Helpful Video About Throttle PAS

The industry should just call a throttle an "infinitely variable assist." So we can just call all ebikes pedelecs. Since ebikes like the Footloose have pedals (considered functional) that only drive a generator this doesn't seem to be a major loophole idea. The problem with all programmed assist drives is that they simply can not provide the desired assist for all riders under all conditions (the programs all fall short in my opinion and I've ridden all of them). Using an Infinitely variable assist / throttle I always get the assist level I want and I'm always pedaling to get the benefits of riding a bike.

I found that video more harmful than helpful as it perpetuates the concept that throttles are there to be used in lieu of pedaling as he demonstrates several times. When in fact it can be used to good effect, especially with a cruise control function, and by this I mean the ability to set the motor wattage at a constant, to allow the rider a more natural pedaling experience and the ability to shift gears as necessary if there is no effect on the drive train tension due to PAS's which at higher cadences to me start to feel too vague. Just because you are turning the cranks doesn't mean you are getting the full benefit of doing so. But whatever gets you down the road I suppose.
Sadly you are probably right - the typical intellectual level of our society makes it challenging for many to comprehend that riding a throttle ebike like a moped will reduce battery range and provide no health benefits of riding a bike. But hey, there are people that think they'll look like a super model if they buy their fashions and make-up while being 50 lbs overweight.
My big issue with pedelec programming is that even though I'm an engineer I feel that it's engineering egos driving the idea that using torque, cadence, gear, and/or speed sensors feeding a program can actually do better than a throttle. I'm not saying they are not "effective enough" for most riders but they simply are not as good as the old school throttle that allows the rider total control of the assist level.
I have two engineering friends that literally told me they could fix the shortfalls of the current pedelec programs but when I asked them for details it was clear they were clueless...their egos just got the best of them.
Here's an example of a problem with most pedelecs...the assist is prioritized on crank torque from the rider but an elderly rider that has bad knees may not be able to put much torque into the cranks such that they never get the assist they need (likely never to get the achieve the full assist capability via the programming on most ebikes). Strong riders can get full assist but they don't need it as much as that older rider with bad knees. Want to see a Bosch engineer run and hide under their desk ask them how to solve this...
Jeez, it's just a video about Evelo's assist and throttle, if you like pedaling so much why even bother with an electric bike??? I have an Aurora with this system and don't need to worry about shifting because it's electronic with a CVT rear hub and it works great!
The reason I got a bike in the first place is because it has a motor! I love being able to hit the throttle when I want and take off with ease on hills. I thought the whole idea of the ebike was to add power to a otherwise pedal bike. I am not trying to fool anyone, I ride my bike Because It's Electric powered, no apology here I enjoy it to much.
I have a regular bicycle and seldom ride it as it is getting hallrd to hit the hills anymore, but now I can go for miles and miles with no problem. I can still get a good workout on my bike , I leave it in level 1 and pedal along at a steady pace and can feel the benefits in increase heart rate etc. and my legs get a good stretch as well.
I had another bike with no throttle and I missed it. Sometimes in a busy intersection it's nice to just lift your feet onto the pedals and roll the throttle moving instantly across and then when clear begin to pedal. Mine will go to 28 mph on throttle alone. As far as range is concerned it doesn't matter much to me because most of my trips to the store for grocery runs are only 2 miles and sometimes cruising along without pedaling is great, several trips a week takes weeks for the battery to get down enough to need charging. On longer rides I just don't use the throttle and stay in pas 1 usually.
In my thinking the whole reason behind having an electric bicycle is the motor! else it would just be a regular bicycle.

Jerry,
I hope my response was not mis-interpreted. I very much like throttle-based assist systems on ebikes because they allow the rider to get the exact assist they want all the time (the PASs fall short of doing that in reality).
...that said I still believe that a rider should stay engaged and pedal (most of the time at least) even if they utilize the throttle.
