Description
The Aseako Xtreme 250W / 500W Dual mode Electric Bike is the second in our range that features our latest unique e-bike development. Based on our Aseako Tourney & Rossa II models, we have upgraded the power and management system with our exclusive e-smart 250W / 500W mode selection system 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.
Other standard features of the Aseako Xtreme II include:
- Smart LCD control panel with power and distance management – speed, trip distance.
- Twist throttle power control along with standard pedal assist function
- Samsung 48V 10aH battery
- NuVinci 380 continuously variable transmission. (See NuVinci for more detail)
- RockShox front suspension forks with adjustment and lockout
- Tektro disc brakes front and back with electric motor cut-off function for additional safety
- Velo Air seat – wide and extremely comfortable making for a great ride
- Our unique mid-drive motor/reducer combination that works with the gears to provide superior hill climbing ability and better battery performance
- Semi swept back handlebar with adjustable neck to provide a more upright riding position for those who prefer that or otherwise simply adjust it back down.
- Integrated front and rear lighting
- Built in rear rack suitable for attaching pannier bags or baskets to carry those extra items.
The Aseako Xtreme II represents great value for an easy to ride crossover e-bike suitable in both on-road and off-road situations and able to handle the toughest hills.
The Aseako Xtreme 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.

I have had my zoco xtreme 2 for a few weeks now, and I could not be happier. This bike is all quality, the only drawback is the battery position prevents the seat from being fully lowered. If the battery was positioned 50mm further back it would be perfect. Apart from that, if you want an electric bike you will not be disappointed with a ZOCO. I have had many positive comments about this bike from other very jealous E-bike owners.

Have had my Zoco Xtreme over 12 months and have enjoyed some quite extreme off road rides (Kinkin to Lake MacDonald to Pomona,Brisbane Valley rail trail)as well as many of the local bike tracks,and the bike has performed perfectly .The after sale service has been exceptional,carried out by Darren the local agent.All in all a great all round bike.

This bike is fantastic and is the best bike I ever owned. I had for two weeks now and I enjoy it every moment. Easy to assemble. The suspension is absolutely amazing. What a ride. The Nuvinci gearing is out of this world. I can’t believe in this modern day and age folks still use multi sprocket systems.

Bought the xtreme 2 about a month ago and couldn’t be happier. Easy to use and find I’m using it in preference to the car. Brett is great to deal with. Highly recommended.
