I work at an ebike shop and a customer brought in a custom built ebike (his sons bike who passed away) that had a bad display causing it not to turn on. After replacing the display, the bike turns on but will not exceed 10 MPH. Also the speedometer doesn't work nor does it show power output. I am unclear if the speedo and power output worked prior to the bike coming in. The display is a 750C, has a 72V battery and I am unsure of the size of the direct drive motor. The controller has no stickers or markings to show what brand or model. I have changed all the advanced settings to essentially unlock the bike and still no joy.
Does anyone recognize the controller brand?
