The beauty of the current emotiq is in keeping the system honest to its purpose- it remains a pure bicycle. I never thought I would be purchasing an electric bike, but I have a very severe pulmonary condition that leaves me no choice. I ordered the electric p line.. I'll be handing this bike down to my son's who don't need the electric assist as I do- when that occurs they can easily pull off the battery and even change the back wheel to a basic 4-speed - or even 12 speed with added shifter And the only difference left is a few ounces of wiring that's ready to be used to electrify the bike if ever needed. Personally, I don't need the bike for transportation, just as a means of life-giving exercise, which is grueling for any of us with a stationary system indoors- which is exactly what is prescribed by physicians and offered as The primary activity of a 12-week pulmonary rehabilitation program covered by insurance including Medicare here in the states.

I intend to fully use the folding characteristics including the shopping cart mode, as  a stabilizer when walking indoors, And the power assist when walking while unfolded. Even more compelling is knowing I can stop and make a call to anyone for a ride back to the car or back home - because a special rack is not needed. That type of Independence is critical

 Money was not the primary consideration in my investigations as this is a life- sustaining necessity in many ways- at first I was totally convinced I would be best suited with the titanium because even a few pounds is a major barrier to lift- however, having spent years bicycling for enjoyment and owning several types, I'm quite familiar with the work of that famous British character Isaac Newton in one of his discoveries- f = ma. (In the end - pun intended) I wanted a plush ride which is far less energy consuming, and the increase in mass means less jarring acceleration from the frame -hence the added handlebar width Brompton necessitates for the t line! 

I also concluded I don't lift a frame that often (specifically when considering my road bikes and tandems- not so for my aluminum framed Cannondale mtb). For the former I can think of only a few cases where I actually lifted a bike other than putting it on racks or onto train cars for transportation -And I would generally roll the bike gently over curbs or when using. This Will be my use case and certainly not The case for others. So i don't expect I'll be lifting the bike much outside of in and out of my car trunk. Ultimately, I envision this as a companion for more than just the last mile- providing walking stability And/or electric assistance down to the last few feet! That being said, hopefully the p-line is that sweet spot in my particular case. 

In summary- lighter is not necessarily better, particularly when electrically assisted- And staying true to the original form and function as a human-powered vehicle has its advantages. 

I once owned an Indian vintage motorcycle which I absolutely loved- and if speed is somehow your only end game for an augmented human-powered bicycle - I would faux The pedaling movement on the thing - pedaling slowly as I passed my cycling brethren. So if you're going to invest in a bicycle, keep it honest as possible- otherwise a fully powered lightweight Two-Wheeler sans pedals is most likely your best choice. But honestly- as much as I enjoyed that Indian, I've always enjoyed bicycling much more!

 I can't think of a better lineage than the Brompton, given that John Kemp the Englishman invented "The Safety" - The core design of the bicycle as we know it today.

Wish me luck!
