Stay Safe With Added Breathability

As Stan Lee knows all too well, with great power must come great responsibility. This is also true when it comes to your favorite electric bike. The Serfas® Kilowatt is E-Bike certified. Keeping you safe in the unfortunate event of a fall. This ultra-secure helmet is durable yet doesn't restrict breathability. Eight adjustable vents can slide open or stay closed, which allows for some much-needed airflow while out on the ride of a lifetime.

The Sefras® Kilowatt E-Bike Helmet features a bright built-in rear LED safety light for added visibility. Complete with additional rear-facing reflective design accents, you can ride in low-light conditions with no second thoughts. An easy-to-adjust fit system uses a rear knob for added comfort, keeping any painful pinching to a minimum. Weighing in at only 484 grams, this ultra-secure helmet keeps you safe without dragging you down.
