motors and controlers from Oatley elec. Aust. experiences?

[syncro]

Hi All,

New to the forum and thinking of building my first e-bike, a seperate motor driving through the gears, I've got the equipment to make brackets ect. I've been a bike mech, raced road and track and have been messing about with bikes for most of my life.

I'm wondering if anyone has used the controlers and motors on offer from Oatley electronics? www.oatleyelectronics.com/ are these OK?

I'm in the Yarra valley 65K's out of Melbourne Australia.

Steve.

those motors are way overpriced, i bought mine on ebay, this one is the same model as their 500W ones but is the 750W version and only $75 including shipping. http://cgi.ebay.com/NEW-750-Watt-36...ryZ75210QQssPageNameZWDVWQQrdZ1QQcmdZViewItem, i dunno how much it will be shipped to AU though.

The geared 250 watt motor is a rippper for the price and peaks at close to 600w from memory. It is the same motor on the new Curries (kmart etc.).
A few of us have built bikes with them and one of the forum members is testing to see how far you can push the voltage without meltdown of the motor.
The Oatley controllers are good but won't take over volting from others experience.
I was running a low chopper with one on the b/b and had no trouble sitting at 40+kph with pedalling and getting above 50 wasn't to hard.
I wish they would bring the geared 500 and 750 watters into Australia.
The ungeared ones would require substantial reduction to provide any torque.

thanks for the replys, the shipping would be the killer on those ebay motors , could easily double the price. Geebee, thats is exactly the sort of info I was after! I was thinking it looked like the Currie motor but couldn't quite make a comprison from the pic's, on the web. I liked the idea of it having internal reduction too, do you know if the reduction gears are steel or plastic?

BTW I like the streamliner in your avatar, reminds me of the Mochet Velocar's, I've been looking at 'bent trikes lately I've wanted one for years, planing to build one soon. trike + elec assist = fun!

The gears are steel, a bit noisey but bullet proof.
The avatar is my daily ride, not electric though.

I thought I'd better ask this here, rather than in Geebee's solarbbq thread. Would the 250W geared motor be limited by the Oatley 350W controller as it peaks at over 350W or is the rating on the controller continuous and not an indication of the max power it can handle? Also, does anyone know if the thumb throttle can be used with the 350W controller?

Their controller is rated to 30 amps maximum the 350w is probably a touch conservative.
About the thumb throttle prehaps ring/email and ask as the pdf 's for the 2 different controllers show a different resistance for the pot version of the throttles, so I think one would have to assume that they may alter the full range voltage, whether this would have a noticable effect...?

OK, thanks for the info. 30A is a lot more than I was expecting so that's a nice surprise. Regarding the throttles, I emailed Oatley about a week ago, but I haven't got a response yet. I did notice that the pot setups were different so we'll see what they have to say.

It doesn't really matter though, I'm just not sure how the twist throttle would work with twist grip gears.
