Actually I think by changing the wheel diameter in the controller setup you are throwing off the speedometer calibration . To check that get a GPS speedo app on you cell phone and test the speeds.
I have this same bike as you and love it. I also love the upgrades you have done to your with the fork and rear shock. Would you mind replying with the links you found them at? Thanks so much! I’ve easily found the limitations of this suspension. It really is an outstanding bike.
Riding on the highway is illegal where I live. Even if it was legal I still wouldn't do it.I have the same bike in camo paint and 1500 watts. Great bike ! I run 30psi for the hiway and drop it to16psi for the sand and dirt .. Small knobs on the tires dont wear as fast as big knobys. I think its a great commuter. I travel 12 miles a day on the hiway. (28mph)
