Just watched the prototypes of the Brompton e-bike on TV. It appeared similar to the current offering from many on this forum,but they said it had been specially developed by Williams GP engineering.
The girl interviewer made the comment it didn't seem to be working,the MD of Brompton told her she has to press harder on the pedals to get more power....this lead me to believe they have used a torque sensor....I am surprised they have selected a torque sensor......most of my customers want maximum power with minimum rider input and therefore a speed (rotation) sensor is the simpler and preferred choice.
I realise that Brompton has a brand loyalty and is an immaculate fold but £2500 for a small wheeled folding e-bike ???
The timing is unfortunate,if the EU put 50% anti-dumping duty on e-bikes imported into the EU and the U.K. crash out of the EU and Liam Fox does a free trade deal from China then building e-bikes in the UK is going to be very difficult and the market very limited.
