Automated Bike Fit Measurement App Review: Bike Fast Fit

IMG_4624

I want to start off by first noting just how rare it is that I write an entire post specifically about a single app.  I could probably count the number of times I’ve done that in 6 years on one hand.  I simply find that most of the good apps out there are already known, and most of the others tend to suck be less awesome.

Nonetheless, I get bombarded with devs wanting me to post about their apps.  Many of them believing that a 99 cent redeemable app code will entice me (C’mon, I buy $400 watches to support readers in reviews, I think I can afford 99 cents!).

So, this afternoon while reading through e-mail I saw another app, and almost tossed it into the bin of things I won’t be reviewing.  But after poking around the link I was actually surprised – it claimed to do something I hadn’t seen before: Real-time analysis of your bike fit – including angles and distances.

So, I re-arranged my entire living room to try it out.  Why did I have to do that you ask?  Well, it turns out that in order to get far enough away from my bike to get the full view I had to go about 10 feet away.  Or, approximately 1 foot from the wall.  In fact, the camera taking this photo was literally up against the wall shooting somewhat blindly.

IMG_4617

Next, after getting my phone in the right position I cracked open the app and got the wheels lined up using the red circles.  It wasn’t quite an exactly perfect fit, but I made it work as best as possible.

(Update: A few people have asked how I attached the iPhone to the tripod. I use a tiny little adapter you can see there called ‘Glif’, which can also double as a way to keep the phone upright simply on a desk/flat surface (balances it).  I always have it in my backpack so if I need to take shots somewhere I can without a tripod.)

Then, I set the self-timer.  You can set how long to wait, as well as how long a video to record.  In my case, I went with the 30s for both.

IMG_3120

IMG_3121

Then, I ran to my bike and pedaled.  This part wasn’t terribly exciting.

IMG_4622

After pedaling, I went back to the app, and it was ready.  At this point you’ve got a drop-down menu of different angles you can have the app spit out at you.  These are all common fit angles that are most often used to describe bike positions:

IMG_3138

Picking a common one, I then can see what it believes my angles were.  In some cases, they’re near perfect:

IMG_3133

But in others, I may need to adjust them slightly (like where it selects my hip, so I adjusted it):

IMG_3127

To adjust them, I highlight the green glowing blob, which moves the piece connected to it.  This is moderately brilliant because it means you can actually see what’s being moved – as opposed to having said spot be directly under your finger.

IMG_3129

I also zoom in and modify things:

IMG_3113

Within the video, I can easily move it frame by frame using the dial on the left hand side – like a scrolling wheel.  Again, this works exceptionally well and is a thousand times better than trying to play ‘drag a dot’ on a line.

As I add measurements, it’ll tell me about 5-7 paragraphs about each measurement, including general guidance on acceptable ranges.  Of course, there can always be exceptions, but this should you understand if you’re in the ballpark:

IMG_3142

In addition to angles the app can also do distance measurements.  All you’ll need to do is tell it some random distance of your choosing on the bike, and the measurement of that distance.  So I did that:

IMG_3109

IMG_3110

Then, from there on out it can measure everything else:

IMG_3111

And also do random angles for any three points you’d like – such as this totally useful angle combination I randomly created:

IMG_3132

You can save multiple bike profiles and riders and multiple analysis sessions:

IMG_3114

IMG_3126

As you ‘add’ measurements in, it’ll list them in a summary page, one after another (it does all the measurements for you – you just validate them):

IMG_3139

While the app handles hip angles and the like for triathlon/TT bikes, when it comes to measurements around the handlebars, it’s more focused on road bikes:

IMG_3140

Additionally, you can also do a front view as well, though I didn’t do that tonight:

IMG_3122

At any point you can simply tap to share a given fit angle and/or measurement.  For example tweeted or e-mailed:

IMG_3116

Overall, this app is pretty damn cool.  Mostly because it’s actually useful – especially for athletes that may not be right next to their coaches and/or fitters and want to poke around at new positions a bit (or validate old ones).

