In reply to Yanis Nayu:
Apparently he aroused suspicion by changing from a 6k carbon bike to one with a cheap steel frame, yet his results improved. Also it was noticed that one of his bidons was always in the same position. And one cable too many!
Which leaves the question of how many people have taken a few simple steps to conceal things better.
Back to the OP though, I’d also be interested in knowing whether the bike conversions work. For my wife obviously. Who has a decent full suss but she hardly uses it due to the hills in Sheffield. Test rode a couple of e-bikes last week and was very impressed. But 3k is a lot to pay
