    19 new 100 mile range electric cars announced

    http://www.time.com/time/business/article/0,8599,1847544,00.html?cnn=yes Looks like high gas prices may have brought the full electric car back from the dead, at least in Europe. Wonder if we'll see any of them here in the US though.

    new Ecrazyman Infineon controller-BMC wiring?

    I got the new Infineon controller today from Hong Kong and want to hook it up at 48V on a BMC geared hub motor from EV-tech. I included some photos that show the wires. Anybody have a cross reference wiring diagram that goes from this controller to the BMC? Also, what are all the wires for...

    Toyota's new electric powered people mover

    This has to be the most pathetic thing I have ever seen. This is the best the minds at Toyota can come up with? 3.7MPH and a 3 mile range. http://news.yahoo.com/s/ap/20080801/ap_on_hi_te/japan_toyota_robot_2 I don't think Segway has anything to worry about.

    anyone ever convert a downhill mountain bike to electric?

    From time to time I search for free ride or downhill mountain bikes on ebay, and can't help thinking what a cool electric ride one of them would make. With their massive brakes, tons of suspension travel, and indestructable frames, they are pretty much like off road motorcycles without the...

    E-crazyman conroller upgrades and BMC hubs

    I have seen a lot of activity here recently on trying to get the e-crazyman controllers to work correctly with Kolmorgon and other high rpm motors like the BMC geared hub motors. I would really like to run one of those on my bike with EV-tech's geared BMC hub. Have the techies here figured out...

    small highway capable car, 100 mile range, $12,000

    Saw this and it looked interesting. I assumed it was a 3 wheel job, but it looks like a real 4 wheel small car. Not much technical specs at the web site though. i wish there were some of these locally where I could see what it was like to drive one. And be certain I could actually register...

    best way to wire in a booster battery pack

    I found a nice compact 11.1V 10AH lipo pack that I want to be able to add to the current battery on either of my e-bikes to increase the voltage. What is the correct way to wire these in? It comes with a two wire main power plug plus a 4 prong charger plug for a balancing charger. It would be...

    what do you think of this e-bike design

    http://ezridebikes.com/3.JPG http://ezridebikes.com/ I like the clean looks of this e-bike. Here is one solution to where to put the battery on a FS bike. How can you have wires coming out of a battery that spins though? Is there brush like contacts? Wonder how that will hold up. The...

    BMC hub, e-crazyman 48v 28amp controller?

    I was thinking of building another electric bike. I want a full suspension for riding the dirt trials and fire roads. I was thinking of actually doing a BMC geared hub motor on the front wheel this time, lithium battery on a rack behind the seat for a good front rear balance This way I could...

    Anyone selling the Puma hub motor in the US? Do they make the Puma in a rear wheel set up with a freewheel yet? Where can I find more info? I read the Puma is a step up from the BMC, is this true?

    best way to add 12 volts to a 48 volt 15AH LIFEPO4 to get 60

    I tested my KLH 20 inch wheel bike with BMC geared hub today at 60 volts, and I love it. I stuck a small LA battery in series to run the test, and was careful not to run it down too far. Top speed increased from 20 to 25 MPH, and hill climbing (which was awesome already) is now even better...

    have BMC hub & 48V 20a controller. will a 30 amp add much?

    Hello I am new to the boards here. I have a KLH 20 inch full suspension folder I run the EV tech BMC geared hub at 48 volts with a crystalite 20 amp controller. It climbs hill well and does a tad over 20 MPH. I wish it had a bit higher top end and even more torque. I run a Ping 48 V 15 AH...