Now, I don’t actually believe this should replace a fit from a proper bike fitter.  Really, I don’t.  But in many ways this substitutes for the highly expensive Retül system that some fitters have (the computer portion anyway), which uses little placed sticker dots onto the athlete and calculates the same angles.  In this app’s case, the app simply recognizes human body parts and does that for you.  It would be cool though if you could place little sticker dots (like these) on the correct body part spots (knee/hip/ankle) and have the app pick those up (for higher level accuracy). (Updated note: As pointed out in the comments, you can definitely still do the dots now, which will improve accuracy when it comes to manually adjusting anything you might need to on the screen.  Good call!)

I also think it gives an athlete an opportunity to quickly share fit details as needed.  For example, when I spent some time at the LA Velodrome back in the spring, in talking with renowned bike fitter Jim Manton, he mentioned a funny story where a well known pro triathlete had come in for a fit.  About a month later Jim had seen a race photo of the athlete in a news clip from that weekend.  Turns out, while re-assembling the bike after travel things got a bit out of whack.

No doubt that issue could be solved a bunch of different ways (like a tape measure).  However, one interesting way would be for a friend to simply take 10 seconds to take a video of the athlete after setting up the bike and ensuring the angles are all the same (since it automatically does all that).  The angles could have acted as a quick double-check.

Or, probably more practically it can just be used to quickly see what your own fit angles are, and documenting them.

Now there are a few things I’d like to see however in the app, which I suspect are probably minor adds for the developer:

1) I’d love to be able to upload the videos recorded from the app with the angle information shown in real-time – right now this is all internal to the app (and isn’t put into your camera roll).
2) All of the angle references are listed on the screen as you add them, but I’d like to see that information also transmitted with the e-mail like the photos are.  Currently only the angle you’re looking at is included in the e-mail information.
3) I’d like to be able to share the raw video with my coach/fitter so he could tweak the angles as need be in the app.  Right now everything happens on my phone.  Since my coach lives 3,861 miles away – it’d be great if I could setup the video, include the reference distance (if I wanted) and then let him go to town on looking at angles.

Obviously, there’s lots of things as a non-fitter I’m likely skipping over (both pros and cons), but, as a bit of a bike geek, this caught my eye as fairly useful – especially in a solo person capacity where you’re trying to take your own bike fit angles (obviously, to post on Slowtwitch and be told your seatpost is too low).

At any rate, the app costs $2.99 and works on all Apple iDevices (with an iPad variant).

Thanks for reading!

(Update at 10:15AM EDT: For those asking about Android, the developer has let me know they are working on one, it’s just that they’ve primarily been an iOS development shop in the past so the Android side is taking a bit longer to release.)

      Its a great app, but as only as good as the user...it helps if you know how to landmark the body properly as that is how the min-max angles are determined

  3. Hi Dc,
    Let me start by complementing on your research methods. they seem very practical and useful for a lot athletes.

    Bike fit
    Without getting into details of what angles are the best for a rider. i agree that ubersense is a great tool to use for all kind of sport analysis. not only for cycling but also for running, swimming, skating, etc
    You mention Retül in your blog. these are just a couple of computer guys who marketeerd their system very well before selling it. In Europe we call that the basic American business model (create, marketeer and sell). try to find some technical detail about the system and you cannot.

    i Do think that this setup is a one that can help you with your fit. however there are a couple of notes you need to consider.
    > a bike fit is never only based on the solely measurement of angles. It also has to to with body symmetric, history, length differences of body part, differentiation in facial balance, upper end lower body length, type of muscles, pushing technique and changes in some of the parameters during the periodisation of your season.
    the other thing that seems to be important in this is time. the longer you sit in a position the better you get an idea of what you can or cannot do. this holds an direct relationship between the upper part.

    from a technical point of view it is important to use a camera with a flat lens.when this is not applied. The measurement will not be trustworthy.

    In order to do a good bikefit that is reproduceable an trusworthy to show you need more that a camera and an app. Underneath i posted a link to an thesis of an mathemattical student. This wil give you an insight of what to do when you want to bike fit propperly.

    link to few.vu.nl

    Let me end this comment by saying that i really believe that the ubersense could be helpfull in many ways. specially for people who did not do anything. But to fit specially you need a specialist. Retül fitters are not one of them as i see it. (i that case you do the same).

    hopefully this will help to get an slightly different inside.

      Great comment Chris,

      I totally agree with your comments, as well as the inaccuracies of the measurement of the angles. If the 'dots' get placed incorrectly (that is a big red circle covering a reasonable amount of surface area) and error will be introduced. Although DC does point out it should not replace a qualified fit and then can be used for confirmation.

