too strong for a bike is it possible?

wanted to ask what does everyone think about this.I bought a 24 speed bike in 07 which ran great until I replaced the chain. after that it was all problems with the drive system. I replaced the cassette because the new chain slipped over the old gears. The man at the bike shop said that the chainring looked good and shouldn't have needed to be replaced but said that I had become too strong for a geared bike and I had too much torque which was causing the chainring to throw the chainI am tall 6.4 and have legs that have a lot of natural leverage on a bike as well as being strong and so because of this I now ride singlespeeds because of the closer chain contact as well as the bigger chain and tooth profile of the gears. No ramps and all.This happened the most in 32/18 or so.but this happened on new geared bikes I tried for a time as well.Basically I think it was like it was like putting a motorcycle engine on a machine designed for human powerSo my question is can any human actually exceed the limits of a bike?. have enough power to cause failure or malfunctioning of the parts?. Throwing or breaking chains, bending crankarms, chainring etc.I know that track bike sprinters with those frighteningly huge legs can put out upto 2 hp and go up to speeds of over 40 mph and they ride single speeds mostly, probably because of how they would tear down a geared bike with even a moderate touch of power.While I might not have that power as those guys I probably could say that when I was 17 back then and at my peak that I could have had at least 1 hp since I in fact had beaten a small engine bike when I still rode the 24 speed.could I really have a touch of superman in my legs??
