electric bikes are established technology
It always amuses me when there non-bike companies keep coming out with e-bicycle 'prototypes' and 'concepts', as if they are new and revolutionary. Generally these things are built by non-bicycle specialists, and are impractical and not well designed.
Meanwhile, established and respected e-bike companies are on their fourth or fifth-generation designs by now, have ironed out most of the issues, and concentrate on the stuff that matters (ride comfort and stability, smoothness of assistance, range and power optimisation, weight etc), rather than being distracted by radar sensors and vibrating handlebars or whatever.
I have a gazelle e-bike, and it is a joy to ride. The technology is impressive, although very transparent - you feel like superman riding these things, bowling along, up the hills - and it's only when you turn the assist off that you realise how much the bike is actually doing for you!
Given how much time El Reg devotes to electric cars, I'm surprised they don't do a piece on e-bikes. As an answer to the problem 'How to transport a single human being 10km to work each day' they are a much more logical answer than 'put him inside a two-tonne metal box that needs huge batteries and motors to make it go'...
