Vehicle2007 Harley imitation
To my knowledge this is the first Slovenian electric cruiser
MotorISKRA AMJ Series Wound DC
Very aggressive, 8000 revs. We had to gear down the revs drastically to around 400 rpm. Half of the revs taken off by a belt drive and then the chain drive (no room for another belt) for the rest of the 20:1 ratio needed
Drivetrainchain AND belt
ControllerKelly KDS48200E
Fits the motor like a glove.
Batteries4 CTL 26Ah/12V by CTM, Germany, 12.00 Volt, Lead-Acid, AGM
When one builds an EV, one must ask this: do I really need 2000 euros worth of Lithium batteries if I want to go 10 miles to work and back? This bike could have any kind of batteries, but for my needs, this was sufficient.
System Voltage48 Volts
Charger No-name for 15euros from supermarket
It's small, 4A, but it gets the batteries filled overnight.
I plan to buy an industrial-sized charger to have it at home and carry the small one with the bike, inside the gas tank. But for now a small cheap charger is efficient enough.
HeaterWhen so many people look at you in disbelief and admiration, your heart warms up :)
InstrumentationBurned rev counter, accidentally, with 48V instead of 12V bwahahaha... Had to destroy something :)
The gas meter on the former gas tank now shows main voltage 48-52 Volts.
Top Speed35 MPH (56 KPH)
It goes 55 km/h with such ease that I think it could go up to 75 km/h, 47 mph.
AccelerationStart from 0: scary. Afraid of breaking the chain or the belt drive. Must start slowly. Up to 30 km/h excellent. Up to 50 km/h easy.
Range30 Miles (48 Kilometers)
Batteries that I used for mockup and to experiment with were old when I got them 2 years ago. it hardly moves me to town and back. I just got new batteries, 50Ah, expect something like 30 miles out of them. Will report soon about that...
EV Miles
Current:140 Miles (225 Kilometers)
Seating Capacity2 adults
Curb Weight320 Pounds (145 Kilograms)
Less than the original petrol bike.
Conversion Time2 years of development, but now that I know what to do and how to do it, I believe it can be done in 16 man hours.
Conversion CostApprox. 3200 euros at least (2800 without batteries).
Got ripped off by a Slovenian electric motor maker, Magnel, lost 1100 euros. They sold me an inadequate motor and controller, I returned it but when they were supposed to return the money, they shut down all communication. Slovenian justice system favours the bad guys by working so slow that people give up or cases go cold. Extremely dissapointed. Stay away from Magnel.
Additional FeaturesWe kept the modifications to minimum to lower the costs and kept the bike stock. Every biker wants to modify and accessorise his bike to his own wishes.

I converted the motorcycle to a 28 mph/45kmh "moped" cathegory so that everyone can ride it even without a motorcycle permit.
The benefit of keeping it slow is that it consumes less power -> needs less batteries -> saves weight -> needs even less power.
This is only a prototype, made and paid by a poor journalist and his 'electric' friends. But it has potential... I almost went bankrupt to develop this beast but I'm proud of it. It's sexy, it's cheap, it's environmentally friendly, it turns heads, what else do you need :)

Open for business, tell me your wishes :)
