It's been more than 6 months that i am using firefox roadrunner pro d plus. It is a very good bike if you are starting with cycling. It is perfect for city use. Can go very fast on flats as well as comfortable enough on gravel and bad road.
The suspension lockout feature is really good.
Overall a really good bike
Smooth city riding experience and no complaints after 5 months of regular usage.
Best bike in the segment.
Best in this range. If u like long journey take this bike.
It's lightweight and smooth gear shifting is the best
