It really depends on how important you think cycling is in your life. But it seems to me that that bike-date is in fact a "revelator": it reveals things about these guys that you wouldn't know otherwise. And you WANT to know these things... (the nipples-staring guy is a bit scary!)

Maybe some dating service in your area organizes activities for singles, including bike rides? These could be fun too. Or if you really want to meet a cyclist, maybe a bike club would be a good thing to join. From there maybe you can arrange with someone in particular to go for a ride at another moment, even just for fun.

Even if we don't consider ourselves to be incredible cyclists, we're still much more dedicated to the sport than the average person out there, and you're right that this can be intimidating. But if cycling is a really big part of your life, and if you feel it's closely linked to who you are, then your bike-date is probably a good technique to see right from the beginning how those guys will react to your passion in the long term...
