site.

  • I grudge continuing paying for membership if Strava aren't going to take this more seriously.  The segments are one of the things that most of us enjoy no matter our abilities.  Having seen a local women on Facebook openly talk about getting a new e-bike, then proceed to log a ride almost double her previous speeds and take an uphill QOM displacing an excellent club rider that has most of the QOM's around here.  I flagged it but the ride appeared back again so I've flagged it again and will continue to do so until she changes her ride description to e-bike.

  • This issue will only become more common and it's probably not able to be solved by Strava. Perhaps people just need to check their ego in at the door if they can't handle being nudged down an imaginary internet leaderboard. So many K/QOMs seem to be pre-planned attempts with warm up, wind, etc taken into account, they are hardly representative of anything much beyond how much coffee someone drunk before setting off. 

    As nice as it would be, it's difficult to see what Strava could do about this when there is so much variety in e-bikes and riders anyway. There will always be the outrageous ones that anyone can spot (even an algorithm) but there will also be riders that give just enough of a motorised nudge to claim the leader spot. 

    Age adjusted positioning would be easier and much more popular - maybe that's all an e-bike is doing anyway. ;)

  • You are right, but there are two things, it is still pathetic and selfish because for many people the sport is serious thing, and on the other hand, we are paying for a service that provides us with increasingly contaminated information.

  • Christian, I agree with you. I don't see a solution though because the world will always have fragile egos who want to cheat and other fragile egos who care about an internet leaderboard of strangers. 

    Talking of pathetic, my previous post has been down-voted by some of those fragile egos. LOL :)

  • Seriously, the biker rage on this forum doesn’t paint a great picture of the cycling community. I’ve been around Strava since the beginning and it’s fun to look at segments but I hope people are aware that there is no real prize for winning the KOM/QOM. Don’t take your privilege to ride/own a bike, feel good about yourself, etc. for granted and act out like an entitled Karen. I bought a Pinarello Dyodo Gravel (ebike) for mixed road adventure rides where I could save my legs on climbs and turn off the system when not needed and it’s something that I can see any serious cyclist embracing because 1) most serious cyclists have been in a position where they bonked in the middle of nowhere and needed a miracle to get back 2) when you’ve loaded your bike up with gear having a boost up an incline isn’t “cheating” it’s just being smart. 3) Not everyone using Strava is trying to “cheat”. They’re just tracking their rides and their fitness. Chill. 4) I could go on but some here only want to perpetuate the very tired bike snob ethos. Some of us enjoy throwing down 10 w/kg just as much as we enjoy riding for fun without unneeded suffering. Obviously something needs to be done about ebike categories but if it doesn’t happen overnight I doubt this forum is going to make it happen sooner. I’m sure the issue has already been raised within Strava. If you’re bitter about losing a segment you should still feel just fine knowing that you’re the “real” winner in the same way that Zwifters use zwiftpower as a layer to sort out results between the “legit” racers.

  • I am not far from conclusion that leaderboards are becoming useless. It's is more and more polluted by e-bikes. I am not the one to win any KOM, but it would be nice to know, how I look like in comparison to bikers of my age or in general population.
    I checked several segments especially interesting for me. In some cases 5 of 10 first places are occupied by e-bike rides. Many of E-bikers start their rides right from e-bike rental and ruin the leaderboard so these cases are more than obvious. What should honest biker do? Scan first hundred places and manually eliminate e-bike rides? It's nonsens. It should be done automatically. 
    I believe many of those e-riders are unaware that if they don't pick e-bike as activity type, they ruin fun for others. Maybe each time the ride is downloaded Strava should explicitly ask if the ride was motor-assisted? Until the question is answered the ride shouldn't be presented on leaderboard.

  • Kevin Lu is off base. Part of the fun of Strava is comparing yourself to others. The e bike rides can use Strava to log their rides, etc. but they don’t have to post them. Very simple solution. What is the point if them posting?

  • 10 months I ride MTB for stamina and eMTB for fun and explosiveness. My conclusion in my country:

    * same hate from some classic biker against ebiker. Some of them shouted me. After exchange, none of them practice competition. When I said I stopped XC competition 25 years ago and I started boxing competition 4 years ago, they said I misunderstood their kind words. Phew! 

    * no ebike cheater. 2 classifications issues changed by eriders. But 2 classic bikers shortcut some technical segments to win the precious KOM.

    * I ride regularly with semi-pro bikers and it's impossible to win a decent KOM with an eMTB against a MTB

    If you see ebiker ahead of you, you need probably more training to get the beginner sportsman level and you need to find a real segment to practice a bit