      My question is: Is there an English version of your article? As I am keen to read it.

      Hi Chris and Ray B.

      You bring up a good point about the red dot being large enough to not be able to accurately place it. We address this by hollowing out the red dot and making it a circle when you use the green handle to activate the line and place the dot. You can see an example on the first screen shot on the Apple marketing page. Here's a link:

      link to itunes.apple.com

      This allows you to use the point created by the two lines to accurately place the dot.

      If you have ideas to make it better let us know. We are working on a list of ideas for version 2.0.

    Cool App! You need to take the knee measurements from consistent places though. You're measuring from different places in most of the screenshots and will get inaccurate readings from where it was on the screenshots. Greater Trochanter (bony hip bone at top of femur) --> Lateral femoral condyle (bony protrusion at bottom of femur above knee) --> lateral malleolus (bony protrusion at ankle). Of course, nothing beats hands on fitting with a trained fitter with a goniometer and plum bob.

    You can add to the $2.99 cost of the app the full cost of a rear-wheel-on trainer. Since the app starts out by imaging both wheels, it seems it wouldn't work with a rear-wheel-off type trainer such as the Wahoo KICKR or Lemond Revolution.

    Reply
    • Shalmaneser replied

      Why would it not work with a rear wheel off style trainer? As long as the bike is level, and the dropouts (F+R) are in the centre of the red circles then it should work fine.

      Reply
    • Mark replied

      Dunno. Shalmaneser may be right. But looking at DCR's photo, it looks like the app wants to image the entire wheel. It would be interesting to hear what the app developer says about this.

      Reply
    • Terry Millard replied

      Hi Mark,

      The red alignment outline is only used to help the user properly align the camera and the bike. During development we found we typically setup the camera too close and cut off our head (well in the video and not actually.) We added to alignment to make setup easier.

      The angle and measurement tools will work with any type of trainer.

      During development we tested it by using the app to capture video from You Tube videos of bike races. The angles worked even with this method.

      Happy to answer any questions or comments.

      Though, I generally don't notice the bells anymore unless they go into crazy-nonstop mode (occasionally, for 15-30 minutes at a time). On the flip side, I do sometimes subconsciously calculate the time from the bells without thinking.

    Ray Maker: "It would be cool though if you could place little sticker dots (like these) on the correct body part spots (knee/hip/ankle) and have the app pick those up (for higher level accuracy)."

    It still could be better to use dot stickers even if the app doesn't recognize them automatically.

    The app could put holes in the red dots on the image to make the positioning easier.

      Hi Eric,

      We recommend 10 feet but it isn't necessary. You can use whatever distance you have available. You may need to take 2 or 3 videos to capture the enough of you and the bike to measure the angles you want measured.

    I have started playing with dynamic bike fits. I use a gopro and free software for the laptop called kinovea. Overcomes almost all the shortcomings dc listed. Also with the wide angle lense and high framerate allows usage in confined spaces and less blurring. I then output the overlay images with angles etc. to a word doc report to keep track of things. Much like what you'd get from Retul I'd imagine but with all free software and some basic hardware. But an experienced person understanding the body physiology and fit techniques driving these type of tools is the key. Having said that, for a quick and dirty check of position, this app looks great!

    Hi Ray,
    thanks for that Review. I´d support the Chris´ comment although one could use the app and measure both sides of a rider (?) to check Body (parts) differences?! Nevertheless, differences in femur (etc) length are more crucial than ca. angles of legs! But, you alreday mentioned, it does not replace the pro bike fitting. Secondly those "perfect" angles, are a serious matter of debate. Pro bike fitters would definitely not want to live with "angles between 140-150° are good for the average rider".
    I saw some pictures of you on a bike, since I started reading your Reviews. I (oftenly) thought you are chosing a very high riding position, ie your leg is streched out. At least on the TT bike, I again have got that impression.
    I am a cyclist since 28 y and also was a trainer, so I might have "an eye for that". I recently used the University Freiburg aka Olympia Center method for my personal fitting. Which fitting Parameter do you/does your trainer believe in/use?

    Good app, when I was in uni and didn't have the money to pay a bike fit I used to set up my laptop, film myself and fit myself in the same way. Since a home fitting like this will likely be done in house where a laptop is available, do you know if there are plans to release a small software package for laptops? The bigger screen will help accuracy as well.

