Enhancements
On the Speedway Mini 4, the folding

Both the front and rear suspension have
been significantly enhanced for improved

impact while riding), along with tightness of
suspension nuts and bolts.

handles. Rear Brake Deceleration
Always decelerate before coming to a complete stop. Practice safe
braking by decelerating with rear brake lever first, coming to a gradual
and complete stop.
Rule 3
Electric Braking and Deceleration
When you enable the electric brake and set brake strength on dashboard it enhances the effectiveness of the
stopping distance. If enabled, when applying the brake both the motor & drum brake automatically work in tandem.
Tip
Brake Inspection
Please periodically check the brake cable (connection points, wire damage, twisting, etc.) and drum brake (for excessive wear, loosening
of inner wire) to ensure safe and proper braking function.
● At speed, sound may occur from accelerated sections under load (this is torsional vibration), due to vibration from motor
!
and chassis components. At approx. 6~15 mph, this is a common phenomenon of all rotors at specific rotational RPM (eg.
fans, cars, motor boats, etc.), and is not a product defect. However, in event of continuous noise or overly loud metallic noise,
Advisory
supporting bolts may have loosened. Please inspect before use.
● After use, the motor & rear drum brake may produce significants amount of heat, pleaes do not touch!
