| Vehicle | 2000 Kawasaki EX250 Ninja | ||||||
| Motor | Advanced DC K91-4003 Series Wound DC | ||||||
| Drivetrain | Chain | ||||||
| Controller | Curtis 1209B-6402 Mounted under the forward edge of the seat on a 1/4" aluminum plate heatsink. It never gets warm to the touch. The heat sink and controller must be electrically isolated from the chassis! | ||||||
| Batteries | 6 Valence U1-12XP, 13.30 Volt, Lithium-Ion 40 Ah . . . PakTrakr reads 13.3 volts each after a full charge. The people at Valence were very helpful. I'm very happy with my batteries so far. Lately I've started experimenting with Thundersky LFP090s. The Battery frame/holder was made from 1/4" aluminium sprayed with truck bed liner. | ||||||
| System Voltage | 80 Volts | ||||||
| Charger | Zivan NG1 I use the Zivan charger to do the bulk of the charging. If my pack ever gets out of balance I use my little Schauer 12 amp charger to bring up the lowest battery. The Schauer JC1212 charger's 14.6 volt 12 Amp output is perfect for topping off the lithium batteries. I just hook it up and walk away. I don't have to worry about over-charging. | ||||||
| DC/DC Converter | Sevcon 622/11086 72/80 volt input 300 Watt 13.5 Volt output Mounted under the seat. | ||||||
| Instrumentation | PakTrakr 600EV with hall effect current sensor. | ||||||
| Top Speed | 70 MPH (112 KPH) The front sprocket is currently a 16 tooth from www.grainger.com. I have a 72 tooth #420 sprocket from www.sprocketspecialists.com on the rear. | ||||||
| Acceleration | Big EV grin! I currently have my Curtis controller acceleration rate and current limit turned all the way down and I am still very happy with the acceleration. Nobody honkin' at me! | ||||||
| Range | 30 Miles (48 Kilometers) 30 mile range at 55 MPH. I commute to work 22 miles each way with several hills and sometimes high winds. The average speed of my commute is about 55 to 60 MPH. Beware of electric scooter manufactures who claim a 65 mile range. YEAH ... WHATEVER ... IF your only going 25 MPH! | ||||||

| Seating Capacity | 2 adults | ||||||
| Curb Weight | 0 The ICE bike weighed 305 lbs. dry | ||||||
| Conversion Time | About 6 good weekends. But the modifications are on-going. | ||||||
| Conversion Cost | About $7,000.00 . . . mistakes included. In April '08 I qualified for the clean air tax credit. $2500.00 bucks right off the top of of my 2007 Utah state taxes! YAHOO! I will get another $1250 off of my 2008 Utah State Taxes! I sold my old gas engine for $80.00. I've got a little 100cc scooter that I use when I'm doing mods to the Ninja. People tell me there is no way I will ever recover all of the conversion costs with gas savings because I will eventually have to buy new batteries and that I could have just rode my scooter and saved more money. I say, "so what, that's not the point". Then I ask "So when will your Mercedes start to pay for itself? Instead of buying & driving a Mercedes you could have bought a forty dollar bus pass each month and saved more money!" I glide to work everyday, almost silently through the trees on the outskirts of Salt Lake City. It's a joy to ride. I really look forward to my commute. Was it was worth all the money. Hell yeah! At least a little bit less of my hard earned cash is going to the oily bastards. | ||||||
| I would recommend the Kawasaki EX250 when doing a conversion, because they are lighter than a lot of other bikes you could use and you can get parts ANYWHERE! | |||||||
