Electric Scooters

The Sparrow is a brushed motor boasting power and speed that surpasses systems on most ready-made electric bikes. Turn almost any bicycle into real electric transportation with the Sparrow system. This is the simplest system we make, using a brushed motor and a compact controller.

Sparrow front motors are available on 16 inch, 20 inch, 24 inch, and 26 inch wheels. Rear wheels are available by special order. Dropout width is 100mm for front wheels and 135mm for rear wheels. The axle is 9mm in diameter. Sparrow motors are 90 mm wide, extending 65 mm up the fork from the axle. Weight is 15.5 pounds laced to the rim.

This chart shows the performance of each system on the same bike on the same road with the same rider. The test begins at a complete stop, then full throttle is applied with no pedaling. Batteries UB12120, rider 140 lbs, level road, low wind, dry asphalt. The graph and the table below it show the speed (MPH) attained at intervals of one second from zero to the top speed. We believe this is more useful information than wattage since it shows actual power to the ground rather than power consumed. To calculate wattage, multiply volts times amps.

What comes with a Crystalyte kit from EVdeals?
Everything. And not in a million pieces, either. Your Crystalyte system will come from EVdeals already wired. You mount the wheel, throttle, cruise control (optional on some models), rack, and power bag, push together the connectors, and ride. The charger and rack are not shown in the photo, but are included.
