## What reviewers say

**NIU KQi3 Pro** — Only one whitelisted tester, TechRadar, published a hands-on review of this exact model (NIU KQi3 Pro, first reviewed November 2022). It earned Editor's Choice with a 5/5 total, praising shock-absorbing 30%-fatter 9.5-inch pneumatic tires, snappy performance with a 20% hill-climb rating (held 7-9 mph on a steep grade), unusually easy assembly, and strong $799 value, while flagging that it's heavy and not portable (44.75 lb), only IP54 water-resistant, and has very responsive brakes.
