Look to the right side bar, and you’ll see the new “EV Safety” Page. I have had my fair share of stupid accidents, and now want to prevent anyone else from making the same mistakes. I have included many pictures and helpful tricks to improve electric vehicle safety.

Thanks for looking!

Electric Motorcycle Torque!

Filed under: Uncategorized — tonyhelms @ 12:04 am

I filmed this the other day after I realized with the new 72 volt performance the motorcycle could lift the front wheel off the ground. The torque output of the Mars “RT” motor is astonishing, and sometimes dangerous when on slippery or loose surfaces.

Thanks for watching!

TTXGP Standings After a Dogfight at Infineon Raceway

Filed under: Uncategorized — tonyhelms @ 10:31 pm

Although I could not attend the first 2010 TTXGP race in California I am very proud of my friends out there giving it their all to prove that electric power can dominate a racetrack just like gasoline fueled motorcycles. Each team was rushed to finish their machines in time to attend this race, For the TTXGP race, 11 bikes showed up, 10 bikes made it onto the track, and 8 bikes finished the race with one of those being pushed across the finish line by the rider. The determination and passion from these teams will inevitably bring us new and improved technology to our every day electric vehicles.

Video of lap one, the first 2 bikes are team Zero/Agni, and team Lightning

The standings for the 2010 Infineon race are as follows,

1. Shawn Higbee (Zero/Agni), 11 laps, 25:33.626
2. Michael Barnes (Lightning Motorcycles), -1 lap
3. Michael Hannas (Electric Race Bikes), -1 lap, 12.456 seconds
4. Jennifer Bromme (Werkstatt Racing), -1 lap
5. Kenyon Kluge (KSquared Racing), -1 lap
6. Zoe Rem (Pril Motors), -2 laps
7. John Wild (Square Wave), -3 laps
8. Jason Lauritzen (ElectricMotorsport.com), -3 laps
9. Spencer Smith (Volt Motors), -2 laps, DNF, crash
10. Thad Wolff (Team Electra), -8 laps, DNF, mechanical

I am very happy to see growing interest and respect in electric power with the TTXGP proving that electric power can be equal if not better then gasoline powered vehicles.

Perm Motor failure, E*speed down for re-enginnering

Filed under: Uncategorized — tonyhelms @ 12:07 am

Unfortunately I was in the process of making a sweet video for the E*speed when I had a catastrophic motor failure at a very high speed.

–58 miles on the E*speed so far

while testing high speed endurance I was peaking at around 96 mph and all the sudden I hear loud pops and what sounds like lightning behiend my leg, I peek my head over to see the motor literally on fire! I smack the main contactor switch and kill all power to the bike and gently coast to a stop.

–smoke damage is visible

I used my infrared thermometer and read a motor temperature of 478 degrees F. The copper inside the motor was molten and thrown all round the swing arm.

–molten copper thrown from motor

I knew the specs of the perm motor was 110 amps continuous and 200 amps for 10 minutes. I was watching my “cycle analyst” which reads real time amp’s and records the max amperage draw. So I look at the max amp, and its only at 156 amps, so what gives why did my motor blow?

I didnt know this until just recently, the speed controller made by Alltrax bumps the amperage up by almost 2 times. My shunt was installed in the input battery side, not the output motor side, therefore I was limited by what the gauge was reading out to me. Unaware to me I seriously overpowered the motor and burned it to pieces, quite literally!

–motor brushes removed, the center insulation is melted

as they say, hind sight is 20/20

Although this was a very expensive mistake, It could have been much worse and caused an accident, or burned the entire bike down. I believe I will be switching the drive system to AC now, which will require much modification of the motorcycle.

Gotta love experimental projects!

Plymouth Green Street Fair

Filed under: Uncategorized — tonyhelms @ 11:00 pm

Once again the MEAA (Michigan electric auto association) met up on a sunny and warm Saturday out in Plymouth Michigan to show off our electric vehicles at the “Plymouth green street fair”.

With many downtown streets closed off and almost one hundred booth’s to visit, the fair was very well attended. There was a little of everything there, ice carving, ethnic foods, recycled furniture, and electric transportation.

Will Smith and Larry Tuttle pictured here in front of the MEAA booth. Larry is the proud owner of a very nice electric s-10, and Will is the owner of the electric silver Volvo.

Pictured here is Pete Deptula’s Hybrid escort and my E*speed motorcycle.

The two production companies there were GM and Smart, GM had one of there many hydrogen fuel-cell equinox on display. GM had some serious engineering and funding wrapped up in these, although with all the advances in hydrogen the most asked question was where the hydrogen is available. Unfortunately GM fell short with an answer. And even if there were hydrogen fuel stations it takes about 3 times the amount of energy to produce, transport, and store hydrogen,(with current technology) then to completely charge most electric cars, and power outlets are already installed in every home, business, and gas station. For more Hydrogen information visit my link on the right column.

GM was also showing off there super complicated 4L60E hybrid transmission. The two drive motors are inside the transmission along with planetary gears, clutches and fluid. There’s something to say about how simple the 100% electric drive trains are compared to hybrid drive trains . Take a look at Tesla’s drive train, it is composed of 1 gear reduction and a differential with about a dozen total moving parts. There’s a certain elegance in simplicity.

Smart car was there displaying one very sharp cabriolet, although the MPG may fall slightly short of what most people expect, it is much better then most cars. The engineering and finish work is top notch, even if you are very tall you will have no problem fitting in the smart car. If all you plan to do in the car is go too and from work the smart car is a great answer, low maintenance, and easy parking are two nice features of the car.

I had the pleasure of meeting Jeremy Panizzoli, the founder and president of “Eco Wheelz” a company that custom builds, and sells production electric bicycles. He is located in downtown Plymouth about a block from the fair. I saw several of his bikes driving around the streets during the day. Unfortunately I got held up and did not get to his shop in time, it was already closed. But I look forward to seeing him at the future EV events around the state.

I have added a link to his web site on the right column of my site.

Thanks to everyone who came out to see us at the show, if you enjoyed what you seen come and join us at the Livonia EV rally, it will be held on Saturday June 12th at School craft college in the parking lot.
