drawing pictures with GPS and a bike

This guy (wallygpx) turns on GPS tracking, gets on his bike and starts drawing – on Google Maps. His tools are his leg muscles, water bottle, his bike, and a smartphone with GPS tracking app.

He has a lot of drawings but here’s a few:

His site has many more but as he admits his site is pretty weird. It’s all Flash.

HOLUX GPSport 260 Pro second review


Like the first review, I did my first ride as a mountain ride with the HOLUX GPSport 260 Pro. I had some kinks to work out as I had not previously tested my mounting method. I did have issues as I mounted the unit on the bar, and not the stem. The GPS unit kept sliding around my bar every time I hit a bump. This was due to user error I must admit. At the time I did not realize the bracket was adaptable to both the bars and stem. Once I had remounted the GPS unit to the stem, I had no further problems regarding the mounting of the unit, or with the unit not staying put.

I tested HOLUX GPSport 260 Pro on some sections of tough singletrack trail in Sedona, Arizona. Aside from some user error from learning on the go, the unit did pretty well once I got the hang of the user interface. During this ride, I tried to use the unit with the speed sensor. Unfortunately, my bike’s chain stays are located too far from the wheel’s spokes to pick up the magnet and register the speed. However, I found the unit’s internal tracking to be sufficient and fairly accurate. If I had more time, I would have experimented to see if mounting the sensor on the front fork would have been sufficiently close to pick up the magnet. This is where I have mounted previous speed sensors before. The directions could be more informative in the mounting procedure regarding different bike types.

I also tested the heart rate monitor during my initial ride. The monitor worked quite well, but I found it to be quite hot after a couple of hours riding in the Arizona sun, and I shed it mid-ride. This isn’t unlike any other heart rate monitor I have worn before; it was just a warm day to have something around my chest. I felt that the unit worked well, and I was satisfied it was reporting accurately.

I wouldn’t recommend mounting the cadence sensor on a mountain bike, as the other reviewer stated. It is in a vulnerable spot on a mountain bike, the chainstay with the magnet on the crank arm. However, unless you are a road rider or serious cross country mountain bike racer, chances are that you don’t need to know your cadence. I think this position would be fine on a road bike, and the unit would be well-suited for the role.

I was surprised by the level of functionality of the unit. While riding, I used the unit in both plot and sport modes. I did find switching between the modes difficult to do while riding due to the sensitivity of the toggle button. Despite this however, the unit is quite capable. I was pleased to see how it plotted my track over the course of the 12 mile ride. When I compared it to Google Maps, which the software lets you do easily, the track was fairly accurate. Most of the error was induced by its point tracking every 6 seconds or so, and this was only noticed on switch backs or tight turns where the unit wasn’t tracking every data point. This is an acceptable error of course. I was quite pleased to see my plots of heart rate, elevation gain, distance, etc.

Overall, I found the software interface to be intuitive and functional. I liked how the tracks could be viewed easily in Google Earth. Since I lack any other GPS or GIS software on my computer, Google Earth is my primary tool.

In summary, HOLUX GPSport 260 Pro seems to be a good bang for the buck.

HOLUX GPSport 260 Pro field review


HOLUX GPSport 260 Pro Review

First off, this unit is decidedly made for road bikes, not mountain bikes. It will work for mountain riders, but it’s more risky. Since I am a mountain biker, I used it for my test ride (Desert Classic Trail in South Mountain park), and the GPS functioned quite well.

Two things make this unit unfriendly for mountain bikers

1)The mount to the stem and headset is built for a road bike frame (the piece is too narrow to fit on a wider mountain bike stem). You’ll have to get a different mount to place the GPS unit on the frame.
2)The location of the sensor on the pedal/chainstay is dangerous when going over rocky terrain and could easily break the GPS

Road cyclists should not have these concerns, though.

Holux GPSport 260 pro review


People at Holux just sent us the new GPSport 260pro. This is a multi function GPS device for many outdoor activities such as biking, running, hiking, etc. We could go on and on about its numerous features and setup screens but we need to be brief here. And if you’re really looking for certain feature you can always download the user manual and have a look.

