Bosch has announced a new software update for selected e-bikes, giving riders even more control over power delivery, ride data, and tuning options.
Which bikes does the update apply to?
The Bosch update, announced in May 2026 and available through the eBike Flow app, applies to selected models including the Trek Rail Gen 5, Trek Powerfly Gen 5, Trek Powerfly FS Gen 4, and Diamant Zing & Suvea.
It also applies to selected Cube bikes fitted with compatible Bosch smart system motors, including bikes from the Stereo Hybrid ONE22, Stereo Hybrid ONE44, Stereo Hybrid ONE77, Reaction Hybrid, Kathmandu Hybrid, and Nuride Hybrid ranges.
Riders can install the update through the eBike Flow app, or via the Bosch Diagnostic Tool in markets where the app is not supported.
More Power, If You Want It
The update gives riders the option to tune their assist modes up to 120Nm of torque and 600% motor support. These bikes will continue to come with 85Nm as the stock setting, which remains the best all-round balance of power, handling, and drivetrain longevity, but the update now gives riders the option to unlock more assistance if they want it.
Expanded Tuning and Better Ride Data
Bosch has also expanded tuning options within Extended Boost mode, giving riders more flexibility in how the bike responds on the trail.
Another useful addition is the ability to view ride metrics from the app on third-party devices such as Apple Watch and Garmin, making it easier to keep track of performance and ride information across the devices many riders already use.
Introducing Trick Check
The new update also introduces Trick Check, a feature that automatically senses and measures jumps, wheelies, manuals, and stoppies. Riders can see metrics such as distance, duration, height, and angle, adding another layer of fun and ride analysis for those who like to push things a little further.
If you ride one of the eligible Bosch-equipped Trek, Diamant, or selected Cube models, this free update gives you more choice in how your bike feels and performs. Keep the proven 85Nm setup, or tune things further to suit your riding style.
