Hello guys
I'm just waiting for 2 of these motors to be delivered, one is for a 20" fatbike the other is for a 700c tourer project with a custom 7005 frame.
I'll try both the sine and the square controllers, with a pair of the possible displays.....
Indeed these 2speed motors are too wide (both the rear and the front versions). only the non disc versions can fit the standard 100/135mm.....
I asked for a slightly modified motor for the 700c, the standard disc/multispeed motor is 146mm, I asked XD to file and extend a bit the threads on the drive side, so that I can reach 137mm, obviously at that point, the space for a standard multispeed freewheel would be not enough, but with a longer nut I can get again the original 146mm dropout, and I'm anyway confident about to fit to the 137mm, with or without mods, one of the zillions freewheel units that are lost in the shop, ....
The 700c motor is wound for a 24" bike, this bike is ready from months but is still waiting for a reliable motor to be used at >280rpm, we will see if the XD 2speed could be the one. A 25-30kph limited system in a 13Kg bike (9s4p 18650 + 3Kg motor included) is a non sense for me, since I can reach and maintain that speed without assist no problem with this bike.....
I hope that this motor, with the 2 speed would be able to survive the tests, than, eventually, I may decide to weld the frames with slightly wider Dropouts, so that the 146mm could fit in any case.....
I'll let you know all the details and will post pictures when I'll really have my hands on them.....
