RoadRunner motors are brushless, meaning the energy is transferred to the motor in a more sophisticated and efficient way. RoadRunner motors have no brushes to wear out, but brushes last a long time. The main advantage that the brushless motor is more efficient, meaning you get more miles per charge. RoadRunner front motors are available on 16 inch, 20
inch, 24 inch and 26 inch wheels. Rear 7-speed and 8-speed wheels are
available by special order. Dropout width is 100mm for front wheels and
135mm for rear wheels. The axle is 9mm in diameter. RoadRunner motors are 75
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. Note: We are surprised at the results of the 3620 and will re-take the test when time permits. This is a very nice system and we believe it should be able to attain 20 MPH.
Range (distance per charge) depends on many factors including tire tread pattern, tire pressure, weight of rider, wind, hills, stop-and-go, rider driving habits. We expect 10-14 miles from the RoadRunner using 10AH batteries, no pedaling, regular city traffic, running as hard and fast as we can. Adding pedal power helps, particularly at start-up. An experienced rider willing to do some pedaling and keeping speed under 20 MPH may get more than 20 miles on a charge. As with a car, the faster you take-off and the faster you run, the more fuel per mile you will use. |

| 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. |
