We’ve all been there, driving down a one-lane street, backed up behind a cyclist that blocks our ambition of hitting the speed limit. Seriously, bikes limp along at 10 mph and hit what—30 mph—max? Well, no. How does 90 mph sound?

That’s right. Thanks to the engineering minds of Aerovelo and its bike, Eta, cyclists could theoretically complain about passing that big bead on your high performance vehicle.

Aerovelo Cofounders Cameron Robertson and Todd Reichert lead their team of University of Toronto (U of T) engineering students and alumni to design, simulate, optimize, build and pilot this escape pod-encased bike into the history books.

After breaking its own human-powered land speed record a few times over, this little tear drop settled on an impressive 144.17 kph (89.59 mph).

“It was a culmination of years of effort,” said Robertson. “There was a lot of excitement and relief that we have taken a good path and all the choices we made showed it could be done. With Eta’s design, we showed the range of improvement. In 2000 to 2015, there wasn’t much change to the [human-powered land] speed record. It incremented 10 mph in 15 years, from 73 to 83 mph. The rate of technological change was small; it was incremental improvements. In the span of two years with Eta, however, we incremented [the record] by 6.5 mph.”
