Tim Brummer, co-designer of the record-setting White Lightning, described the design and construction of the Lightning X2, his faired recumbent bicycle that won the speed trials for bicycles this year. A full Kevlar fairing was made using a plaster male and fiberglass female mold. The 17-kg (38-lbm) vehicle has a clever trap door for foot launches and an easy-opening shell. Tim recommends a 1115-mm (44-inch) wheelbase for recumbent bicycles.
