The new suspension layout, geometry update and motor brand changes mark a major change for the new 7 series electric bicycles

This game is now over

The new Focus Jam2 7Series electric mountain bike series has undergone a comprehensive transformation, fully adopting 29-inch wheels, Shimano EP8 motor system and new cable integration settings.

In order to make riders smile, Focus believes that the best electric bikes can help more people reach their happy places, whether it is sprinting downhill, making thrill-seeking jumps or driving far behind.

According to Fox, our goal is not to produce the fastest bicycle, where hunting speed is above all else, but a bicycle that can bring fun to your riding.

Focus on the four key areas of bicycles: integration, suspension, strength and durability, and geometry. In addition, the brand ticked longer, lower, and looser boxes on its Jam2 6 series bikes.

Focus retains the aluminum structure of the new Jam2, as well as a 150 mm front and rear suspension travel. However, the 29-inch wheels of all models now cover only four sizes, from small to large.

Another major change is the integration from Bosch motors to Shimano's EP8 drive unit, subtle Shimano EM 800 switches and displays, and Focus's own 720Wh battery.

The large battery is integrated in the down tube. It can be charged on a bicycle, or it can be removed by loosening a bolt for non-bicycle charging.

Due to the shape of the down tube, Focus developed the battery, which has a slight curve to help it fine-tune the new geometry.

The power button is neatly located on the top tube, and it also has a USB-C port so you can charge the potential light of a GPS device, phone, or bicycle battery.

When it comes to integration, Focus includes its CIS (Cable Integration System), which passes gears, brakes, seatposts, and wires through the stem and head tube, and fixes them above the battery in the down tube.

The concept is to tidy up the cockpit for a stylish appearance. If you prefer to run different cockpit settings, you can. However, you need to replace the headphone cover with a compatible ACROS cover so that you can pass the cable through it because there is no cable entry in the frame.

The Focus has a custom kit between the upper tube and the lower tube, with enough space to carry some riding essentials, such as inner tubes, multi-function tools, and tire levers.

Focus has created a brand new Jam2 that is sturdy and durable, with a system weight of 150 kg, regardless of the intended use, to maintain the durability of the bicycle and the capacity of the truck.

To this end, Focus has also specified sturdy components. Of course, this means that it is not a lightweight bike, our medium bike weighs 25.3 kg, but at least it means you don’t have to worry about it becoming refined.

Focus also considered maximizing the space inside the front triangle to make room for the water bottle. The adapter fixes the bottle so as not to interfere with the rear shock absorber's carrying. You can put a 750ml bottle in a medium and larger frame.

Some additional details include double sealed bearings to help prevent dirt and dust from entering. In addition, there is a SRAM universal mechanical hanger, the protection has been fully considered, the transparent film sticker kit helps prevent scratches and heavy chainstay protectors.

One detail that may not be used often is a subtle bracket installation on the rear axle.

Fox has completely redesigned the suspension layout, but still uses its FOLD (Focus Optimized Linkage Design) single-pivot link drive platform. In addition, Focus has abandoned the vertically installed shock absorber and placed it horizontally under the upper tube.

This allows Focus to lower the standing height, lower the center of gravity, and run a longer lifter to help the bike's downhill performance.

Although FOLD is still adopted, the kinematics of the platform has been changed, and the "hump" lever curve of two-stage regression and then gradual is no longer used.

Instead, we were told that it now uses a linear progressive suspension curve. It is similar to the changes used by Santa Cruz in its new low-link impact drive design. Focus said that this gives the bike a more lively and active riding characteristics.

Focus mentioned that the anti-squat when drooping is close to 100%, so the pedaling characteristics should be very stable.

As you might expect, the new Jam2 7 series is longer and looser than the 6 series. Focus stated that the goal of its new geometry is to allow the rider to focus more on the bike to improve uphill and downhill performance.

It also uses flip chips in the shock mount to match your favorite geometry to the type of path you ride most often or on specific days. The flip chip adjusted the angle of the head tube and seat tube by 0.5 degrees, lowered the bottom bracket by 5.5 mm, changed the chainstay length by 1.5 mm, and finally changed the reach by 5 mm.

In other words, for this almighty smile maker, the geometric shapes are modern and not too wild. For example, the low setting runs at a 65-degree head tube angle, and a 76-degree effective seat tube angle, and reaches numbers ranging from a small size of 420 mm to an oversized size of 510 mm.

The 7 series includes three models: flagship Jam2 7.0, mid-range Jam2 7.9 and minimum specification Jam2 7.8. All products use the same aluminum frame and 150 mm stroke, equipped with Shimano EP8 motor, power of 250W, torque of 85Nm, and Focus's integrated 720Wh battery.
