Chris Mayhew, a cyclocross expert, and Mike Steidley, a champion stunt rider, will demonstrate their respective skills today at the Carnegie Science Center.
From noon to 2 p.m., Mayhew will review the basics of cyclocross, a type of competitive bicycling that requires riders to overcome various obstacles and barriers during a race. He will demonstrate skills used by cyclocross riders and also discuss training, clothing and safety.
Steidley, who has won several national championships and represented the United States in seven world championships, will maneuver his bike through a set of custom obstacles and ramps. His presentation will include free items for audience members.
The demonstrations will be held on the center's Bikes Plaza. The plaza borders the Three Rivers Heritage Trail behind the center. The outdoor programs are free with general admission.
From 11 a.m. to 3 p.m. today, Green Gears Pedicabs and Erie Insurance will offer center visitors free rides to various North Shore locations. Green Gears Pedicabs provides "emissions-free, people-powered transportation solutions around Pittsburgh."
Mayhew's and Steidley's presentations are part of BIKES: Science on Two Wheels, the center's popular display of all things bicycle. The history and science of bicycles is shown in interactive exhibits, demonstrations and bike-related activities of all kinds. More than 60 bikes from various eras are on display at the exhibit, thanks to contributing organizations.
Gala Work Day
Replacing a dilapidated bridge with a structurally engineered bridge, installing directional painted wands that correspond to the trail map on the Allegheny County website and erecting trail signs will be part of a "Gala Work Day" in Boyce Park Aug. 18.
The event, organized by the Pittsburgh Trails Advocacy Group, will begin at 9:30 a.m. with tool disbursement and a safety talk at the Cub 1 Pavilion. It's the first pavilion on the right after driving or biking through the main entrance from Center Road.
It's going to be different from a regular work day "in both size and scope," said Jim Kapp, PTAG's co-steward for Boyce Park. "It would be great if a few folks could bring a post hole digger, a digging bar, bow saws, loppers, cutting shears and a wheelbarrow."
The work will begin at 10 a.m.
Kapp said the Rivertown Brewery will provide food and drink for the work crews beginning at 1 p.m. He encouraged volunteers to bring their mountain bikes because "rides usually break out afterwards."
MAYA Bike Ride
The Second Pittsburgh Pedal Crawl, a unique series of rides to benefit families on both sides of the adoption equation, will be Sept. 15.
The event, hosted by MAYA, a local nonprofit organization, offers a 3/4-mile-long Family Fun Ride and rides of 10, 25 and 50 miles. The rides will begin and end where Highland Avenue enters Highland Park.
MAYA, which stands for Me And You At last, provides emotional and financial support to adoptive families, including those who adopt children and those whose children are being adopted.
The registration fee is $25 before Aug. 19; $30 afterward. Riders are encouraged to take a break from their pedaling to visit various businesses that will offer promotional discounts.