    As others have mentioned using stickers on the hip, knee and ankle points and getting the app to recognise these should be the next development. This is what the Specialised BG Fit system is based around.

    Re: Retul. The problem with this system is it takes a few measurements of an individual and tries to fit these to an internal model which represents an average body and then calculate bike dimensions from this. This is OK if you happen to have a body which matches this average but if you're outside this model then it can produce wrong data.

    Thanks

    Nice review of a very usefull app. Through I'm very cautious with these kind of apps because now everyone can fiddle around thinking what they do is correct without having any proper knowledge of matters. One thing I miss in the comments though is the measurement error because of the size of the images. I've read an article (don't really know who wrote it, just since a couple of months started saving interesting articles) of a comparison between the reliability of retul vs video capture. Video capture had a pretty impressive measurement error because you have to place the markers in the correct place on a computer screen. The size is with a big screen max 30x20 cm's or so? That implies that when you place the marker on screen 1 mm off, it will represent a couple of mm's on the body. Just imagine what 1mm on an iPhone screen will be in terms of measurement error. I'm not implying that this app is useless, on the contrary (the pro's have been mentioned before, I don't have to repeat them i think), just be cautious with these things.

    Reply
  40. If I may I'd like to address some of the statements above on Retul. For full disclosure, I am an experienced bike fitter with experience spanning 30 years, and I use Retul hardware and software, amongst other tools, when fitting. I'm also a competitive cyclist and licensed professional engineer with a masters degree in mechanical engineering.

    Firstly, this is a very cool app! I certainly see a lot of wonky positions out there and this tool has the potential to help a lot of people find a better position on their bike. I'm intrigued and definitely buying it.

    Secondly, it is not a Retul replacement. Retul is dynamic (collects data while you are pedaling), it is real-time (not based on post-processing of video), it works in three dimensions (not a side view), and it is highly accurate (sub-mm). This app, while a cool and potentially useful tool, is none of these things.

    On the claim above that Retul is a marketing company, I invite the poster to do a bit of Google research on this as the fact is that the creators of Retul are very clever folks with both sport science and technical backgrounds, and quite deep ones at that. The post above stating that Retul "takes a few measurements of an individual and tries to fit these to an internal model which represents an average body" is completely incorrect. Retul is a tool that presents large amounts of data (over 25 measurements per data capture, and one would conduct many data captures per fitting) for interpretation by a qualified fitter. It is essentially a very sophisticated plumb bob, ruler, and goniometer.

    Thanks for the review Ray. I'm a huge fan.

      Thank you for the refreshing and technical clarification -- too many comments in the blogoshpere are too earnestly presented, yet completely lack technical qualifications, and remain utterly blind to the fact that the commentary lacks sufficient scientific foundation to exist as presented.

      Remember people, there is a huge difference between what we BELIEVE we know and what we actually, factually KNOW -- sadly that difference often is the difference between fact and fiction.

      Nice to have someone with authority to shout down those without knowledge. I just did the Retul fitting form my training bike, Crit bike and MTB bike. It is very impressive stuff. Found the (major brand) saddle I use on the crit bike had collapsed on one side, hence my left knee being closer to the top tube. Also found the BG fit settings I had done 18 month prior positioned me a long way back on the bike.

      I also like the new cleat position and the discussions over stretching and looking after myself off the bike.

      I like this APP because I can show my wife what she looks like on the bike and also the measurements and angles so she believes me when I say we need to adjust the posture.

      Will use this app with cycling friends on the local club as an anti injury aid.

      Hi Jacob,

      We goofed. We introduced a software bug during testing on version 1.10 and didn't catch it. We identified and fixed the issue and submitted version 1.11 to Apple a couple of days ago. We expect Apple will approve the new version within a day or two.

      We are sorry for the problem. We have modified our testing and release procedures to make sure this type of error does not happen in the future.

      I have several emails from you and I will respond to those also.

      Sorry, Terry

    Would one be able to use this software _without_ a trainer? For example just leaning on a wall and pedaling backwards. Interested to give it a try just because I recently acquired an iPhone.

  44. Hey Ray.

    I've noticed a Xlab aero bottle on your aero bar. How do you like it? Or my eyes are fooling me?

