Shimano E-Bike motors settings and information

Features & Capabilities

STUNLOCKER is a powerful Chrome extension designed for Shimano E-Bike motors including EP801, EP8, EP6, E8000, and others. It connects via Bluetooth, enabling users to access comprehensive e-bike information such as total distance traveled and battery health. Additionally, it allows customization of assist settings and gearing types (mechanical or electrical) along with chainring size adjustments.

The extension offers convenient presets for quick bike setup and supports multiple advanced features depending on the bike’s firmware. Note that newer EP801 and EP6 motors currently do not allow changing advanced settings like region or circumference via Bluetooth, which applies to other latest firmware versions as well. STUNLOCKER streamlines the management of Shimano E-Bike motors for enhanced riding experience.

User Reviews

STUnlocker is praised for its powerful tuning capabilities, excellent developer support, and ease of use compared to the official Shimano eTube app. Many users successfully derestrict their e-bikes and customize assist levels with good results. However, some common issues include the need to downgrade firmware to use features, extra costs for premium licensing, complex setup steps, and occasional connection difficulties. Overall, it is highly recommended for users seeking enhanced control over their Shimano e-bike settings despite these minor challenges.

Pros

Highly responsive and helpful developer support and communication.
App offers rich and detailed tuning features not available in the official Shimano app.
Works well for derestricting and customizing bike settings such as speed limits, wheel circumference, and motor assist.
User-friendly interface with clear instructions and good documentation, making it easy to follow the setup process.
Fast Bluetooth connection compared to the official Shimano eTube app.

Cons

Requires firmware downgrades or old firmware versions for full functionality, which can be risky and tricky to manage.
Premium license is necessary to unlock all features, representing an additional cost beyond the initial app purchase.
Setup can be fiddly, involving loading unverified APK files and manually transferring .dat files.
Hardware requirements for some motors (e.g., EP8) can increase complexity and cost (e.g., needing interface boxes).
Connection process is not always straightforward and may require turning the bike on and off or disabling Wi-Fi for smooth operation.

Recent reviews

Perfect app for the e5000, update ur assistance amount and disconnect the app from the bike, massive difference. Only downfall for the e5000 is once you switch the bike off, the default factory setting will kick back in when you turn it back on again. Ide rather be able to tune my bike than not tune it at all so very useful app very good communication from the apps creator, probably the best app for steps. Can't wait to try the lincese next see what that unlocks.

E035 error after following instructions and firmware update loaded onto bike successfully. Basic app works but premium involves loading an unverified apk file (Android) then adding .dat files within filesystem. Fiddly setup and ultimately didn't work. EP8 RS motor. --== update: thanks for the feedback. haven't had time to tinker with it - will update soon ==-- UPDATE: Finally got around to troubleshoot again. Emailed the developer of the app and resolved it. Quick response. Kudos.
