Decoy assist top speed less than 20 mph

My assist shuts off completely at 18 mph. Seems like a gyp to not get right up to 20 mph.

Wheel diameter can be changed to compensate

It's been re-set with Shimano assistance. Decoy speedometer is consistent with Garmin 520+. YT tells me 18 mph shutoff is spec. I can't believe such poppycock.

I just googled this 18mph cut-off. Seems to be all E8000's motors. Pivot shuttle, Commencal,etc.,

Does STunlocker have the ability to adjust wheel size? My bike seems like I'm going a bit slower than the Shimano display says.

Yes it does.

Change the value by 10% and in theory you will gain 10% speed limit

Or just change region to USA with STunlocker

The Shimano motor decreases the level of assist as you get close to the limit, the idea being that you dont get a sudden drop off as you hit the limit.

Be aware that if you have a problem with the motor, and need to get it warrantied, but have used a third part app to tune it, then you will need to flash the software back to stock before sending it off, as they can tell through the diagnostic software if it has been played about with, and may not warranty the motor if they think it has been derestricted.

IMO if you really want to look at derestricting the bike, then something like the Badass box is a better option as you dont have to change the software, or connect anything to the motor, as it simply tricks the speed sensor it not thinking you are going half as fast as you are, though of course this means the speed displayed won't be accurate, not the distance travelled.

Do you have a badass box on your bike ?

i had one for a bit, but I found it reduced the range as you are always using the assistance, so took it off. I am not really so fussed anymore about the limit
