| Vehicle | 1994 Suzuki GSX-R 1100 This was a 94 GSX-R 1100 rolling chassis that I bought off of e-bay. These have a large and square main frame for motor and batteries. It arrived in about 1000 pieces- which Ive been slowly putting back together over the last 8 months. Inicdentally- GSX-R stands for Grand Sport eXperimtal - Racing. I replaced Racing with Electric...which made it sex-E. | ||
| Motor | D&D Motor Systems- Inc. ES-15-6 Series Wound DC Went back and forth - finally settled on this. Consensus seems to be that regen on a motorcycle is pretty useless...and these motors have more power than the equivalent sepex or PM. AC has a bit more power- but at more than twice the cost. | ||
| Drivetrain | Direct chain drive 5:1. 65 tooth rear- 13 front. | ||
| Controller | Alltrax 7245 Pretty standard. | ||
| Batteries | 24 other GBS- 3.60 Volt- Lithium Iron Phosphate GBS LiFePO4 from Elite power solutions. They rate the set up at 60 Ah- 87 V max- 76 nominal. Integrated BMS. The wider battery packs that bulge out near the front are suggestive of the inline-4 from the original GSX-R. | ||
| System Voltage | 76 Volts | ||
| Charger | Elite Power Solutions | ||
| Heater | Leather jacket. | ||
| DC/DC Converter | ??? This is the little 10A deal that Thunderstruck sells. It only has to power my headlight- LED tail and turns- and the gauge cluster (about 7A total). Its cheap and small. | ||
| Instrumentation | Trailtech Vapor | ||
| Top Speed | 70 MPH (112 KPH) ...at least- thats the plan. I have it geared to hit 70 at about 4700 RPM. The ES-15-6 is rated to 5500 RPM- so Im hoping this will hit 70 with room to spare...but well have to see. | ||
| Acceleration | Fast...I hope. | ||
| Range | I dunno. Others with similar setup say 30- 50 mi- so thats my guess. | ||

| Seating Capacity | 1 adult | ||
| Curb Weight | 375 Pounds (170 Kilograms) About 100 lb lighter than the original ICE GSX-R 1100. (Estimate based on weight of rolling chassis + specs for motor / controller / batteries) | ||
| Tires | Michelin | ||
| Conversion Time | So far- about 12 months...just finished the bike 1/15/2011. Still a few odds and ends- but it is together and running. | ||
| Conversion Cost | Ive pretty much lost track- but I estimate about $7000 invested. | ||
| Additional Features | Ive pretty much rebuilt this entire bike from the ground up. It came in about 1000 pieces- many of which didnt even match. I spent hundreds of $$ on new parts- paint- more parts- more paint... Custom headlight- taillights- turns- stripped everything down and repainted...fabricated the motor mount- headlight bracket- indicator lights- shaved the subframe and recovered the seat...after market lower fairing- mirror... Anyway...describing all the custom fabricated and machined parts is too much for here. Please check out my web-page. Ive done everything myself- either in my garage or in the machine shop where I work. | ||
| This thing has been a chameleon for the last 8 months. I havent been able to afford the motor and batteries until just recently- so I just keep changing things on the style side. Its actually given me a lot of time to work on the bike itself. Been a lot of fun tweaking the design- trying to get it just the way I want it. If Id had the money for the conversion right away- I would have just built it without all the custom work. I view building this bike as functional art. My inspiration comes from a mix of modern street-fighters- cafe-racers- and old school bobbers (emphasized by the flat-black with red wheels and brushed aluminum). And a little pimpin gold around the edges. I have to put in a shout out for the Jacob Smith who is building el-Gixxer. Thats how I decided to get a 93-95 era GSX-R chassis. Its like that frame was MADE to be converted to electric. Thanks Jacob (and Suzuki). | |||

