I have the single bike Asgard one, which could actually hold both my 29ers easily enough if I wanted. It is tucked away quietly round the side of the house.
The single bike shelter needs a padlock and the hasp is 12.5 mm which means that it is just too small to take a Sold Secure Gold padlock, which all seem to have larger hasps, but which are required by many (most?) insurers. So if that’s all you do, an insurer probably won’t cover you. You could always have a ground anchor inside with a SS Gold lock but I can’t be bothered.
The 2-bike shelter has the same footprint as the single bike one, but has 2 compartments and a door at each end, so it’s effectively two independent shelters. It also has proper locks in the doors which meet insurers’ requirements, as do all the larger Asgard shelters.
Lead time on an Asgard shelter is a few weeks so you need to take that into account. I also paid for installation, which two very efficient lads completed in about half an hour.
