I've been bicycle touring 2 months and a half (september till mid november) in central France, half of the time around 1000m elevation.
I've added a door to it, the OneWind Ultralight Ground Mat (size M), and it worked very good ! It really turns the Shelter into a mini tipi (as the groundsheet is not reinforced you MUST add elastic bungee cord at the four attachement corners). I've been into a violent thunderstorm, constant ligntning for 45 minutes, with strong gust of wind and heavy rain, and I was safe under the shelter, not a single drop of rain on me or my stuff.
If you need more height under the Shelter, simply add elastics bungee cords to all the attachment point, so you can have around 10 cm more height.
I also use the Shelter as a tarp above my 11 feet hammock, once again the groundsheet is required to add a little more length to cover it all (haven't tried under rain though)
A word for the cape function: It works well with a bike, very protective, BUT you need to get it attached to the bike with carabiners + elastics in front, back, and sides otherwise it will fly around. It's okay for few days of rain in a trip. In more rainy area you may want to consider a more heavy cape designed for bicycles.
I'm in love with this Shelter, it's very clever designed, I'm always surprised how this thing protects me, and makes a very small place anywhere in nature a home. I'm 1,87 m tall, of course I touch the sides both at feet and head, not a big deal if you have a synthetic sleeping bag, it dries very quickly. Or you can add a bivvy footbox to your gear.
See the pictures, it is remarquable how discreet this Shelter is, and how it can be pitch in absolutly tiny spaces.
Minimal configuration is 4 stakes, a walking stick and no guyline (even with some wind). That way it can be pitched in around 1 minute.
