Another problem with the e-bike controller is that it is not compatible with an R/C radio signal. _________________ Australian 2015 Featherweight champion

I am not sure what value you are trying to calculate. Back EMF depends on the motor's inductance and will be different for every motor. Generally, the back EMF will be higher than the supply voltage. _________________ Australian 2015 Featherweight champion

In QLD at least:
TEA Transmissions
https://www.tea.net.au/Home.aspx
They can be a bit pricey as they generally stock high quality industrial gear. They have a good web site and reply to emails promptly.
Smallparts
http://www.smallparts.com.au/
. Possibly the world's worst web site, but they have tons of useful bot bits and usually at OK prices. They have a shop in Capalaba West but don't have much of their stock on display there.
I use both these company's on-line stores and shipping should be cheap for you. _________________ Australian 2015 Featherweight champion
