>>1075358Can't give you a definite answer, but I bet:
1. the word roadster was used for bikes like pic related -- back in the old days when the typical road bike hadn't been created yet
2. due to visual similarity the term roadster is a vague idea and is being re-used for townie bikes
3. Or it could just mean a townie-ish bike with slightly more aggressive riding position
The townie genre isn't clearly defined to begin with - where does townie end and beach cruiser begin - so it's hard to say for sure
