| May 22, 2014 at 16:01 | comment | added | Roaders | Thanks for the comments, Watts are measured using a Stages Power meter and the number correlate well with the powertap I used to have and the wattbike I use in the gym. so far the longest I have averaged 600W is only 55 seconds, I have a power goal of 600W for 1 minute. I can sustain an average of 285W for an hour but that is with traffic, lights ect. | |

| May 15, 2014 at 16:04 | comment | added | R. Chung | How are your watts being measured? And, the guy who claimed to be able to cruise at 30mph at 250 watts must not be riding a bike like yours -- that would imply very low rolling resistance and a CdA of around .145 m^2, which is lower than most unfaired recumbents and in the range of several faired recumbents. | |
| May 15, 2014 at 15:42 | comment | added | Daniel R Hicks | Weight affects the rolling resistance of the tires somewhat, especially if they're underinflated. But the wind resistance due to a wider body (and probably less "aero" posture) is much more significant than the actual weight per se. (And I agree that "cruising" at 30mph is doing pretty good already.) | |
