true,however if you have a lightweight bike with a 2x11 you could probably sit down and do most hills,there is one other considertion seating posture and hip foot alignment,standing up kills me if i cant pull it sitting then i twist the throttle,the only point being made is you can really lighten a bike if it doesnt have electronic cpmponents,my next bike is either going to be a reverse trike or 7s propella have about given up trying to build my dream bike,back in the day wasnt no shame pushing up a hill.used to bug the guys that were pushing by remaining seated and pedaling by them on an old steel frame western flyer,i guess i had more torque then hp.that was 50 years ago .
