My personal favorite is the 6thAnnual Philly Tweed Ride
A bicycle ride that incorporates a period theme, reminiscent of a 1950's car rally. Attracting over 100 riders the Philadelphia Tweed Ride theme is England from the 1900 to 1920 so the riders do wear a great deal of tweed. The Philadelphia Tweed Ride website is full of photo galleries from previous rides, many of the men and women look as if they have stepped off the fashion runways of that era. Many of the participants have vintage bicycles or bicycles that look vintage, along with modern bicycles as well.
Looking for something that you can take your children with you, then join Philadelphia Kidical Mass. Kidical Mass is a variation of Critical Mass, a group ride for families and their children through Philadelphia side streets and bike lanes. While using a mass of riders to create a safe cycling experience. This ride will be a one mile ride to the Philly Bike Expo.
Since its first year the Philly Bike Expo the attendees have braved blizzards and hurricanes to participate in its opening day and every year the number of vendors and attendees have grown. So much so that this year the have moved from their original home at the 23rd St. Armory to the Pennsylvania Convention Center. In addition to a very diverse collection of vendors in the exhibit hall there will be seminars books signings by Bike Snob NYC, planned rides and valet bike parking.
