For a couple years I would do the shortest distance of 12.5 miles one way riding my DF bike, then, E-bike, then trike, then Veolmobile. I was using the Velomobile for all my commutes except when the weather was to bad to take it and I would take the E-bike with studded tires. Since I am using the Velomobile all the time now I go a different route which is 18 miles one way but only takes me about 5 minutes longer than the 12.5 mile one way route, so I choose that way. If the weather gets to bad I will go back to the 12.5 mile route and use the E-bike.
