Magnum ui5. White with blue logo, black battery, brown handlebar tips, and big brown wheels. Very distinctive. They also took the bright green ubolt lock...even though the bike didn't have a seat (I'd taken it off for "safekeeping").
Here's a pic! If you happen to see it (it's not common), I'd really really appreciate it! I've been prowling around the city...
