Résumé

The Focus Jam2 is a versatile and capable enduro e-mountain bike, praised for its redesigned geometry, plush suspension, and powerful Bosch Performance Line CX motor. It offers a smooth ride over rough terrain and efficient performance on singletrack trails, with options for lighter or longer-range batteries. While it excels as an all-rounder, some reviews note its weight and complex cable routing as minor drawbacks.

Pros
  • Completely redesigned for versatility

  • Plush & active suspension performance

  • Powerful Bosch Performance Line CX motor

  • Options for lighter 600Wh or bigger range 800Wh battery

  • Well-balanced weight distribution

Cons
  • Not a lightweight bike

  • Cable routing through stem and headset is messy & complicated

  • Limited ability to fit a longer travel dropper post

Focus Jam 8.9 first ride review - MBR

févr. 2022 · Alan Muldoon

Focus launched its redesigned trail bike last year with an alloy frame and an impressive price tag for a brand sold through a dealer network. Now the Jam gets a tasty new carbon frame option with internal storage and buttery suspension. Can it toast the best full-suspension bikes on the market? Focus Jam is a 29er trail bike with 150mm travel front and rear New carbon front triangle gets I.C.S integrated down tube storage Flip-chip geometry adjustment on the shock mount gives high and low settings Entry-level model shares the same frame and costs £3,699 What is it about mountain biking that makes us obsess over numbers? If we’re not discussing travel, it’s geometry, sizing, reach, tyre pressures or some other metric to compare and contrast. Maybe it’s that some of us get as much of a kick out of geeking out over bikes as riding them. And while the business trope, “what gets measured, gets managed” helped drag us cave dwellers into the light, do we as riders really need to obsess over every single detail? Well, as the bike test editor at mbr it’s my job to sweat the details, and one recurring theme with the Focus Jam is that it’s a heavy bike. The brand new carbon Jam 8.9 is no exception. Tipping the scales at 15.64kg in stock trim, the latest 150mm travel 29er trail bike from Focus is still over 1kg heavier than the entry-level Specialized Stumpy Evo Comp that won our 2022 Trail Bike of the Year test. And while it would be easy to state that the Focus Jam is heavy and swiftly skip to the ride quality, curiosity got the better of me so I asked Focus why it’s heavier than most of its competitors. The response was both surprising and interesting, and it comes down to safety. All bikes have to pass a certain safety test and Focus merely ups the standard to have a higher system weight (bike and rider) than its competitors. So the latest Jam 2 e-bikes have a generous 150kg limit while the regular Jam is more conservative at 110kg. And with the trend for waistlines on a distinct upward trajectory, that’s probably a good idea. You don’t need to be a math wiz to figure out that if the bike weighs 15.64kg, then riders that weigh up to 94.36kg are in safe hands. But what if you weigh 70kg or less? Does that mean you’re riding a bike that’s overbuilt? Quite possibly, but the same is true of any bike that meets the same standard. Also we love to moan about the weight of bikes but we also hate stuff breaking and the painful truth is, you simply can’t have your cake and eat it. So while the carbon front end on the Jam 8.9 does save some weight over the alloy Jam 6.9, it’s only 250g as the down tube also needs reinforcing to support the cutaway for the internal down tube storage, aptly named …Continue reading »

Points forts
  • Plush suspension and good flex response from the frame provide plenty of traction. Shimano XT brakes and drivetrain performed without fault. Tyre combo is designed for aggressive trail riding in the very worst conditions. Internal frame storage is a bonus.

Points faibles
  • Would benefit from a higher rise bar or 160mm fork. Swapping the CIS stem is a total pain. Headset bearing seized up after a couple of particularly wet rides. Not the most responsive to pedalling efforts. PF92 Bottom Bracket.
