New E-Bike Owner - Trying to get it just right

[MahatmaAndhi]

Hi all,

I'm new to E-bikes, but have many 'regular' bikes, so I converted one with a TSDZ2B(T) mid-drive kit with 48V/15Ah downtube battery.
I've put this on my Carrera Subway Two - not the best bike in the world, but I like how it looks.

I have a VLCD5 screen and I've managed to find the hidden menu. I've managed to change from kph to mph and can see the settings for the wheel size and speed cut-out etc.
I've set mine to 16mph and wheel size to 28 (there's no 27.5 option), but whenever the 16mph limiter is on, it'll cut out at about 10mph on a flat surface.
If I take the limiter off, I can pedal to 20+mph and still hear the motor whirring away. I can't seem to find the sweet spot.

Any ideas?
I've got the bug now so I'll be trawling the forums for answers to questions I'm yet to ask.

Thanks

I don't know the system, but maybe the limiter is still in kph even though the display is in mph?

Even if you have speed display set to mph, the limit is usually in kph. Therefore you need to set it at 25kph (about 15.5mph).

16kmph is 10mph, so yes, set it to 25.
