Same here. I am away this weekend with the TTXGP over here, should be back at it next week.
Oh man I want to see this motor being pushed a bit. Fantastic work so far. I hope you get what you want out of the build.
I'm interested to hear about your opinion about having a compact gearbox. Seems to me that we could get a much greater range of acceleration and speed.

Nice job you done here,
Why you dont add transmission? -for better acceleration and the ability to drive uphill, and most importantly, it saving a lot of battery energy.

Astropower... main reason for no transmission is no room in a little 250 frame.
As a rule the same performance benefit you can get from a transmission can be had by just using a bigger motor. The end result would weigh the same and give you about the same increase of power. BUT a bigger motor has fewer moving parts to brake and is simpler to install and maintain!
Colossus can run 20-30HP continuous with a good cooling system and their is signs showing it should take 50kw (67HP) for ~10 sec! Because of its efficiency maybe more but it will also depend on batteries and the voltage Splinter uses. Right now Splinter is running around 10hp or less. So once he ups the power he will have a fairly quick bike and hills should not be a problem!

This is Automatic Gear system.
I have this system on my Scooter, (see the rear wheel, that is not Hub motor)

i can tell you, that i got huge differernt when i turn off the gear and turn on the gear. and it save me space because it is hub gear wheel.
i can drive any place and any hill, with 180KG Load of two people without problem. with 1.2KW motor only (1.9KW Peak maximum i get in my scooter screen).

ok so it has been weeks and weeks. Most of this time has been at work (upwards of 70 hours most weeks) or sick, laid out all last week.
However I have managed to layout all the components how I want them, now to cut and mount them up in 1mm or 2mm aluminum.
IMG_20121105_203900 by Splinter, on Flickr
I also got some time to put on the new handle bars with switch gear and the Jozztek throttle.
It is starting to look really good, this coming week and weekend should have all the components fully mounted and my wiring loom starting.

looking good, did not read the whole thread, but a good tip on cooling (if you didn't do LC) is to sand (fine) down the face off the motor and maybe in between if it is made like the 80/100 + apply cooling paste, this will pull heat out of the stator and windings, this has helped tremendous on my Electro Ciao and will let the motor handle more power and run cooler

I have about two weeks to get the bike ready for the Canberra EV festival on the 1st December.
Man do I have a lot of work to do.
Ok first I have the gauges on the "dash" and the wiring started.

I have also setup the mounting for the controller. This will go under the tank along with the BMS, DC/DC converter and low amp high voltage fuses.
Here is a shot of the controller in the mounting bracket.

Quick update with all the work I have done this past week to be ready for the festival.

To be ready for engineering requires the last of the 12volt wiring loom... and well that is it.

Looking very neat Tony!
See the good thing about taking 3 years to build a bike is that it will look really good by the time you're done. You really can't rush these things. The way all of your components fit so neatly in the bike is a testament to your patience
Have fun at the Canberra EV festival!

Chris, thanks a lot I am really happy with the fit and finish. There is a bit yet to do, I have blown the seals on one front fork (totally my stupid fault) and I have to get the 12 volt completed but I am hoping to have the whole thing going and registered by the end of January.
Just a couple of shots before I put on the chain and make sure it all goes still

Good stuff Tony. Keep cool eh? We've had more than enough heatwave over here.

Will you be able to register it with red HV wiring?

No I won't, the red wires were from the bench setup for he motor. My orange HV wires are back on. I have to change some of the other wiring for the new controller as well.Gregory said:
