The bicycle is an old, easy and healthy way to move from one place to another. You don’t have to recharge it or get special driver’s license to drive it. If you ride a bike for a long time sometimes it can be interesting to know more about your riding: what the speed is or what pulse do you have now. SmartHalo 2 can help you with all this things and also it has 250 lumen front light and navigation system. The device also has alarm mode with a 110dB sound (as loud as a sound of helicopter nearby).
