Immerse yourself in the captivating tale of the Yeti 160-E.
Meet the Yeti 160-E
As the curtains rise, the stage is set to introduce the magnificent Yeti 160-E, the embodiment of precision and unrivaled craftsmanship. Yeti’s devotion to excellence is profoundly exemplified through its bifurcation of bikes into two distinct categories: the awe-inspiring “rip” and the pulse-pounding “race.”
According to Garrett Davis, the visionary Director of Marketing at Yeti, “Our race bikes are meticulously engineered to reign supreme within the confines of competition. On the other hand, our rip line beckons you to unleash your inner explorer, inviting you to embark on thrilling escapades off the beaten path, transcending boundaries that confine convention.”
In the realm of e-bikes, Yeti’s audacious move to place the 160-E within the revered “race” category reverberates like thunder, captivating the attention of the crowd. How can a 160mm e-bike compete in the arena of speed?
Prepare to be astonished, for the answer lies within the paradigm-shifting emergence of the EWS-E category in the Enduro World Series. As the first race unveiled its electrifying tale just last week, it became abundantly clear that the 160-E stands as a symbol of both revolution and dominance, defying expectations and obliterating conventional notions.

Introduction:
Except for the equipment, the EWS-E competition maintains a similar structure as an EWS race. Participants eagerly tackle numerous downhill time trial stages, aiming to secure the fastest overall time and claim victory. Nonetheless, one notable distinction exists within the EWS-E: the inclusion of a captivating “Power Stage.” This stage entails a timed technical climbing section which introduces an additional thrilling dimension to the event. It is important to note that riders are obliged to utilize consistent equipment throughout the competition in both formats. However, EWS-E riders have the unique advantage of recharging their equipment between stages.
Exploring the Format:
For a comprehensive understanding of the EWS-E, it is crucial to delve into its distinctive structure and rules. Although parallel to the conventional EWS race, the EWS-E embarks on an exhilarating journey with the integration of the “Power Stage.” This stage adds an extraordinary level of intensity by introducing a timed technical climbing segment, thereby challenging the riders’ strategic acumen.
Equipment Consistency:
Continuity in equipment usage emerges as an essential requirement in both the EWS and EWS-E competitions. Participants are bound to employ the same equipment throughout the entirety of the event. This distinctive rule contributes to a level playing field and ensures equal opportunities for all riders. Moreover, it exemplifies the significance of skill and strategy in determining the ultimate champion.
Recharging Advantage:
One noteworthy advantage granted specifically to EWS-E riders is their ability to recharge their equipment amidst the stages. This unique provision affords participants the opportunity to optimize their performance and endurance by replenishing their resources. Consequently, EWS-E riders can diligently strategize their recharging intervals to gain an edge over their counterparts and maximize their chances of victory.
Why Yeti’s First E-Bike is a Race Bike
I questioned Davis about the decision to make Yeti’s first e-bike a race-oriented model rather than a rip bike. He explained that racing has always been the foundation of their bike development at Yeti. The belief is that if a bike can perform exceptionally well under the fastest racers, conquering the most demanding tracks worldwide, it will undoubtedly deliver an incredible ride for any rider.
The Significance of EWS-E in Bike Design
The Experience of Yeti’s Design Team
But, a question lingered in my mind – how did Yeti’s design team manage to construct an e-enduro race bike if EWS-E is a relatively new format? Davis clarified, stating that while the EWS-E may be new, its courses often have similarities to the standard EWS races. They utilized their knowledge gained from their winning EWS team riders to design and engineer a bike that not only met the demands of EWS-E racing but also accounted for the added power and weight of an e-MTB.
Unique Challenges of EWS-E Racing
Addressing the Timed Uphill Stage
However, one notable distinction between EWS races and EWS-E is the inclusion of a timed uphill stage. This difference may have led to various design and tuning choices. Peter Zawistowski, Yeti’s director of engineering, shared insights regarding this challenge. He emphasized the importance of balancing suspension characteristics to perform optimally across a wide range of conditions. With an e-MTB, this balance becomes even more vital. Factors such as dynamic anti-squat and anti-rise responses, leverage rate, geometry, and chassis were all carefully considered to optimize performance for both climbing and descending. Zawistowski particularly highlighted the significance of e-MTB suspension design during technical ascents, where reduced anti-squat magnitude enhances traction, especially in situations like the timed Power stage. Additionally, the lower Switch link’s switching movement enables distinct behavior when climbing compared to descending.
