My father has had his Twike for seven years now. I wouldn't recommend it, the suspension is not up to snuff, even just for daily commute. Getting repairs done is a major difficulty as there are very little parts or mechanics readily available. He also had to sue the Twike company when they tried to defraud us w.r.t. warranty and insure documents. The legal issues have been on-going and they stalled the repair of the Twike for about a year.

My father now commutes by electric bicycle.