| Web/Email | WebPage | ||||||
| Vehicle | 1978 Honda CB750 F2 Built by my fiance Lori and I with the help of a local machine shop- Ironman Fabrications time and space. A CraigsList.org donor invited me to drag this motorcycle out of his yard. It took three of us to get it onto a truck sideways and we left a streak where the rear tire had dug into his grass. The thing was rusted in a locked up position. | ||||||
| Motor | D&D Motor Systems- Inc. Separately Excited DC 13HP regen and reverse. Capable of ~300A. Id liken it to a 250cc bikes power- though when and how they make power are different. If I had gears like a Honda rebel itd be no contest. | ||||||
| Drivetrain | One speed- 420 chain. 12/60 gears. | ||||||
| Controller | Alltrax 4884 300A controller. | ||||||
| Batteries | 16 China HiPower HiPower LifePo4- 3.20 Volt- Lead-Acid- AGM The whole pack is 100AH at 48V. Do far ive gone 20 mile son it- so no clue on real range- though I suspect its over 60 mi in mixed driving. Update soon. | ||||||
| System Voltage | 48 Volts | ||||||
| Charger | unknown BC0 or BCO 16 cell balancer charger for Li 58.6v- 8Amp. Slick Little fellow works well. after first rides- the batteries are within 30mv of each other. | ||||||
| Heater | whatever Im wearing. | ||||||
| DC/DC Converter | nope. isolated circuit. Solar powered 5v USB circu LI rechargeable battery powered- and the back tail-light is a spooklight that has accelerometer controlled brake lights and turn signals that are wirelessly controlled by a remote on the handle bars. | ||||||
| Instrumentation | factory Honda Speedo. CellLog monitors on all cells. 48v cart gauge for overall pack at a glance is mounted to the tank. | ||||||
| Top Speed | 55 MPH (88 KPH) The top speed is around 55 mph so far. Only the Interstate and highways around NWA are over 40mph- so I have enough go-power to get a speeding ticket just about everywhere in my range. | ||||||
| Acceleration | confidence inspiring- and really quite good. 0-30 is faster than most cars are at the stoplights. 30-50 is smooth but slower. Im due to experiment with the gearing some. Itll do a burnout. | ||||||
| Range | 50 Miles (80 Kilometers) Will update with solid scientific information soon. | ||||||
| Watt Hours/Mile | tbd. instrumentation is lacking. Only have a battery meter. | ||||||

| ||||||
| Seating Capacity | 2ish. seats 2 but no rear sets for passenger feet. easy to add them back. | ||||||
| Curb Weight | 400 Pounds (181 Kilograms) this is an absolute guess- but it is lighter and better handling than before. | ||||||
| Tires | some on sale rubber from oldbikebarn.com front tire came with the e-bayed rim. | ||||||
| Conversion Time | Ive spent about 3 years doing this.Ive even moved houses in between. This is the bikes Revision 2.0 Anything I Know I did wrong the first time I have corrected but Im sure there is more to learn. | ||||||
| Conversion Cost | 3-4000$ from scratch. almost all of that is EV pats. TH lead acid version was half that. | ||||||
| Additional Features | The bike has had the rear brake deleted and shaved down the old brackets so now the regen motor does all rear braking. | ||||||

| System Voltage | 72 Volts | ||||
| Charger | Black & Decker 2/4/6 Amp x 6 I used 6 B&D 2/4/6 Amp chargers for bank charging. Eliminates the need for battery equalizers or BMS. Nice chargers for the money ($29ea). I would recommend stepping up to the 2/6/10 amp ones. 10 Amps would quicken the charge time without hurting the batteries. | ||||
| Heater | HA! I have been riding on 40 degree F mornings. BRRRRRR! | ||||
| DC/DC Converter | Kelly 72V - 12V 300 Watt Very nice DC-DC converter. Never a problem with lights dimming etc. One of the least expensive available. A little on the large side. Takes up a fair amount of space. | ||||

I since have upgraded the onboard charger to a Kelly 8 amp 72 Volt charger. | ||||
| So far I have 650 miles on it. I ride when ever possible. You may think the 75 AH batteries are too heavy- but I like the range- acceleration and the average speed I can maintain. I tried my best to make the bike look factory stock. I am enjoying this project and I am extremely happy with it. This was a huge learning curve. I made some errors in component selection- about $200 in money spent incorrectly. Could have been much worse! This bike is great fun and the torque and acceleration is a blast on the twisty back roads. I can enjoy riding with my wife to church or to the ice cream parlor and taking my son to the Scout meetings. No scooter can compare to the range and performance for the money. Things will only get better when LiFePo batteries become affordable. Advice: BUILD ONE NOW! dont wait until LiFePO batts are available. If you want to cruise at 50 MPH- size your components for 70MPH. I would suggest a 900 CC frame for a bike with more than 48 Volts. Do the research and call the suppliers of the products before you order. I have found that EVERY EV supplier has been willing to ensure you have the correct components rather than getting your money. Buy your donor bike from Craigs list in the middle of winter! Sell the ICE parts on E-bay! Before you buy the bike- search E-bay to see what the parts are selling for in the same condition. You should be able to calculate your potential return on your investment. Dont buy a bike that is in need of restoration. Buy a good quality running bike so after the conversion it will have maximum value and long life. THANKS TO ALL WHO POSTED THEIR PROJECTS HERE TO HELP ME DESIGN AND BUILD MINE!!!! 1200 miles and counting! | |||||

