The Windhorse W4A is a 20 MPH electric bike built around a 720W brushless motor that peaks at 983W and a 48V, 748.8Wh battery. Windhorse claims 55–70 miles of pedal-assist range and 40–45 miles on throttle alone, with five riding modes and a seven-speed drivetrain for hills and varied terrain. It suits commuters and trail riders who want long range and strong power without stepping up to a heavier moped-style e-bike. Against rivals in its class, the battery capacity and peak output are generous; the trade-off is weight and a single frame format rather than a family of models.

Owners rate the W4A highly, with 4.7 out of 5 across 856 ratings. Praise centers on range, motor power and the smooth five-mode assist; the main complaints are weight and range falling short of claims under heavy throttle use.
