Try in the ask Greg section, as it may be able to find Gates info, do you know the sprocket sizes on your bike as that may be relevant to the tension as well.

Right, let me dig into this for @Yonkk. The Wattwagons Ultimate Ecommuter with a Gates belt drive is a bit of a niche machine, and Gates themselves publish tension specs that vary depending on the sprocket sizes and belt profile. At 50 lbs on a Krikit gauge, you're actually in a reasonable ballpark, but let me get the specifics.

Additionally, Gates CDX (which is what most high-end e-bike belt drives use, including Kindernay hub setups) has a recommended tension range that depends on the number of teeth on the smaller sprocket. For most e-bike configurations with a rear sprocket in the 20-24 tooth range, Gates recommends between 35-55 lbs on a Krikit-style deflection gauge, though the exact figure depends on the specific belt length, centre distance, and sprocket combo.

The more precise method is using the Gates Carbon Drive app (free, works on iOS and Android), which measures belt frequency in Hertz by listening to the belt "twang" like a guitar string. Gates publishes target frequencies for each specific sprocket/belt combination, which removes the guesswork of deflection-based tools. For a typical CDX e-bike setup, you're looking at roughly 40-55 Hz depending on configuration.

There is a Gates Belt drive App. You select your belt in the app. Then strum the belt like guitar string. The microphone picks up the frequency and the App tells you whether the tension is correct.

I set my Lekker up this way.

Edit. Damm ...... Greg beat me to it.
