JAM² 8.7

This off-road speed score leans toward efficient rolling, not downhill stability or comfort. In comparison with more aero-focused bikes, this build is shaped by a heavier build, wheel momentum that helps it carry speed between pedal strokes, typical trail-width tires, and a more budget-friendly drivetrain that focuses on value. That's why it trades speed for comfort, durability, or practicality.

Climbing rating: 1.1/10. Within e-mountain bikes, it ranks near the bottom. On steep gradients, you’ll be grinding more than spinning. Your easiest gear lands around 72.0 gear inches. Most comparable bikes have an easier low gear; this is easier than only about ~1% of them. Think of “gear inches” like a difficulty score for your easiest gear: lower = more spin-friendly on climbs. With roughly 23.7 kg under you, you’ll feel the weight on longer climbs even with a decent low gear. E-assist can take the sting out of steep ramps, especially at lower speeds. Expect more grinding on climbs than easy spinning. Specs can vary by size and build, and some manufacturer details aren’t always published, so treat this as a strong guide rather than a guarantee.

On the suspension scale, it comes in at 3/10 — “Basic bump control”. It’s designed for light bump absorption and steadier tracking on uneven patches. Full suspension helps the bike stay calmer under braking and cornering on rough sections. You’ll feel less chatter, but large impacts can still knock the bike off-line. On choppy terrain, it can help the wheels track more consistently. You’ll get better control on light roughness, but larger impacts can still unsettle the bike.

Sporty fit - more tuck for efficiency, but still manageable for many riders. That's driven by there's about 88 mm of drop to the bars (large), with roughly 672 mm of forward stretch to the bar (extreme). Estimated lean is about 34 degrees.

In E-bikeMountain, Net result: Moderately Adjustable. Main reasons for the fit flexibility result: Separate bar and stem components keep fit changes practical, Cables routed through the headset add complexity when changing the cockpit, Standard seatpost sizing improves compatibility for different setbacks and lengths; Having a dropper increases how adaptable the bike feels in different situations.

This scores 6.9/10 for comfort, so it feels easygoing over rough patches out on the road. That’s the reason it lands as Comfortable. It’s running about 66 mm tires on 700c wheels, and the big tires calm small hits and take the edge off trail chatter on roots, rocks, braking bumps, and repeated hits. The posture is forward, attacking (posture 8/10, torso ~34°), which puts you in an attack stance, which can feel more intense on long, rough descents.

The price looks hard to justify versus similar options. Value is scored 1–10: higher is better value, lower means you’re paying more than similar bikes. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). On the spec comparison, it sits roughly 39% above what similar builds typically cost. In its peer group, it’s one of the pricier listings, beating only about 13% of them. To anchor it: price €6.299 versus an estimated €4.538 for a similar build. Put simply: it’s priced more like a premium pick than a value buy.

This setup is aimed at fast trail riding on less extreme terrain. Suspension travel details aren’t available here, so the label follows the category and the rest of the setup. Suspension type (Full) fits this kind of terrain.
