Sadly, the email address you gave me must have been stymied by a typo. So I am replying by blog!
You asked about bicycle hearses. So far as I know the only serviceable bicycle hearse in the country right now is that built by Paul Sinclair of Motorcycle Funerals. Paul is somewhat of a perfectionist, so you may be sure that his bike hearse has been soundly built. I see that there is no photo on his website at present, but you can see a pic of it at the top, taken from Paul’s newsletter.
I know of no other bicycle hearses, but it’s possible that some readers of this blog do, so have a look at the comments below. If you want to make further enquiries, perhaps your best bet would be to contact bike enthusiasts’ clubs like the CTC. You might also contact big bike shops like the Edinburgh Bicycle Co-operative.
With all best wishes,
