Thanks for all the suggestions

Thanks to everyone who replied
We decided on the Mini s/t
Was pleasantly that they arrived in 7 days and even I was able to put them together
Unfortunately as we live in Barrie Ontario ( in the snow belt area ) we will have to wait for better weather till we are able to do our maiden voyage. 

Anyone have a recommendation on which helmet to purchase

Been checking out helmets
Does anyone have a recommendation

I read yesterday that the Mini rear rack was available however when I tried to order one I was told that they don't ship to Canada and that I should contact
Rad Canada ( I hadn't realized that the link I used was the USA only )
I tried to order one through the Support Centre ( telephone ) and was told that they were unable to help
I was asking if it was also available in Canada therefore their response seemed odd.
Has anyone in Canada been able to order one since they announced that they had them in stock again

On a more positive side I ordered two Rad Mini step thru's on Dec 15 and received them on Dec 22   

We are looking for advice on choosing the best bike for my wife
We are undecided between the mini step thru 2 or the city 5 plus step thru
We are seniors ( 69 ) and my wife is 5ft in tall
If anyone in the group of similar height and age group has either of these models we would appreciate your thoughts
Thanks
