i have a rad city 5 , for sale needs some work but minamal needs both brake levers and right side gear changer ,  there is no charger evrything is in 10/10 condition other then stated .  its never been left outside , always stored in garage no sun fading tires mint . i bought it off marketplace on a whim id fix it but just dont have the time nor interest honestly .  i live in Ontario Canada and depending on location would be ok to ship . ..make me offer today ....be nice and respectful and we make deal today

so i bought a rad city 5 used online and it needs some love ,  it did not come with a charger iam told battery works tho . also both brake levers are broken and the gear changer was missing right hand side . 
then i had a friend say i wont be able to use it because there is no key ?
is this true i was not told nor given a key and i do not see where one would go . .
please can someone point me in a direction on what i should do about this .  is my bike now useless or am i able to get the parts needed maybe used or could i buy replacement from the company its made by .  please say i did not waste 500 on something i cannot use as an electric bike ....

hey guys so i have the rad city 5 i bought second hand on facebook marketplace and i have to replace the rear brake lever and gear changer on same (right side) now i also noticed the same little cable at first had no idea where it went as the brake lever was broken and not attached to bike . so its a sensor you said .  now could i just not use it or do i need to buy an original lever , i do have other levers here but none like the one it came with .thank in advance
