But he's not the only one converting old bikes! Russ Gries is a fellow DIYer, and his electric motorcycle is centered around parts from an old battery-powered forklift. He got it for free from the company he works for, and after acquiring the carcass of a 1976 Honda CB550 for $50, he got to work. After about 120 hours and a net cost of $15.61 (that's right, he got money for recycling the rest of the forklift), the result is Voltzilla. See below for specifications, photos, and videos, including the first ride.
Specifications of this DIY Electric Motorcycle
It's a bit different from most electric conversion, in good part because of its forklift ancestry:

• It is running on 24 volts. Most others are 48 volts and up.
• "the transmission was retained, because Gries wanted the flexibility of variable gearing for the hills where he lives (most other converted bikes are direct drive from the motor to the rear sprocket)"
• It has a reverse, just like the forklift
• The four batteries are from golf carts. They are used 6 volt 220 amp models. Most other conversions use smaller batteries with less capacity
• Current top speed is around 35 mph (56 kph), but after a drive pulley swap, he should be able to get 60-65 mph (100 kph)

Because of the heavy batteries, Voltzilla weights about 740 lbs, but its center of gravity is very low and it is well-balanced, so it's not a problem.


Not Finished yet: What Still Needs to be Done

• Rebuild the front brake
• Fix the speedometer
• DC/DC converter to run the 12 volt systems from the 24 volt batteries
• Panels to cover the electronics
• Disassemble, clean, paint, and reassemble

Ultimate Goal for this Electric Motorcycle & First Test Ride
Gries wants to use it to commute to work, a 24 miles (38 kilometers) round-trip

I want to build an electric bike... Not cause I love the environment, but just because it'd b coolio.

Oh and nice gear squiddles mcsquidly...

Yeah it'd be cool, electric drag bikes are already in the 7's. It just doesn't...sound right...

Killacycle Battery powered drag bike NEW ELECTRIC VEHICLE WORLD RECORD 7.82 @ 168 MPH

Now running 1210 A123 M1 Nanophosphate Li-Ion battery cells that produce 500 hp (up from the previous record set with 990 A123 M1 cells and 350 hp)

that thing sounded like a whip take'n off... CRACK!

[OneSickPsycho]

FYI - 500HP = 373,000 watts... That's some SERIOUS shit.

cool. but im a big fan of petrol. FFS im the last generation thats gonna be using the shit might as well make a party of it.
