The current 250W Legislation states that electric bikes must be speed limited to 25 kph under pedal assist mode and 6 kph under twist throttle mode. If you plan on riding your ASEAKO electric bike off road, then you will be able to disable the speed limiter which will then allow you to reach speeds of approx 32kmh with a small amount of assistance from the rider in pedal assist mode.
Range of 45 – 60km is the expected range, depending on terrain. This is based on using “Medium” power assist mode. If a lower level of “power assist” is used then your riding range can increase significantly.

Your bicycle will come with a 240V “Smart Charger” which allows you to charge you battery while it is either attached to the bike, or you can remove your battery and charge it anywhere you like. Once the charge light turns from red to green, your battery is fully charged. Once the green fully charged light comes on, your charger will stop charging your battery.
Pedelec System Engages the motor when the rider starts to pedal, the motor stops assisting when the rider stops pedaling, or when the brakes are applied. There are 5 levels of power assistance managed via our Smart LCD control panel with power and distance management – speed, trip distance.
The Twist Throttle is located on the left hand grip. This allows you to keep your feet stationary and just ride using the twist throttle. Please note that 250W speed restrictions apply for throttle control, as per the information above under the “SPEED” heading.
