Hi,
As a context:
* I've live in Lisbon area (a lot of hills),
* I'm after 40 with 90 kg weight
My daughter is an active 7 years old kid and at some point I wasn't able run as fast as she rides a scooter.
HB was designed to be used for short distances (less than 15-20 km).
* Learning basic driving on the HB turned out to be child's play;
* HB is a lot of fun to drive;
* HB It is perfect as a companion for kid on scooter;
* HB It is beautifully and minimalistically made;
* Riding on HB allows you to get tired / exercise :]
As a cons: unlike a bicycle and unicycle, your hands must be on the handlebars, the descents are terrible, you need good quality roads to enjoy the ride.
Unexpectedly, I had the opportunity to damage the bearing in the rear wheel. The contact with halfbikes.com was great, they helped, took care of me and my HB. Customer support and service: Great!
