Jam²
Algupära
Focus JAM² saabus 2016. aasta oktoobris kui üks esimesi usaldusväärseid täisvedrustusega e-maastikujalgrattaid suurelt Euroopa kaubamärgilt. See ehitati tavalise JAM-i trail-jalgratta platvormile Cloppenburgis, Saksamaal. Esimene põlvkond kasutas Shimano STEPS-i ja Focusi enda Tailored Energy Concept (T.E.C.) — eemaldatavat 378 Wh pulgakujulist akut, mida sai topeltpakiga kahekordistada 756 Wh-ni. Trikk seisnes selles, et e-jalgratas tundus nagu analoogne JAM, mitte nagu teistsugune loom, ja toonased arvustajad märkisid, et Focusil see õnnestus. Sellest ajast alates on JAM² kaks korda ümber kujundatud. Praegune 2025/2026 põlvkond kasutab 5. põlvkonna Bosch Performance Line CX mootorit (85 Nm, 600 W tippvõimsus), Bosch PowerTube akusid mahutavusega 600 või 800 Wh ning võimalust kasutada 250 Wh ulatuse laiendajat, et jõuda 1050 Wh-ni. Käigu pikkus on 150 mm taga / 150–160 mm ees 29-tollistel ratastel, kõik alumiiniumraamil — Focus jättis teadlikult süsiniku vahele, et hoida hinda konkurentsivõimelisena. Valiku tippmudel on Jam² 6.0 hinnaga 7 999 €.

- Abiklass
- EU EPAC pedelec — assist cuts at 25 km/h, ≤250W continuous. Treated as a bicycle in EE/LV/LT (no licence/registration). The 100Nm/750W app update raises peak only, keeps continuous within EPAC limits.
Verdikt
- Bosch CX Gen 5 motor (standard line) is finally quiet — the characteristic Gen 4 rattle on rough descents is gone — with a free firmware path to 100Nm / 750W / 400% support
- Best price-to-spec ratio in the Bosch CX Gen 5 class — Jam² 6.7 at €4,999 undercuts equivalent Trek Rail / Specialized Levo / Canyon Spectral:ON entry trims by €500-€1,500
- Class-leading touring range: removable modular 600/800Wh PowerTube plus optional 250Wh extender = up to 1,050Wh, and the battery unclips with a key for indoor charging
- F.O.L.D. linkage descends superbly — composed and absorbent, reviewers say it 'rides as if it weighs 10kg less'
- Practical, owner-focused touches: AirTag mount hidden under the battery, integrated triangle frame bag (L/XL), and a 10-year alloy frame warranty unusual for the class
- C.I.S. 2.0 internal cable routing through the headset complicates servicing — EMTB Magazine called it 'spaghetti' and a step back from the older external routing
- At ~24-25kg the standard 6.x is mid-pack heavy for full-power e-MTB, and the Bosch motor still has an audible whine even on Gen 5
- Jam² SL: no on-frame charge port — the 430Wh battery must be removed (6mm Allen key hidden in the rear thru-axle) for every charge, an extra step for garage chargers
- Jam² SL is the heaviest light-eMTB in its peer group (~19.4kg vs lighter Pivot Shuttle SL / Santa Cruz Heckler SL), and the 430Wh battery is small for long tours without the extender
- Gen 3 flip-chip removal (fixed 65° head angle) removes geometry tuning options, and the Fazua Ring Control on the SL feels cheap-plastic with weak tactile feedback
