When you want to go on a bike ride and bring your iPod or mobile phone with you, but it has no power... do you reluctantly leave your device at home or do you delay your bike ride? Do you commute to work on your bike and want to charge a mobile device while you ride?
We (a few students at Columbia University) are developing a new product (tentatively called "iCharge") that attaches to your bike to harness the energy of wheel rotation to charge your mobile devices. We would appreciate if you can go to (link removed) and fill a 2-minute survey to share your preference on product development. Thanks a lot in advance!
The options we would like you to consider for the iCharge are:
A) Number of mobile devices (i.e. iPod, mobile phone, GPS) that can be charged at the same time: 1 or 2
B) Color: Black or Matches color of bike
C) Conventional cycling device such as front and back light, speedometer, odometer, rpm, cycling time
D) Weight: 1lb, 1.5lb, or 2lb
E) Price: $100, $150, or $200
