The Viking Safari looks smart, and works well as a basic bike to get about town -if you are not looking for the swiftest, smoothest, easiest, most effortless ride in the world. It's very good value for money considering the price of the competition, and it seems very solidly built. The folding and unfolding takes less than 30 seconds once you know what you are doing, and the kick stand, carrier and bell make this a complete package at a good total price. Assembly is straightforward -I did not do this myself but by all accounts it is straightforward.
On the negative side, this bike does feel heavy for something that is described as light, which was also commented on by friends who picked it up. It is not the smallest folding bike either when folded -the folding gets it into a car boot easily, but don't rely on it for compact storage in an office. It feels undergeared around town -top speed in top gear at comfortable pedal push frequency is not the swiftest, but will be fine if you are not in a hurry.
In summary -a great little bike if you are not expecting anything like the latest top of the range folding bike, but that's the trade-off on the good price this bike offers.