| Top Speed | 70 MPH (112 KPH) Calculations say ~70mph- however my baby ninja puts the same amount of HP on the table and it does 100- I think its going to depend on how much the SepEx control can compensate for the back emf and more importantly which sprocket I decide to keep (5:1 or 7:2) so well see... |

| Vehicle | 1974 Yamaha TA-125 This was a Formula IV road-race bike with a 2-cylinder 2-stroke engine- putting out 29-hp with Vesco pipes. It weighed 180 lb dry and topped out at about 130mph (at 13-000 rpm). In 1976- when the reed-valve engines came in- I parked this bike at the back of the garage. In 2008- I disinterred it- dropped the engine and bolted in a golf cart motor running 48 v. With small SLA batteries it weighs 210 lb. | ||
| Motor | D&D Motor Systems- Inc. ES 71A 52 Separately Excited DC Mike Dieroff at D&D was very helpful -- responded promptly to my email- took my phone call and specified a motor that turned out to fit perfectly. No cutting or welding required: I just made a couple of aluminum cradle arms. | ||

| Top Speed | 60 MPH (96 KPH) Not registered so Im riding it as if it were a moped -- 30 mph limit. In theory its geared for 60 and Ive gone that fast downhill. Going downhill the bike itself should be stable and safe beyond 90 mph but the motor is supposed to have a 4500 rpm limit. The bike is fun as hell. | ||
| Acceleration | Brisk to 35 mph. | ||
| Range | 12 Miles (19 Kilometers) Havent pushed it beyond 4.5 miles yet -- the distance to the office. | ||
| Watt Hours/Mile | 80 Wh/Mile City streets- traffic lights- stop signs- mild hills- SUVs. | ||

| Seating Capacity | 1 immature adult | ||
| Curb Weight | 210 Pounds (95 Kilograms) | ||
| Tires | Dunlop 80/90 H18 -- ancient road racing tyres | ||
| Conversion Time | 20 hours | ||
| Conversion Cost | $1200 | ||
| Additional Features | Plastic Magura twist-grip pot. Original massive drum brakes aid regenerative braking. Original racing-crouch riding position with clip-on bars and rear-set pegs. With no clutch or shifter- theres not much for three limbs to do. Bicycle LED head and tail lights. Bike is still sprung for 90+ mph so its a little harsh on pavement seams. Steering lock is limited so care must be taken maneuvering in parking lots. | ||
| Mar. 5: Back in operation for the spring. Batteries are good for only about four miles if air temp is below 40 degrees F. LiFe batteries may fix this. Dec 10: Parked for the winter- with the charger on a timer so it gets a little juice each night. Nov 24: Running reliably. I can ride it to work whenever the morning temp is over 38 degrees Fahrenheit and the pavement dry. Side panels are in place so the bike looks pretty nice- finally. Nov 12: Hard freeze last night and it wasnt kind to the batteries. I barely made it to work. I may have to bring the bike indoors at night -- my garage is unheated. Nov 6: The bike is running just fine. A short across the throttle switch kept the controller from booting- and it took a few days to diagnose. Controller now boots instantly. Clocks have changed and Im coming home in the dark- but Ill commute as long as the streets are dry. Meanwhile- as long as I had the wiring apart- I cut a hole in the bottom of the tank to provide clearance for the controller and a place to hide some of the cables. Looks a lot cleaner now. Sept 30: Rewired to get all the bits under cover. Its a tight fit. Acquired a gold-plated fuse holder for the 250-amp ANN fuse and found room for it on top of the battery stack. Sept 23: Want an original dolphin fairing to hide the mechanicals- and I also need to weatherproof (that is- hide) the snake nest of wiring. Sept 20: Commencing daily commute- amongst the migrating SUVs. Feel like a gazelle amongst elephants. Controller sometimes takes awhile to boot -- something is sporadic in there. Sept 19: Were up and running. Development process viewable here: WebPage | |||
