eMax Reviews

Does exactly as advertised. The developer makes it clear the firmware on my EP801-RS would not allow removing the speed limit, but now my motor functions at the full 600W power instead of 350 thanks to eMax.

Major kudos to the documentation produced my this developer. I would consider buying a full license to continue supporting the dev.

The only viable option for tuning a shimano EP801 motor in the market today. Markus provides top notch before and after sale support and I couldn’t be happier with the product and support I received.

eMax used is a little rough on the UI but extremely functional. In conjunction with the free desktop application it completely transformed my bike and unlocked some serious power potential.

Easy to use, worked great to "derestrict" my 2022 Orbea Rise with the EP8 RS motor. Makes it feels like a whole new bike and cured my new bike itch for at least another month!

Have been using this he PC version, and eMax is the perfect complement.

I previously used another app to unlock 2 e8000 units and it was frustrating and complicated to run through the process. I managed to complete the tasks. I attempted a 3rd bike and the software crashed no less than a dozen times before I gave up. Each crash resulting in a tedious task of recovering the Shimano software to restart the process. Each crash being so difficult to deal with I was worried about rendering the drive unit permanently inoperable. Assistance from support was of no help. I then found the this app software and installed that with no trouble at all. Not only was it easy to install but the software must be engineered better than the competitors as power delivery is smoother, not jerky, especially in the boost mode. I am buying another this app license for my third bike and uninstalling the other unlocker and intend to do the same for the 3rd bike as well. Markus, the developer of this app, is very gracious and available for any questions you may have. Through several emails with Markus I discovered he really likes what he does with this software, this app is not “just a business”.

I have unlocked my 5th DUE8000, a Bullitt cargo bike. All the above, still applies. Great product, great developer to back it up. I’ve never had, even close to the response to my inquiries made for app info. Thanks Markus

Works exactly as described. Need to download eMax first, pay one dollar. Once you download eMax and connect to your bike and send info to this app. The response time was really fast. They Sent over the access code, downloaded it and it worked awesome! I have not made any changes to the power or torque settings. I just changed the wheel size and bike does well over 30 miles an hour!

I had problems with another company that I had to plug-in another module. The motor would stop working from time to time. Very frustrating. The this app has works flawlessly on my bike and my friends bike. Highly recommend this upgrade.
