Origin
The Focus JAM² arrived in October 2016 as one of the first credible full-suspension e-MTBs to come out of a major European brand. Built on the regular JAM trail-bike platform in Cloppenburg, Germany, the first generation used Shimano STEPS and Focus's own Tailored Energy Concept (T.E.C.) — a removable 378 Wh stick battery that could be doubled to 756 Wh with a piggyback pack. The trick was making the e-bike feel like the analogue JAM rather than a different animal, and reviewers at the time noted Focus had pulled it off. Since then the JAM² has been redesigned twice. The current 2025/2026 generation runs the 5th-generation Bosch Performance Line CX motor (85 Nm, 600 W peak), with Bosch PowerTube batteries in 600 or 800 Wh and the option of a 250 Wh range extender to reach 1,050 Wh. Travel is 150 mm rear / 150–160 mm front on 29-inch wheels, all in an alloy frame — Focus deliberately skipped carbon to keep the price aggressive. The range tops out with the Jam² 6.0 at €7,999.

The verdict
+Strengths
- 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
−Weaknesses
- 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

Buyer’s notes
№ 01
Identify which Jam² you're looking at FIRST. Standard 6.x = aluminium + Bosch + ~24kg + €4,999-€7,999. SL = carbon + Fazua + ~19kg + €5,999-€8,499. Same model name, very different bikes — wrong choice = expensive regret.
№ 02
On Gen 3 (2025+) standard: check the motor model code. BDU384Y = Bosch CX Gen 5 (eligible for free 100Nm app update). Older code = Gen 4 (NOT eligible). Bosch eBike Flow App displays the motor model — make seller open it before paying.
№ 03
Jam² 6.0 (€7,999) is the value pick on the standard line — same alloy frame as 6.7, but you get RockShox Lyrik Ultimate + Super Deluxe Select+, SRAM GX AXS Transmission, SRAM Code Silver brakes, DT Swiss HX1700, OneUp dropper, and the One Piece SL Cockpit. If you can stretch from 6.9 to 6.0, the spec jump is bigger than the €700 price gap suggests.
№ 04
If you live in an apartment without a garage charging point — Jam² standard's removable Bosch battery is materially better than Trek Rail's semi-integrated or Specialized Levo's bolt-down. Battery weighs 3-3.5kg and unclips with the included key in seconds.
№ 05
For long Baltic touring (Otepää loops, Sigulda multi-day) — pay the upgrade for 800Wh on Jam² 6.8 or 6.9. The 600Wh standard is ~40km mixed-terrain real-world; 800Wh extends that to ~55km. Add the 250Wh range extender (1,050Wh total) and you can do 70-90km on a full charge.
№ 06
Jam² SL 9.9 is the cheapest light-eMTB at €8,499 — but it's also the heaviest in its peer group (~19.4kg). If weight is the priority over price, Pivot Shuttle SL or Santa Cruz Heckler SL save 1-2kg. If price-per-spec matters more, SL 9.9 is the value pick.
№ 07
Used Gen 2 (2022-2023) Jam² in good condition: realistic price range €3,500-€5,500 in Baltic market. Check the motor model on Bosch eBike Flow App (Gen 4 BDU374Y = NOT eligible for 100Nm app update — only Gen 5 BDU384Y is). Battery cycle count is in the app too — under 200 cycles is excellent for a 3-year-old bike.
№ 08
Used Jam² SL: check the battery compartment hinge and fasteners — frequent battery removal without an on-frame charge port can wear locking mechanisms over years of use. Ask seller for a full battery health check via Fazua App.
№ 09
Jam² SL 9.9 has the 6mm Allen key for battery removal hidden inside the rear thru-axle. Verify it's still there on a used SL — replacements are not commonly stocked by dealers and you'll be stuck if it's lost.
№ 10
Don't try to convert Jam² standard to 27.5" rear (mullet). Focus does not officially support this — chainstay length and BB drop are tuned for 29" rear only, and you'll affect F.O.L.D. anti-squat behaviour negatively. If you want mullet, look at Canyon Strive:ON / Specialized Kenevo SL instead.
№ 11
Focus dealer presence in Baltics is moderate (Tallinn, Riga, Vilnius have one or two each). Confirm dealer can service Bosch motor under warranty before buying — Bosch service is widely available, but Focus-specific frame warranty work may require shipping. Pon Holdings ownership means parts availability is generally good.
№ 12
Bosch eBike Flow App 100Nm / 750W update is FREE and reversible — try it for a week, revert to stock 85Nm if you don't like the throttle aggression. Update requires Bluetooth pairing with the bike (display + remote awake) and roughly 10 minutes of standstill connection.