Introducing SixFinity Suspension
The Innovative SixFinity System
With the 160-E, Yeti unveils its new six-bar suspension system called SixFinity. One key factor driving the adoption of this system is the motor’s placement, which occupies the space previously taken by the signature Switch Infinity translating link on their non-electric bikes. Although the six-bar system differs from the Switch Infinity (Si) system, it still encompasses some of the same features and characteristics. Notably, the 6i system possesses an inflection point near the end of its travel, where the lower link reverses direction to counteract chainstay growth and mitigate resulting pedal kickback.
Exclusively for E-MTBs
The Future of SixFinity
Yeti representatives stress that SixFinity is currently exclusive to e-MTB platforms. They confidently state that the next generation of pedal bikes from Yeti will continue to utilize their Switch Infinity platform.
Enhancing Performance with SixFinity
The 160-E Anti-Squat Plot
Reasons for Overbuilding Sixfinity for Powered Bicycles
When it comes to unpowered mountain bikes, the Sixfinity may seem overbuilt. Its seven pivots and 16 bearings make it heavy, but also incredibly rigid. This sturdiness is necessary to withstand the added weight and power of a motorized bicycle. Additionally, the engineers have made it highly adjustable, incorporating a “gear agnostic” anti-squat feature. Unlike a typical mountain bike suspension system, the cassette on the 160-E only experiences an 8.6% change in anti-squat. This intentional biasing of the anti-squat (approximately 100 percent) and anti-rise (about 65 percent) aims to prioritize traction over pedaling efficiency and maintain the bike’s geometry, aspects that Yeti considers vital for unpowered bikes but less crucial for e-bikes.
Plot of the Three Leverage Rate Positions
A lower shock mount chip offers riders the choice between three progressively increasing leverage rates: 35 percent, 30 percent, or 25 percent. Yeti explains these different rates as follows: “The stock position is set at 30 percent, providing a well-balanced ride. If you desire a more supported and efficient feel, simply switch to the 25 percent position. On the other hand, if you prefer a plusher experience with greater pop, switch to the 35 percent position (which is also ideal for a coil shock).” As a curious rider, I tested all the settings, and I found the 35 percent position to be my personal favorite.
In addition to the leverage rate options, the 160-E is equipped with a shock rate flip chip that allows riders to choose between 25, 30, or 35 percent progression. This feature becomes particularly noticeable in the 35 percent position.
Analysis of Yeti’s Leverage Curves
Based on Yeti’s leverage curves, it appears that the variations in leverage mainly occur at the beginning of the suspension travel. However, Zawistowski clarifies that while visually the delta in leverage rate magnitude is most significant at the start of the stroke, there is actually a consistent and tangible difference across the entire range of travel, with a 5 percent variation per position.
Moreover, apart from the flip-chip, the Fox Float X2 shock included in all models allows for further customization with its adjustable air spring volume.
160-E Geometry
As delivered from the factory, the 160-E comes equipped with 29-inch wheels both in the front and rear. Yeti explains that this choice is primarily driven by the desire for maximum speed in racing. However, they do mention, “We are not anti-mullet: If you want to run it, go for it.” It is worth noting that opting for a 27.5-inch rear wheel will result in a slacker geometry and even lower bottom bracket height.
Speaking of bottom brackets, the 160-E already features a low one with an estimated height of 355mm and a drop of 22.5mm, further enhancing its performance.
The Challenges of Riding an E-bike
Couple that with the manner in which you ride an e-bike—pedaling vigorously whenever possible—and you are bound to encounter its pedals. The e-bike comes equipped with 160mm cranks as standard (which is ideal because it necessitates sufficient clearance). However, due to a shortage of parts, my bike was fitted with 165mm cranks for the majority of the testing phase, and I consistently collided with stumps, rocks, and the edges of the trails. This occurred with alarming frequency. I experienced it so frequently, in fact, that I made the decision to switch from flat pedals to Shimano Trail clipless pedals after a few rides. The shift was motivated by the fact that clipless pedals are narrower and afford greater clearance.
A Geometry Table – The Details
Yah-Hoo!
When it comes to the rest of the geometry, the chart provides a comprehensive overview. However, I’ll highlight a few key points:
• Despite the fact that Yeti built the 160-E around a 29-inch rear wheel, the stays are relatively short (in comparison to an e-bike) at 446mm. This measurement is only 4mm longer than Specialized’s Turbo Levo, which was designed around a 27.5 rear wheel and has 10mm less rear travel.
