The JAM² SL merges the best of two worlds: Whether you go up or down a trail, you will have maximum fun due to the best mix of e-support and the riding characteristics of a pure bike without motor. The light, full carbon frame rolling on 29" wheels is powered by the super-compact Fazua Ride 60 e-drive with a 430 Wh battery. The 160/150 mm full suspension bike is fully optimised on low weight and built around a fun-oriented geometry. You can easily adjust the bike's geometry according to your riding preferences as the JAM² SL features two points to change your settings: head angle and chainstay length. This light e-MTB makes the most of every trail.

THE RIDERS'S HIGH

MOUNTAINBIKE 08/2024

The FOCUS JAM² SL comes close to being the perfect light e-bike. It has plenty of travel, scores with great handling and an excellent drive system with a comparatively long range.

A FRAME DESIGN THAT TAKES YOU EVEN HIGHER

TOP TUBE

The top tube is a key element when it comes to adapting our e-MTBs to their specific use and habitat.

We evaluated every little detail to get our carbon layers as thick as needed for high stability, and as thin as possible for reduced weight. As a result, our engineers found the most radical and minimalist way to optimize the top tube’s cross-section with ideal relations of stiffness, modern design, and lightweight.

TOP TUBE

On top, a low stand-over height was essential for us to accomplish perfect bike handling. This led to a shock semi-integration as part of the top tube that gives you generous space for moving. Still, all parts to adjust your shock settings are easy to reach.

TOP TUBE

To underline the purity and lightness of this e-MTB, the JAM² SL features our design elements in their most reduced version. The clean silhouette and tidy shapes combined with our remarkable tie-shaped top tube represent the latest iteration of the FOCUS design language.

DOWN TUBE

When it comes to the down tube, our engineers developed a sleek design while keeping functionality on point.

The motor and battery of our JAM² SL are fully integrated which ensures optimal protection of the e-drive and makes this e-MTB not just ride but also look like a pure bike.

The thoughtfully engineered carbon layout creates the perfect balance of low weight and high stiffness.

DOWN TUBE

Additionally, great usability of the light e-MTB was crucial when designing the bike. To provide most flexibility while reducing weight, we evaluated all kinds of charging options. We decided for a removable battery that can easily be taken out of the bike on the bottom side of the down tube. As you can use the Allen key from the thru-axle of your JAM² SL to unlock the down tube cover, the only needed tool is always by your side. After opening the cover, you can easily remove the FAZUA ENERGY 430 battery with only one click.

ALL THE ENERGY YOU NEED FOR YOUR RIDER'S HIGH

The FAZUA Ride 60 drive unit provides the feeling of a natural ride but still has got your back on all climbs. The compact and light, yet powerful system has 60 Nm torque and a maximum power output of 450 W. If you need an extra push, the boost function helps you to tackle even the steepest sections.

The FAZUA system matches perfectly with our idea of a light e-MTB and is fully integrated into the down tube. Further, the quiet motor won't distract you from your ultimate riding experience, so you can let your mind flow on up- as well as downhill sections.

Thanks to the high efficiency of the FAZUA system and a battery with 430 Wh, your ride won't stop before reaching your very own Rider's High. If you really need even more, adding a range extender offers you further 210 Wh.

The drive system already features three different riding modes. On top, you can individualize the motor support based on your riding preferences via the FAZUA App. It allows you to set Max Power, Support Relation and Ramp-up according to your own personal needs.

INDIVIDUALIZE YOUR BIKE'S GEOMETRY

HEAD ANGLE POSITION

Our new JAM² SL features an easy adjustment of the head angle between 64,5° and 65,5° by turning the headset cups. Choosing a steeper head angle results in a more agile handling of the bike, while the slack position gives it a more downhill-oriented setting. Adjusting the handling of this light e-bike to your own preferences won't affect the seat angle or other parameters.

CHAINSTAY LENGTH

Thanks to our FLIP CHIPs at the rear triangle, you can balance your bike's geometry according to your riding style. The adjustment from 440 to 447 mm changes your whole set-up. When switching your FLIP CHIPs to a long position, the JAM² SL rides more stable and makes steep climbs easier. If you prefer manuals and a more agile geometry, change it to the short position and get your extra kick.

YOUR PERSONAL HIGH

Based on those two components, your JAM² SL can have four individual geometry settings with head angle slack or steep and chainstay long or short. These options also make sure that your bike geometry is well-balanced and adjusted to your size.

A PERFECTLY BALANCED FULL CARBON FRAME

Our Carbon technology pushes the boundaries of light e-MTB constructions. The carbon fibre-oriented design optimises the stiffness-to-weight ratio of our JAM² SL.

We have used a tailor-made mix of high strength and high tenacity fibres for our carbon layup. These fibres can handle the heavy forces at your e-MTB ride while offering a strong frame stiffness for agile steering.

The MAX carbon layup takes our JAM² SL 9.0 and 9.9 models even one level higher in terms of weight optimisation: It contains a significant amount of high modulus fibres that saves even more weight without compromising on stiffness.

Using carbon fibres for the front and rear triangle gave us the possibility to bring our clear vision of a stiff and stable, but light e-MTB to life. The perfect match of design and material underlines the purity and lightness of the JAM² SL.

LAYUP VERSIONS OF THE JAM² SL MODELS

ADAPTED KINEMATICS

As F.O.L.D. stands for FOCUS Optimised Linkage Design, the optimisation never stops. For the JAM² SL, we reduced the amount of linkage parts of our F.O.L.D. resulting in a significant weight loss. The updated kinematic design further reduces brake influences and gives you maximum control of your bike in every situation.

CLEAN AND GOOD-LOOKING COCKPIT

Thanks to the specially developed C.I.S. (Cockpit Integration Solution), the cockpit of the JAM² SL looks super clean. All cables run from the handlebar into the stem and through the headset into the frame of this light e-MTB. The C.I.S. also ensures constantly seamless shifting and braking.

SEALED BEARINGS

All frame bearings have an additional seal to increase their lifetime.

FRAME PROTECTIONS

We have developed custom frame protection for areas that are exposed to a higher risk of damage such as the down tube and chainstay. To protect your JAM² SL from paint damage, the accessory kit also contains custom frame stickers.

MAXIMUM SYSTEM WEIGHT

This sportive and light e-MTB is made for a total system weight (bike, rider and equipment) of 135 kg.

BIKE CLASSIFICATION

Type of bicycle (examples): All-Mountain bikes

Description: Applies to bicycle and EPACs and includes Condition 1, 2, and 3, or downhill gradients on rough trails at speeds less than 40 km/h, or both. Jumps are intended to be less than 120 cm.
