Look at the bottom photo above, I do wish I had managed to get a photo of Kel towing megatrailer out of the driveway during that house move. She went a bit fast (despite my advice) and the bump lifted her back wheel off the ground. Predictable results. Followed by this look of intense anger-and-laughter when she realised she was unhurt but looked really stupid.
@Criggie I tend to get involved with women who are, at least initially, whole and healthy. Although, I hasten to add, most of them are still alive now. And the ones that aren't, were nothing to do with me.
mostly you just stop, coz there's no momentum in the wheel, but then you have the problem that you're doing a trackstand unexpectedly...
Better than mag/wind trainers where the failure mode is normally that the wheel stops going round coz it's wedged into the machinery. Or bits go everywhere and you lose all resistance. I've done the latter, it was survivable but my crotch barely escaped the top tube. Lockup failure was worse, I destroyed a bunch of expensive toys at a trade show.
But then, who goes to a trade show and says "put as much power in as you can, our machine will take it". I mean, it's obviously what they're selling, but bicycle trade shows are where stupidly powerful cyclists go because either they're being sponsored or because they've retired and work in the industry now.
So if you ever wanted a place to find out what happens when someone dumps 2kW into your training aid I suppose that's the place to do it. But you might also want to set the gear up so that when it fails you're not left trying to catch a 40" TV that someone just head-butted.
I had a design for a fan that ran off the trainer, but there are a few issues with physical size and whether you really want a 90cm diameter 3 bladed fan doing 10rps in front of your face. A squirrel cage blowing up at you is probably safer :)
A squirrel is actually easier to work with because the axle runs the right way for a chain drive. Smaller is also handy. And burning 200W or more for a fan when I have 200W of me-power right there seems silly.
@alex that's magic. I want one... if I used rollers I'd buy one. And the tandem extension would probably also work for my recumbent and shopping bike. That would be hilarious, riding a long john on rollers
Weird - I was sure I did an answer to this question , suggesting a magnet to decide if the frame was steel. http://bicycles.stackexchange.com/questions/39253/upgrade-compnents-to-fix-everest-brand-bso-mtb But the answer is not there, its not even listed as deleted. Any ideas?
