High Gas Prices Pedal-Start Another Moped Revolution

5 essential Upgrades for Vintage Mopeds

* Photo: Todd Tankersley * X Prize, Schmex Prize. We've had a 100-mpg hybrid for more than 50 years. Far from the complicated gas/electric jobs hogging HOV lanes, this baby needs only one spark plug and maxes out at about 35 mph. Ladies and gentlemen, meet the moped. You've met before—the bike-cum-motorcycle was huge in the US during the 1973 oil crisis. And then, as the petroleum market stabilized, sales waned. But the latest spike in fuel prices has pedal-started a moped resurgence. "They're great on gas, and you can park them anywhere," says Daniel Kastner of 1977 Mopeds one of the few places pedheads can get new parts. For those who want to pedal some metal, a handful of originals survive — eBay!— and Slovenian manufacturer Tomos still makes new models. But it won't be the only game in town for long: Kastner is designing mopeds that ditch the old two-stroke engine for a cleaner four-stroke. They should hit the street next summer—albeit in the slow lane.
