What materials are used for the AVDLBIKE A51 mountain Ebike frame?
Most ebikes on the market use iron to make frames. Why A51 Ebike Uses an Aluminum Frame Instead of Iron
1. Lightweight: Improved endurance and control
The density of aluminum is only 2.7g/cm³ (iron is 7.8g/cm³), and the frame weight is reduced by 40%. Reduce the motor load, increase the endurance by 8-10 kilometers; at the same time, improve the acceleration response and steering flexibility.
2. Strong corrosion resistance: double the lifespan
The surface of aluminum automatically generates an oxide film, which resists moisture and salt spray corrosion, and does not require anti-rust coating. Iron frames are prone to rust and require regular maintenance. Aluminum frames extend their lifespan by 3-5 years in rainy areas, and have lower maintenance costs.
3. Eco-Friendly and Recyclable
Aluminum is over 90% recyclable and uses far less energy to reuse.
How many suspensions does the A51 adult mountain Ebike have?
A51 Ebikes include rear suspension and front suspension, known as full suspension or dual-suspension.

MODE 1
Assisted mode / EAS (MODE A-1-2-3 ).This e-bike provides a unique assisted riding mode. Turn on the power and pedal the pedal like a regular bicycle. This e-bike will detect the pedal signal and automatically provide electric assistance. EAS (e-bike assisted-mode system) will intelligently determine the assistance ratio based on step frequency (RPM), and the faster the RPM, the faster the cycling speed. When on an uphill, maintain the low to medium speed pedal frequency, and EAS will automatically adjust the assistance ratio to stabilize the speed at 3-5 mph.
MODE 2
Pedal mode: Turn off the power, and this bike can be ridden manually like a regular bicycle.
MODE 3
Throttle mode: This e-bike can control the speed through the throttle and ride in a pure electric way.
