The Living Link™ system re-imagines and reinvents full-suspension technology to provide riders with multiple benefits over conventional systems. Read More
Leaf Spring is partially flexed, adding support in the beginning of the sag range.
"Both the Mayhem 130 and Mayhem 150 are incredible trail bikes, which I would put again at the top of my favorite-bikes-of-all-time list."
To honor our fan favorite Mayhem 150, we created this stunning new limited edition Zombie Skin colorway. Get one today and be one of the fortunate few to get your hands on this glossy ghoul.
The Mayhem 150 is built for fast and confident descenders who want to climb faster and cover more ground, because every extra summit bagged is another descent gained.
We took the legendary qualities of our Living Link and integrated them into a frame with a long, low and slack geometry and steep seat tube—a geometry that Spot pioneered and which has revolutionized mountain biking. Tuned for 150mm of travel, the ride-enhancing qualities of Living Link really shine on the M150. The result is a six-inch travel bike that's strong, light, and centers the rider for aggressive descending and effortless climbing.
At the heart of our award-winning Living Link™ suspension platform is an aerospace-grade titanium leaf spring which helps riders accelerate up climbs without locking out, while also providing a torsionally and laterally stiff linkage between the front and rear triangles for precision carving.
A Geometry Adjuster lets riders slacken the head tube angle and lower the bottom bracket for stability in high speed turns. The super low top tube provides easy standover clearance, and a short seat tube accommodates longer dropper posts. The 150 shows that the only thing better than causing some mayhem is causing even more.
The beating heart of the Mayhem’s ride performance is the titanium leaf spring technology that has won our patented Living Link™ suspension platform numerous accolades and awards. The animation above helps to visualize the special qualities of Living Link™ and its ability to store and release energy that boosts pedaling performance. At rest (or when airborne), the Living Link™ leaf spring is relaxed. As the suspension compresses, the leaf spring begins to flex, supporting the rider and widening the sag sweet spot. As the leaf spring continues to flex it stores energy that assists the system’s compression until, at full-bottom-out and maximum compression, it returns to a relaxed state. As the bike’s suspension enters its rebound phase, the leaf spring goes from relaxed to partially flexed, storing and controlling rebound energy. Midway through the rebound, the leaf spring is fully flexed, a position in which it is fully loaded up with rebound energy. As the rebound continues toward its relaxed state, it releases that stored energy to provide a slight power boost.
Living Link™ also addresses a flaw of typical suspension systems: lateral and torsional flex. The titanium leaf spring, which is manufactured locally by a Colorado aerospace components manufacturer, is extremely stiff laterally and firm torsionally. Think about a metal ruler. It is easy to bend across its flat surface but tipped on edge that ruler is virtually impossible to bend. What that means is the Mayhem carves hard, with a solid connection between the front and rear triangles.
The Mayhem’s frame shape is driven by a Force-Response design philosophy. We shaped and engineered the bike’s frame based on detailed analysis and testing both in the lab and on the trail. The result is a bike that heightens pedaling efficiency, maximizes strength and durability, and focuses material in areas where it is most needed while minimizing material (and weight) where a streamlined design improves performance and efficiency.
The forward portion of the top tube is shaped to quietly communicate and diffuse the large compressive forces this area of the bike absorbs, while the rearward portion is slimmed to handle the smaller forces delivered through the seat tube. The upper control link has been designed to deliver superb suspension response, precise shock control and excellent torsional stiffness, all while minimizing stress on the seat tube structure.
The twin-strut rear swingarm supports the crucial connections between the front and rear triangles and manages the intense energetic loads generated by the rear wheel, while remaining slim and compact for reduced un-sprung inertia. The main pivot yoke, connected to the titanium leaf spring, spreads the Enduro dual-row full-complement bearings as wide as possible for maximum durability and prolonged bearing life. Tires are crucial to bike handling and frame performance. We shaped the chain stays and seat stays to give the Mayhem loads of clearance for wide-diameter tires up to 29x2.5", with some 29x2.6" tires working as well.
In totality, the Mayhem frame is one of the most advanced, efficient, durable, low-maintenance, and fast mountain bike frames on the market.
The Mayhem’s geometry illustrates our firm belief that a bike should maximize a rider’s strengths and minimize their weaknesses. It should put them in the most athletic position to succeed in a variety of trail conditions, allowing riders to cover ground more easily. We designed the Mayhem to place the rider’s weight precisely between the front and rear wheels. We accomplish this by extending the measurement between the bottom bracket and front axle, by slackening the head tube angle for better handling on steep and rough terrain, and by steepening the seat tube angle. This geometry eliminates front-end lift during seated climbing but provides ample room to move and shift your weight when descending. All of this means you spend less energy balancing your bike, allowing you to feel fresh and juiced up for bursts of power when climbing. The Mayhem’s geometry improves the rider’s performance at all speeds, up and down, slow or fast, on all terrain, so that you can explore more, ride more, extend your range and cover more ground. Because every extra summit bagged means another thrilling descent.
Kinematics are the properties of an object in motion. We engineered the Mayhem to have an energetic pedaling response, but with reduced chain growth deep in the stroke for uninterrupted power delivery in rough terrain. In nerd speak we describe this as a seamless progressive leverage ratio: Soft off the top, ample mid stroke support from the leaf spring, and ramp at the end to prevent hard bottoming and soak up big hits. The Mayhem’s kinematics eliminate the need for shock lockout due to the power boost provided by our Living Link™ suspension. All of this means that climbing takes less energy and more watts are sent to the wheel with every pedal stroke.
Full shralp mode is only a few moments away with our Geometry Adjuster which lets the rider swap between HI and LO modes in less than 30 seconds with one tool. Slacker, lower, shreddier. Adjust it on the trail or set it and forget it. Our goal is to provide riders with options that allow them to tailor and fine-tune their Mayhem to their riding style. It’s like getting two bikes for the price of one.
We design and test our frames to the highest standards so you can be confident in your investment. Should you have an issue with your Spot frame, we will warranty it against manufacturing defects for the lifetime of the frame. Of course there's some fine print (read here), but if you buy a bike and ride it as it is intended to be ridden, we've got your back. And if you do get into a fender-bender, we have a fantastic crash replacement program as well.
Climbs like a 130mm bike but soaks everything up like the 150/160mm that it is.
