Technology Packed Into Every Model

Alter Ego Electric Bikes are packed with technology. We have collaborated with engineers from all over the world to bring you the best riding experience you will find anywhere.

The Best. Period. 



ipas - intelligent pedal assist system

Our selectable multi-speed iPAS system detects your pedal cadence and adds motor power up to your desired level of assist. There is no need to control a throttle, all electronics function at the push of a button. Riders can simply pedal, concentrate, and enjoy the ride while sensing the motor performance.

iboost throttle drive system

All ALTER EGO Electric Bikes come equipped with our easy to use throttle to dial in the power output of the motor. Use it while you pedal, or don’t pedal at all, the instant response of turning the throttle lets you control the speed. Battery range is reduced by approx. 50% with throttle only use, so for maximum range we advise you to pedal and let the iPAS do the work for you. This is a similar experience to a motorcycle. 



An intelligent battery management system (iBMS) is an electronic system that manages a rechargeable battery (cell or battery pack), such as by protecting the battery from operating outside its Safe Operating Area, monitoring its state, calculating secondary data, reporting that data, controlling its environment, authenticating it and / or balancing it.

A battery pack built together with a battery management system with an external communication data bus is a smart battery pack. A smart battery pack must be charged by a smart battery charger.

Our batteries utilize advanced lithium-ion chemistry with on-board battery management system (BMS) for superior performance and charging. Together these lightweight, high capacity battery packs, BMS and chargers ensure a long lasting and reliable source of power. Our batteries can be charged while on the bike, in the house, at the office, or even the coffee shop. It can also be locked so it can not be stolen.

ifold 3 step folding SYSTEM

Our Ultrabikes fold down smoothly in seconds with just 3 easy steps. This makes it incredibly portable so you can bring your Ultrabike anywhere you go! 

Our #1 priority is to provide a top quality product, and uncompromised riding experience. All of our models will give you the ride you'd expect and the bonus of being able to fold it for ultimate experience. This sets us apart from the rest of the 'foldable bike' market.


We use Samsung and Panasonic lithium cells to give you the longest battery life, best warranty, and longest range on a single charge. Our batteries have smart circuitry, which means you will never over charge your battery and you don't have to wait until it is completely dead before charging. 

Some of our models have a hidden in-frame battery that streamlines the design of the bike. They can be removed and changed with ease and can be charged on or off the bike.
