I am the inventor of LITPro (hardware and apps) and so my point of view is pretty biased Wink , but I can tell you what we did to make the best possible product for motocross.

1. As someone pointed out already, most of our product by weight/volume is a ceramic GPS antenna. It's huge compared to other products and the single most expensive internal component to LITPro
2. Our GPS operates at 20hz. Compared to other products we are at least 2x the resolution and in many cases 20x the resolution. And our GPS engine is designed for vehicles that change directions quickly as opposed to straight-line (like you would use in your car). This is a huge differentiator because if you are going 30mph and you track at 1hz (1 time per second) then your data points are 13 meters apart and with that it is impossible to describe a corner.
3. We do sensor fusion and combine a bunch of internal sensor data like gyro and accelerometer to give us a ton of data about what you are doing (in the air, on a start, in a corner, in a crash, etc). Our sensors and algorithms are calibrated and designed for MX and no-other product we know of can claim this.

Regarding the comment about seeing some strange accuracy stuff from Supercross data. We do struggle a little (like all GPS products will) inside of a stadium with the stadium walls blocking satellites on the horizon. The GPS satellites on the horizon are the most important ones because they provide the best geometry. In normal riding conditions like where the Supercross teams train and where public motocross tracks are typically the GPS accuracy will be much higher - like in the screenshot above. Under normal conditions (not in a stadium or on the side of a mountain) we can confidently distinguish between riding two different ruts that are 6 inches to a foot apart (more about this below).

Relative accuracy vs absolute accuracy...
For the fellow nerds out there Wink No GPS product can claim a certain level of absolute accuracy in feet or meters or whatever and if they try to do that it is a complete lie. Claiming relative accuracy is much more possible to do however... Here's why. Absolute accuracy is like painting an X on the ground out your front door and then putting the GPS product there and then for 20 days straight the GPS product reports the same exact position every time no matter the circumstances (like the satellites are moving all around in the sky, a big truck comes and parks next to it, a group of people come and stand around it, etc). The position reported will change all over the place, sometimes by much more than 3 meters guaranteed. Relative accuracy is different though and is an important distinction because of how GPS engines come up with their position solution. Relative accuracy means that the amount of error from one solution to the next solution is limited to a specific amount, and maybe that is a few inches or for some products that may be a few feet. Relative accuracy basically introduces a time component to things. The absolute accuracy can still be off by a few feet, but you just aren't seeing the 5-foot shift happen 20 times a second or whatever creating a huge scatter of dots on the map when nothing is moving...

With LITPro we benefit a ton from the relative accuracy of our GPS technology. In great GPS environments (like Pala raceway here in so-cal) our data looks so good it seems like we are using a smoothing algorithm to cheat (we don't... it's raw data always). In difficult GPS environments, like a track on the side of a steep mountain, our data can have a 3-meter error to it. But because of what we do to control the error, and because we know what's going on inside the GPS engine, we can still typically distinguish between which rut you took in the corner, and thanks to the super-high relative accuracy of LITPro what you will see is an entire session of 20 laps or whatever where the entire session is shifted by 3-meters in the same direction. So when this happens you can still see which rut you were in, even when the ruts are only a foot apart, and what it looks like happened is the image of the track is what shifted. And our LITPro apps allow you to easily shift the image back underneath the route lines so that everything lines up again.

Here's an easy test for anyone with a LITPro already to see how this all works. Turn on your LITPro and find a spot outdoors, turn on tracking, and just stand in the same place for 1 minute, or maybe even just walk around for a minute and sync the data and look how ugly it is. It will probably jump around and look kinda jagged and wiggly. It is important for this test to stay below 5mph. Now do a test where you are moving at around 8mph or faster and look how smooth the data becomes. This is part of the beauty of our design and us taking advantage of the relative accuracy of our GPS engine to make a great motocross product. In the second test your data will smooth out a ton and start to look really clean. The more you move like a motocross bike does, the more our system stops guessing about changes in directions and we just pin it to your movement.

Finally, we of course wish we could make LITPro a lot less expensive so more people could try it out - and we are working on doing that. We love motocross and built a product we love using because we ride too. Hopefully you guys can give it a shot some time soon.
This makes complete sense and now i might have to buy one. Thanks for for taking the time to explain this and thanks for making a cool, innovative, useful moto related gadget!

