|Location||Imperial, California US map|
|Vehicle||Harley Davidson Harley / Buell style parts used |
Building a Harley style motorcycle with the usual parts, but with a custom frame to hold the motor and batteries. Some Buell parts.
|Motor||Advanced DC BQ5-4001B Series Wound DC|
24 volt, 6.7 inch, no fan. Very heavy. An Etek, PMG132 or LM202 would help keep the weight down.
|Drivetrain||Harley / Buell style chain drive. Tapered hub splined to match motor shaft.|
24 to 36 volt, 275 amps.
|Batteries||2 Optima Blue top, 12.00 Volt, Lead-Acid, AGM|
|System Voltage||24 Volts|
A 1.5 Amp automatic charger will be attached to each Optima battery used.
|Heater||Helmet, gloves, boots.... We do not get too cold here in Southern California.|
|DC/DC Converter|| |
Use individual traction batteries for auxiliary uses. Spread out the load evenly. Be very careful about grounding issues.
|Instrumentation||I hope to install a voltage meter, speedometer / odometer.|
|Top Speed||I was hoping to achieve 40 mph, but the 3.3 mile route to work was just increased to 50 mph. Alternate route to work of 4.3 miles at 40 mph max.|
|Acceleration||Assumed to be very slow at first due to weight of motor and Optima batteries.|
|Range||Would like 10 miles. It is 4.3 miles to work by slow surface streets.|
|Seating Capacity||One to two.|
|Tires||Rear rim 18 X 8.5 inch 80 spoke chrome with a 240/40R18 Metzeler tire to support a wide frame to "hide" or match in with the large batteries and large motor. Rear tire is 9.5 inches wide, 25 inches tall, 79 inches circumference. Front rim and tire not yet purchased.|
|Conversion Time||In process. Gathering parts for a while now, began assembly on 2/6/2007.|
|I am curious about top speed. I would have liked to go with an Etek style motor for less weight and higher output, with four optima batteries. The Advanced DC motor is heavy. I will first try only two batteries to try to keep the weight down, while building a frame that can accept four batteries if needed. If speed / range are a problem, I can run the 24v motor at 36v. Because of the weight, friction, rolling resistance, wind resistance, etc. I think the maximum speed and acceleration will be poor. I am guessing 2300 rpm, front pulley 12 teeth, rear pulley 48 teeth, rear wheel rpm 575 , rear wheel circumference 79 inches, 45,425 inches/minute, X 1ft/12inch X 60 minutes/1 hour X 1 mile / 5280 ft = 43 miles per hour.|
