Luke Breen & Mark Stonich showed the latest Evolution Products prototype. Evolution Bars for the BikeE on an adjustable reach stem. Bike-Es are designed with no tiller so adding even a small amount, and angling the grips down a bit makes the handling much steadier. One problem will be cost. Unlike the Rans LWB's, the BikeE hasn't got a fore and aft adjustable stem, and the cables aren't long enough to allow a change of bars. We're also working on a non-adjustable setup for BikeEs to keep the cost down. Better pix of the system can be seen here.
On the other hand, Rans LWBs have a lot of tiller. Not necessarily a problem, but the stock handgrip orientation makes it awkward to perform the larger steering corrections LWBs need for low speed balance. The Rans EvoBars are designed to correct this, and are selling well (mostly online).
