Scene: you’re crushing your latest climb on your new full-suspension mountain bike. Maybe it’s the anticipation of killing the descent, or maybe it’s that your fancy new bike has the latest suspension kinematics. Either way, you feel great, if a bit winded. It isn’t until that last climb that you take a break, at which a rider passes you by with an unstrained smile. Are they just a better climber? Truth be told, they were on a Focus Jam2 Plus LTD electric mountain bike.
The Focus Jam2 Plus LTD is designed to augment fun, and Focus has developed TEC as the answer. TEC (Tailored Energy Concept) starts with a 380Wh battery (compared to the typical 500Wh). The battery is housed inside the down tube and paired with a Shimano STEPS drive system. This not only looks neat, but lowers weight; because the battery is smaller, the down tube is can be smaller without sacrificing stiffness. The result is a bike that weighs on average of four to six pounds less than most of the competition.
On the trails, the Jam2 e-mtb continues to set itself apart from the competition thanks to Focus’s patented FOLD suspension system. FOLD (FOCUS Optimized Linkage Design) is a multi-linkage suspension design that incorporates a regressive and progressive suspension kinematic. Translation? It’s supple over small bumps and into your sag point, and progressively stiffer the deeper into the suspension travel you go. The one-piece rear suspension design is lightweight and stiff; ideal for climbing, and combined with the wide 2.8” plus tires, gives it a ton of grip climbing.
You’d be hard pressed to find a bike that climbs like the Focus Jam2 Plus LTD, especially with 140mm suspension travel front and rear. What impresses is how well it works on descents. With all of that extra weight from the battery and motor (compared to a standard trail mountain bike), the bike feels really stable. The FOLD suspension gives high amounts of traction while still sucking up hits better than you’d expect for 140mm of travel. Geometry, with a 66.5 degree headtube angle and standard 74.5 degree seattube, on the conservative side of the trail spectrum, but that means the bike feels highly nimble.
Functionally, the Focus Jam2 uses a Shimano Di2-style motor-assist selector and small bar-mounted display, which is clean and clear so you can monitor speed, assist levels with ease. For bigger rides, Focus has developed an additional battery that slots atop the downtube. This boosts total battery life twice as much to 756Wh, at just an additional five pounds.
The Focus Jam2 Plus LTD electric mountain bike features a Focus Jam2 alloy frame with Shimano STEPS motor-assist and battery housed in the downtube. It uses a 140mm travel Rock Shox Recon RL fork, 140mm Rock Shox Deluxe R rear shock, and a Shimano Deore 1×10 drivetrain. A BBB brand cockpit matches to a YSP dropper seatpost, and a Race Face AR40/Novatec hub wheelset pairs to Maxxis Rekon + tires.
