Entry #157 & #158 ; revision as requested. No problem with adding color to design especially with a good reason/meaning.
Entry
#159; inverted color for colored background, I assume the color of bicycle is not only white. White lettering work on most colored background especially with the darker one.
For the lettering i've use Nexa Bold/Light, it's nice and free.
