My rear wheel came off?!?

Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.” -- Ernest Hemingway

My rear wheel came off?!?

I've got a 2000 Cannondale CAAD4 R1000. Today, I wanted to go for a ride. I put my left foot on the pedal and as I went to push off and throw my right leg over the bike the bike endoes and the rear wheel comes off! Has anyone ever experienced this? I thought the QR was tight. The bike is essentially new. I've had it since '01 and ridden it twice before yesterday. Anyway, now I'm a little hesitant to stand and pedal hard. I certainly don't want this to happen at speed. Are the Coda QRs that bad? Could new ones prevent this? Before today I never even imagined this now, I'm hesitant to get on a bike I now have plenty of time to ride!

I'm glad you and your bike are ok. I would have paid to see this though.

If you're QR is tight, there's no reason it should happen.

Maybe one side of your QR was caught on the lawyer tabs and kind of teetering on edge. When the bike went over, the thing just popped off. Did it do anything to the drive train since the rear wheel would've still been on the chain.

Standing and pedaling hard won't cause the situation you described if it feel off when the bike went over.

It had to be stupid funny! I ended up straddling the bike, seat in my back and the rear wheel laying flat on the sidewalk under the bottom bracket. I have no idea how I didn't just flip over.

The drive train seems OK. The chain was still on the rear cassette. The best I can figure is the force from the attempted downward pedal stroke pulled the wheel forward but that barely makes sense. I mean the wheel was literally snatched from the frame.

why do you say the QR was too tight? if it came off, the first thing that pops to mind is it's not tight enough. before you close it, when the QR tab is perpendicular to closing, there should be tension. then when you do close it, you should put the QR tab in your palm and your fingers on the spokes and clamp it down so it's real tight.

the park tools website has more info on working the QR.

There's an actual tab on my front. But not on the back. On my bike at least, there's a small lip there, about 1/4th the size of a lawyer tab.
The other theory would be the QR was sticking out and when he pedaled, he somehow slipped and hit it by accident, kicking his wheel out.

And mounting a bike 101.
Ensure that your start in a low gear.
Straddle the bike.
Put one put on the pedal at 3:00, Stand up, and as you go, you can take your other foot off the ground ounto the pedal, and sit down.

A bike is not a horse.

Do you mean I am doing it wrong when I run up behind the bike, jump from behind while slapping the saddle, and land in the petals and begin riding? It works for Silver.
