When you start to narrow your choice down, I would suggest that you ask the dealer some direct questions in relation to the replacement cost of the following items.
Front drive sprocket.
Any idler sprocket and bearing that may be fitted.
The rear mech hanger.
Rear suspension bearing and bush kit.
The reason for asking these questions, is that it might save you a nasty shock come service time, or in the event of a fall in the case of the rear mech hanger.
Also be very wary of the claims that are being made in respect of range, and watch out for 400wh batteries being fitted to the CX motor. It is not a good combination in respect of range.
