call it what you want , for me im almost 50 rode my first bmx in the 70s raced moto x 250 cc and 500 cc class from the age of 11 to 18 , got onto downhill at the age of 40 . knees are fucked so is my neck and lower back , i should be sitting in the pub wasting my life like most 50 year...
yes the good side of having a piggyback battery is maybe one day they will make a 700 w battery that will slot straight onto the bike , having it build into the frame makes the frame fricking fat and ugly and no option to add a fatter battery later
when ur talking 2.8 to 2.6 ur talking about a few mm , it would be better looking for a better tread and side wall tyre , watch this vid from the 1.30 mark
