Backed by a high-capacity removable \u003cstrong\u003e48V 20Ah (960Wh) battery\u003c\/strong\u003e, it provides an impressive pedal-assist range of up to \u003cstrong\u003e70 km (43 mi)\u003c\/strong\u003e. Unlike entry-level e-bikes equipped with basic cadence\/speed sensors that suffer from unnatural pedal lag, jerky power surges, and wasted battery energy, the HQ20's intelligent torque sensor continuously measures your actual pedal pressure in real time with millisecond precision, delivering instantaneous, silky-smooth proportional assistance that feels completely intuitive—like a natural extension of your own legs—while boosting energy efficiency by up to 25%.

The HQ20's intelligent torque sensor continuously measures the actual pressure of your feet in milliseconds. It provides instantaneous, silky-smooth proportional assistance that matches your exact pedaling effort. This makes starting on steep hills effortless, improves riding safety at slow speeds, and boosts overall battery range by up to 25%!\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Is this electric bike street-legal in Europe?\u003c\/strong\u003e\u003cbr\u003eA: Yes! The CMACEWHEEL HQ20 is fully configured for European road compliance, featuring an EU-compliant 250W continuous rated motor, a factory speed cap of 25 km\/h (15.5 mph) in pedal-assist mode, and a disabled twist throttle.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the maximum speed be unlocked and can the throttle be activated?\u003c\/strong\u003e\u003cbr\u003eA: Enabling the twist throttle and unlocking speed up to 42 km\/h (26 mph) is strictly permitted and intended ONLY for riders and destinations outside the European Union. Within the EU, the throttle remains disabled and the speed remains capped at 25 km\/h to strictly comply with European road regulations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What are the benefits of a low step-through frame?\u003c\/strong\u003e\u003cbr\u003eA: The low step-through frame eliminates the high top tube, making getting on and off the bike effortless and safe, especially when carrying groceries in the basket or transporting cargo on the rear rack.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can the battery be removed to charge indoors?\u003c\/strong\u003e\u003cbr\u003eA: Yes!
