Ridgeway.
http://city.portcolborne.on.ca/visit..._do/for_a_day/ Port Colborne Tourism may be a help. Their website calls it the Ridgeway Ramble.
They suggest the trail ends prior to Port Colborne, in Ridgeway. You of course will be going east to west. Hope you have a nice ride.
The Niagara Parkway (north from Fort Erie toward Niagara Falls) is a very popular route, but you probably already knew that.