You can get those dongles for $135 on Ebay. Not bad at all... Although there was 1 for $35 yesterday, I think the seller made a mistake when listing one at $35 (I should have tried to buy it). I'm in the process of trying to use the MX Buddy app and the built in GPS on an old iPhone I have laying around. I thought about cutting out a Pro Taper bar pad so I can see my stats live. I'm a slow B rider, but I think it would help my lines and turning laps. But seeing this GPS, wow it has up to 10 location updates per second. Most of these devices are like 1 a second. I may have to get one myself! How long have you had yours?

I've been using it for the last 4 months. I've had a lot of fun with it so far and it's been a great training tool. The 10 points per second are why I went this route vs a GPS watch or phone.
I considered this until i saw the max speed was limited to 1,150mph. What good is it if it’s going to malfunction while I’m laying down a really hot lap?

Feel free to link up with me, guys.

ricozinn, I had an issue syncing last week and talked with Brandon. I believe he was going to talk to you and get back to me. He was just heading up to Mammoth, so I assume he spaced it out, which is no big deal. You guys do an excellent job with customer service and I thank you for that.

Thanks @T-Fish I talked to Brandon and got that sorted out.

Hey!

I am Nino, the founder of CrossBox Lap Timing. First of all, I would like to thank all the riders from the US using CrossBox already. And I would also like to mention that we know Litpro pretty well and it is a great tool too.

We are working hard to provide a state-of-the-art app that shows motocross athletes all the essential information to analyse laps and reduce the times. If you decide to buy just the XGPS160 online, of course, you could use different apps (like MX Buddy). But you need to know that your options for analysing will be limited. If you only would like to see your lap times, they will do the job. But if you would like to get more insights (f.e. to find out where you are losing time on the track, what your best lines would like like and what your theoratical lap time would be), you need to go with CrossBox or Litpro. There are so many features you will miss at other apps like:

> Comparing laps with each other
> See your theoratical best lap
> Highlight fastest lines
> Get section times (MX-Buddy shows section times but others won't)
> Play a real time animation of your laps
> Get the speed on any given position of the track
> Share laps with friends to compete in a real time animation


Next I would like to highlight the pros and cons if you compare just Litpro with CrossBox:

Pros CrossBox:

> CrossBox works offline: CrossBox will let you analyse your laps also when no internet connection is given. (Think about the amount of tracks where the internet connection is really weak) You can save a backup of your data on the server any time you reach wifi, just to make sure you never lose any data.

> Only CrossBox gives the opportunity to display all the laps in one view together with the fastest lines of each section.

> The syncing process time (loading the recorded data from the XGPS to the CrossBox app) only takes 2 minutes for a 30 minutes moto (Litpro takes appr. 10 minutes, the reason for that is the higher update rate of Litpro and the other parameters like jump analysis that the Litpro records)

We made several tests to compare the accuracy of Litpro and the XGPS + CrossBox app, together with a high-speed camera as a reference. We found out that the lap times, though the position update rate is twice as high at Litpro, show the same accuracy (maximum fluctuation +/- 0,05 seconds in both products). The reason for that is that we use interpolation to calculate lap times even with less amount of data points. Litpro is not more accurate compared to CrossBox (We will also release the test soon) Wth the current GPS-technology, it is just not possible to give better accuracy then CrossBox or Litpro. Even if your device records 100 positions/second, there is a risk that the GPS positions are shifted from the real path.

Pros Litpro:

> You will be able to analyse the jump height and jump distance, which is really good if you are a professional supercross rider.

> The current crossbox app won't let you zoom in your path and you can not record your heart rate while riding (but CrossBox is working on that and will release an update of the software, available as a free download, soon)


Just let me know if you have any questions regarding to CrossBox,

- Nino

Will any of these apps ever be able to be used together as a race timing system for results? Is that possibly being developed?

If that offer still stands, I’m a lock at fifty off.

I’ve been riding with a polar watch and an H7 HRM for a few years. Probably two years ago I missed an email or ad or something from lit pro for a Black Friday sale and tried to buy Monday or tuesday but it was back to msrp. I kick myself to this day for that.

What does Crossbox and LITPro have, that the Garmin Virb 30 does not? I assume the GPS system will be more accurate on CB and LIT, but the wording on all 3 products seems to be the same when it comes to GPS technology

I’ve been really impressed with the LItPro. Used it 4 days in the last week and it’s helping me shave multiple seconds off every track. Check out this one corner that I hit 1.5 seconds faster.

