LIGHT UP YOUR RIDE.
An E-MTB weighing just 15.5kg. Yup, you read that right. The Scott Lumen takes the world's fastest XC/trail frame platform and adds completely silent and powerful electric assistance all while maintaining Scott's legendary lightweight DNA.
Compact Powerful Assistance
From the beginning, the Scott's objective was to create the lightest possible E-Bike and, after much investigation, it was clear that the TQ HPR50 was the ultimate solution for the Scott eRIDE R&D Team to achieve their goals.
TQ is a German company founded in 1994 who specialize in electric components across a range of industries including aerospace, medical and infrastructure. With the HPR50, they simply rewrote the rules, delivering an unprecedented weight/power ratio of 1.8 kg for 50Nm. With a diameter of 8 cm, TQ has innovated by using a harmonic gear system.
This allows for a reduction of size, while also increasing the accuracy of the system. This results in a lighter bike, better integration, while reducing backlash for a more natural pedalling sensation. This technology also allows for the reduction in system noise for a truly natural experience.
After all, you are in the outdoors to, well, enjoy the outdoors.
ALWAYS CONNECTED
To maintain a clean cockpit, the TQ system puts the focus on a minimalistic display located in the top tube paired to a discrete shifter on the handlebar.
At a glance, the LED display provides all the essential info, such as the battery level %, remaining KM range and even Watts, thanks to an integrated power meter.
Want more? Link up your phone and dive deep using the TQ E-Bike app, available through the Apple App or Google Play Store.
With an automatic Bluetooth connection, you can track your ride and customize your modes. Want to use it with a bike computer? That’s no problem too. Utilizing the built in ANT+, the system easily connects with a bike computer such as a Garmin, Hammerhead or Wahoo unit.
BATTERY
The Lumen features a 360Wh internal battery which can be further complemented by a 160Wh external range extender. Easily fixed to the front water bottle mount with Scott's uniquely designed quick release mount, the range extender features a slim design and low weight, meaning minimal impact on the bike’s handling.
SCOTT LUMEN GEOMETRY & FRAME DESIGN
Taking inspiration from the Spark, the objective was a riding position that feels just like a regular bike. We wanted the ability to descend like a trail bike without sacrificing anything when you need to put the hammer down, and a trail bike that can fly up the hill to do it all again on the next descent.
The TQ motor allows us to keep a standard Q-factor with a 55mm chain line – exactly the same as the Spark. This allows us to do a few interesting things. Firstly, we can guarantee great tire clearance while not sacrificing stiffness – which is key when it comes to power transfer.
Secondly, it gives you the exact same rider stance and pedal width as on a regular bike. And if you prefer a more aggressive ride, the head angle of the Lumen can be easily adjusted through one of 3 positions.
The geometry chart is based around the head angle of 65.5 degrees. Our adjustable headset cups allow for a steeper or slacker angle by .6 degrees in either direction. This can be done without cutting cables or bleeding brakes. All you do is disassemble the bar, rotate the headset cups 180 degrees, and reassemble.
Integrated Suspension Technology
The Spark debuted a frame platform with an integrated shock and the Lumen follows the same principle. Why integrated you ask? Well for one, it looks fantastic. But if we take a deeper look, this approach allowed Scott to refine suspension characteristics without sacrificing weight.
And when developing the world’s lightest e-MTB, every gram matters.
For the optimal performance of a suspension shock, power transfer must be the most direct possible. What Scott wanted to avoid are any inefficient directional movements, in other words, lateral movements (sideways to the direction of travel) as the shock goes through its compression.
Having an integrated shock allows us to improve this in several ways.
Firstly, the frame construction around the shock and with the trunnion mount can be designed to be much more rigid, reducing movement and fostering more efficient power transfer. Scott could also add much larger bearings to the seat tube pivot, further reinforcing this area and reducing any unnecessary motion.
While these may seem like minor improvements individually, the sum of their parts results in more efficient shock performance. Additionally, the shock is fully protected from any foreign elements. Rainy muddy ride? No problem, your shock will continue to perform at its best regardless.
Our integrated suspension technology also helps us to engineer frames with a lower shock placement which lowers centre of gravity. As a result, the bike benefits from better handling, and a more stable, confidence inspiring ride for you.
