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

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.

Gears and Drivetrains

Hi Guys Smile

Just wondering if you know of a good place to buy Gears and drivetrains?
are there any physical shops in Brisbane?

- Geoff

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.
