ZAPWORLD.COM Drive System - DX Specifications:
Weight: Battery weight: 13 lbs. Motor weight: 8 lbs. Charger weight: 3 lbs.
Motor: dual, high efficiency, ceramic, permanent magnet direct current motors. They have a 400 watt (1/2 horsepower) combined peak output (200 each). Without a load they rotate at approximately 5,000 rpm. Adapted from an automobile radiator fan motor; sealed and capable of operating under water. [ZAPWORLD.COM's systems are rated in-house, using a small motor dynamometer. The rated power is chosen as the power output at the shaft at the most commonly operated RPM (3000 rpm). The peak rating is the greatest power the motor is capable of putting out, which is 200 Watts each (746 watts = 1 horsepower). Average people expend 100-150 watts of energy riding a bike which is sustainable for an hour or so; 300 watts for minutes at a time. Average output of Chris Boardman during world-record 35.03 miles in one hour: 450 watts. Power consumption of a typical two-slice toaster: 1,000 watts.]
Regenerative Function: The motors can help recharge the battery on descents, when engaged during pedaling, or when used on the charging/exercise stand. Up to forty amps can be generated.
Drive Roller: Unique torque sensing mount adjusts automatically for maximum traction and efficiency. The roller, made of a ceramic composite for long life and superior gripping, works well even when wet. (Historical note: Known as the "stone roller", this 4th generation roller follows 1) a sandpaper-looking roller, 2) a cross-hatched steel alloy roller, and 3) a grooved steel alloy roller.)
Controls: Two speed, solid state/electro-mechanical system with regenerative function. Spring loaded safety on/off trigger switch shuts off motor when released.
Battery: Sealed, maintenance-free, lead-acid twelve volt, 20 amp-hour battery is approximately 7" x 7" x 3" and weighs about 12.5 pounds. Not a motorcycle battery, but rather a deep cycle battery used for computer Uninterruptable Power Supplies (UPS) and medical technology (X-ray machines). Battery type is starved electrolytes dry cell. Maintenance Free, Lead-Calcium Grid, Usable and rechargeable in any position. High discharge rate capacity. Deep discharge recovery. No memory effect. Purported to be a PANASONIC LC-RC1217p. Although, someone who should know says: "Actually, any sealed lead acid battery with a 17ah-20ah rating (12V) will be the correct dimensions and configuration. There are tons of them out there." Commonly available.
Battery Containment: Battery bag is a heavy duty nylon cordura material with wide Velcro-lines flaps that hold the battery to the battery tray; a 1-inch polypropylene strap completes the connection. When the flaps are opened, polypropylene handles allow for quick and easy removal and carrying.
Speeds: Non-pedal speeds on level, smooth roads are approximately 10 and 18 mph (180 pound rider). If you pedal, you can go faster. Lighter riders may go faster; heavier may go slower. The motors are powered in series to achieve 10 mph and in parallel to get 18 mph.
Range: Total range is dependent on terrain and rider input through pedaling. The standard battery is good for up to one hour of riding (typically 8-20 miles). Generally, you can count on 10 miles in the fast speed.
Recommended Tires: 26" x 1.5" semi-slick tread width.
Charger (aka Quick Charger): Automatic, portable, six amp, quick charger plugs into standard electrical socket (110 VAC). Charges in three hours or less. (Charger output is 6 amps. Charging for 3 hours produces 18 amp-hours, nearly enough to fully charge a totally drained 20 amp-hour battery.) Costs about 5 cents per charge. (Charger uses 1.3 amps at 120VAC or 156 watts. Three hours of charging uses 468 watt-hours or 0.468 Kwh. At a cost of $0.11/Kwh, that's about 5¢ per charge or 0.3¢ per mile.)
Here's a user's suggestion: "ZAP owners save some money if your ZAP charger fails. Go to your local NAPA auto parts dealer and order the NAPA charger #85-315 (made by Exide). This is the same charger ZAP sells for 30.00 less. You will have to crimp your charging ends though. It comes with alligator ends. Also, NAPA will give you a two year warranty, ZAP will give you one."
Hardware: alloy mounting brackets.
Warranty: One year limited warranty.

ZAP Power System - SX Specifications:
Weight: Battery weight: 13 lbs. Motor weight: 5 lbs. Charger weight: 3 lbs.
Motor: single, high efficiency, ceramic, permanent magnet direct current motor. Motor has a 290 watt (1/3 horsepower) output. Without a load, rotation is approximately 4,000 rpm. Adapted from an auto radiator fan motor; sealed and capable of operating under water. ZAPWORLD.COM's systems are rated in-house, using a small motor dynamometer. The rated power is chosen as the power output at the shaft at the most commonly operated RPM (3000 rpm). The peak rating is the greatest power the motor is capable of putting out, which is 290 Watts (746 watts = 1 horsepower). Average people expend 100-150 watts of energy riding a bike which is sustainable for an hour or so; 300 watts for minutes at a time. The athlete who pedaled and flew "Gossamer Condor", the human-powered airplane, could deliver around 1/3 horsepower. Pedaling alone at about 12-13 mph uses as much power as walking a 15 minute mile - about 1/4 hp. That's typical of the average recreational cyclist.
Drive Roller: Unique torque sensing mount adjusts automatically for maximum traction and efficiency. The roller, made of a ceramic composite for long life and superior gripping, works well even when wet.
Controls: One speed, solid state/electro-mechanical system. Spring loaded safety on/off trigger switch shuts off motor when released.
Battery: Sealed, maintenance-free, lead-acid twelve volt, 20 amp-hour battery is approximately 7" x 7" x 3" and weighs about 12.5 pounds. Not a motorcycle battery, but rather a deep cycle battery used for computer Uninterruptable Power Supplies (UPS) and medical technology (X-ray machines). Battery type is starved electrolytes dry cell. Maintenance Free, Lead-Calcium Grid, Usable and rechargeable in any position. High discharge rate capacity. Deep discharge recovery. No memory effect.

