NEW 2019 Bosch Electric Bike System eMTB Updates

By Martin Brown on May 2, 2018

Every year Bosch eBike Systems evolves its product line up. For 2019 Bosch offer new features for its eMTB community based on rider feedback. Let’s look at the new features.


The great thing about the Bosch eBike system is that it’s fully updateable. This means the system is totally futureproofed, where current users can have dealer updates to their existing electric bikes.

Bosch eBike UpHill Flow Trail 2019

Let’s face it, the Bosch Performance Line CX is pretty much one of the best systems on the market for its punchy power, smooth torque curve and new features like the eMTB mode.

In fact, Bosch actually won the Design & Innovation Awards 2018 for their new ‘Uphill Flow Trail‘ where they used expert trial builder Diddie Schneider to offer a new trail which actually flows uphill specifically designed for eMTBs & these features.

So what can Bosch possibly expand on? Well, based on rider feedback they have made certain improvements to the system itself. We’ll delve into a little more details about these:


New 2019 Bosch eBike Features Include


New Update For Short eMTB Crank Arms

Most riders run regular length cranks (170-175mm) but on an eMTB you tend to tackle harder climbs and the electric mountain bike allows you to navigate up rocks/obstacles etc.

Bosch eBike 2019 Update For Short eBike Crank ArmsWith full-length cranks, pedal strikes become more apparent. This means many riders have been fitting short Bosch eBike crank arms (165-150mm) which allows more ground clearance for more adventurous riding.

The trouble with just swapping the cranks is that it alters the feedback the drive system gets. Which in turn alters the output of the motor assistance feel, torque curve and in particular the characteristics when in eMTB mode.

For 2019 Bosch introduces software updates via a Bosch eBike dealer, who can program each bike to suit the preferred crank length. This adapts the progression curve in eMTB mode and also offers increased support in Tour mode, offering maximum power up-hill.



New Faster Walk Assist Operation

Yes, eBikes are made for the climbs, but every now and again you want to use the walk-assist when beside the bike for navigating obstacles or manoeuvring the bike up steep slopes.

Bosch recently updated the walk-assist button, as it was smaller and more difficult to hold underneath or above the controls. Now you simply press the ‘Walk’ button and then hold the ‘+’ button within 5 seconds to activate it. It’s easier to do with gloves on and more natural to hold this way. We do know that they are extending this 5 second activation time by a few seconds soon to make it easier and for users to navigate the two buttons in tandem.

Bosch eBike 2019 Update For Faster Walk Assist ButtonThe current walk assist is good, but some riders have said it lacks grunt.

New for 2019 Bosch offer a software update to fix all of this. Now with improved use of the gradient sensor, the walk-assist can adapt to changes terrain in both steepness and obstacles.

The walk assist, automatically adapts to the slope it’s on offering the rider full support where it’s needed most.

The new more powerful walk assistance enables sharp increases in walking speed to be mastered more easily with your eMTB. A new application ensures optimum power transmission – even on electric mountain bikes with short cranks.


What’s Next?

It’s an exciting time for Bosch as they continue to dominate the market & react to rider feedback. No doubt they’ll be a few more updates coming very soon. We also know that up until now the eMTB mode comes as standard as part of the latest bike firmware update. This is not optional, but in July the dealer diagnostics will give the option to turn it on/off.New 2019 Bosch eBike Electric Bike System

It’s important to note, as mentioned above, all of these Bosch eBike updates will come as standard on 2019 Bosch electric bikes, but is also completely update-able onto previous model years using the Bosch Performance CX motor.
