You'd still be able to use a throttle to control the amount of assistance you get, that wouldn't be affected by the proposed changes.I think a lot of people on this forum like to pedal,but most of the bikes i have seen locally were crawling along with no attempts to pedal at all,personally i pedal almost all the time but enjoy the option to use the throttle if i need a short rest, and also to control the amount of power i want to add to my pedalling.
You'd even be able to rest and let the motor do all the work, just so long as you continue turning the pedals. There's nothing in the proposals about a minimum level of rider input (as there in in Japanese law), so riding under throttle while you pedal air would be allowed.
Like all good compromises having a system that requires pantomime pedaling to keep the motor running isn't something that anyone really wants, but it does help make the distinction between electrically assisted pedal cycles and motorcycles almost logical.
