THE NEW eONE-SIXTY SL

The eONE-SIXTY SL represents a new breed of e-mountain bike, combining the poise of an unassisted bike and the power of a Bosch SX drive unit to help you ride further and faster. With a lightweight full carbon frame, 160 mm of balanced travel and a build that blends hard-hitting performance with low weight, it blurs the line between conventional and assisted riding. The growing e-bike market is beginning to fragment between those who value maximum battery capacity and those who want their e-bike to handle more like an unassisted bike. 

Even a lightweight full-support e-bike has a significant weight penalty over an unassisted bike, so for 2025, we will expand our groundbreaking e-bike range to include our first ever light-support e-MTB - and our first ever Bosch-powered eONE-SIXTY.

The new eONE-SIXTY SL combines ‘human-powered’ bike handling and enduro tough but lightweight equipment with the latest compact Bosch Performance Line SX motor with 55 Nm, and a fully integrated 400 Wh battery, resulting in a total weight of around 19.5 kg. Instead of using fragile tyres and wheels to reduce the overall weight of the bike, we specify fit-for-purpose equipment that can withstand the rigours of enduro riding. We do not compromise on durability or performance to shave a few grams off the overall weight.
 

The eONE-SIXTY SL is aimed at enthusiast enduro riders who want the downhill agility and singletrack fun that a heavier, full-support bike can’t offer, but are willing to put in the pedal power to maximise the riding experience. The bike introduces a new suspension design, developed from the test and award-winning FAST kinematics first seen on the ONE-SIXTY and the new eONE-SIXTY lineup. It delivers 160 mm of rear wheel travel, paired with 160 mm up front, with 29er wheels as standard and enduro tough yet lightweight components. This new and exciting ‘no compromise’ platform perfectly complements the existing full-support eONE-SIXTY range.

The new carbon-only eONE-SIXTY SL incorporates some key features of our award-winning and massively popular ONE-SIXTY and eONE-SIXTY platforms, such as its flexstay technology and AGILOMETER sizing. The flexstay suspension technology means we’ve removed a pivot point for less maintenance and lower weight, it is adjustable to work with full 29“ wheels or a mixed 'mullet' setup without changing the geometry.

By creating a frame with an extremely short seat tube and speccing them with long travel seatposts (size has been calculated with the help of an extensive database), it largely allows riders to upsize (for more stability) or downsize (for more agility) without being hindered by insufficient standover - adapting the proven AGILOMETER system to the eONE-SIXTY SL platform. The size specific posts were chosen over the travel adjustable ones due to the lower weight, which is a key part of the eONE-SIXTY SL concept.

To offer enduro-focused handling with the perfect combination of stability, climbing prowess and manoeuvrability, the new eONE-SIXTY SL looked closely at its e-powered and human-powered namesakes and adapted key elements of their geometry while finely adjusting others to perfectly suit the needs of the performance-orientated rider. It features a 64.0° head angle for greater stability, a 78.5° seat tube angle for a hyper-efficient climbing position, 466 mm (size Mid) reach for high-speed composure and 620 mm (size Mid) stack for an aggressive riding position.

As with the eONE-SIXTY, we have an AGILOMETER inspired sizing that combines an extremely short seat tube with a long travel dropper post, allowing riders to choose the frame size that best suits their riding style without the need for a shorter travel dropper post. The specified dropper post lengths have been calculated using an extensive database. While the eONE-SIXTY SL comes standard with 29“ wheels, the FLIP CHIP integrated into the seat stays allows the rear wheel size to be changed from 29“ to 27.5“ without affecting the geometry.

The new eONE-SIXTY SL is aimed at enthusiast enduro riders who want an agile and capable bike downhill and are willing to put in a decent amount of pedalling effort while using the assistance to maximise the fun. They are happy to accept a small reduction in battery capacity and motor power to achieve handling and manoeuvrability normally only achieved on non-powered enduro bikes. It will also be of interest to riders who regularly choose to ride unassisted, perhaps due to riding with human-powered riders, where the low overall weight is a significant help. Adding the PowerMore 250 Wh range extender to the 400 Wh battery makes the bike also attractive to riders looking for top-end performance and comfort on extended trail rides rather than full enduro capability.

As weight is critical for this bike, it will only be available in a full carbon fibre frame to keep the overall weight of the bike as low as possible. The non-removable battery doesn’t require a downtube cut-out, further reducing weight by eliminating the need to add frame material to maintain critical frame stiffness. By combining the full carbon frame with the less than 2 kg weighing Performance Line SX motor and lightweight yet enduro-tough specification, we have managed to give our eONE-SIXTY SL the durability, grip and trail efficiency you expect from a MERIDA enduro-approved e-full suspension machine. 
 

The eONE-SIXTY SL features a new suspension design inspired by the eONE-SIXTY and ONE-SIXTY but with a distinct and more integrated look. While it has its own distinctive details, it blends seamlessly into the MERIDA full-suspension family. It will have 160 mm of front and rear suspension travel and be fitted with full 29“ wheels as standard. The FLIP CHIP integrated into the seat stays allows the rear wheel to be changed to 27.5“ without affecting the geometry, but gives the rider improved bum clearance on steep terrain and slightly more 'lively' handling than the larger, more 'stable' real 29er wheel configuration. The eONE-SIXTY SL has a 230x60 mm rear shock and its progressive leverage ratio makes it coil-shock compatible.

The eONE-SIXTY SL comes standard with 148x12 mm Boost and 200 mm Post Mount direct rear brakes for improved brake performance. On the front, the bike also comes equipped with a 200 mm front rotor for the perfect balance of weight and braking performance. 

To achieve a low overall weight, we specified size-specific long travel dropper posts. The length used has been carefully calculated with the help of an extensive database which has looked at hundreds of data sets to calculate the most appropriate length for each frame size. This, combined with the extremely short seat tube, still allows the majority of riders to make use of the proven AGILOMETER sizing system, where they choose their frame size based on the preferred riding characteristics and riding position, rather than just seat tube length. Only in rare cases, replacing the original post with a shorter travel post is needed. The 34.9 mm post size reduces stress on dropper post internals and the frame, further enhancing durability.

If you’re looking for human-powered handling and agility but want the support that only an assisted bike can offer, then the new eONE-SIXTY SL could be your perfect e-trail and e-enduro companion. Combining a lightweight carbon fibre frame with progressive e-enduro geometry and the latest lightweight Bosch Performance Line SX motor and integrated battery, the latest addition to the eONE-SIXTY family delivers 'poise and power'. Light, agile, fast and endless amounts of fun, our new eONE-SIXTY SL is the perfect e-enduro machine for riders with an active riding style.