ZAPWORLD.COM manufactures the Zappy electric scooter using a single, 12 volt ceramic, permanent magnet DC motor used in automobiles to turn the radiator fan. These electric motors are sealed and, therefore, can be operated under water for short periods. ZAPWORLD.COM's systems are rated in-house, using a small motor dynamometer. The rated power (150 Watts continuous) is chosen as the power output at the shaft at the most commonly operated RPM (3000 rpm). The peak rating is the greatest power the motor is capable of putting out, which is 290 Watts (746 watts = 1 horsepower, so 150 watts = 0.2 hp). Average people expend 100-150 watts of energy riding a bike which is sustainable for an hour or so; 300 watts for minutes at a time. The athlete who pedaled and flew "Gossamer Condor", the human-powered airplane, could deliver around 1/3 horsepower.
Here's your basic Zappy rolling along under water. "The reason all these puddle stories have such good endings is, the electronics in the ZAPPY are waterproofed (it's a clear-coat) here at the factory. We don't recommend submersion (eventually a short will happen), but odds are that your ZAPPY will work fine after just about any water encounter."
TORQUE:
Continuous: 75 oz-in @ 3000 RPMs, (4.69 lb-in, 0.39 lb-ft, 0.53 Newton-Meters) (0.22 hp) Design Torque = 9.4 lb-in
Max: 225 oz-in @ 1750 RPMs, (14.06 lb-in, 1.17 lb-ft, 1.60 Newton-Meters) ) (0.39 hp) Design Torque = 28 lb-in
Stall: 440 oz-in (27.5 lb-in, 2.29 lb-ft, 3.12 Newton-Meters) Design Torque = 55 lb-inThe throttle switch is a two-pole momentary switch that must be held in the ON position for the motor to work. It's spring-loaded to OFF. The switch is connected to a controller which senses the electric field generated by the moving motor. When the rider pushes the scooter, the controller enables the throttle switch. This feature prevents overloading the motor when starting. The "transmission" is simply a toothed belt between the small drive roller and large one on the wheel.
Zappy batteries are the same as DX and SX batteries. (See "ZAP Power System - DX Specifications" above.) Commonly available.
A 1.5 amp, 12-volt battery charger is provided with each scooter. The charger's 6-inch cord plugs into a household outlet; the charger's 4-foot cord plugs into the ZAP battery using a quick-connector (Motorola-type). Recharge the battery promptly after each ride. The charger won't overcharge no matter how long it is plugged in. Charging generally takes less than ten hours (maximum = 13 hours).
The Zappy toothed drive belt (Gilmer belt) is 1/2" (or 9/16")" x 21" and manufactured by Gates Rubber Co., 990 S. Broadway, P. O. Box 5887, Denver, CO 80217, 800/759-0921, model: PowerGrip HTD, #535 5M 15 (or 8GMC) Product # 9293-0538 (535 mm long, 5mm tooth pitch, 15 mm wide) (107 teeth, 21.06 inches, .08 lbs)).

I just bought 4 batteries for my scooters for almost 50 - 70% LESS than most of the companies charge. I paid only $19 for the 12V 7AH, $37 for the 12V 12AH and $39 for the 12V 17AH. The shipping is very reasonable too. I've already been using the batteries for almost 3 weeks now and it runs as good as the one I bought from another place that cost more than twice as much. The company's website is:
http://www.aventrade.com/Batteries with the same connectors and size as the ZAP:
PowerSonic PS12180 NB http://power-sonic.com/ for dimensions and Specs
Panasonic LC-RD1217P
http://www.agtbattery.com/Lead_acid.htm
The LA12180 looks close to the ZAP Battery for $46.
http://www.agtbattery.com/John Wayland recommends these Battery Manufacturers, but they don't have exactly equivalent batteries:
Hawker Energy Products Inc. http://www.hepi.com/
Acceptable batteries might be the Trolling Thunder 650, odyssey PC 680, or Genesis G16EP Part 0769-2007. I'm not sure about the connectors and the sizes are close to the Zappy but not exact.
"The 16EP Steffan listed is for all intents and purposes, an exact replacement battery that will snugly fit into the Zappy battery compartment exactly as does the stock Zappy battery...Specifically, the Genesis model 12v16Ah10EP is an AGM battery with the same dimensions, pretty much the same weight, at the C/20 rate the same or even better ahr capactity (it's conservatively rated at 16 ahr, C/10), and it has more robust terminals that will accept the same ring terminals that are attached to the stock ZAP twin wire battery power lead harness. As I stated before, this the same battery I use in my electric drag car for motive power, and it is tough as nails. The short circuit current rating for this stout battery is an astonishing 1600 amps!" John WaylandOptima, http://www.optimabatteries.com./main.htm . It doesn't look like they have any off-the-shelf products to replace the ZAP battery.
