JAM² 7.9

It trades speed for comfort, durability, or practicality. For MTB speed, tire choice and rolling resistance matter a lot, and that's baked into the score. The score is largely shaped by a heavier build, wheel momentum that helps it carry speed between pedal strokes, typical trail-width tires, and a solid drivetrain that supports efficient riding.

Uphill performance score: 1.1/10. Within e-mountain bikes, this comes out near the bottom. This setup leans heavily toward ‘push’ rather than ‘spin’ on climbs. That lowest gear comes out around 84.4 gear inches. This sits at the tough end — easier than only about ~1% of similar bikes. Gear inches is basically “how easy is the easiest gear”. Lower numbers help you keep your legs spinning on steep bits. With roughly 24.9 kg under you, you’ll feel the weight on longer climbs even with a decent low gear. Being an e-bike helps on climbs because the assist adds steady push when you need it. Expect more grinding on climbs than easy spinning. Build kits can differ by size and spec level, and not every detail is published by every brand, so use this as a practical guideline.

Suspension sits at 7/10, in “High-impact ready”. That usually means it’s built for harder hits and rougher trails with steadier wheel tracking. Suspension at both ends helps keep wheel tracking steadier when the surface gets rough. It’s designed to stay composed when impacts come quickly one after another, especially at higher speeds.

Balanced fit - a neutral road posture that suits most riders. That's driven by there's about 44 mm of drop to the bars (moderate), with roughly 634 mm of forward stretch to the bar (very long). You'll likely be near 28 degrees of lean. Front-end spacers are estimated around 14 mm.

The cockpit is modular (separate stem and handlebar), so it is easier to adjust or swap fit parts, Internal cable routing can slow down fit-related part changes, Round, standard seatposts are generally easier to adjust and swap. Plus, Having a dropper increases how adaptable the bike feels in different situations. Overall, it is Moderately Adjustable. This mainly reflects how easy it is to adjust or swap key fit parts over time.

This scores 8.3/10 for comfort, so it feels highly forgiving out on the road. For Enduro, it’s labeled Firm. In absolute terms it’s highly forgiving; it’s just not as sofa-soft as the most plush setups. It’s running about 65 mm tires on 29" 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 7/10), which loads the front wheel, which feels great for control but a bit more direct through the bars.

You may be paying a premium here. 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). Based on the spec estimate, it’s about 18% above the typical level for similar builds. Compared with similar bikes, it trends a little expensive (cheaper than about 44% of listings). Quick reference: €8.190 listed versus about €6.934 for a comparable build. Bottom line: you may be paying extra versus similar options.

This setup suits steeper, rockier terrain and harder hits. It has about 150 mm of suspension travel (how much it absorbs bumps), which helps on rough, technical trails. The Full setup supports this riding style.
