I bought 2 Rad City Step-Throughs for my wife and I earlier this month. With limited room in our garage, I needed a better option for storage as I was constantly moving the bikes around to get to my work bench or to get the second car out. My solution was a Rubbermaid 7x7 shed that was just the right size for the bikes and could still fit in the space I had available. $700 delivered, and it doubles as a storage shed for my grilling/smoking supplies and cast iron cookware. There's ample room for two shelving units and the bikes.

The bikes are locked together and the batteries are stored inside the house to deter theft.
