I just got off the phone with
Lectric. Their customer service is really good. I got the "Press 1 for..." and I'm thinking oh great this is going to be a long wait with some terrible hold music. Nope like a minute later a real person answered the phone!
He said it was just how the bike is and there's not way to vary or reduce the power. The pedal assist levels are based on speed so it's full power assist up to whatever speed that pedal assist number is assigned to. At least I know now that it's working as intended.
I should have asked if all Lectric bikes are that way but I forgot to. I suspect it's not all because the XP Lite has a different motor and controller setup than other Lectric bikes. I'm thinking it was a cost saving measure and I'm okay with that because it's a great bike to get around town.
