You know I'm not one to give the hard sell here, and I do not like banner ads, but...

Seriously I've just saved myself over £100 on a bike policy with Ebike.  My previous insurer couldn't get close.  Same bikes, same level of cover, fully comp, with business use, and then some extra benefits like free legal expenses, free cover abroad, and also including UK breakdown cover :)  £264 for four bikes (including 3 "big bikes" of 900cc to 1200cc).  That's really good.  It could have even been a touch cheaper if I'd opted for a greater voluntary excess.  Mind you, I'm getting older now, with a lifetime's no claims bonus, clean licence, good locks (good looks?) and a secure garage. 

Try them for a no obligation quotation.  It worked for me.  Click here or the link below.
