Based on our Aseako Alto & Aventi models, we have upgraded the power and management system with our unique 250W / 500W mode selection that allows you to select 250W On-road mode at which time all power and speed limitations are engaged in accordance with on road usage regulations. Alternatively, when off-road you can select 500W mode to get the extra power you need.

Note: While in on road (250W) mode, the bike technically meets all current legal on-road regulations, however in some jurisdictions it may be deemed not to. In 500W off-road mode, the bike does not meet legal on-road regulations. You should make yourself aware of your states regulations.
In addition, we are now using the NuVinci 380 Continuously Variable Tramsmission (Find out more at NuVinci) which provides a superior gear management system and creates a simpler and smoother riding experience.

The Aseako Ultra II has two (2) systems for applying power depending on what mode you are operating in:
- In On-Road 250W mode you have one (1) power application system being the standard Pedal Assist function.
The Pedal assist system engages the motor when the rider starts to pedal and continue assisting until the rider stops pedaling, applies the brakes (safety feature) or the legal max 25 kmph assist speed limit is reached.
There are 5 levels of power assistance accessed via a handlebar selection button and a LCD management panel.
- In OFF-Road 500W mode, you have both pedal assist function and a Twist Throttle function available.
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. You need to be aware that operating the bike in this manner will use more power and decrease you battery range and once again in this mode the bike is NOT legal to operate on public roads and pathways. Also once again, when in 250W on-road mode, this throttle control function is NOT available.
The travel distance on one 10Ah battery charge can be up to 60 or more km per charge however this is under optimum riding conditions and using good rider management – i.e. efficient use of power levels, gears and reasonable rider input. On average we find a more realistic expectation is around 30 – 40km depending on terrain, rider size, rider input level and weather conditions such as wind and rain. This is based on using “Medium / High” power assist mode most of the time. If a lower level of “power assist” is used then your battery range can increase.
In terms of speed, as noted above current legislation states that electric bikes must be limited to 250W power output and have a maximum speed of 25kph under pedal assist mode and 6kph under twist throttle mode to be able to ride on roads or public pathways.
If you plan on riding your ASEAKO bike off road, then you can switch to ‘off-road’ mode which will disengage these limits and allow you to reach a speed of approx 38-42kmh with a minimal amount of assistance from the rider using the pedal assist system.
Again as noted above, it is not legal to ride the bike on public roads and pathways in this mode. Check your local regulations for clarification.
