do the Smart Pie 4 and Smart Pie 5 both take allow for a disc brake on the rear hub along with a 7 speed , have purchased the bike, and a battery on rear rack that I have welded some brackets to fit my mountain bike as it wasnt really made for it, but I am in a head shake moment as I cant decide what motor to use, Smart Pie keeps coming up trumps as it discreet as thats what I want, I don't want major power in th UK as I want to use this sensibly, I want a rear hub motor as they are pretty stealth looking and since I have purchased panniers to go over the rear battery you wont be able to tell its electric, as long as I don't have a monty python moment and speed past the local copper at 30mph with feet on bars lol
oh and what are the differences between 4 and 5 apart from bluetooth
and any chance of confirming if I eventually make my mind up and purchase the Smart Pie, until then just keep me as I am
cheers
