Sorry for the late reply to a couple people. I went with the Pro Bike Tool xxl. It covers both bikes while on the bike rack.  I am not sure the xl would have been big enough. It is mostly designed for both bikes to be facing in the same direction, although it covers them when facing opposite on the rack. I don't need a cover for storage as the bikes are in the garage

Good evening.  I have been reading the posts concerning locks and have settled on either Abus or the NY lock.  My question is about shackle length.  Is there a shackle length that works best?  I have seen them ranging from 6" to 11.5".  I have a couple RadCity step thrus I will need to lock up ((separately).  There does not seem to be U-lock of sufficient width cover both frame and wheel.  Chain locks are can be quite unwieldy, but me be the only option.
Thanks for your input

Good evening to all. Hope everyone had a safe New Year
I was wondering what any one might be using as a travel cover for their bikes. We have two Rad City bikes we will be attaching to a Hollywood rack on the back of a motorhome. We would like to cover them from the weather and prying eyes. We have looked at a couple although nothing purchased yet.  We have also looked at sizing, according to manufacturers and customer ratings.  There seems to be a toss up between XL and XXL although XL seems to be more prevalent.
Any feedback would be welcome
Thanks

Hello to everyone. New to ebikes but have been biking for more decades than I care to remember. I and my wife have gotten a couple new Rad City bikes for fun around town and to carry on our rv. 
I have noticed what seems to be a pulsing sensation when in pedal assist mode (any of them) but not in throttle mode.  PAS seems to work but it is terribly annoying to be jerking along instead of a smooth ride.  My question is, is this normal, abnormal, something that goes away?  I have checked all connections, charged the battery. There are no error messages
Thanks for any feedback
