This is an iPhone bike mount that does more than just hold the phone in place on the handlebars. The LiveRider has two killer advantages that make it stand out from the crowd, for not only does it protect the phone, whilst making the screen accessible to the rider it also records the riders performance like a bike computer, and it also does this without the faff of connecting the sensor to the handlebar with wires.
The iPhone app comes included and turns the phone into a bike 'computer'
The wireless connectivity part is cool as it makes it so much simpler to install, rather than having to route the wires from the rear wheel and securing it along the tubes of the bike. It works on 2.4 GHz radio frequency, (as do cordless phones) and the sensor is a self-contained battery powered unit that connects wirelessly to the iPhone bike holder, which connects to the iPhone through the 30 pin charging port.
This unit sends the wheel speed and pedal cadence to the iPhone handlebar mount
As the package includes the mount, sensor and an app. there are many possibilities for improving your performance or just recording your rides. One I particularly liked is the ability to see how you are doing compared to previous occasions on the same route. You can tell whether you are behind or ahead of schedule as your progress is therefore monitored.
While the holder protects the phone you would need to remove it from an existing iPhone 4 case, but I notice that the receiving unit is separate from the holder so in theory you could attach the receiver to your your phone and just pop it in your pocket while riding. You wouldn’t be able to read the speedo etc. but you would be recording your route.
