Review on Aluminum Wheels 66Cc Motorized Bicycle by Mark Walsh

According to the description, the impeller was specially developed for motorized bicycles. The only thing I can say that makes this true is that they are round. I had less than 20 miles on them by the time I cleanly loosened all 6 bolts holding my rotor and sprocket to the rim on my second day of riding. This causes the rotor to bind and bend, causing the hydraulic caliper to brake. Also sends me through the bars in traffic at 30+ miles per hour. I recommend the best quality wheel with at least 36 x 12g spokes in a double wall steel wheel. Even with a regular Chinese engine. I will never use a magnesium wheel on a motorized bike ever again. Especially these wheels. Absolute rubbish and waste of money. Do not use these wheels on a motorized bicycle if you care about your life.
