I noticed a website for a company on my doorstep selling conversion kits and converted Bikes, I took a quick visit today, these guys are serious operators, obviously having other Business interests, they were loading a truck with 200 converted bikes for a Polish Customer, in talking to them they have not advertised in the UK but they are now preparing to trade in the UK - big time I think..I got offered a job !!!! Converting bikes is not for me but if anybody fancies it you could contact them electricbike-conversions.com
