Are you looking for high torque, such as for quick startups? Or are you looking for fast speeds?
How much power do you need, and what is your weight limit? (and budget, if any)
Personally, for quality control and manufacturing consistency / design, based on the ones I've seen the insides of (and held in my hands), compared to all the other motors (especially Crystallyte
) I've seen the insides of (and sometimes held in my hands and used), I'd go with QSMotors, such as the QS205-40H.
Unfortunately it weighs another half again what the TC4080 does, but I would bet that it can handle at least twice what their power rating is, for long bursts, because of the extra thermal mass. Not sure if the TC could (being lighter). I don't have a cromotor to compare it, but others have said that to simulate the QS205 you can start with the cromotor in hte grin simulator.
(also, if it matters, the TC motors "save weight" by removing most of the spoke flange, so if you ever have a failure of a flange segment, you can't just drill a new hole nearby and put new (longer) spokes in there to save the wheel...the QS is a typical full-circumference flange. This also means that the QS can be drilled for smaller spoke holes for typical bicycle-rim-sized spokes of 14-15g (13-14 max), if you don't want to deal with spoke washers for the oversized (12g and up) holes pretty much every hubmotor seems to have.
