Federal law (15 U.S.C. § 2085(b)) caps a low-speed electric bicycle at under 750 W; Eunorau rates this bike at 1,500 W combined while publishing a speed-limited 20 mph Class 2 mode. States that write their limit on motor output will treat it as above the line. \u003ca href=\"\/blogs\/journal\/electric-bike-laws\"\u003eOur state guide\u003c\/a\u003e has each one. For a bike inside the federal definition, the \u003ca href=\"\/products\/eunorau-defender\"\u003eDefender\u003c\/a\u003e is 500 W at $1,599.\u003c\/p\u003e\n\u003ch3\u003eAre dual-motor e-bikes worth it?\u003c\/h3\u003e\n\u003cp\u003eFor grip, yes — and that is the reason to buy one, not top speed. A driven front wheel pulls the bike straight on sand, snow and loose gravel instead of pushing wide while the rear digs. On dry pavement a single motor does the same job for less weight and more range, which is why the 1,500 W is a traction argument here rather than a speed one. \u003ca href=\"\/blogs\/journal\/dual-motor-ebikes-usa-2026\"\u003eOur dual-motor guide\u003c\/a\u003e compares them across brands.\u003c\/p\u003e\n\u003ch3\u003eWhat is a torque sensor, and does this bike have one?\u003c\/h3\u003e\n\u003cp\u003eIt has a bottom-bracket torque sensor. A cadence sensor only knows whether the cranks are turning, so assist arrives in a lump a moment after you start; a torque sensor measures how hard you are pressing and scales both motors to match, which feels like strong legs rather than a switch.\u003c\/p\u003e\n\u003ch3\u003eHow far does the DEFENDER-S 2.0 go on a charge?\u003c\/h3\u003e\n\u003cp\u003eEunorau rates it at up to 40 miles from the 48 V 15 Ah pack — 13S3P of 21700 cells, 5,000 mAh each. Two motors draw more than one, so treat 40 as the rated ceiling and expect less into a headwind, up hills, on soft sand or at rider weights near the 300 lb limit. If range is the priority, the \u003ca href=\"\/products\/eunorau-fat-awd-2\"\u003eFAT-AWD 2.0\u003c\/a\u003e is rated to 80 miles on two batteries.\u003c\/p\u003e\n\u003ch3\u003eWhich frame size should I order?\u003c\/h3\u003e\n\u003cp\u003eEunorau publishes a recommended rider height of 160–193 cm (5'3\"–6'4\") for the 17\" frame and leaves the cell blank for the 19\". It publishes seat height for both: 585–735 mm (23–28.9 in) on the 17\" and 635–785 mm (25–30.9 in) on the 19\". Riders at the tall end of the range who want more seatpost and a longer 655 mm top tube take the 19\"; everyone else is covered by the 17\". Not sure?
