Bike speedo
 

Anyone try bike speedo I see it’s new looks nice. Bit windy for suits today.
Cheers

Yup, I bike in a speedo all the time in the summer. Once it gets to the mid-80s, ride in a tank top in a speedo. It helps out with the tan as well!!!

Used to bike in a speedo occasionally and short lightweight running shorts often. Felt great to be wearing so little when I was biking. However, I got saddle sores and chafing on my inner thighs so I switched to regular bike shorts.
I do usually ride shirtless when the temperature is above 70 so I do feel the sun and breeze above the waist.

Wear a speedo then get something like this to help add some cushion. Some of the speedos I bike in are smaller than this insert.
But I've been able to tuck it in without any issues and still have a comfortable ride.

I got a gel seat cover instead. Stopped the saddle sores but didn't help with the chafing.

For me it's Lycra cycle shorts on the bike and speedos or a swim thong on the beach.
I feel that each activity has it's own optimal clothing style, I used to run in short split sided shorts and a vest. I hated the coming of universal baggy knee length shorts for everything or the almost compulsory wearing of jeans at all times.

A lot of runners skip the shirt.
