Downhill-oriented, powerful, and fast: the DECOY is an aggressive enduro bike with gravity DNA. On the descents, it eats roots and rocks like a kid digging into a bag of candy. Thanks to the powerful motor it gives you the same feeling on the way back up – more fun without the need for a shuttle. Simply put, the DECOY delivers everything you expect from a YT. And a water bottle mount.
To prepare it for heavy missions in demanding terrain, we’ve equipped the DECOY with a mix of wheel sizes; 29 inches in the front and 27.5 inches in the rear. This concept, which has been used in motocross for a long time already, combines the advantages of both wheel sizes in one bike.
Up front, the 29-inch wheel rolls over obstacles with ease and provides extra insurance against going over the bars. It runs with higher tire pressure and cuts through rough terrain with precision. The voluminous, 27.5-inch rear tire can be run with less pressure for increased traction and comfort.
The DECOY combines the unlimited on-trail performance of a YT with the advantages of electrical assistance. With E-MTB optimized kinematics, a balanced geometry and an integrated Shimano motor this newly developed frame serves up an agile ride. Out back, we rely on our award-winning, low leverage ratio Virtual 4 Link suspension technology that is supple off the top, supportive at mid-stroke and plenty progressive at end-stroke.
Additionally, we have minimized the pedal kick-back to avoid any negative influences on the suspension action. The highly functional frame design also scores extra points in the looks department thanks to the fully integrated battery and motor. Features like internal cable routing, double-sealed bearings and integrated frame protectors underline our high quality standards and help increase the service life of the DECOY.
The Decoy is an all-around work of art. It makes all the boring trails fun and fast! I was very surprised at how fun and easy to ride, jump, and spin, while still getting a work out in!
Motor: Shimano STEPS E8000
When it comes to the motor, we have chosen the Shimano STEPS E8000 for its natural ride feel and its 250 W of power that allow the DECOY to master the steepest of climbs. At 2.8 kg, this quiet motor is one of the lightest on the market and thanks to its slim profile it is also easy to integrate in the frame. The lightweight and slim Shimano STEPS E7000 display lets you choose between three support modes to achieve a range of approximately 100 km (Eco). The settings can also be adjusted wirelessly via the Shimano E-Tube smartphone or tablet app.
YT custom battery
The 540 Wh battery is our own development. For dependable performance and long lasting power, we use thirty battery cells of the very latest technology – in fact the very same type of cells that Tesla features in their cars. The battery is fully integrated in the downtube and is held in place by two dedicated bolts. The battery can be charged both on and off the bike, and the cover is easy to replace in case of damage.
Integrated Power Switch
The On/Off switch is tucked away underneath the toptube, which protects it against damage and dirt while also giving the frame a clean look.
V4L / Virtual Four Link
Our proven suspension technology has been developed together with the YT MOB on the race track and further refined for the unique ride feel of our E-MTBs. The outstanding small bump compliance virtually sucks you to the ground while the great midstroke support really optimizes the use of the available travel. The generous amount of sweet pop makes sure you can get airborne at a moment’s notice. So you don’t bottom out harshly even after hitting the biggest jumps, the ending stroke spring curve is very progressive. V4L supports you around the sag point, ready to absorb obstacles but without being affected by pedaling forces.
The FlipChip lets you quickly and easily adjust the DECOY to your riding style. The low position gives you a more aggressive headtube angle, more BB drop and more stability – perfect for fast and rough downhill sections. The high position provides a steeper headtube angle, so you can beat those grueling uphills and snap around tight turns with ease.
Race-Specific Advanced Sealing Concept, Axial Lip-Seal (RASCAL)
In addition to the industry-standard internal seals of our high-quality, double-sealed full complement bearings, we use self-developed sealing washers that protect all suspension linkage bearings and keep water and dirt at bay. Their axial lip seals considerably increase the service life of the bearings to make sure that every DECOY can withstand the abuse that aggressive mountain biking brings with it.
Perfectly integrated guards protect the frame against rock strikes and scratches. The downtube is protected by a skid plate while the chain stay and seat stay guards help reduce the noise from the drive train. To further improve on this aspect, we have equipped our new “Hulk” chainstay protector with braking bumps.
Fork Impact Protection
The Fork Impact Protection prevents damage to the frame in case of a crash or a failure of the Acros BlockLock headset.
Chainsuck Mech Hanger
The Shimano Direct Mount-compatible chainsuck derailleur hanger protects the frame from chain damage to help increase its service life. The Di2 cable is internally routed to protect it from damage as well.
Internal Cable Routing
Details like internal cable routing with built-in cable guides underline our claim to fame in the world of high-quality carbon bikes. For ultimate protection, the cable is almost entirely hidden in the frame, while the perfectly integrated ports and cable clamps make for a super-clean look. The full-length cable guide is held in place by a bolted clamp in just one area, making it easy and fast to swap cables when needed. Newly developed Cable Plugs hold the cables in the frame while sealing the ports to prevent any damage. In the downtube, cable guides and cable clamps above the battery protect the cables against damage and help prevent noise while a cable duct leads the cables safely past the motor to the frame ports.
Single Sided Hardware Access
MOB-pit approved: All the linkage hardware can be fully disassembled and assembled from one side of the bike. This makes maintenance easy and fast, since you no longer have to turn the frame around to work on it.
