Ever wondered how fast a mountain bike could actually go (when towed by a motorbike)? Well, German pro mountain biker, Elias Schwärzler, set out to answer this question and set a Guinness World Record speed of an incredible 272.9kph (169mph) in the process
That's pretty fast by any measure and Elias' video released this week gives you a sense of what it's like to go that fast on a mountain bike – because obviously, we don't recommend you try this yourself.
What's most amazing about the record attempt is that Elias didn't use any special components on his bike, every component is a standard off-the-shell part that anyone could buy. He choose his Scott Gambler downhill bike and as far as we can see the bike hasn't even been altered much from its standard downhill spec. There have been a couple of little changes though, Elias ran a single crown fork rather than a dual crown model, the drivetrain was set to single-speed, and some less knobbly tires fitted.
Tires are obviously the most important spec choice as mountain bike tires aren't really designed to travel 272kph. Elias says on his Instagram (opens in new tab) that he tested dozens of tires of a custom-built dyno before settling on Continental Race King's. Tire pressure was also an important consideration and he ran Tubolito tubes pumped up to roughly 60psi, or 4 Bar.