• The head tube angle measures at 64.5 degrees, which is considered average for an e-enduro bike. The frame does not include any built-in geometry adjustment. Zawistowski explained, “While a flip-chip for geometry adjustment at a linkage pivot can have some benefits, it often leads to negative effects on other ride characteristics, such as anti-squat and anti-rise. The flip-chip on the 160-E was designed solely to allow adjustment of the leverage rate progression while maintaining all other attributes.”
• Due to the use of drop-in bearings instead of cups, angle sets are not available as an option. If you want to adjust the angle, your only choices are to install a longer fork and/or use a 27.5 rear wheel.
• Although the reach figures appear favorable on paper, I personally found the top tube a bit short and wished for more space in the seated position.
Yeti 160-E Builds and Options
The 160-E comes in two builds: the T1 priced at $12,700, and the C1 priced at $10,100. Customers in the USA have the option to upgrade either model to carbon wheels for an additional $900.
Both bikes utilize the same carbon frame, Shimano EP8 motor, and 630Wh battery. The primary distinction lies in the components. The C1 features lower-grade suspension components (Performance instead of Factory), a downgraded Shimano drivetrain, SRAM Code brakes, DT Swiss wheels, and a OneUp dropper post instead of the T1’s RockShox Reverb AXS.
Furthermore, both builds come equipped with Yeti’s new domestically produced thermoplastic riser bar, featuring internal routing for Shimano’s motor remote. Yeti claims that the material and manufacturing process enable the bar to effectively dissipate energy that would otherwise impact the rider. Upon weighing the bar myself, it registered at 251 grams.
Clean routing
Also, there is not the presence of a small duck-bill guard, which serves the purpose of protecting the pivots from debris.

Impressions of Riding the Yeti 160-E
A Race Bike Like No Other
The Yeti 160-E is marketed as a race bike, but I won’t evaluate it solely from that perspective. As I haven’t participated in an e-enduro race yet, I lack firsthand experience with the specific demands of such an event.
However, I could sense the racing pedigree in this bike, as the 160-E is one of those machines that, despite the cliché, truly shines when you push its limits. That’s not to say it performs poorly on relaxed trails. On the contrary, it’s akin to using a formidable double-handed weapon to slice through a delicate grape.
The performance of the 160-E lacks subtlety or restraint. It demands to be pointed, thrashed, and handled with intensity. There’s no doubt that Yeti designed this bike to excel on technical downhill terrain. The rear suspension of this bike deserves special mention, as it surpasses any other mountain bike suspension I’ve experienced. It’s difficult to put into words, but I’ll try my best.
The smoothness of the suspension, from the initial stroke to the very end, is simply outstanding. Each bump is absorbed flawlessly, with big hits having minimal impact on the bike’s stability. It effortlessly handles braking bumps, effortlessly tackles sharp obstacles, and glides over small bumps without compromising traction. It feels as if the frame and wheels have an extraordinary connection, resulting in minimal disturbance to the overall chassis due to wheel movement. I never knew mountain bike suspension could function at such a high level, offering an ideal balance of traction, support, and control. It moves precisely as needed, neither plush nor stiff, and always feels just right for the given circumstances.
In terms of rear suspension performance, the 160-E is as close to perfection as any bike on the market today.

The Unyielding Beast
Formidable, Yet Not Excessively Rigid
And let me tell you, this bike is rock-solid, sturdy, and unyielding—use your preferred adjective. However, it doesn’t sacrifice agility. It remains composed and smooth, effortlessly navigating rough corners and challenging terrain. The 38 forks might feel a tad too stiff on a lighter mountain bike, but on the front of a 50-pound e-bike like this one, they provide the perfect balance of suppleness and precision.
To truly maximize the potential of this bike, I found two modifications to be essential: installing Cush Core Pro inserts in the tires and incorporating the DSD RUNT into the fork. While the Cush Core aids in flat protection, its primary advantage lies in the additional sidewall support it offers. This is crucial considering the exceptional traction and speed that the bike delivers. The same principle applies to the RUNT, which provides significant mid-stroke support to the fork, greatly benefiting from the weight, speed, and traction involved. Furthermore, the RUNT ensures that the fork maintains a higher position in its travel, helping to mitigate the slightly quick-responding front end of the 160-E.
