Turn your smartphone into a bike computer

This device uses your phone as a bike computer or to play music and does a lot more too.

It’s easy to end up with a lot of gadgets hooked up to your bike: lights, computer, bell. The Cobi smartphone mount is designed to dispense with these by integrating them all into one device to which you can also attach your smartphone to use as a bike computer.

The heart of the system is a smartphone mount which protects your phone on the bike while also charging it via its integrated battery pack, which can also be hooked up to a dynamo. There’s a water-resistant case which will take a smartphone with a screen up to 6 inches across and which is plugged into the base unit which is permanently mounted to the bike.

Paul started writing for Cycling Weekly in 2015, covering cycling tech, new bikes and product testing. Since then, he’s reviewed hundreds of bikes and thousands of other pieces of cycling equipment for the magazine and the Cycling Weekly website.

He’s been cycling for a lot longer than that though and his travels by bike have taken him all around Europe and to California. He’s been riding gravel since before gravel bikes existed too, riding a cyclocross bike through the Chilterns and along the South Downs.
