Welcome to the forum, hope you become an owner soon.
A few thoughts on your questions:
1.What are the benefits.
Fun & a Happy Feeling while gliding!
No road traffic/congestion to mess up your day.
Great for small item trips to the store and work commuting.
Did I say FUN!
2.Do you feel satisfy with the quality of the product, is it cost effective?
Quality is excellent. Well designed and built for the primary usage.
Was not purchased on a cost analysis or cost/benefit comparison to another form of transport. Segway is a toy that can be used for some practical applications; for example commuting.
3. If we buy a Segway will I have assistance post purchase. Did you guys for instance, had a sort of training on how to use it?
Dealer can provide 20 minutes of training that's all you need.
Owners manual also has several tips on how to best control the machine.
Plus there is a leaner mode so you can adjust the machine speed of response to your skill level.
I've had no issues that would require post purchase support.
4. I just learnt yesterday that I cannot use the Segway on the road here in Madrid, I assume I can use it in pavements but my friend tells me in London you can't. I think this is a problem.
Do your research on local/regional/national laws for the areas you plan to operate.
Ask your dealer but double check with your research.
In U.S.A. There are national, state, and in some locations city laws on operation.
For example:U.S.A. National. Segway type machines are not classified as Motor Vehicles.
Same is true for the States however there are differences.
Texas says a Segway must follow Bicycle road rules.
- Travel with traffic on roadway, use bike lanes.
Washington state says a Segway must follow Pedestrian road rules.
- Travel facing traffic on roadway, use sidewalks (pavement) when present, do not use bike lanes, can use bike trails.
In addition many cities have outlawed usage in downtown areas.
There is only one distributor here in Spain so I have not many options, can I get it directly from the manufacturer?
No idea on current purchase/delivery methods.
Good Luck with School and you Segway Adventure.