Braking Performance of SRAM’s Code Brakes
The SRAM Code four-piston brakes, equipped with a 220mm front rotor and a 200mm rotor in the rear, may seem sufficient for the 160-E. However, upon closer inspection, they only provide just enough power, leaving me longing for more. I also observed a slight decrease in performance and noticed some discoloration on the rotors.
Impressive Downhill Capabilities
The 160-E displays remarkable speed and fearlessness on downhill trails, but there were moments when I desired a longer and slacker ride. Nevertheless, altering these aspects may potentially diminish its impressive mid-speed handling and, surprisingly, its climbing proficiency. My concerns about the Yeti team’s decision to incorporate lower levels of anti-squat were unfounded, as the bike delivers ample rear-end support and outstanding traction during steep climbs.
Awe-Inspiring Cornering Abilities
Cornering on the 160-E is akin to a spiritual encounter. This bike offers exceptional traction, thanks to its superb suspension and weight distribution. Whether tackling a berm or maneuvering through off-camber sections with wet roots, the 160-E excels in all cornering situations.
However, it is worth noting that at high speeds, I found the 160-E slightly sensitive when initiating turns, leaving me wishing for a longer and slacker ride. Adjusting the front end with an angleset would be a great solution, but unfortunately, this option is not available due to the direct fit bearings. It’s unfortunate that this limitation prevents riders from fully customizing the geometry of the 160-E, as setup and tuning are crucial in the realm of racing.
Shimano EP8 Motor with Minor Drawbacks
Aside from Yeti’s contributions, the Shimano EP8 motor continues to impress with its smooth and responsive performance. However, in comparison to Specialized’s motor, I still believe the latter offers a superior overall experience with even greater refinement, resulting in a smoother and quieter operation. The EP8 motor does exhibit a slight backlash, which manifests as a discernible “clunk” when the motor engages and disengages, giving it a slightly unpolished feel.
Furthermore, it would be advantageous if Shimano offered a battery larger than 630Wh. It can be a disappointment when I desire to continue riding, but the battery signals that it’s time to stop.
However, it’s pretty easy to drop and swap the battery on the 160-E, making it convenient to replace the battery. So, if you decide to invest around $900 or more for an extra battery, you’ll be able to extend your riding experience. Regarding the range, it may vary depending on the conditions, but I personally tested it on a 20-mile e-bike route with a challenging elevation gain of 3800 feet. This loop consisted only of singletrack trails.
Performance and Battery Life
When I rode the 160-E, I exclusively used the “Trail” mode throughout the entire journey. Completing the ride within one hour and fifty minutes, I was left with approximately 31% of the battery capacity remaining. This demonstrates the impressive performance and efficiency of the bike.
Riding Experience
The ride itself was thoroughly enjoyable, as the bike effortlessly conquered the challenging terrains. In addition, I never encountered any issues with the battery or its functionality. With the option to change the battery easily, I was able to prolong my adventure and maximize the fun.
Therefore, the 160-E is a reliable e-bike that offers both convenience and exhilarating riding experience.
160mm cranks come as standard on the bike to improve ground clearance.
Matt PhillipsI have one crucial tip for you to make the most of this bike: get yourself into good physical shape. Above all, it was my lack of upper body strength that hindered me from fully tapping into the potential of the 160-E. It’s not that the 160-E is difficult to control; rather, the forces and weights involved demand a higher level of strength compared to an average mountain bike. And to those who claim that riding an e-bike isn’t a form of exercise: first, I strongly disagree, and second, I challenge you to take a 50-pound 160-E and ride it as fast as you can down the steepest and rockiest trail you can find. If you’re not out of breath by the end, I’ll treat you to a beer and a cookie (or just a cookie if you’re underage).
A Double Down rear tire is included by default, and this bike absolutely needs it. Nonetheless, I highly recommend adding Cush Core liners.

Final Impressions on the Yeti 160-E
I’ve often told my friends that riding an e-mountain bike is a unique experience: it’s not akin to riding a regular mountain bike, nor is it like riding a motorcycle. No other e-bike has reinforced this belief in my mind quite like the 160-E. It offers a level of speed and capability that I haven’t encountered on any other bicycle. Having said that, I don’t consider the 160-E to be in the same league as the Specialized Levo, which I find to be a more well-rounded and versatile e-bike, and one that provides a more enjoyable ride on smoother trails. In contrast, the 160-E is perfect for riders who favor a slightly more nimble enduro bike and constantly push themselves and their bikes to the limit on every single ride.