But here are some of the highlights. The pro version that we have comes with a heart rate monitor that wraps around your chest, a speed sensor to read the speed from the wheel, cadence sensor, and connects all the pieces together 2.4G ANT+ wireless technology which is super low power.

The hardware itself is pretty sturdy. The buttons are easy to operate, screen is to read. GPSport 260 pro has a 1.5″ screen with nice light blueish back light. The rechargeable battery holds 1050mAh which should last you about 18 hours with the back light off. It has 4MB of internal memory which can hold up to 160K waypoints. It has a buzzer alarm that you can setup for certain things such as speed, distance, or heart rate.

That’s not all though. Device is IPX-7 waterproof, has a barometer for more accurate altimeter feature, an electronic e-compass, and supports multiple languages (took us a while to switch to English from Chinese).

There are numerous operating modes. In Sport mode it shows various screens displaying everything from time, distance, speed, cadence, heart rate, altitude, calories, etc. In plot mode you can view your track, show a graph speed vs distance, speed vs time, altitude vs distance, and altitude vs time. In follow course mode you can trace back a track you’ve saved or go to point you may have saved. In training mode you select various goals or ranges such as heart rate, cadence, time, etc. Other modes are the multiple finder, pedometer, e-compass, and history.

I know we haven’t covered every single feature but after a day of use we found the GPSport 260 to be very easy to use. It communicates with the wireless sensors without a problem, battery life is very decent, all the menus are easy to navigate. The only downside is the black and white screen with not so much resolution. We still would definitely recommend this device.

And finally: We’ll be giving away the Holux GPSport 260 pro to a lucky reader very soon. Keep following Navigadget.

Bryton Rider50


We just found out about a new GPS receiver mostly designed for cyclists. It is called Rider50 and will soon be offered by a Taiwanese company called Bryton.

The pricing is not announced yet but we’re pretty sure they looking Garmin Edge right in the eye as a competitor. More than anything Rider50 is a cycling computer as they’d like to call it that embeds a GPS receiver.

It has a 2.2″ TFT screen, IPX7 waterproof design, supports wireless data sharing with a technology called “Knock Knock” that utilizes 2.4GHz ANT+, and only weighs 106 grams.

Other specs are the micoSD card slot, rechargeable Li-Ion battery that can last up to 15 hours, mini USB interface, barometer, digital compass, and even preloaded detailed maps, and bike routes in certain countries.

We’ll let you know when we find a seller for the Bryton Rider50.

Trail Tech Voyager with GPS


What you’re looking at here is probably one of the few GPS devices specially designed for off road bikes. It is called Voyager and it is from Trail Tech. It is a really customized device for dirt bikes. For example it can read engine performance linked to GPS data and compare it against altitude to provide vital stats. It can track both ambient and engine temperature which saved in track data points and graphed for comparison with altitude changes.

It has a sunlight readable screen, a smart mount design that keeps it below the handlebars to protect it in case of crashes, waterproof design, 2.7″ screen, and connects to pretty much any AC/DC power from any kind of vehicle.

In addition utilizing GPS for your location Voyager also relies on other sensors such as ignition sensor, and wheel sensor to figure precisely when to stop/start tracking, etc.

You can upload OHV trails maps from ohvtrails.net which can be overlayed onto Google Earth and then uploaded to your device which has a memory card slot.

It costs $280 and does not sound like a bad investment.

Garmin buys MetriGear


Garmin just bought MetriGear, a Silicon Valley company that has created the pedal-based power solution for cycling for improving athletic performance in cycling and other sports.

Their product is the Vector which is a pedal-based power solution that integrates MetriGear’s custom force and motion sensor platform into the spindles of bicycle pedals to measure a cyclist’s performance. It even enables the independent measurement of pedal force for each leg.

It looks like the latest Edge 800 and Vector will be merged into a package soon, communicating using the ANT+ technology to track your speed, power, distance, time, elevation, calories burned and everything else in between.

No pricing or availability date information just yet. Stay tuned.
