the best SLA powered e.bike

[avronb]

I have just bought a used Izip Ezgo in ''as new'' condition of Ebay for £200,this is my first e.bike and so far i am happy with it,i will keep it for a while and because SLA batteries dont cost the earth(no pun intended)i shall trade it in for a new lead/ acid powered bike,this leads me on to the title,what is the best bike for me with this power source?.

I think xipi used to do 48v kits not sure if they are available still?

One other advantage of the lead acids - easier to charge by solar power
