scroll down to 1941. Is that for real? I can't believe anybody went that fast on a bike. I don't care if the guy was drafting the Blue Flame at Bonneville, is that speed possible?
even fasterDog

I think the record is around 166 mph now, drafting behind a modified rail dragster. Drafting makes a big difference.

October 10, 50 year old dutch rider Fred Rompelberg broke the world speed record (on a bicycle!) at the Bonneville Speedway in Utah.
His maximum speed was 268.612 km/hour.
The old record (245.077 km/hour) was held by John Howard (Texas, USA).

I do not know if this is true or possible, but it has been in Guiness since they started publishing back in the 70s. I guess it would take a while to "spin" that gear!

Getting that gear going would take a huge effort, if it could be done at all. The guys who try for the speed record are towed to a speed where they're able to turn the gear and then draft the tow car (usually some type of race car with a huge fairing to block the wind) to the highest speed they can attain. As noted in the other posts, 108mph is nothing.

That bike is currently displayed at Martin's Bike Shop in Ephrata, PA, along with a wide range of classic and historic bicycles. In addition to bike above, Martin's has every Schwinn Stingray, in original condition, those brought back some memories.

If you are ever in SE Pennsylvannia, stop by the shop and ask to see the museum. It's worth the trip.
gear inches neededDog

By my calculations, with a 27 inch wheel, it would take the equivalent of a 190 tooth chainring and 11 tooth cog at 120 crank rpms to go 166 mph, or 466 gear inches.
