It’s no secret that the current Focus JAM² is one of our favourite electric mountain bikes here at Flow. As the lightest e-MTB we’ve ever ridden, the JAM² has done a bang-up job to stand out from the crowd with its smaller battery pack and neatly integrated chassis. So when we heard that Focus was going to be releasing a new Bosch-equipped version for 2020, we were a tad concerned that the German brand might mess with some of the key ingredients that have made the JAM² such a ripping bike to ride.
Turns out we needn’t have worried, because the 2020 Focus JAM² will actually be available in two models for this year. The existing Shimano STEPS model will carry over unchanged, while Focus is bringing out the new Bosch-equipped JAM² as a new and secondary option. As we found out though, there’s a bit more to this bike than just a different motor.
Mo’ Torque, Mo’ Battery
For a start, the Bosch-equipped 2020 Focus JAM² has a much bigger battery pack. It’s still integrated neatly into the downtube, but instead of the compact 378Wh battery used on the Shimano models, this fella gets a girthy 625Wh unit. That adds considerable range, particularly for those who are into big days out in big alpine territory.
The new Bosch motor system also delivers a touch more torque – 75Nm over the Shimano STEPS E8000’s 70Nm. As most folks will have gathered already, Bosch is back in a big way for the 2020 model year, having unloaded its 4th generation Performance CX Drive unit to the world just a couple of months ago. A number of bikes have gotten on board with the new motor system, including the 2020 Trek Rail that Mick recently tested. There’s a load of fresh tech lurking inside that makes it smoother and quieter than its predecessor, but the big news with the new Bosch Performance CX unit is how much more compact and lightweight it is. And that gives brands like Focus some serious flexibility to change things up.
Holy Chainstay Length Batman!
At first glance the 2020 Focus JAM² looks pretty similar in shape to the Shimano-equipped carryover model, but there’s actually some key differences that mean it’ll ride differently. The first is the chainstay length, which on the current Shimano JAM² is a very roomy 470mm. On the Bosch JAM², that comes right down to 427mm. That’s 43mm shorter, which is a huuuge difference!
Focus has also increased the reach measurement of the Bosch JAM² considerably. On a Medium frame size for example, the reach increases from 430mm to 445mm. The head angle has also slackened by half a degree to 66°, while the seat angle has been steepened half a degree to 75°. While the front wheel now sticks out further in front of the rider, overall the wheelbase is a bit shorter on the Bosch JAM², which is due to the dramatically tighter back end.
Flip That Chip
Focus has also added in a clever offset chip at the rear dropout to offer in-built wheelsize flexibility. The JAM² is available in both 29in and 27.5+ versions, and the current Shimano version employs a unique back end for each wheelsize option. The Bosch JAM² actually uses the same frame between the 29in and 27.5+ versions, but relies on a simple flip chip at the rear to alter the rear centre length and BB height simultaneously when switching between wheelsizes.
Alloy Only…For Now
As of right now, Focus is only offering the Bosch JAM² with an alloy frameset across two spec levels, with both 29in and 27.5+ wheelsize options. However, given how hard Focus has been pushing in the e-MTB segment over the past five years, we have a sneaking suspicion that higher-end models, and carbon fibre frames, are very likely to follow.
Then again, perhaps Focus will keep the Bosch models in alloy, and keep the higher-end carbon models with the Shimano STEPS motor? Time will tell on that one. In the meantime, while we fan the flames on more viscous rumours, here’s a closer look at each of the new Focus JAM² models.

Focus Ain’t Done Though – Here’s The THRON²!
Alongside the new 2020 Focus JAM², there’s also a brand new model called the THRON². Sharing a similar shape to its bigger sibling, the THRON² is also built with a 7005 Hydroformed alloy frameset, the F.O.L.D suspension design, and the new 4th Gen Bosch Performance CX Drive unit. But whereas the JAM² is a 150/150mm travel bike, the THRON² steps down the suspension travel to 130mm front and rear, while utilising slightly less aggressive geometry and components to produce a more general all-round trail bike.
Focus expects the THRON² to be more suitable to beginner and intermediate riders, who are perhaps looking to get their first e-MTB, or are trying mountain biking for the very first time. With that in mind, the THRON² will be kicking off at $5,499 for the 6.7 model, which is a mighty impressive price point given the Bosch powerplant lurking between the pedals.
