It is massive!
i have lost 75lbs. That is modest by some standards, but 1/3 of my pre-bypass body weight. Two things re riding:
On my Royal Enfield, max capacity 170kg, my partner and I can both go on it together, but before we were combined a bit heavy!
On my Triumph Bonneville, which we use for longer trips with my wife pillion, it used to cause her pain in the tendons at the top of her thighs. Now - not at all. She worked out - she needn’t spread her legs so far apart to get her knees either side of my backside!!!
Generally - I am fitter, stronger, healthier. I am walking uphill, climbing stairs, lifting weights a bit - I feel the difference as I fling the bike around.....
