JAM² 7.8

For MTB speed, tire choice and rolling resistance matter a lot, and that's baked into the score. In day-to-day use, it's more about stability and usefulness than feeling fast. What pushes it in this direction is 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.

Climbing rating: 1.1/10. Within e-mountain bikes, it ranks near the bottom. The lowest gear is very tall when the road tilts up. That lowest gear comes out around 77.3 gear inches. This sits at the tough end — easier than only about ~1% of similar bikes. We use “gear inches” as a shortcut for climbing gearing. Lower numbers mean you can spin more easily when it gets steep. With roughly 25.0 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. On proper hills, you’ll feel it — this setup isn’t built to make climbing effortless. 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 suspension support it’s 7/10, marked “High-impact ready”. It typically supports higher-speed rough sections where impacts stack up quickly. Suspension at both ends helps keep wheel tracking steadier when the surface gets rough. This level is meant to keep the bike composed when hits are bigger and frequent. On rough trails, this level aims to keep the bike settled under braking and cornering through repeated hits.

Balanced fit - a neutral road posture that suits most riders. You get this posture because there's about 44 mm of drop to the bars (moderate), with roughly 634 mm of forward stretch to the bar (very long). Estimated lean is about 28 degrees.

So it lands in Moderately Adjustable. Here is the simple reasoning behind the fit flexibility rating: Because the bar and stem are separate, changing reach or bar shape is usually straightforward, Hidden cables usually add a little friction when you swap bars or stems, Standard seatpost sizing improves compatibility for different setbacks and lengths. At the same time, The dropper post improves on-the-fly position changes. In practice, it is about how easy fit changes are with normal parts and service work.

Comfort comes out to 8.2/10, which usually translates to a plush ride. For Enduro, it’s labeled Firm. In absolute terms it’s plush; it’s just not as sofa-soft as the most plush setups. It’s running about 63 mm tires on 29" 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 loads the front wheel, which feels great for control but a bit more direct through the bars.

In simple terms, it comes out as ‘about right’ for the category. 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 estimate, the price is close to what we’d expect for a comparable build. Among comparable bikes, it sits around the middle on price (cheaper than about 60% of listings). Quick reference: €6.825 listed versus about €6.327 for a comparable build. Overall, it sits in the expected range for the category.

This bike is built for rougher, more technical trails where control matters. It has about 150 mm of suspension travel (how much it absorbs bumps), which helps on rough, technical trails. Overall, the setup matches this surface range well.
