I visited the small Electric Power Bikes showroom and workshop last week. There is a large sign so it is easy to find opposite the entrance to the NATO base on the way to Chania airport, on the left just before the roundabout where you leave the main road.
The guy was very helpful and knowledgeable and spoke good English. There was a small range of bikes available, a mid-range mountain bike was priced at 650 euros inc all taxes, which was less than I was expecting.
They have an informative website www.epb.gr
which can be viewed in English.
I shall certainly be going back for a proper look and test ride when I am next over in July, and not in such a rush to catch a flight.
Worth a visit if you are interested in an electric bike to use on Crete.
