Lezyne KTV Pro Ai Alert StVZO Rechargeable Rear Light

Compact, unobtrusive and smart: The KTV Pro Ai Alert StVZO rechargeable rear light from Lezyne is designed for bike commuters and leisure riders who want to take their visibility in road traffic to the next level. 

The rear light features Ai-Alert technology, which recognises deceleration while riding and automatically increases the light intensity when braking. This will alert following road users to the fact that you are slowing down. The integrated 400 mAh battery is charged via a permanently installed USB-A plug; a separate charging cable is not required.

Thanks to its compact design, the rear light can be mounted on round and aerodynamic seat posts.
