Finally, the device also automatically detects nightfall, at which point it turns on a front-mounted headlamp. And when you stop the bike and dismount, the light turns itself off. With all that lighting up, it might seem like you’d need to recharge the device daily, but the creators of the SmartHalo claim that its battery will last up to three weeks.
SmartHalo, which will retail for $149, is available for $99 for early adopters via a Kickstarter campaign that has already reached $39,000 of its $50,000 goal. If you sign up to smarten your bike up, the makers promise to get the device to you by May of 2016.
