Lightning Cycle Dynamics. 30 years ago young American rocket scientist Tim Brummer was an avid cyclist. However on longer rides he always experienced some pain and discomfort no matter what adjustments or saddles tried. Plus headwinds really took the enjoyment out of riding. Being an accomplished engineer, he set about designing a superior bike not encumbered by 100 year old racing rules. The result was the Lightning recumbent style bikes, whose performance is verified by dozens of world records and unmatched comfort recognized by thousands of owners world wide. The Brummer designed Lightning P-38 and R-84 models are hand built in the USA by experienced craftsmen, and custom made to order.
