Cycling GPS units have a habit of dying if you’re doing much more than the usual Sunday morning run, back for lunch. But the new Shanren Discovery GPS has a claimed battery life of 96 hours, so you should be able to take on multi-day rides without needing to recharge.

You’d expect a GPS with that sort of battery life to be a monster. The Shanren Discovery unit is a bit chunkier than a Garmin, but at 137g it’s not too bulky and it way outlasts Garmin’s maximum 15 to 20 hour battery life in its units. The screen is 6.8cm wide and displays 28 data fields. It’s controlled via three buttons on the top of the GPS.

Shanren has its own click-in mounting system and makes a special out front mount to support the unit. This has two clamps, to sit on either side of the stem’s faceplate and hold the unit firmly in place, with less chance if it slipping down when you hit a bump. There’s also a chainstay mounted speed/cadence sensor available.

Shanren’s Indiegogo campaign is almost 400% overfunded, so there are clearly plenty of people out there looking to invest in a GPS with legs. Units are planned to ship from April, with a full package currently priced from $179 against a post-launch price of $308. For more details, take a look at Shanren’s Indigogo page.

We’ve got a unit in for test at the moment, so look out for a review soon. We’d like to be able to say that we’ve verified the battery life claim – but with the rotten weather at present, it’s going to take a while to hit 96 hours’ riding.
