The Wunderlich gap bag for the U lock and rokstraps lives on the bike all the time. Wunderlich handlebar bag is ideal for the phone, vapestick (bit like lipstick, just hotter) and visor wipes. Plus I use an optimate USB adaptor from the 12V DIN socket and route the cables into the handlebar bag to charge everything up on the move. Handlebar bag goes on and off easy with velcro. Stop n go puncture kit lives under the pillion seat. Works well
The Wunderlich fairing bags are good for keeping stuff in as well, probably better for charging your phone, as they're static.
