I have soldered such a device by myself and it works. I think the phone needs only a little more than 120mA for charging, depending on which features are powered on (GSM, Bluetooth, WiFI, GPS etc). The main problem that I see is, that the FR will not recognize the load it may pull from the USB line if you don't put that magic resistor between the Id and GND pin of the USB plug. You can also use the power_center tool to force a charge of 500mA, but I believe it falls back to 100mA as soon as the power supply drops (what will happen if you stop bycicling). So a battery-buffered solution would be preferable. BTW: Could you please send a link to the shop where you found this DC converter?
