I think he's completely wrong, and it's HIS veiw that is too narrow. Go into any bike shop, look at any catalog, and you see tons of commuter bikes. Yup, the average Jane and Joe can get sexy bikes if they want them, but the utility commuter is everywhere!
Sexy bikes get all the press and hoopla, meanwhile there are several utility commuters in the "bottom" shelf of just about every brand.
I think he's just looking at the hoopla.
On my morning commute I see utility commuter bikes. Sometimes I see one guy who rides a recumbent. I'm pretty sure he's also commuting because he's got panniers and I see him so often.
In the afternoon I see commuter bikes and sometimes two guys on racers with Group Health jerseys going very fast. Not commuting. They would be the sexy bikes market share.
I think there's more hoopla in the sexy bike market niche, but greater numbers in the utility bike niche.
