The venerable 400 and 5300 motor series that got so many enthusiasts started on ebikes has now been formally discontinued by Crystalyte (about time some would say!). The good news is that Crystalyte is now producing a new HS/HT motor series that is based on the same efficient motor construction style as Nine Continent, but with much better mechanical fit for bicycle and disk brake compatibility. For a more complete summary of the improvements see the postings on the Endless Sphere thread here.

We sampled these motors in January and have put them up on our simulator. We expect to receive our stock available for purchase in mid-July, and these will be the first bulk batch of sensored HS/HT 35mm motors delivered in North America, so that they will be fully backwards compatible with all the sensored motor controllers.
