Fast, discreet, and naturally assisted, the Fastlane 20 Bike blends premium road feel with subtle e-bike power
What Our Gearhead® Experts Are Saying:
“I’d point the Fastlane 20 to riders who love the feel of a high-end road bike but want a little insurance for long days or big climbs. The TQ system is incredibly quiet and natural—it never feels like it’s riding for you. What really stands out is how normal it feels once the assist cuts off. If you’re e-curious but still want a true road ride, this bike nails that balance.”
We ride the Fastlane 20 Bike when we want to go far, go fast, and still feel like we earned it. Built by SCOTT, this sleek road machine hides its assist so well that it rides like a premium carbon bike first—and an e-bike second. Whether we’re stretching weekend mileage, smoothing out punchy climbs, or turning a long commute into something fun, the Fastlane keeps the ride feeling light, quiet, and unmistakably fast.
At the heart of the bike is the TQ HPR40 drive system, delivering gentle, almost invisible assistance that comes on smoothly when our legs ask for it and disappears just as cleanly when speeds pick up. Paired with a lightweight HMX carbon frame, Shimano 105 Di2 electronic shifting, and fast-rolling 700x34 tires, the Fastlane 20 feels composed and efficient across rolling terrain, long climbs, and fast group rides. It’s built for riders who want help—not a takeover—and performance that still feels earned.
