I just perused this forum to look at the Outrunner posts/questions. Most of what I found was not favorable, but it was almost more than one year old. Has anyone done a brushless outrunner conversion in the past few months? I have read of people have favorable results on other forums. I am not trying to start a war by asking on this forum. Instead I am trying to get a balanced view before I plunk down $$$ I am hoping to do a conversion on a 24 pound folding bike and I would like to keep the weight down as low as possible so that I can keep the advantages of a folding bike.
Hello everyone much smarter than me in things with the volts and the amps and things.
First, some quick background:
I've built electric cars before through a highschool competitive team, but I was mostly in charge of frame structure, weight reduction, and aerodynamics. We used a 24 system with an etek motor and curtis controller, but we used simple Anderson disconnects as our on/off switch, and had nothing in the way of a precharge resistor (a shunt for a meter and brake lights, a fuse, and a throttle were everything else).

Howdy Everyone:
Allow me to introduce myself. I'm Colonel Monk, and I've been lurking here a little bit for a year or more.
I'm doing my own EV based on a chinese bike rickshaw. It's 3 wheeled, and weighs about 150 lbs unladen. It need's only to travel 5-10mph, nothing faster, as it's domain will be the dry lake bed at Burning Man festival in Nevada.
I've decided on an etek-style brush motor (one of the cheapies - Manta I believe) and so I'm now moving on to figuring out what controller to use, etc...
Hello...
I finally have it together and running great except for the instability in cornering abruptly.
Was wondering if anyone could suggest any options to keep all three wheels on the ground. I
thought if I moved the shock absorbers to the outside of the rear wheels; hence changing the
shock mounting location to the frame, would stabilize the high center of gravity?
We're back! I can't believe it's been almost a year since we last tinkered with the Wattana bike, sorry life got in the way. Here is the latest update to the Wattana website. It is a page on how we are attempting to mount the Mars ME0709 DC 72 volt 125 amp motor on this red 2001 Suzuki Katana GSX600F. No excuses but the website is hosted by Comcast and uploading files and pictures using their Personal Web Pages file manager is horrific.
For our high school senior project, we have created a bamboo electric motorcycle. This project has been extremely fun, challenging, and time consuming; this is not something you can do over a few weekends. The end goal for us was to create a working motorcycle with a bamboo frame and an electric motor, as well as to create an Instructable.
The main stages for this project are:
Setting your goals for distance and speed and creating a budget.
Researching and ordering drive train parts.
Testing the drive train
Creating a model in SketchUp
Obtaining and heat treating your bamboo.
Hacking apart your donor bike
Tacking the frame together
Epoxy-ing the joints
Creating mounts and attaching the drive train.
Wiring.
Final parts and safety checks.

I'll include pics when I am done with the body work. This is my first project and I have overcome the following:
Never did any project anything like this before.
Minimal welding, electrical and moderate automotive skills.
Cost of project-just over $4000- I am not employed, time spent persuading my wife.
I have no real work space, just a 6x8 shed.
I have limited tools. I did not really plan the battery placement, I mounted the motor first and started low with the batteries and these optimas go all the way up to what used to be a gas tank.
