New bikes.

A new Web site.

And a second location.

"We have a lot of exciting stuff going on," said Tom Demagall, co-owner with his wife Britt of Golden Triangle Bike Rentals, Downtown. Their business is in a small one-story building sandwiched between the PNC Building and First Avenue Garage, a short block from the Municipal Courts Building. It's open from 11 a.m. to 8 p.m. Tuesday through Friday and from 10 a.m. to 8 p.m. Saturday and Sunday.

Demagall, 35, of Wilkins Township, said his wife left her full-time job as a social worker in late May to open their new bike rental site at the South Side Works. It's in front of the Cheesecake Factory on 27th Street, two blocks from Carson Street. It's open from 11 a.m. to 7 p.m. Thursday through Sunday.

"We've been pleased at the response at the new location," he said. "She's been busy over there."

Demagall said his father, also Tom, a recently retired salesman, has been helping out in several capacities. He's an advisor, accountant and bike-assembler. "He puts the bikes together at his home in Mount Pleasant and brings them in to the shop," Demagall said. "It's enabled me to make better use of my time."

A group of walkers waved and said hello to Demagall as they passed by the shop. "They're regular customers," he said. "They work next door at PNC and they alternate walking and riding."

This is Demagall's third year in business. He took over from Peggy Krall.

"She was very helpful during the transition," he said. "She gave me the phone number and the Web site. I also bought roller blades and a bike or two from her. She was very cooperative. She wanted to see the business succeed."

Demagall rents bikes for $8 an hour or $30 a day. The rate is $5 an hour on Thursday. There are group rates and 15 percent discounts on the Web site. He also rents child trailers and tag-a-longs. He hands out rider-friendly maps so customers can easily find their way as they bike up and down the three rivers.

Weekends continue to be his busiest time, "thanks to all the families who come down to ride." An extended family that was staying at the Marriott reserved 25 bikes last Saturday. "They rode all along the rivers, had lunch at the Hofbrau House on the South Side and had a wonderful time.

"The enthusiasm for the trails seems to be at an all-time high," he said.

"I don't think I ever truly realized what a treasure we have here in our bike trail system."

He said that point was pedaled home recently during a conversation with some residents of Portland, Ore., a known bike-friendly city.

He congratulated them on their bike lanes and bike-commuting options, and they praised the quality of the recreational trails in and around Pittsburgh.

Their comments "gave me a whole new sense of pride and enthusiasm for what we have," he said.

Allison Thompson and her son, Christopher Bangs, 17, both of Squirrel Hill, took advantage of the $5 an hour Thursday special last week. "These are very comfortable bikes," she said. "We really like them." She and her daughter, Emma, 15, took them for a test ride last month.

Mike Lloyd, 48, an attorney from Upper St. Clair, where he is executive director of the YMCA, said he alternates biking and running during his lunch hours. "It's so easy to get on the trail, and Tom and Britt do a great job. We're lucky to have them here."
