Lezyne Saddle Ai Alert 250 Rear Black, One Size

"What Our Gearhead® Experts Are Saying:""The Saddle Ai Alert 250 Rear is the most complete rear light I have run. The Ai Alert brake detection kicks in instantly every time I slow down and the 250 lumen Active Alert flash is impossible to miss from behind. Combined with the saddle mount position and 270 degree Wide Angle Optics, it covers every angle traffic could approach from and communicates both presence and intent without me doing anything beyond riding.""Presence and intent are two different things, and most taillights only communicate one of them. The Lezyne Saddle Ai Alert 250 Rear handles both. Mounted at saddle height where following traffic sees it most clearly, it pairs the positional advantage of a saddle mount with Ai Alert brake sensing technology that automatically detects deceleration and shifts into Active Alert mode, triggering a 250 lumen flash that signals stopping intent to drivers and cyclists behind with the immediacy of a dedicated brake light. The system is pre-programmed, requires no setup, and collects no rider data. Ten super-bright LEDs work through Wide Angle Optics to deliver 270 degrees of visibility, ensuring the light registers to traffic approaching from behind and from oblique angles equally. Seven combined solid and flash output modes span from the 250 lumen Day Flash for maximum daytime conspicuity down to the 60 hour Femto mode for extended runtime through weeks of regular riding. Fully CNC machined aluminum construction in satin black brings material quality and heat management to the rear light category, and IPX7 waterproofing handles any weather without concern. The twist-off light body separates from the saddle mounted base for USB-C charging without removing the mount from the bike."
