Says the man asking about boot dryers. What’s wrong with newspaper and a radiator/airing cupboard?
I was waiting for this 😉
The thing is, shoes need to be dried* Bikes, definitively, do not. Especially, and ironically, high-end mountain bikes which have excellent sealing against water on any part that needs it and everything nut and bolty is made from stainless steel.
Dogs do, agreed, but that can be done with a towel. And if you’re that precious about your bike, well, firstly FFS, and secondly that also can be done with a rag/towel.
* and, yes, I could stuff them with newspaper and stick them on a radiator, but then you’ve got unsightly, horrible, muddy shoes on your radiators, which isn’t great. A shoe dryer can be bunged somewhere discretish and left to get on with the job
