David is in a hurry to get to Cheney Mansion where he is a scheduled presenter at its Green Sunday event today. Despite this he readily answers questions about the store and the many products he sells (actually, mostly rents). The store where David works is Greenline Wheels, near the Green Line el stop at 105 S. Marion in Oak Park. Before he leaves he shows us a gigantic pedal-powered three-wheeler with two seats that can be used with a child or physically challenged person. Several electric bikes are available as well as a host of large and small bicycles for almost any member of the family – all for rent by the hour or day. Outside the shop sits what we came to see: a four-passenger NEV, or Neighborhood Electric Vehicle. There are 5 of these vehicles available to rent, 3 four-passenger and 2 six passenger. While not legal for streets with speed limits over 30 mph, they can be driven around town, rain or shine, and are ideal for sightseeing. In fact, the store provides maps of Oak Park/River Forest highlighting a number of routes around town that showcase the many interesting homes and neighborhoods that visitors come from miles to see, as well as some of our adjacent cemeteries. Guided tours of the Frank Lloyd Wright historic district are also available with advance notice. For riders, helmets, child seats and trailers are available, and other items that might come in handy for visitors, such as souvenir water bottles and tee shirts can be purchased.
