Thanks to all for the support. This is such a great community!
General Condition
I haven't ridden a bicycle in 35+ years, so my knowledge on what to look for and to make a fair judgement on the condition is rather limited. I will check for the obvious scratches, dents and the like.
LUBRICATION
I will verify that items like the chain, derailleur, etc., are clean and lubricated.
SCREEN /JOYSTICK
I will check that the screen is functional (including the backlight) as well as the joystick. This seems to be one of the more common failure points. It is my understanding that the display will also show the software version. I am not sure how to determine if it is the latest version though.
BATTERY
I can check that the battery has a full charge and reads 100%. I've read some batteries will not charge to 100%. There is no way short of taking it to a dealer to determine the overall health and number of charge cycles. Based on age and miles, I hope that it has been connected to a charger to prevent a full discharge of the battery. I am not sure I would believe the seller if they told me maintenance charging had been performed. I will take a test drive to see if the battery is draining abnormally. Other than that, this is the most difficult part to determine condition.
MOTOR
I will listen to the motor while riding to verify that it is silent (no rattles). I will lift the rear tire while the Turbo mode is engaged to see if the wheel spins and requires calibration.
WARRANTY
Specialized warranty terms indicate that it is NOT transferrable so...
CHAIN GUIDE
Looking at the pictures, it seems that the chain guide was added in the 2016 Turbo S. I will have to install one myself (suggestions as to brand and model?). Maybe my LBS can help there...
TIRE / WHEELS
I'll flip it over and spin them to check TRUE. There should not be any wobble.
BRAKES
I'll check that they work and aren't leaking. Should I be worried about any squeaking?
PRICE
He is asking $3000
Thanks and regards, Frank
