So I received my DS last week, via Capitol Motosports in Winnipeg, and it is quite impressive. Capitol was very helpful; they even helped me put together my newly-purchased hitch carrier (I was originally going to borrow my Dad's truck, but it didn't work out that day, so I quickly stopped at Princess Auto on my way there).
I was crazy busy the day I picked it up, so my first ride was at night - a perfect evening with way above seasonal temperature. I instantly fell in love with its quiet hum and zippy acceleration. If it didn't have headlights automatically on, it would be the ultimate stealth ride
My kids absolutely love it - my 18-month-old is addicted to rides. One afternoon they took turns riding on our back lawn, and she cried every time I took her off, so we ended up with her in front and my older kids behind! I like the fact that I don't have to worry about hot mufflers, crazy vibrations and noise, or smelly exhaust.
I have done a bit of trail riding in my bush, and although I made my trails for mountain biking, I found that it is doable with the DS. This year I'll make them a bit wider and try to get rid of more brush. I have the belt drive so I'll stay out of the really heavy mud - I don't mind; I much prefer the low maintenance and low noise.
I plan on using it mainly for my 34-mile round-trip commute to work, so I'll post in a few weeks how that's going.