I think the owners gave a lot of good info about their products, which is extremely cool that they posted here, but I don't believe they actually answered the question. I think it boils down to the info below

LitPro
$500
20hz Refresh Rate GPS

Crossbox
$285 USD (249 euro)
10hz Refresh Rate (This is old and not relevant, as of 2020 CrossBox created their own gps with 20hz, just like LitPro!) Also still at a great price of around $265.

I think the biggest Pro for LitPro is the hardware and refresh rate. 10hz is 10 data locations uploaded per second. LitPro uses 20hz which means 20 locations are updated per second. So technically speaking, the LitPro should be 2 times more accurate. So if you really want to see the exact line you took in a corner, you need the LitPro.

The biggest Pro for the Crossbox is price. You get the entire "kit" for $285. The GPS is currently on eBay for $135 with free shipping. But, Amazon reviews show there are chances of getting DOA device. Other reviews state that when it works they love it. So if you get a working device, hopefully you'll be set for awhile. The Crossbox app, for unlimited usage, is 179 euro or $207 usd. So you are getting some decent savings by purchasing the "kit" from Crossbox directly. The next pro for Crossbox is you can replace the hardware for $135. I'm not sure what the warranty is on a LitPro but I'm sure it expires sometime, and if it fails you will need to fork over another $500.

Here is another alternative:

MX Buddy
$140
App $3.99
GPS $135

You get just as good tracking as Crossbox at half the price. The App isn't nearly as in-depth with statistics and line choices as the other apps. But for the price, I'm sure a lower classed rider will pick up some speeds using lap times alone.

I'm not sure which is best for you. Do you NEED to know exactly which line you took on a given course? Like, the inner most inside line vs maybe a line 12 inches to the left or right of that rut? If you need to know that information, which I would think most Pro's and Pro-Ams would need, then go with LitPro. Does the C Class rider need this? No. I think you'll be fine knowing if you went high or low in a given turn. I would think MX Buddy route with the GPS sensor would be best for C and B riders. But I think if you are serious and want to turn this into something more than playing on the weekend, you need the LitPro.

hahaha thnx for the laugh

Anyway, it is kind of a serious question. I've seen guys in karts who were not able to do 3 consistent laps trying to analyze data from lambda sensors in their exhaust. That seemed overkill to me.

it seems like the ability to see which line you used is faster or slower seems a good help, but just wondering if spending this money would be better spend on following some lessons from an mx coach/trainer. At least i can imagine that your typical c rider will have a hard time getting through the same rut in the same time 3 times in a row due to lack of technique.

Hey kNew!

Could you explain to me why an update rate of 20Hz (compared to 10Hz) should lead to see the lines better on a track? It does not say that the positions are more accurate. It just says, that there are more positions in between recorded. So, if you have 10 per second, you have approx. 40 positions through a corner if it takes 4 seconds. This is more than enough to check which line the rider chose. As I mentioned before, tests have shown that lap times are not more accurate with a higher amount of update rates. Actually, in my opinion, you have more cons then pros when recording the motos with such high update rate, because the data size gets very big and it takes more than twice as long to sync the gps with your phone after the moto.

The XGPS160 comes with a 1 year warranty. So if the device doesn`t work, just ship it back and get a new one. By the way, we are selling a big amount of devices each week, we also test them before sending them out, and I can say that we are more than happy with the quality - approx. 1 out of 200 devices is defect., so thats pretty normal for electronical devices.

Motocross is a racing sport. Every rider, C level, B or A, wants to perform good on the track - let`s be serious - it makes much more fun if you are good at what you do. If you use a GPS lap timer every time you ride you will get a very good feeling about which technique leads to faster lap times. If you try out a different technique like:

> braking earlier but accelerating earlier
> ride smoother
> take more momentum through the corner
> try corners with higher gears

How do you know if a technique works better for you if you never analyse your motos afterwards?

I am a sport scientist and I am always wondering about 90% of the mx-riders. In so many other sports the athletes understand that analysing is key to improve fast. In motocross most of the riders think that just riding laps will make you faster. Well, it does, but , if you would analyse your laps you could have twice as much progress in the same time. How will you ever now if what you did on the track makes sense or not.

So in my point of view, yes, a lap anaysing tool like CrossBox or Litpro should be used by every athlete that wants to improve their riding skills.I think it is just a question of time, until EVERY motocross rider uses a tool like this.

Pair the mxbuddy with a gopro and youll know exactly where you went..

Unfortunately since last year you are not allowed to use an action cam anymore (at least over here). Insurance issue.

