More good Holiday news, not quite in the form of "free" hubs but cassette freehubs at least. We've now got two new rear motor options available that shed the threaded freewheel for a cassette freehub system, allowing you to take full advantage of modern drivechain components and the increasingly common 9, 10, and 11 speed gearsets.
The first of these is the tiny Bafang G310 geared motor. This is a small lower power hub like the G01 but with an impressive 11:1 internal gear reduction giving an even better torque to weight ratio. And best of all it uses a spiral sun gear that makes an almost completely silent and silky smooth motor when paired with our sinewave Grinfineon controller. Other features include a side cable exit, easy disassembly for service, integral anti-rotation washers, and excellent waterproofing.
The second freehub motor is a rear direct drive hub from MXUS. This one has a 30mm wide stator, so slighly more powerful than the 9C+ and a bit less powerful than the Crysatlyte 'H'. It has the same Grin customizations that you'd expect, with side axle cable exit, 0.35mm laminations for low rolling drag, internal temperature sensor, and fully sealed side plates with a statorade injection port.
Both motors are available in fast and standard winding speeds, fit inside standard 135mm dropout spacings, have disk brake compatibility, and are fully modeled on our simulator (See the G310's and MX3005/6). The MXUS motor also been thermally modeled with Statorade and Hubsinks options too.
We've got a limited number of each motor on hand now and we expect our large sea freight orders to be here in mid-January once these sell out.
