No, "A", I was responding to the post right above mine, who quoted me, and did not like what I posted.
He was comparing me to someone else who insists his bike is the bestest ever, something I have NEVER done.
You have large crowds, while I, and many, many others, do not.
You have small apartments, while I, and many, many others, do not.
You have significant hills, while I, and many, many others, do not.
You have potholes and rough roads, while I, and many, many others, do not.
There are different strokes, for different folks.
There is a man, driving in my state, he was on 60 minutes, had some sort of neck issue and could not turn his head to the left. He drives his car, and if his wife can not go with him, he just does not look to the left. I got lots of those. Blue hairs, FOPs, they are dangerous and I am actually giving some thought to the pool noodle. Low to the ground moving targets are not safe here.
I built my own, using a Walmart Denali as the donor bike. Added a lightweight front motor, controller and minimal display, rack and battery. Whole thing is less than 50 lbs, including lock and flat kit. Chose my motor very carefully. Could not find a user report of anybody breaking one. Spent a year or two researching and making a decision. Looked at EVERY POSSIBLE option. Eliminated weight, unneeded complication, failure points. Reliability and ability to get home was extremely important to me.
This motor, and bike, have never left me stranded. No replacement parts other than tires, tubes, brake pads. No expensive or proprietary parts on it. Have replaced the battery, changed from similar but heavier original donor bike several years ago. Total 8 years, roughly 25,000 miles.
I MUST lift my bike, frequently. I have a slow pedaling cadence and NEED to pedal regularly, but not all the time. So I need tall gearing, 48-13 is barely acceptable. Wanted to do a front wheel install as simplest, easiest, no interference with drivetrain, no changing of gear cluster. Denali has Steel front forks, straight uncurved blade, with a hole for front rack mount which can be used for a torque arm. Tall gearing.
Plus, I rode an unpowered Denali for several years, worked well, no issues, well suited to my needs and my environment and riding style.
Putting a small, geared hub motor in a 700C wheel is universally recognized as a bad idea. UNLESS - you have flat roads and no hills, and pedal only on takeoff. No suspension at 20mph is also a known bad idea. UNLESS you have smooth roads, sidewalks, back alleys, and wheelchair ramps everywhere, and never ride off-road.
Primary starting point for earlier post was people wanting folders for lightweight reasons, and I was pointing out there are other ways to achieve that.
People tend to get fixated on only one way to solve a problem, and also do not look at potential future issues which could be avoided.
