Lightweight assisted performance comes together in the Fastlane 20 Bike with carbon construction and smooth mid-drive power

What Our Gearhead® Experts Are Saying:


“The Fastlane 20 stands out because it doesn’t feel like an e-bike unless you want it to. The motor engagement is extremely smooth, and the low drag makes it ride naturally once assist cuts off. The carbon frame and Di2 drivetrain keep things sharp and responsive, making it a strong option for riders who want subtle assistance without sacrificing road-bike performance.”


The Fastlane 20 Bike is engineered for riders who want assistance without compromising the feel of a high-performance road bike. Its HMX carbon frame is shaped around SCOTT’s endurance-focused geometry, delivering stability on long rides while maintaining an efficient, aerodynamic profile. The assist system is integrated so cleanly that the bike maintains a classic road silhouette, minimizing visual and weight penalties typically associated with e-bikes.


Power comes from the TQ HPR40 mid-drive system, which provides up to 40Nm of torque with exceptionally smooth engagement and near-zero drag when disengaged. This allows the bike to maintain a natural ride feel at speed while offering support on sustained climbs or late-ride fatigue. A 290Wh internal battery keeps overall weight low while delivering meaningful assistance for extended efforts.


The Fastlane 20 is equipped with Shimano 105 Di2 electronic shifting for precise gear changes, hydraulic disc brakes for consistent stopping power, and versatile carbon wheels paired with 700x34 tires for speed and comfort. It’s an ideal choice for endurance road riders, fitness-focused cyclists, and anyone looking to extend their range while preserving the performance and aesthetics of a premium road bike.
