It’s 85 degrees outside and Ronny Jr. wants you to take him to the waterfront. Quick! You can either A) ignore him and keep preparing vegan potato curry for tomorrow’s Progressive Parents Potluck in the Park, B) pack the ol’ flask, smear sunscreen on Ronny while he plays make-simple-acts-10-times-harder and hightail it to some fountain for 20 minutes of look-at-me-I-can-splash, or C) gather the whole gang and head out for a sunny afternoon of family bike riding. But wait! Two adults and two kids biking together? How ever will it work? Most businesses only rent two-wheelers and tandems.

Cue Kerr Bikes (1020 SW Naito Parkway, 808-9955, kerrbikes.org), the nonprofit saint of unusual bike rentals, with options like the two-seater tricycle Deuce Coupe, the Model T-shaped Double Surrey (fits four—wink, wink), Chopper tricycle, go-kart-like Quad Sport and the adventurously named Slingshot, which reverses the usual tricycle-wheel configuration. And all proceeds benefit Albertina Kerr Centers, the Portland organization that supports children and families with developmental disabilities. Here’s to socially responsible afternoon-savers!
