UPDATE:  I did call and they asked for a video of the noise and they immediately shipped out a new motor and credit to have it replaced with a local bike shop.

Gosh, that's good to know!  I'm going to call them now and see if I can get a replacement wheel/motor too.

Hey @bagrider91 and @Rover - which kryptonite ulock do you use?  I'm noticing most are not quite long enough to fit on the frame/wheel and onto a bike rack.

Hi - I had the same issue a couple weeks ago.  You can call RAD for a replacement or try the universal key everyone is chatting about https://www.ebay.com/itm/284725945597

@Ryan, this is so helpful having it in one comprehensive list.  Thank you sir!

I have the RR and City bikes too and the RR is definitely louder than the City.  The City bike is so quiet. As you mentioned is not overly loud and manageable but its good to know I'm not the only one.   

Super annoying since Im trying to track a previous thread in the general chat section

@radex5owner - For the Radrunner 2 bike

Thanks @JimInPT, Radrunner 2.  I did see those blank key options but seems to only work on the Radrunner 1.   I did order a replacement set online but customer service it might take awhile given the current sales event.  Hoping I can find someone with an F15 key to duplicate.  I got a Radcity 4 but those keys dont work on Radrunner 2.

Quick update: I was able to use a key from another Rad Bike (Radcity) by slowly inserting and turning and worked like a charm.  Its interesting the Radcity keys work just fine locking the battery but takes some extra loving care to unlock/turn on.

Hello Rad Family!  Lost my F15 keys and not sure how long it will take to get a replacement.  Anyone in the Bellevue/Seattle-area that is willing to let me borrow their keys so I can make a duplicate?  I am more than happy to provide proof of ownership of my bike to confirm its not stolen.  Thank you in advance.
