Thanks a lot, been looking for something like this for a while, going to try it out!

For those of you who don't want to search for it, here's the link to the app on Play Store.

The speed limit is 10.5 km/hr which is approximately equivalent to a 9:12 mile.

If you use a speedometer app to show your current pace, you can easily stay under that limit and hatch your eggs more quickly. Obviously, the trade-off is less intensive exercise.

Jogging mode? I'd be happy with a skateboard mode.

Thread dead

For those interested, I found a third-party solution. Seems pretty slick. Upper limited for POGO is 6.5mph \ ~10.5kph fyi

I use https://play.google.com/store/apps/details?id=de.zuim.speedoverlay to re-calibrate my speed from time to time. If you just want a warning (tone/buzz/..) whenever you exceed the limit, there are a few speed warning apps.

I can ride my bike and get 100% distance tracked. The key is NEVER going over the 10.5km limit or less than 175 meters every minute. The second you go over the distance the majority of the distance tracked for that minute is gone.

I would recommend this App from the Google Play store to have a small Odometer that can overlay on top of your game while you ride. Always keep yourself under 11 km and you will be fine. Try and ride in straight lines for best results.

My jogger medal is currently at 2600km tracked in the game and a lot of this has come from riding over the course of the summer and fall until snow hit the ground.

It's difficult to keep yourself riding so slowly, it's very unnatural on a bike. Remember to set your GPS accuracy to it's highest accuracy settings. Hopefully with the Overlay you will have some more successful results.

This is the one I use. It lets you adjust the positioning, size, transparency, as well as units to either km, miles, or m/s(meters per second). Works well with the game and keeps me under the tracking limit so I can get all of my distance logged.

If you're an Android player then use this: Speed Overlay

It will show you the same speed as PoGO is registering, as the same GPS signal broadcasts to both apps. Keep the speed under 10kmh :)

Just so you know you don't need this added to the game as there is an app you can get right now that will overlay onto pogo and show your speed. Its called Speed Overlay here is a link. https://play.google.com/store/apps/details?id=de.zuim.speedoverlay

In PoGo you'd get ha big red banner telling you you don't have GPS reception. Without it the game doesn't know where to truthfully position you on the map and so it doesn' fill it with game stuff. The position shown is likely the last one from whennthe game had a GPS position.

Unfortunately checking you have GPS reception with some other app doesn't fix this without actually restarting the game too. This shouldn't be necessary of course and the map should be filled as soon as a GPS lock has become available. It is yet another bug that needs fixing.

On Android you could use this Speed Overlay app. It would most likely show "No GPS".

Your assumption that a 26" tire has an outer circumference you can compute from that measure is flawed. Depending on the exact type of tire, the circumference can vary from 1990mm to 2100mm (see e.g. https://www.raederwerft.de/index.php?code=1042802).

To properly calibrate your speed use software and GPS, e.g. Speed Overlay on android: https://play.google.com/store/apps/details?id=de.zuim.speedoverlay although you could just use a measuring tape or a piece of rope.

I find 10km/h is only a challenge because it gets boring quickly.

I did the same with a belt clip holster, however, I screwed a universal bottle mount clamp to it after removing the belt clip part and drilling holes in it.

If you do this, make sure to mount the clip in such a way the flashlight and camera aren't covered up. The flashlight has come in handy as a backup head light more than a few times.

Though I don't manually catch while riding (GO+) I do spin stops, and most importantly run the Speed Overlay app to keep my speed at 10k per hour for egg hatching.

Best phone mount I've ever owned - and I've been through quite a few. Bumps, dirt, train tracks - I've never had an issue dropping a phone with this setup.

Added> best bicycle for PoGo are big heavy cruisers, old three speeds, and small wheel folders where they typically ride a little slower. 10Kph is pretty slow, but a good heavy bike which promotes a more upright posture works amazingly well.

I slowbike in a straight line as much as possible, I use a GPS speed overlay app (https://play.google.com/store/apps/details?id=de.zuim.speedoverlay&hl=nl) to make sure I'm going 10,5 km/h and have my ipod with a audiobook on it with me to listen to. The audiobook makes it less boring for me!

Wow can you link that? Or is it literally called speed overlay?

Edit: here it is https://play.google.com/store/apps/details?id=de.zuim.speedoverlay

Link for the lazy

I use this: SpeedOverlay

Don't know if it can alert acoustically, but I've used Speed Overlay on android for a while to learn how slow 10.5 km/h actually is: https://play.google.com/store/apps/details?id=de.zuim.speedoverlay

Its not the products fault that you will not get the distance from your rides. The product is a button with lights and vibration that can talk to the phone via bluetooth connection, the game and more importantly your phone is doing all the work. It tells it when to light up, what color and to add in the correct vibration. Your coordinates are all done on the phone and sent to the server every 4 minutes or so. If you are getting from point a to point b as the crow fly's faster than the speed limit they have for hatching eggs around 10.7mph, which btw is not the same thing as the "you are going to fast" message you get when in a moving vehicle like a car at around 18 to 20 mph.

What does that mean....travel at your own riding speed on a straight path and you are likely to want to throw the gottcha in the trash. Travel on a curvy path and you will get some of the distance but not all of it. Try to ride your bike under the speed limit and you can get just about all the distance recorded and look like a child learning how to ride a bike for the very first time because you can't balance it very good going that slow.

I don't know about IOS but Android has some overlay apps that can show you your distance travel speed in mph, in fact there may be an app on your phone already that can do this like google maps without an overlay feature. So if you have a nice phone mount on your bike you can run the game and have the overlay showing you how fast you are going according to gps on your phone. I don't think IOS allows for overlays so the app would have to display the speed while pokmon go was in the background which a nice feature that is one of the great reasons to own a gottcha or pogo+ anyway as it will save battery life while catching, spinning, and hatching. Or you can do what I finally did and say F it, I want to ride my bike for the speed and exhilarating feeling you get from coasting down a steep hill and not be troubled to constantly check what speed I am going. I decided to just get whatever I got and be happy with not only my ride but the game too. Hint if you don't look at the journal of your trips you will enjoy the rides you have a lot more.

I bought a cheap reflector that had a thick rubber band type clamp for a dollar then took the reflector off and put the rubber strap through the clip piece on the go+ then clip it on to the handle bars near the hand grip for easy access with my thumb. At first I tried to use the strap that came with the go+ but you have to fiddle to get it on and off this became very annoying when I wanted to chain my bike up at my destination. I also had a clip to hip hard case to place my phone into and rigged it to the handlebars as well but not to look at the screen as the go+ makes it much safer to just lock that screen I just put it there so I can hear some music while riding at a low volume so I can still hear everything going on around me. Know your route and exactly where the pokestops are on that route, in this way you can take a brief stop to get everything spawned and also collect the spins too. If not you will drive past many pokemon and many stops without collecting them. If you want egg distance you are gonna have to crawl at a snails pace to achieve the correct speed. I recommend you get the app called speedoverlay for android. There might be one for IOS but you would have to search for it. Basically this will use gps to track your speed per hour the same way the game does(which is total crap)and display it on a tiny overlay on the screen so you can maintain the right speed. Wear safety gear to help protect yourself, if you are riding on the road do not use the screen or the overlay as your not getting hit is more important than all the pokemon in all the pokemon games put together. Above all else.....Have fun!
