I really like it ... the advantage of the r3 is its excellent uphill ability even I used to pull a friend on a bike ride..good battery life along with that is easy to balance .. the brakes on the r3 are also very safe of course with a bit of a compromise as the k-wheel moves well on rough terrain..that would be nice if it could be replaced by the off-road wheel.

Very smooth with long range. I rode for an hour and it uses only half of the battery. My friend learned to ride on my longboard very quickly, good for beginners as well I think, so much fun!
