VanMoof have taken integration, security and connectivity to the next level with the S3 and X3. The frame houses a 504Wh battery and integrated LED lights. So strong is VanMoof’s commitment to integration that the battery is not actually removable and for most people, charging the bike is likely to involve carrying it into their house or workplace (or anywhere that’s near a charging point). The 250W motor is built into the front-hub while the rear-hub contains a 4-speed electronic gearing system that detects the bikes speed and torque and shifts automatically. The rear wheel can be locked when parked, rendering the bike immovable and setting an in-built alarm that literally barks at any potential bike thieves. This security function works in conjunction with the VanMoof app on your phone to help you track exactly where the bike is at all times. The slick handlebars are equipped with two buttons - the left is an electronic bell which can be selected through the app, the right is perhaps the bikes most fun feature: the turbo. This button provides electronically assisted overdrive to help you safely pull away from traffic or carry you up a steep hill. These features combined with an elegant geometric design make this smart and stylish e-bike one of the very best (and enormously fun) urban electric bikes available on the market right now.
