Put an order in for the M20 with my LBS (can’t actually order one yet and it’s not even the pre order, it’s the pre order, pre order!!) and have put in for a range extender but I’m looking for some real world reviews on battery range to see if it’s even required. For the record I’m 88kg and a smidge over 6ft tall so will be riding, eventually, a large. Thanks in advance.
