Gtech known for their cordless vacuum cleaner, has just launched their first ebike. Notable features are 16kg weight, no gears, no chain but uses carbon belt, and custom bottle battery with builtin controller. Looking at the videos and comments it guess it maybe a torque sensing. It cost £1695 and their are two version, a sports and city, seems a pricey for me but does like good. They have a 14 day trial with free return if someone may like to try it out and report back here on the performance.
