Scott Fastlane Premium Bike

The Scott Fastlane Premium Bike is an e-road bike — and Scott built it around the premise that those two words shouldn't require a compromise. The Fastlane is designed to look, handle, and feel like a high-end road bike that happens to have a motor inside it, not the other way around. Sub-10kg at 9.9 kilograms. HMX carbon throughout. Shimano Dura-Ace Di2. Zipp 353 NSW wheels. The assistance is real, the bike beneath it is serious, and the distinction between the two is almost imperceptible on the road.

The HMX carbon frame — Scott's highest-grade carbon construction — comes in at a claimed 865 grams with a 353-gram fork. That kind of frameset weight would be competitive in a standard road bike lineup; achieving it in an e-road bike required thoughtful integration at every level. The TQ HPR40 mid-drive motor sits at the bottom bracket in a housing that keeps the Fastlane's silhouette essentially identical to Scott's Addict road platform. At 1.17 kilograms and producing 40Nm of torque with 200 watts of assistance, the HPR40 is the motor of choice for riders who want the least intrusive boost available. It's German-engineered, whisper-quiet in operation, and the power delivery is smooth enough that the transition between assisted and unassisted pedaling at the US assist limit of 28mph doesn't interrupt the ride feel.

The 290Wh battery is fully internal — hidden inside the down tube with a flush-fitting charging port — and charges in approximately three hours. For riders who want to extend range, the frame is range extender ready: a 160Wh external unit can be added for longer efforts without modifying the bike. Three assist modes — Eco, Mid, and High — are selected via buttons on the hoods, and the TQ Bar-End-Display integrates into the handlebar ends like a bar plug, showing battery percentage and power mode without adding visual noise to the cockpit. Bluetooth and ANT+ connectivity allow pairing with TQ's dedicated smartphone app for more detailed ride data.

Scott built the Fastlane Premium with components that would justify the price on a non-assisted bike. Shimano Dura-Ace Di2 R9250 handles front and rear shifting electronically across a 12-speed drivetrain, with Dura-Ace R9270 hydraulic disc brakes at 160mm front and rear for stopping power that matches the bike's pace. The FSA e-Bike Carbon crankset runs 50/34T chainrings paired with a Shimano Dura-Ace R9200 11-34T cassette — a broad enough range to make full use of the assist system across varying terrain. Wheels are Zipp 353 NSW front and rear — Zipp's premium carbon clincher, chosen here for its combination of low weight, aerodynamic performance, and the ride quality that makes a 700x34 Schwalbe Pro One Evo tubeless tire feel fast rather than sluggish. The Syncros IC-R100-SL integrated bar and stem combo keeps cable routing clean and internal, preserving the bike's deliberately conventional silhouette.

Design Benefits

1. Sub-10kg e-road weight — At 9.9kg with a 290Wh battery and motor on board, the Fastlane Premium achieves a total weight that most conventional carbon road bikes would consider competitive. The HMX carbon frame and TQ HPR40 motor are the primary reasons.
2. TQ HPR40 — the right motor for road — The HPR40 is the lightest, most compact mid-drive motor in its class, engineered specifically for road and gravel bikes. 40Nm of torque, whisper-quiet operation, and smooth power delivery that doesn't announce itself at the pedals or through the drivetrain.
3. Fully internal, range-extender ready — The 290Wh battery disappears inside the frame, and the range extender compatibility means the Fastlane can be adapted for longer efforts without structural modification.
4. Flagship build spec throughout — Dura-Ace Di2, Zipp 353 NSW wheels, and a Syncros integrated cockpit are components chosen for performance, not to offset the cost of the motor system.
5. Rides like a road bike — The Fastlane's geometry, handling, and component selection are tuned to preserve the road bike experience. The assistance extends what you can do — it doesn't change how the bike behaves.

Final Take

The Fastlane Premium is for riders who want the range and recovery benefits of an e-road bike without giving up the ride character of a serious carbon machine. At 9.9kg with Dura-Ace Di2, Zipp 353 NSW, and the TQ HPR40's near-invisible assistance, it's the most honest answer to what an e-road bike should be — and one of the lightest production options available at any price.
