Looking at Bosch's information on Performance Upgrade 2.0: https://www.bosch-ebike.com/us/news/newfeatures-2026-05#footnote-1-2 On the U.S. website: Up to 600% support only up to 20 mph. https://www.bosch-ebike.com/en/news/newfeatures-2026-05#footnote-1-2 On the EU website: Up to 600% support...

The answer is... complicated. If the bike’s serial number registered with Bosch (i.e., the motor, controller, etc., with their specific ID numbers) hasn’t changed, and the bike’s manufacturer hasn’t suddenly changed after the firmware update, there shouldn’t be a problem. It’s a different story...

This is how the power limit works in the US version—at least in Bosch controllers. It provides active assistance up to just over 30 km/h; once this speed is exceeded, the assistance gradually decreases, and above 31 km/h, there is practically none. Worse still, this pattern also applies if you...

It’s quite simple. The service technician connects your controller (e.g., LED Remote, etc.) via a USB-C cable to a PC (Windows) running the Bosch DiagnosticTool 3 service software. This can be done on-site—in which case the technician performs the task on their own computer—or remotely—in which...

Yes, although I think they already cost around €50. But it’s still a good deal when you consider the price-to-functionality ratio. Only with the same software that was updated to the US version. You need to set the wheel circumference to half the current tire circumference. Unfortunately, this...

But it costs more than €35, right? Exactly.

Currently, all "tuning modules" for Bosch Smart engines are pointless. Not only are they expensive, but they are also generally unreliable – sooner or later, the Bosch system detects the module and reports an error. Why are these modules pointless? Because for a few dozen euros (currently €35 –...

Thanks. Well, that's the answer I was expecting. To be honest, I expected what I described earlier, because "removing the limit" as a setting of 64 km/h looked like reducing the wheel circumference by half. And now we have confirmation of this. The result is a reduction in the displayed speed...

He has written that: Hence my question, because maybe he knows whether the slider in Folw works or not in the version with the speed limit completely removed. He should know: And that question was mainly directed at him. I know that. If completely removing the speed limit would prevent me...

And now a quick question—if this is the removal of the speed limit, in Bosch Flow, can you set the assistance limit to a specific speed, e.g., 25/32/unlimited? For the EU version, the maximum is 25 km/h, for the US it is 32—does the limit slider work, or is it ignored? Personally, I would...

Definitely 32 km/h. And that makes sense to me, especially since you can set the maximum speed in Flow according to your needs. As far as I'm concerned, 64 km/h is double 32 km/h, which means the wheel circumference is reduced by half. Of course, this could be set in the software (not Flow, but...

I am currently reviewing this thread. I can confirm that some service centers in Poland are modifying Gen 4 and Gen 5 software to a version adapted to the US market, i.e., with a speed limit of 32 km/h (I wonder if the nominal power is set to 250W or 500W?). What's more, they claim that it is...

I received my Bulcan a week after ordering it and have completed my initial testing. I have some rather interesting conclusions, both positive and negative. Device installation. The device itself is quite small and fits easily under the engine cover. However, if you want to add other devices...

This is not a Bulcan problem, it is an ANT+ LEV specification problem. The ANT+ LEV specification does not include wheel rotation pulse transmission! After all, I explained EVERYTHING in my post.#113 -This is the specific feature of ANT+ LEV. It transmits LEV speed and distance, but does NOT...

Perhaps Bulcan (and all engines transmitting data in ANT+ LEV) transmits speed and distance information rather than wheel rotation pulses, and Garmin (and other companies) require this information, which represents the wheels based on GPS measurements, and use it to determine distance and...

I currently have a speed sensor on the front wheel and a cadence sensor on the crank. When I bought Bulcan, I wanted to get rid of these sensors and collect data from the Bosch motor. Bulcan, of course, does not have its own speed sensor, but transmits data from the motor controller, including...

Did you wait a long time for the delivery? I wonder (this is not mentioned in the manual) whether Bulcan supports the ANT+ eBike profile only for sending data, or perhaps two-way ANT+ Lev – which would make it possible to change, for example, the assistance level from the Edge screen. It is...
