Remember the trend to say "time-shift" rather than "record" when it came to recording TV shows for later viewing? I suggest replacing "commuting" with "geo-shifting" such as, "I geo-shifted by bike this morning". Other ideas: pedal-estrianated, pedal-pushed, velocipedalled, veloci-raftered, zipped, spoked, spun, salmoned (well, that's a no-no) ninja-ed (also a no-no) bicycled, "two-wheeled it", "reduced my carbon ass-print", "circus-bear'ed it", cranked, cranked-it, cadence-managed, velocentrized, velo-muted, propelled-myself, HPV'd it (sorry purists), "gave the finger to the oil companies", "refused to join the auto-centric scrum", Pee-Wee'd it, vele-ported, "fahrrad-ed it", "fahrradinated", "beat traffic" and "enjoyed my ride".
