I am enjoying my first couple of months on my new bike after not riding for literally decades!

I have a flat bar hybrid and am very happy with it. As I start to approach 15+ mile rides, I am considering options for more comfort and hand positions to avoid stiff wrists. Not looking for drop bar conversion.

Done a bit of research on old threads but figured a “bump” on the topic couldn’t hurt in case anyone has suggestions or experience with options that worked/not worked for them.

Any help appreciated, it you can include the brand/name that would be great.

Here is the bike, CTY 1.1
