Who should buy it
The Koolux X2 is for budget-conscious riders who want a big battery. It is also for riders who do not need to lift their bike often. If you park on the street or in a garage, the weight matters less.
- You want a long estimated range of 51 km without paying extra.
- You ride mostly flat city streets and do not need high torque.
- You have a place to store a heavy bike at ground level.
Look elsewhere if you need a light bike or a throttle. Also look elsewhere if you want a step-through frame. The X2 has none of those features. It is a simple, heavy, affordable city bike.
