Stealth electric road bike shares features with the Addict endurance bike

Scott has launched the new Fastlane electric road bike, with the Premium spec dropping the claimed weight under 10kg.

The new bike shares its geometry and some components with the non-assisted Scott Addict endurance bike (the non-RC version) and is made of the same HMX carbon fibre as top specs of that bike. There are three Fastlane specs at launch, with prices of £6,399, £7,299 and £11,099.

The Fastlane is built around the TQ HPR40 ebike motor system, which has enabled Scott to produce a stealth ebike with a slimline profile that’s not that different from a pedal-powered bike.

Scott claims an 865g frame weight for the HMX carbon frame, with the fork adding 353g, both comparable weights to a non-assisted performance race bike. Scott says the aero tube profiles help to extend the battery range.

Wide tyres are now pretty much standard on new road bikes and the Fastlane is equipped with 34mm tyres, which Scott says enable you to take on a range of surfaces. There's clearance to go as wide as 38mm, the same as the Addict.

The Fastlane has an integrated rear light, powered by the main battery, and the option to connect a front light to the battery, too. As with the Addict, bolts under the front of the top tube enable you to add a Syncros frame bag. 

TQ’s lightest, most compact motor

The TQ HPR40 motor is claimed to provide assistance comparable to a gentle push on the back.

TQ offers three motors: the HPR40, HPR50 and HPR60, with their suffixes denoting their torque output. Scott has chosen to use the lowest-torque HPR40 motor for the Fastlane, which is also the most compact and has a 200W power output, rather than the larger motors’ 300W and 350W respectively. 

The TQ HPR40 motor’s claimed weight is 1.17kg and Scott compares its assistance to a gentle push on the back. It’s also claimed to be quieter and to incorporate software that enables it to learn from the rider’s style and adapt to their assistance needs.

The display unit integrates into a bar end.

The controls are also slimline, with the three assist levels selected via the third button on the Shimano Di2 shifters and a display unit that replaces a bar-end plug, and shows the battery charge and the assistance mode. 

Scott has chosen TQ’s mid-capacity 290Wh down-tube integrated battery with a 1.46kg claimed weight, so the motor plus battery contribute only 2.63kg of the Fastlane's total weight.

Despite the stealth implementation, the HPR40’s battery can still power lights and other peripheral electronics. The TQ system can also be paired with a cycling computer via ANT+ to provide a wider display of motor stats.

The HPR40 is the same TQ motor unit as used by Canyon in its Endurace:ONfly electric bike, which also boasts a sub-10kg weight in its top spec and which we rode at its launch event in Girona.

Scott Fastlane spec details

There are three versions of the Fastlane, with prices starting at £6,399.

Scott is offering the Fastlane in three specs: Premium, 10 and 20.

It equips the Fastlane Premium and 10 specs with a one-piece Syncros carbon bar/stem, with an integrated Torq tool, which enables you to fettle all the bolts on the bike.
