Cranbrook bikes have their flaws and quirks like any department store bike nowadays, but weak axles aint on the list. 6'4, 220? Buddy, I'm 6'2 and almost 3 bills. Never had an axle break on me. And I've been using a cranbrook wheel on my custom bike since I built it almost 4 months ago. It's now got a Shimano coaster brake assembly, but that's only been added recently. If Huffy axles were known to fail, I might consider that your size has something to do with it. But they aren't, not even on motorized Huffy's. My personal opinion, either you got the one bad axle in a million, or you did something wrong and that caused the axle to break. If you removed the brake shoes, that would cause the axle to bend and possibly break. Any sort of improper hub assembly could also cause an axle failure. And there is nothing wrong with being a new builder and making a mistake. We've all been there, it happens. I'm on my 3rd bike (first custom) and even though I tried very hard, I did not built it 100% right from the start. I made a few mistakes. My most recent mistake was improperly repairing my carburetor petcock, which caused a gas flow issue and stalling/fuel starvation which caused me to miss work today. A rookie mistake, and I've been working with motorized bikes for 4 years now. The important thing is to know the difference between defective parts and user mistakes, so that you learn from your mistakes. Otherwise, you're bound to make more.
