"RADICAL PEDAL MOTOR makes my bike sound like a real racing machine!  The faster I pedal, the faster the sound goes and the louder it gets.  It is WAY cool." -Allen

"I heard of RPM-Bike out of the Boys Life magazine. My brother is a boy scout and I was just looking at the ads. So the plates don't make the bike go faster they just make the sound of an engine?"  -Grant

"This thing lasts FOREVER!  It was so easy to put on my bike too.  Just a few zip ties and making sure to get the motor tongue positioned right and it worked great!  I was even able to make up the number I wanted!!"  -Zack

"My brother and I race with each other with our Radical Pedal Motors.  I have a red RPM and he has blue RPM.  I pretend to be Dale Earnhardt Jr. and he pretends to be Ryan Newman.  Even though he beats me most of the time, my bike and RPM sounds better than his does because my bike has smaller wheels. So the harder I pedal the faster it sounds than his because of the wheel size difference!  We love our Radical Pedal Motors!" -Broderick

"I've never in my life seen anything like this at all.  My Dad says he used to use baseball trading cards and clothes pins when he was a kid to do the same thing, but he said his didn't last very long at all.  Man, this one won't quit!  He said he wished he had one of these as a kid.  It's cheap too!"  -Johnny
