I've been swapping older Bionx I2C 250 and 350 watt motors into 700C rims as I look for the best solution for a long distance touring ebike.
I have an I2C 250 watt Bionx motor that has a great high speed winding, but it doesn't have bolt holes to attach a disc brake rotor. The 350 watt motors don't like to give much support at or above 20mph, even when driven at 12S or 14S instead of the 10S they were designed for. The 250, OTOH, really likes to run at speed when fed higher voltages. It has a no load speed of 35 mph at 46.5V whereas the 350 watt motors have a no load of 27 mph at the same voltage.
Would like to buy a disc compatible I2C 250 watt Bionx if they made one, I just can't remember if they did- anyone else know?
Maybe another idea would be to rewind the motor myself, but have never opened a hub motor, and would need to locate a 3-jaw puller capable of handling an 8.5 inch diameter hub.
Please share any thoughts or ideas if you have them!
