Do you ever intentionally use the "wrong" bike on your commute?

I destroyed a nice wheel set that way. Should I try again and expect different results?

I think I've had to use my bike that still had studded tires on it in the Spring when I had some issue with my other bike. I also remember wiping out on ice during my commute home because the temp dropped faster than expected after a late Fall/early Winter rain.

Both of those incidents were really related to wrong tires more than wrong bikes because at the time I had studded and non-studded tires for both of them.

You have more than one commutter bike

Nope.

My other bike would disappear, not worth the risk.

For me the only wrong bikes would be the mountain and cyclocross bikes. Not sure why I would ever decide to try and commute on them. If I absolutely had to use one of them, it wouldn't be fun it wouldn't be the worst ever. One day I might try it on the single speed syclocross just for the extra challenge

Almost daily. Fixed gear track bike with no rack mounts, no fender mounts, no bottle cages and won't fit anything larger than a 25 up front. Just cleared 2100 miles with it already this year and it puts a smile on my face every time I throw a leg over it.

I did once. December 10, 2013.

It was supposed to start snowing after 10 pm. The snow started at 4 pm. I was working until 7 pm.

Four inches of snow outside, and I had the bike with the summer slicks. Riding home with the bike in the back of my boss's pick-up, it ended a run of 1,596 consecutive workdays of bike commuting.

Well if that's the wrong bike, then as often as three days a week I do too, when I ride my Litespeed with full Dura-Ace.

There is no such thing as a "wrong" bike for commuting.

I usually switch to my 'summer' bike (Tarmac) in Apr and occasionally get caught in a rainstorm with no fenders. If it's raining at the start I'll take a bike with fenders.

Wrong bike usually in winter when not expecting snow but happens on the way home. But I usually err on the side of caution by taking the studded steed unless there's absolutely 0% chance of precipitation.

I don't have a "wrong" bike, but I have made some wrong turns. Usually on cool, clear, spring days when I don't have anything urgent at work. I've only been riding these routes for the last six or seven years, so sometimes my mind drifts and I forget to turn. Sometimes I have to ride five extra miles to get there! or 20 extra miles to get home.

All of my (too many) bikes are up for the task, given sufficient preparation, so no. I could even ride my track racing bike in (with added front brake) if I wanted to, though I haven't done it yet.

Have ridden on the same bike since I got it in '08. (V-Rex)

Define "wrong."

I have a purpose built commuter (with fenders, racks, comfy tires, long chain stays, and good luggage) but the only bike I want to commute on these days is an old race bike that has none of that stuff. Maybe the term "irrational" is a better choice than "wrong".

Aha! See, I don't even find that irrational -- if said "proper commuting bike" is too heavy and slow, you won't want to ride it on the nice days if you've got something zippier lying around.

yes. in fact i did it this morning. It was my other bike that has for wheels with an engine strapped to it...

9 times out of 10, I ride my race bike to work. Some might consider it the wrong bike.

I did once.....When I was 10,I rode my sting-ray 19 miles to the beach....Thought I would have to stay there forever....Wasn't the wrong bike,it was my only bike.

I still think it would be funny to ride around alone on the tandem...

...but I don't actually do it.

My 3rd year in university I went to grab my mountain bike to head off to a winter final, flat tire. So I grabbed the road bike. Made it to campus safely but on the way home the roads were iced up and I wrecked pretty hard.

Ultimately I think it's fun to switch bikes up for the commute. It keeps things interesting.

I almost always ride the "right" bike. Why? Because that's the bike I chose that day. No matter how hard, how slow or how crazy the ride gets that makes it "right" for me.

All my bikes 2 wheels with pedals. All work fine.
