KidBriar,
I hope you are happy with your Powacycle
Flecc,
I think a better way to think of it is that the Powacycle is a pedelec, rather than an e-bike. However it also has a throttle boost, which you can enable via the switch. As such there is no throttle-only mode.
When I ride my wife's Powacycle, I always have the switch on, so I have the option of twisting the throttle for a quick spurt of acceleration.
Having tried both, I prefer this system to the Powabyke/Ezee system where you have to keep the throttle twisted to get any power, even in pedelec mode, as it is far easier on the wrist.
Ideally you might want a switch that gave you the full range of options, ie:
1. pedelec mode not requiring throttle but throttle boost enabled
2. pedelec mode not requiring throttle but throttle boost disabled (ie pedelec as defined in EU regulations)
3. pedelec off - throttle enabled (ie e-bike)
4. pedelec off - throttle disabled (ie 'off')
The Powacycle switch gives options 1 and 2 (and 4 if the battery is switched off), but not 3. My Powabyke (I believe Ezee is the same) has options 3 and 4, plus an additional one (that I don't think many people use) of a throttle that only works if you pedal.
These things are much more complicated when you try to describe or visualise them than they are if you sit on the bike - I am sure you of all people would not find it confusing if you rode one!
Best,
Frank
