Got my halfbike3 back in June, was easy to assemble(thanks to YouTube video), took me some time to learn how to ride it properly. My feet size is around uk44 so sometimes the back of the sole may scratch the ground/back tires. Still a lot of fun riding it and can manage doing an 8 turn within a smaller space now. The other thing I found is that as it’s a standing bike, riders with big feet may want to ride it with harder sole shoes to avoid soreness/tiredness in the feet while/after riding. Anyway to sum it up, it’s a very good bike to play with!
