'Dongle' for a Trek Powerfly 7 e-MTB

[John from Connecticut]

I ride a Trek Powerfly 7 MTB( Class 2 - 20MPH Max ) and would like recommendations on a speed 'dongle'. I ride exclusively rails to trails and limited roads
and being able to hit 23-24mph would be a joy.... The new Trek Police Powerfly is exactly the same bike and it's a Class 3. I contacted Trek for a mod, they said contact Bosch. My LBS contacted Bosch, they offered no mod except "Replace the motor and update the firmware"...I won't be doing that anytime soon. : )

Thanks in advance,

John from CT

I have an unused Bikespeed RS, which is perhaps the best dongle out there.
Let me know if you are interested.
