SCOTT E-Contessa Genius 720 Bike

Boost is a hub and drivetrain standard developed by SRAM. Boost is built around a wider rear and front hub and enables stiffer wheels due to a wider spoke bracing angle. Boost 148 rear hubs move each flange of the rear hub three millimeters wider.

Boost is designed as a complete system so drivetrain performance isn’t compromised. Even though Boost pushes the cogs three millimeters outboard, the crankarm Q-Factor remains the same as the Boost system’s crankset utilizes front chainrings that sit a corresponding 3mm outward to ensure the required chainline. Boost cranks can onlybe used when paired with a 148mm hub. On the front the hub spacing is increased by 10mm to 110mm. Increased wheel stiffness and greater clearance for bigger tires are the main advantages of Boost technology. On our bikes, we wanted to go beyond the basics and reap all the benefits of this innovation by optimizing frame design and geometry.The 3 mm outboard chain ring adds clearance in the chain stay area that allows a substantial increase of the chain stay tube cross-section. Correspondingly,the stiffness in this part of the frame improves. Also, with a wider range of positions for the rear wheel, the frame geometry can be adjusted. We can shorten the chainstays for more agile handling.

To meet MTB specific needs, the E-8000 series was designed with all day performance in mind. The capacity of the Ion-Lithium battery has been increased to 500WH and can now be recharged in only 5 hours. The new design features a lower profile specifically for mountain bikes which improves both impact and vibration resistance.

The battery pack offers:

• 36V of nominal voltage
• Durability of more than 1000 cycles
• Removable battery 

The new color display comes in a compact size and is therefore nicely integrated on the handlebar. While the display features full connectivity with Shimano Di2 components it also allows for individual settings for the information shown. The switch has been redesigned specifically for mountain bikes. Thanks to the ergonomic design improvements, the switch is now better integrated and offers a similar feel to a gear shifter.

• Bluetooth connectivity

• The drive unit achieves a maximum power output of 70Nm and 250W

We have adopted the new Metric shock sizing standards with a Trunnion mount. Since the shock body now extends between the two lower mounting bolts, our suspension partners have more design space. This means the shock has more stroke for the same eye to eye length. Stroke on the 165mm eye to eye shock has increased from 38mm to 40/45mm.The Trunnion standard also offers structural gains. The shorter shock enables us to build a very compact frame and shock package, which integrates tightly to the seat tube. We managed to have a very tiny yet stiff linkage-lighter than ever. Thanks to the Trunnion mount construction, stand over height on the new Spark is very low. We are still able to realize a super compact full suspension frame and provide the ability to mount both a small and big water bottle.

The Spark family maintains the 165mm eye-to-eye shock length of the previous Spark 900 (our shortest shock), but realises up to 7mm more shock stroke. All Spark RC and most Spark and Spark Plus bikes utilize the FOX Nude shock, specially made for SCOTT:

-165mm Metric Trunnion shock

-40mm (100mm travel RC Spark line-up) vs. 38mm (old Spark)

-45mm (120mm travel Spark line-up)

By turning the Trunnion shock upside-down, we can fully integrate it into the frame which results in several benefits.Since the Trunnion mount is the same width as the down tube and mainpivot, we can have a very clean frame design in this critical area. The lack of tight transitions and small details allows for an efficient, continuous carbon structure. Carbon material added to reinforce the shock mount also stiffens the connection between the down tube, main pivot and bottom bracket, a key stiffness path.

The flipped shock also lowers the frame’s center of gravity helping to give a more planted feel when riding. Unsprung mass is reduced since it is the lighter part of the shock, connected to the linkage, not the heavier body which must move during an impact – the suspension system can react faster.Our TwinLoc remote cable can be routed cleanly into the down tube.

A bike deserves better than to lie on the ground when you are checking the lines of the trail or when you are taking a break. This is why we have integrated a kickstand mount on the chainstay. To provide optimal stability for all types of terrain, the kickstand is mounted as close as possible to the BB on the lowest point of the bike. The kickstand is then directly fixed into the frame to provide perfect integration.

Classic E-Bike systems use a speed sensor consisting of a magnet fixed onto a spoke of the rear wheel and the sensor itself normally located on the left chainstay. This sensor gives information to the drive unit regarding the speed which is crucial for assist management. That's why; we've developed a patented magnet mount to improve the system's integration and reliability. The magnet has been integrated into the lock ring of the Shimano rotor and the sensor is fixed in the left dropout. As a result the sensor and the magnet, compared with more traditional positioning, are now more integrated and protected from impact and dirt- both normal consequences of off road riding.
