Using a phone as a bike computer?

    I ride with a mobile on me as an emergency backup and re record gps data to log my rides (I don’t race, just like to track myself). I generally use my old Samsung S3 in a freezer bag for waterproofing. I’ve now been looking at bike computers like Garmin’s Edge Touring model with turn by turn navigation, think this would be handy to go find new routes, particularly on 50-100 mile rides. I’ve been thinking, why not combine the two? Less weight, less complexity etc etc. There are a few waterproof android phones about, some of them nice and small and some ruggedised so could be attached to the bar/stem in place of a bike computer, with one of the various apps providing bike computer duties, strava recording the ride in the background and Copilot or google maps providing directions. Was thinking about the Jeep Z6+ phone;

    This seems to be waterproof, has GPS, it’s ruggedised which may save it in a prang, has dual sim slots so I can use two PAYG sims to have the best chance of actually getting network in the event that I ever have to phone for a taxi/wife, and being a little 4 inch screen would fit nicely strapped over my stem.

    Problem is how to mount it to the bar/stem – no mount for this phone seems to exist, nor others particularly. Looks like there are various bar to phone mounts designed for motorbikes I could use however. The back plate appears to be screwed on to the device so I’m thinking I might epoxy a mounting plate to the back which I could then cable-tie to the stem.

    Anyone done this or found any useful workarounds?

    But if it is the end of the world and your gps isn’t accurate enough to warn, you might fall off the edge…

    I’m not sure if it has been mentioned but the Finn mount has cropped up a few times, I’ve no personal experience of it myself but it may be of interest to some.

    All depends on what you want to do and what your phone can do.

    I tried it with a Motorola
    I tried it with a Motorola Defy + (waterproof, Android 2.something)
    Too small and slow.

    A Sony Experia Z or THL T6 Pro (chinese waterproof Android) would work better and be a decent phone for day to day stuff.

    If you run in flight mode the battery lasts well.

    I used the Viewranger app to follow pre-made GPXs (exported form Strava routes)
    It was really good and the free version comes with OS Cycle Maps

    Also despite having a 4.3″ screen this is slightly smaller than the Jeep phone.

    Looks a good phone, though can’t see battery capacity. Also it’s larger, think I’d rather stick to 4 inch for a bike phone. Not using GLONASS shouldn’t be an issue, we got on fine without it before!

    +1 for the Quadlock universal mount. I ride with my iphone in a LifeProof waterproof case, works a treat!

    i use my old android phone
    i use my old android phone (htc one) without a sim card, on aeroplane mode strapped to my bars, and have my ‘proper’ phone in my jersey pocket with wifi hotspot turned on for data for maps etc.

    i’ve disabled all non-essential apps (email, weather etc.) and set the screen backlight to minimum.

    currently using strava to record rides mainly, and i also have an app called sports tracker which is pretty good as a bike computer – lots of stats over 5 screens. (duration, distance, current speed, average, energy, last mile speed, altitude, max speed)

    battery seems to last ages this way – approx 70% left after 4hrs

    i set it up a few weeks ago and have it secured pretty crudely at the moment in a cheap silicone case with a couple of holes cut in the back and small zip-ties attaching it to the stem – i can take the phone in and out easily if i stop, but probably need to look into a better solution as it’s not waterproof…

    sorry for the essay! :))

    I use a quad lock case and it’s slim enough to use as a day to day phone case.

    e.g. http://www.quadlockcase.com/products/universal-bike-mount-kit%5B/quote%5D

    Looks interesting, way overpriced for what it is though (just the mount – I won’t need a cover). I’ll probably mcgyver a gopro mount or similar to do the same thing.

    Edit: Actually having looked again the universal mount isn’t too expensive in the UK and looks quite an elegant solution. Also additional mounts available if I change phone later etc. Looks a good bet!

    The Garmin I was looking at was supposed to have 15 hours when using auto dimming, where the screen comes on only when there’s a turn coming up. I would think with a 2500mah battery you’d get about the same with the screen auto dimming, especially if it’s in airplane mode with all wireless units turned off and just GPS on.
