The K16 rides on 16 x 4.0 wheels against the K20's 20 x 4.0, which makes it a smaller bike suited to riders from 5 ft 2 in rather than 5 ft 4 in. It also uses mechanical disc brakes where the K20 has hydraulic ones. The motor (1500W), the battery (48V 20Ah, 960 Wh), the 7-speed drivetrain and the 330 lb load ceiling are the same on both. The K16 is $20 cheaper.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow far can the K16 actually go on one charge?\u003c\/summary\u003e\u003cp class=\"sb-a\"\u003eYVY publishes two answers on the same page. Its bullets claim up to 50 miles on throttle and 75 with pedal assist; its FAQ, further down that page, says 30 and 50. We print both because both are the manufacturer's. The pack is 48V x 20Ah, about 960 Wh — the same energy as the K20 — so the honest expectation is K20-like range, adjusted for however you ride.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat is the K16's top speed?\u003c\/summary\u003e\u003cp class=\"sb-a\"\u003eYVY prints \"28+++ mph\" in pure electric mode on a full charge. That is a manufacturer figure, not a measured one. On 16-inch wheels the same motor produces more torque at the rim and a lower top gear, so treat the number as the ceiling of what the controller allows rather than what you will hold on flat road.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eIs a 1500W electric bike street legal?\u003c\/summary\u003e\u003cp class=\"sb-a\"\u003eIt depends on your state. 15 U.S.C. 2085(b) defines a \"low-speed electric bicycle\" as having \"an electric motor of less than 750 watts (1 h.p.)\" and a motor-only top speed under 20 mph for a 170 lb rider. YVY rates this motor at 1500W, so its own figure sits outside that federal definition, and many states then treat such a vehicle under moped or off-highway rules. Check your state's rules before riding on a road or bike path.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eWhat height and weight does the K16 fit?\u003c\/summary\u003e\u003cp class=\"sb-a\"\u003eYVY's FAQ recommends a rider height of 5 ft 2 in to 6 ft 0 in for this model — the lowest starting height in its range — with a maximum load capacity of 330 lb. That load figure covers rider and cargo together.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eAre 16-inch wheels worse than 20-inch on rough ground?\u003c\/summary\u003e\u003cp class=\"sb-a\"\u003eGenerally yes, and it is geometry rather than opinion: a smaller wheel meets an edge or a pothole at a steeper angle, so it drops into gaps a larger wheel rolls across. The 4.0-inch tire width offsets some of that by cushioning impacts, which is why this is still a capable bike on gravel and packed dirt. If most of your riding is broken trail at speed, the 20-inch K20 is the better tool.\u003c\/p\u003e\u003c\/details\u003e\n\u003cdetails\u003e\u003csummary\u003eHow long does the K16 take to charge?\u003c\/summary\u003e\u003cp class=\"sb-a\"\u003eYVY states 4 to 6 hours at 3A — the only charging spec in its range that names an amperage rather than just hours.
