JAM² SL 8.7

For MTB speed, tire choice and rolling resistance matter a lot, and that's baked into the score. If it's an e-bike, think of this as a bike speed feel score: how the parts and setup help the bike move fast. It trends this way because of 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.

If your rides include hills, it rates 1.1/10 for climbing. Within e-mountain bikes, it sits near the bottom. This setup leans heavily toward ‘push’ rather than ‘spin’ on climbs. The easiest gear works out to about 72.0 gear inches. Most comparable bikes have an easier low gear; this is easier than only about ~1% of them. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. At about 20.2 kg, it’s a heavy build; the low gear matters even more when the slope kicks up. Being an e-bike helps on climbs because the assist adds steady push when you need it. This is happiest on flatter terrain; steep stuff will feel demanding. 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.

Suspension rating is 3/10 — “Basic bump control”. This level is meant to take the edge off smaller impacts and reduce wheel deflection. Suspension at both ends helps keep wheel tracking steadier when the surface gets rough. It helps the bike stay a bit calmer over repeated small bumps. It reduces small deflections, but it won’t erase bigger hits. You’ll get better control on light roughness, but larger impacts can still unsettle the bike.

Sporty fit - you'll lean forward more and feel ready to push the pace. It feels this way because there's about 43 mm of drop to the bars (moderate), with roughly 649 mm of forward stretch to the bar (extreme). Estimated lean is about 28 degrees.

In E-bikeMountain / Crosscountry, So it lands in Moderately Adjustable. What affects adjustability on this bike: Standard cockpit parts make it simpler to fine-tune your position over time, Routing through the headset can make cockpit swaps harder than normal internal routing. Another point: A round post makes fit changes simpler than proprietary shapes. This mainly reflects how easy it is to adjust or swap key fit parts over time.

Comfort comes out to 6.8/10, which usually translates to a nicely smooth ride. That’s why it’s labeled Comfortable. It’s running about 63 mm tires on 700c wheels, and the high-volume tires add a lot of damping and grip on roots, rocks, braking bumps, and repeated hits. The posture is forward, attacking (posture 7/10), which puts you in an attack stance, which can feel more intense on long, rough descents.

This is priced well above what we’d usually expect for a similar setup. The value score is 1–10. Higher means better value for money; lower means the price is high for what you get. Uses MSRP as a baseline; real-world prices can be lower (discounts can change the value). On the spec comparison, it sits roughly 54% above what similar builds typically cost. In its peer group, it’s one of the pricier listings, beating only about 6% of them. To anchor it: price €6.615 versus an estimated €4.305 for a similar build. Overall, you can likely find better value elsewhere.

This bike is best for smoother trails where speed and efficiency matter. Suspension travel is unknown in this entry, so the surface range uses the clearest available signals. The Full setup supports this riding style.
