MMR Lyth: Sleek carbon e-enduro bike with Avinox M2S and up to 150 Nm

​Initial assessment of the Lyth

The MMR Lyth is no half-hearted foray into the performance e-MTB segment. With 800 Wh, up to 150 Nm and 160 millimetres of rear suspension travel, it boasts the specifications of a full-fledged, high-performance e-MTB. At the same time, MMR has strived to achieve a sleek frame design and a comparatively low weight. - Adrian Kaether, Test & Technology Editor

Connect MMR Many mountain bikers, particularly those riding fast cross-country and marathon bikes. With the new Lyth, the Spanish manufacturer is now striking a much bolder note: The 29-inch e-MTB combines a carbon frame, 160 millimetres of rear suspension travel and a large 800 Wh battery with the compact Avinox M2S drive unit. The top-of-the-range Lyth 00 Plus model even features a 170-millimetre fork and a steel shock absorber from Öhlins. MMR is expanding its range of e-MTBs, which until now has relied primarily on Bosch for the first time, an Avinox bike

Carbon frame with integrated shock absorber

Visually, the Lyth is one of the sleeker full-power e-MTBs. The motor and battery blend seamlessly into the lines of the carbon frame, whilst the shock absorber – partly positioned beneath the top tube – creates a distinctive silhouette. The result looks less bulky than many classic e-enduro bikes with a comparable battery capacity.

MMR manufactures the frame from what is known as mid-modulus carbon fibre. The bike is fitted with 29-inch wheels and is compatible with tyres up to 2.6 inches wide. The rear suspension offers 160 millimetres of travel. On the three standard models, MMR combines this with a 160-millimetre suspension fork; the top-of-the-range Lyth 00 Plus model features 170 millimetres at the front for even greater downhill performance.

Avinox M2S: 150 Nm at the touch of a button

At the heart of the Lyth is the Avinox M2S. In the standard assistance levels, up to 130 Nm is available; in the temporary boost mode, the torque increases to 150 Nm for a maximum of 60 seconds. Combined with the 800 Wh battery used in the Lyth, the stated peak power output is 1,300 watts.

The system is operated via wireless buttons on the handlebars and a two-inch OLED touchscreen integrated into the frame. You can choose from the following modes: Auto, Eco, Trail, Turbo and Boost. Using the Avinox Ride app, you can adjust settings such as the assistance characteristics, maximum torque and acceleration behaviour, amongst other things.

Modern, but not extreme, geometry

When it comes to geometry, MMR relies on the latest enduro specifications. In the flat ‘flip-chip’ position, the head angle is 64 degrees. In size M, this is complemented by a 475-millimetre reach, 445-millimetre chainstays and a 419-millimetre seat tube – which is still not short. The wheelbase in this configuration is 1,263 millimetres.

When the flip-chip is set to the high position, the head angle increases to 64.8 degrees, whilst the reach on size M rises to 484 millimetres. The bottom bracket is also positioned higher. This allows the Lyth to be tuned either for maximum smoothness and safety on steep terrain or for slightly more direct handling. The frame is available in three sizes: S, M and L.

The 445-millimetre chainstays promise enough agility to ensure the bike isn’t seen as merely a straight-line enduro. At the same time, the 64-degree head angle clearly shows where MMR positions the Lyth: on fast, technical trails rather than on leisurely touring routes.

Four trim levels up to 10,999 euros

According to the manufacturer’s latest specifications, the top-of-the-range Lyth 00 Plus model costs 10,999 euros. MMR fits an electronic SRAM XX Eagle drivetrain, SRAM Maven Ultimate brakes and DT Swiss HXC 1200 carbon wheels. The suspension features an Öhlins RXF38 m.3 with 170 millimetres of travel and a TTX22 steel-spring shock absorber. Despite this uncompromisingly downhill-oriented spec, the complete bike is expected to weigh less than 22 kilograms, according to the information provided so far. However, MMR does not specify a confirmed production weight on the product page.

Among these is the Lyth 00, priced at 9,499 euros. It features an SRAM X0 Eagle AXS drivetrain, a Fox Factory suspension system with a 36mm fork and a Float X shock, as well as DT Swiss HXC 1500 wheels.

The Lyth 10 costs 7,499 euros and is likely to be the most sensible compromise in the range. Its spec includes an electronic SRAM S1000 Eagle drivetrain, a Fox Performance suspension system, SRAM Maven brakes and DT Swiss HX 1700 wheels.

The entry-level model is the Lyth 30, priced at 6,199 euros. It combines a Shimano XT M8200 gear system with Deore M6220 brakes, a Fox Rhythm suspension fork and aluminium wheels. The carbon frame, M2S motor and 800 Wh battery are identical across all versions.