I understand the math Nino is using really well: interpolating between points to fill in the blanks on the 10hz data. There are a lot of reasons we choose 20hz over 10hz (brake points, acceleration points, take-offs, landings, bouncing on the landings, rounding out corners, corner apexes, etc). You can do all of that with interpolation math, but it's not as good. Obviously we have the choice since we designed and built our own hardware and firmware and we are sticking to 20hz.

Right now though it isn't that our customers aren't sure if they need 20hz or 10hz or 1hz its that they don't know how fun lap times are to ride with. Everyone thinks its only pro racing teams that need lap times and the best thing that could happen as a result of this thread is that you just get a taste for how fun it is to ride with lap times. It's a whole other way to enjoy the sport that makes on-the-bike time more fun and purposeful, as well as all the enjoyment you'll get once you are back at the office. Give it a shot

If that offer still stands, I’m a lock at fifty off. I’ve been riding with a polar watch and an H7 HRM for a few years...

I’ve been riding with a polar watch and an H7 HRM for a few years. Probably two years ago I missed an email or ad or something from lit pro for a Black Friday sale and tried to buy Monday or tuesday but it was back to msrp. I kick myself to this day for that.

Sent you a DM @DTR830. And yes, you can purchase extras, but when you buy, just mention in the comments how many helmets you rotate between and we can make sure you are covered. Thanks

Another option is buying 3M Dual Lock. That’s the route I went.

Hi. I am Chris, the developer of MX Buddy. First of all, all mentioned systems were developed by absolute enthusiasts of the sport! I know Richard (LITPro) and Nino (CrossBox) are riding motocross themselves and I also use every free minute to sit on the bike!

I own a LITPro and an XGPS160 (CrossBox) as well and I’d like to give a brief overview of all the three solutions and what to expect from them. I try to be as unbiased as possible Wink

MX Buddy
+ Works with all GPS devices paired with your iPhone
+ GPS precision as good as the used GPS device delivers
+ XGPS160 direct download
+ GPS files import (e.g. exported from Polar, Garmin, etc.)
+ Lap times import from LITPro and MYLAPS
+ Calculates lap and segment times
+ Calculates theoretical best lap time (based on best segments)
+ Live display (best for a bar pad mount)
+ Siri speaks lap times and segment infos
+ Extensive bike setups assigned to tracks and conditions
+ Heart rate recording (needs a heart rate belt)
+ Works without internet connection
+ No user account needed
+ Displays laps and segments on a zoomable map with color coded speeds
(Lap navigation with time line, speeds and lap comparison will be available with v2.16)

CrossBox
+ Most features mentioned above
+ Operates with XGPS160
+ Lap navigation with timeline
+ Lap comparison on a map
+ Compare riding sessions with other riders
- No heart rate
- No zooming in on maps

LITPro
+ Most features mentioned above
+ Hardware and software explicitly designed for motocross
+ 20Hz GPS fused with other sensor data (gyro and accelerometer)
+ Cornering analysis (with theoretical best lap time)
+ Jump analysis
+ Start analysis
+ Acceleration and decceleration analysis
+ High definition maps
+ Very sturdy and waterproof
+ Extensive live timing for riders and trainers with communication
+ SAFERIDE™
+ Has been used and accepted as a training device by professional riders and trainers for years
- needs internet connection
- slower sync than with XGPS160 (has more data points to transfer)


Each of the three solutions was developed with the aim of providing an optimal solution for motocross riders and coaches, using three different approaches with different hardware, software and pricing. It's your choice Wink

I am 53 in a couple of months, I classify myself as a slow vet that loves riding his Dirt Bike. As I have mentioned before I have had LITPRO from day one. I am sure it has helped my lap times, but the real benefit I get is looking at my laps and times after I have been riding. I now have nearly 3 years of information on all the tracks I have ridden on it is enjoyable looking back at these tracks I have been to. Wether it is 100mph top speed at a beach race here in NZ or 1 slow lap on the main track at Glen Helen before heading back to the REM track.

I hope your countryman with the bad accident at GH is doing well. To be honest I haven't paid much attention to all this until this thread, I actually thought these were action cams. Unsure To have company developers and owners on here is really outstanding, but some of this stuff is way too techie for me. It's great to have options, and it is now on my to do list. I spoke to another rider today that said the same thing. Thanks everyone for the input.

Looks like whoever develops an Android app first will get my money...
