The Bird A-Frame Electric Bike combines sleek, modern design with practical urban functionality. Its lightweight aluminum A-frame provides a comfortable upright riding position and easy mounting, while the rear-hub pedal-assist motor makes longer rides effortless. Equipped with a 36V removable lithium-ion battery, it offers an ideal range of up to 50–60 miles depending on terrain and assist level. The 28-inch wheels with puncture-resistant tires, integrated front and rear lights, and LCD display ensure both safety and convenience for daily commuting. With a step-over frame, ergonomic handlebars, and comfortable saddle, the Bird A-Frame delivers an efficient, eco-friendly ride for city streets, college campuses, or leisurely weekend journeys. Buyers should note cheaper price as the bike displays error code 037, which indicates a fault in the rear hub motor wiring or internal hall sensors. The issue is likely caused by a damaged or disconnected motor cable or a failed hall sensor inside the hub. The controller may also be affected.
Parts that may require repair or replacement include:
Rear hub motor cable and connector
Hall sensors inside the rear hub motor
Motor controller (if the fault persists after cable inspection)
No visible frame damage has been observed. The issue prevents normal motor operation and causes the e-assist to stop functioning.
