I got mine on ebay for about 75 euros a couple of years ago- there were quite a few being sold at that time and for that price I was willing to take a chance.

The handling of the bike is actually not as bad as you expect- a bit of roughness/debris/cracks is fine but I would hesitate to tackle any serious potholes/kerbs with it. If you try it I would strongly recommend a helmet.

For short distances (5 km or less) with some public transport it is OK. I put some folding pedals and a bag strap on it and it makes the bike quite useful (much more useful than those scooters). You can fold it and just carry it on your back like a long bag. There is no other bike I have seen that you can do that with.

It is not as efficient as a real bike though. It just depends on what type of journeys you want to make and your priorities.

Also you had better get used to lots of attention with it.
