JAM² Unterschiede Grafik

The JAM² covers the widest range of our SQUARED EXPERIENCE thanks to two different e-drive systems. You choose which JAM² fits you and your purposes. The Shimano EP8 e-drive offers flexibility with 756 Wh battery capacity split into two batteries. You decide if you are going super light and agil, close to a pure MTB feeling, or adding a second battery for super long rides. Always as much energy as you need – you can easily choose ahead of every ride. The JAM² Bosch Performance CX e-drive 2020 is positioned in between those two. 625 Wh battery capacity is sufficient for your long rides not worrying about reach.

JAM²: Die Entscheidung JAM²: Die Entscheidung
Phil’s mountain tour
JAM²: Die Entscheidung JAM²: Die Entscheidung
FOCUS JAM² mit Shimano E8000 und T.E.C. pack

Phil weighs 83 kg and is forever looking to make elevation gains. He loves conquering the mountains. For long mountain tours, he uses the T.E.C. Pack. While he certainly makes use of every trail opportunity that presents itself, he paces himself and makes economical use of the assistance too. And that’s why he mainly rides in Eco mode.

Saturday's appointment
JAM²: Die Entscheidung JAM²: Die Entscheidung
FOCUS JAM² mit Bosch Performance CX 2020

Every Saturday, Marie and her friends are meeting for a mountain bike ride. All members of her group are experienced riders and their ride includes a lot of challenging trails where they push themselves to new limits. Marie uses the "eMTB" mode that adapts optimally to her riding style. Marie lives on the 5th floor and she does not have a power outlet in her basement. Therefore she takes the battery up to her flat to charge it.

Chris’ trail tour

FOCUS JAM² mit Shimano E8000

Chris weighs 75 kg and is a mountain biker through and through. He’s all about riding as many trails as possible – both uphill and downhill. He uses the assistance in a rather specific way. He rides in Eco, Trail or Boost mode depending on the situation, and occasionally also rides without any assistance too.


The JAM² in action

JAM²: Einsatzgebiet

The JAM² Bosch and JAM² Shimano have different geometries and therefore please different riders. The JAM² with Bosch e-drive is made for rough trails and as a result appeals especially to experienced riders. By contrast, the JAM² with Shimano e-drive feels at home on a wide range of trails and spoils the rider with a super light, agile and balanced riding experience that probably feels more familiar to a lot of riders. If you are looking for a wider allround range with Bosch e-drive, you should consider the THRON².

Different geometry
Das E-MTB FOCUS JAM² und seine Geometrieunterschiede

The geometry differences in detail read as follows: The chainstay of the JAM² Bosch is 30 mm shorter than the one of its Shimano equivalent. Especially riders who control their ride in rough terrain with the chainstays will love this greater manoeuvrability via the rear. Additionally, the 1°-shallower steering angle and 20 mm-longer reach ensure smoother riding over rough terrain. The JAM² with Shimano e-drive offers a well-balanced, nimble geometry that can easily be steered via the front.

150 mm F.O.L.D. suspension travel
E-MTB JAM² mit 150 mm Federweg F.O.L.D.

All JAM² models come with 150 mm front and rear suspension travel. 150 mm suspension travel that feels like more. You’ll notice the difference. Thanks to the two-phase kinematics, F.O.L.D. is extremely sensitive while still being sufficiently progressive and retaining sufficient reserves. Naturally, our F.O.L.D. chassis has been specially designed to meet the increased demands placed on eMTBs. We recommend 30% sag.

Wheel sizes to choose
Zwei Laufradgrößen zur Wahl beim FOCUS JAM²: 27+ und 29 Zoll Laufräder.

You can choose between different wheel size combinations for the JAM² based on your riding style and preference. Our wider 27+ tyres (model designation: “Plus”) offer plenty of grip and control, while the JAM² with 29" wheels (“Nine”) affords an impressively precise ride and will appeal to fast riders in particular. The JAM² with 29" wheels on the front and 27+ tyres on the rear ("Drifter") combines the best of both worlds.  But even if you pick one or the other now, you always have the option to switch to a different wheel size later thanks to the FOCUS Flip Chip (JAM² Bosch).
