Mr. Hyde of Havertown may not be evil like Dr. Jekyll's alter ego, but he's just as unpredictable.

 Marty Hyde is a mild-mannered guy, but when he commutes to Garrettford Elementary School in Drexel Hill — 21/2  miles each way — he uses a different method of transit each day.

 One day he'll bike. Another day he'll rollerblade. More than anything, he loves to walk, which takes him about 90 minutes round-trip.

 But one thing is constant: He'll never drive to work. Although Hyde owns a Honda CR-V, he doesn't drive it unless he's with his family of four.

 "The price of gas seems to be going up, no one seems to be doing anything, and I'm just doing what I have always done,” said Hyde, 51, a music teacher.

 Growing up in Drexel Hill , Hyde said, he used to walk to elementary school. Later, as a student at Temple University , he would ride his bike.

 "Always I wanted to get there by my own steam,” he said. "I've just always believed in moving rather than being moved.”

 Walking is always his preference.

 "I know that I'm slower, but it's nice being the only person on my personal road,” he said. "I'm not sharing the road with anybody. I don't have to weave through traffic.”

 Besides his trip to work, his mountain bike comes in particularly handy for shopping. Hyde said he can fit two cases of beer in a wagon he attaches to his bike. People see him around the area walking, with his bike, or on his new toy, an Amish scooter, which has two big wheels.

 "He's kind of like an icon in the area,” said Denise Kennedy, 48, of Upper Darby , a secretary at the school. "People see him, you wave to him, there's Marty!”

 His attire is often hard to miss. When he walks to work on sunny days, he wears a big straw hat or a golf hat to keep the sun off his head and face. For rainy days, he has a lightweight, bright-yellow rainsuit complete with pants, jacket and a hood pulled tight.
