Crestline is making waves in the e-mountain bike world with its innovative small-batch strategy, attracting a growing fanbase enamored with the intricate details and robust suspension of their latest offerings. The all-new S180 and LS160 models are here, sporting the same frame design as their predecessors yet pairing it with Bosch’s state-of-the-art CX motor and highly efficient batteries that promise a thrilling ride!

What's New?

These newly updated bikes come in two distinct forms: the aggressive long-travel S180 and the slightly more tame LS160. For those who prefer more flexibility, Crestline also introduces the frame-only RS option, a standout in the market, allowing enthusiasts to customize their e-mountain bike to their heart's content.

A major perk of Crestline’s innovations lies in Bosch's revamped motor and battery system. The new setup not only boasts a sleeker design but also sheds some weight: the previous 750Wh battery weighed in at a hefty 4.4kg, while the new 600Wh and 800Wh versions weigh just 3.0kg and 3.9kg, respectively. The motor itself has also slimmed down by approximately 100 grams, enhancing overall bike performance and user experience.

Versatile Design

One of the standout features of Crestline's frame design is the ability to swap batteries without removing the motor. This unique approach enhances the durability and user-friendliness of these bikes, a vital factor for any serious mountain biker. With the frame accommodating Bosch’s new battery specifications, buyers can easily choose between 600Wh or 800Wh options at the time of purchase and even switch-up battery sizes in the future.

Another customizable feature is the option to choose between MX (27.5") or full-size 29" wheels. Each bike comes with a dedicated swingarm to fit either wheel size, offering riders incredible adaptability on the trails.

Geometry and Stability

Crestline has made specific adjustments to accommodate the different wheel sizes, though overall geometry remains consistent. Riders can select from three sizes, with reach measurements at 450, 475, and 500mm, ensuring a personalized fit. The bikes feature a 63.5° head angle for the S180 and a slightly steeper 64° for the LS160, resulting in optimal performance across various terrains.

Adjustable seat tube angles between 77° and 77.5° provide an upright riding position, perfect for tackling steep climbs effortlessly. The integration of a straight 56mm head tube allows for additional reach adjustments with the stock headset on the LS model.

Suspension Mechanics

Riding on Crestline's success, the dual-link suspension is designed in collaboration with Cascade Components, utilizing a VPP-style layout that allows you to switch between 161mm and 182mm travel options thanks to an accessible flip chip. The rear wheel movement is expertly controlled, minimizing chain growth while allowing for smooth travel dynamics.

Thrilling Ride Experience

With my initial ride on the S180 taking place during a heavy downpour, I was eager to test how the bike performed in challenging conditions. The Bosch motor impressed me with its power delivery, making uphill maneuvers feel almost effortless. The bike maintains a high, responsive feel that eases traversing rocky trails.

On descents, the suspension provided incredible grip, absorbing shocks while keeping the rider stable - a truly exhilarating experience! Even though its nearly 50-pound weight is noticeable, the handling is surprisingly agile, facilitating easy maneuverability. This flexibility is complemented by the option to build your bike from the frame up, a rarity in the eMTB market.

Conclusion

Crestline's S180 and LS160 e-mountain bikes are not just machines; they are a statement of innovative engineering and customization. As riders increasingly seek personalized setups, these bikes offer unique solutions for a wide array of preferences and riding styles.
