Quad bikes

These two are generic 49cc ATVs converted to electric using automotive alternators as BLDC motors.

Power output installed in both is about 2 kw with top speed of 30km/h at 48v.Being an off road vehicles top speed was sacrificed for torque and hill climb using 1:7.23 gear ratio on 10 inch wheel.

Advantages of an electric ATV/quad bike are obvious:

– Massive start up torque , ideal for off-road driving.

– Quietness of operation.

– Reliability and minimal maintenance.

– Absence of hot running parts allows it to be used in bushfire prone areas.

– No exhaust fumes.

Thanks to the advances in lithium battery technology they have a practical driving range too.
