BH Easy Motion ride harsh?
I always thought and from reviews they are comfortable?
What do you mean harsh?
Is it jerky, noisy, etc.?
In my book ebike must be silent, zero noise, so I would never choose gear hub or BB middle drive.
My point is in many parks, pathways motorized vehicles are prohibited and the noise is real giveaway - you are on motorized ride!
But as you probably know cheap , primitive direct drive gearless brushless hubs can also whine like crazy and due to cheap controller jerk you - very annoying.
The only ebike drive I would recommend is FALCO , non-China edrive , designed in USA with 5-year warranty /!!!!/
Just Google FALCO, and you will see real silent, powerful, intelligent system.
Of course BIONX is obvious choice , used on many European and NAmerican ebikes. It is intelligent computerized edrive , great for exercise, very universal.
