    I know that it is against the law to have a derestricted e bike on the public highway but why hasn't any attempt been made on the G-tech? Is there a crank speed sensor on the crank or is it sensing a target on the wheel? Is it restricted in the software?

    I am still playing with my Gtech due to dreadful weather restricting my use. There appears to be a learning curve because a “ push “ comes in at various speeds. When pushing hard up a hill there is no assist but ease off on the pedals and in it comes. Reminds me of an old peugeot505 with automatic but no kick down where you had to learn how to make it change gear by playing with the throttle. I would also welcome anybody with some technical info. on this bike and how it actually works.
