I'm testing a 2016 Ui5 Magnum from a private party with 600 miles on it and I have not been able to determine what's it worth. Does anyone have any idea what a fair price for this bike would be? I ride a Surly LHT with a 500 watt E-Rad mid drive kit and it has 3000 miles on the kit with no problems. I have learned there is a lot of differences between mid drive and rear direct drive hub motor. I'm looking for a step thur.
