I guarantee the Trek Pure and KHS are completely heads up and flat foot. I'm trying to find the picture of the Townie I converted. If you can find ANY of the Trek frames named in the suit they are also FABULOUS flat foot frames. My KHS achieve the Townie ride but as I wrote they messed them up in 2016. I bought one and committed before I realized the changes. SO I'm upgrading the brakes, wheels, handlebars and seat.As an ebike consumer and enthusiast, its unfortunate Electra has a strangle hold on cruiser style ebikes able to be built without a true upright, relaxed riding position crank forward design for proper leg extension allowing to plant our feet flat on the ground whenever we want without leaving the saddle.
Crank forward design should be an industry standard on all cruiser ebikes, but as you stated earlier, Trek was trying to bring its customers more comfort and control and were caught infringing on Electra's patent. Sad.
