Edit: Justin is reporting that his initial order of these have a 30mm wide stator, and the spoke flange diameter is 210mm, so the outer shell is approximately 22mm smaller than the common Crystalyte H35 (@ 232mm), for reference, one inch = 25.4mm
TDCM is currently best-known for their torque-sensor BB-crankset. At the Interbike 2014 in Las Vegas (Sept 9-13), they had a prototype of their new hub-motor. The rep was not fluent in English, but the hub has a 5-speed IGH built into the center of a direct-drive hub-motor, and the rep said that they are working on a 7-speed IGH that will retrofit this model.
Since it doesn't need to allow space for a 7-speed gear-cluster, the stator has the option to be fairly wide, and 45mm would easily be an option for this style (Crystalyte is still making 40X's for ebike.ca's "stokemonkey", with 40mm wide stator). I was told they will be available for purchase in October, and I would definitely use a full-suspension frame on this, to help avoid taking a chance on breaking axles and spokes. [The axles and spokes may be very strong, I'm just saying there is no road data published yet]
He said the proprietary disc brake is a one-piece (no separate spider), with a non-standard 4-hole interface (seen in pic).
