Yet the better noun for both, "bike", is now ambiguous.
The verbs "ride" and "bike" are a little better, as "ride" leans a little bit towards motorcycle, but not really. Not enough to be clear.
In any case, I rode my motorcycle to work today for the first time. I'm not sure it was any faster than bicycling to work (because I can go faster than traffic and break rules on my bicycle), but it sure was fun. I'm sure going home (which is 400 ft or so higher in elevation than work) will be faster by motorcycle, not having to pedal uphill in low gear.
Help me with wording! Qualifying each of these terms will drive me crazy.