      Funny how few people caught that...

      I do like it. It was a bit of a fugly mess to get installed (way more complex than it needs to be, but, then again, I don't design waterbottle systems for a living). That said, I like it. It resolves most of the issues I've had with other systems (for example, others, you couldn't actually see said Garmin).

      At some point between now and next spring I'll write something up on it. Most of my training right now is focused on running, and then a lot more indoors.

  45. Well. I am just thinking of an aero bottle right now. From my inspecting the market the XLab Torpedo looks the best to me. Other horizontal bottles like Profile Design A2 or the new one you've mentioned a bit of the time before, don't seem to be very good to me. Thank for the reply, by the way. I guess, I am going buy it now, no doubt.

  46. Hello,

    Discovered the app through yr review and am very quite happy with it. Helped me quite a bunch to position myself on my new TT bike.

    I have trouble with one thing.

    Do you know how (if possible) delete the videos once you have quite few of them?

    Best regards,

    Alexandre

      Hi Gerard,

      Terry from Bike Fast Fit here. Thank you for your patience. Android is in development (really). We expect release in late May or early June.

      We are slower with the Android release then we intended at first due to some of the ideas for enhancements we've received from users. We want to incorporate many of your product ideas and this caused us to undertake some redesigns of the base structure in order to setup the infrastructure for future product enhancements.

      Thanks for your patience.
      Terry

    Great app. I replaced several components including saddle and aerobars since my last fit and had unintentionally moved further forward than I realized. Wish I would have taken a baseline with the app a year ago before the changes. Now I'm adjusting my position back in small increments over time and taking shots at each step. A suggestion to the app developer - it would be cool to be able to manually flag a measurement that you are concerned about so that you could see at a glance which ones are "out" from the list. As they are interdependent it would aid in pointing to common cause. Thanks for a great tool.

    $6.49 in Australia Itunes store - has the app gone up since it came out everywhere else. Read through the review and thought I would give it a go for the price but then changed my mind at that price !

    Where's the Android version?

  56. We regret to announce we have put our Android development of Bike Fast Fit on hold.  We are a small company with limited development resources and a long list of ideas for improving Bike Fast Fit.  Our goal is to build the best bike fitting app.  We decided to concentrate on improving the iOS app rather than build an Android version.

      So you're going to limit your sales and when someone comes along with a similar app. For both technologies yours will be history.

    I just paid for a Retul fit and can say it looks like this app + the knowledge I learned about cleat position from Retul and you have a bike fit option to help your buddies out. Even amateur clubs where riders cannot easily spring the 250 for the retul fit can be helped and possibly saved from injury.

    I say this because having a video of themselves is SO important in getting across to them that the posture they currently have sucks. They know what others look like on a bike but not themselves.

    Awesome that you take the time to create such a good read too!!!

    Just another idea. The user guide should include advising the test rider to use stick on dots like they use at the bike fits to mark each of the joins locations. This will make it easier to measure the angles on the captured video.
    Locations were: outside little toe (5th metatarsal), heel outside at same level on the side of the shoe as the metatarsal spot, ankle bone, knee hinge point, hip hinge point, shoulder hinge point, outside of the elbow hinge point, wrist bone outside, 1st knuckle on index finger.

    Get these right and you are in for an awesome fit.

    Looking for a bike fit app on Android? I'm the developer behind The Roadie Bike Fit. Turbo trainer not required! It has literally just been released so it will probably take a while before it is searchable in the playstore but here's a direct link. If you buy, any feedback really appreciated!

    Ray, have you checked the Roadie Bike Fit for android is equivalent to the Bike Fast Fit for iPhone?

    In any case thanks for all the great reviews, comments, stories of this great web. Thanks for all. Paco

      I looked at the screenshots, but haven't looked at the app yet. There's also a third app as well (for iOS right now), here: link to itunes.apple.com

      I might look at all the apps in the coming months and just do a light comparison. We'll see.

      Ray,

      Thanks that would be great.

      I think many of us with all the heart rate belts, power meters, cadence/speed, GPS, apps, watch, this and that finally we are not well fit on our bikes :-) so decrease performance and increase pain an injuries.

      As you said that is not a professional bike fit but I guess at least you should get some basics that helps to prevent bad positions, etc

      Thanks again
