I can ride a bike with no problem.
For swimming, i can survive in the water and can swim shorter distances, but not with the "proper" technique. Mainly can do the crawl using only my arms.
That "problem" blew up in my face in high school. The school had a pool meant for HS swimming meets, but that also meant that swimming was a part of the required PE course. The teacher saw i wasn't using the "proper" technique to swim so i was relegated to the shallow end of the pool where all the other students in the class were in the deep end getting more advanced lessons.
Bad enough on the humiliation factor alone, the there was a teachers aide there who obviously had no training nor experience in teaching swimming. All the instruction i received was to kick my legs up and down and i should move using only my legs, and that was enforced by requiring me to hold onto a flotation device with my arms so i couldn't swim with them. The teachers aide was told to have me swim 20 laps across the shallow end each day of class using only my legs with no further help. What happened was i push off the edge and got to the 1/4 lap mark that way and was unable to move any further no matter how much i kicked, so the humiliation grew even worse, and i was not given any useful advice to get me over this. Needless to say, i got a failing grade there.
For writing, i can write rather well if allowed to use block lettering and given sufficient time to do it. I could never do cursive well as it was a futile attempt to copy someone else's pretty writing style, and was always knocked for "poor penmanship", plus if forced to write fast, the quality drops very quickly in either style i used.
