## Description

desertcart.com : BikeSpark Auto-Sensing Rear Light BKS-G5, Precise Brake Sensing for Bike Cargo Rack, AirTag Mount, Type-C Rechargeable, Large Reflector, 50/80mm Bolt Spacing Mounting, Made in Taiwan : Sports & Outdoors

Review: Great light many options - Great light nice and bright, I like the fact it just turns on and off on its own. My only concern if you dont have a open slot to mount on bike rack it gets interesting mounting on existing fenders, The mount holes line up but you cant bend to the curve of fender (longer screws resolves this for the most part)
Review: Nice taillight with the added bonus of a brake light! - I installed one of these on my bike prior to a week trip at the coast. I also talked a friend into getting one as well. He was bummed at first as he said that it didn't turn off for putting on a rack as other reviewers had also mentioned. I showed him the 5 position button that ultimately turns off the light for traveling. So we both had these lights on our bikes and went for a few rides and we were impressed how quickly the brake light reacts to braking or even slowing down. The auto shutoff is great for short stops at restaurants or stores as you don't get halfway down the street and realize that you forgot to turn on your taillight. The only time that I turn mine off now is just prior to putting the bike back on the rack for the drive home. Excellent light!

## Features

- BikeSpark’s Auto-Sensing Rear Lights detect bike deceleration with an innovative deceleration sensing algorithm, Vsenx (US Patent No.: 10427594 B2). Once deceleration is detected, BikeSpark increases the brightness to ultra-bright for 2.5 seconds, alerting and improving the reaction time of the person in any vehicle traveling behind.
- Automatic ON/OFF - Press the Control Button to turn on the light and you are good to go. Never have to remember to turn off your rear light again! BikeSpark turns off automatically after 1 minute of inactivity, and turns on when motion is detected. The perfect balance of convenience, battery life and riding safety.
- Great Brightness meeting Regulatory Compliance - Super bright LEDs provide excellent long distance and 220 degree visibility. Four lighting modes accommodate various cycling conditions. Besides, two constantly-on lighting modes that comply with Germany StVZO Regulations help you riding safely in the darkest nights.
- Highly Reflective Reflector Meeting Regulatory Compliance - BikeSpark BKS-G5 equips with the world-class vehicle reflector. The highly reflective reflector is compliant with German StVZO standard.
- Type-C rechargeable - The light comes with a built-in 550mAh li-polymer battery and is rechargeable with the type-C port. Quickly and conveniently get the light fully recharged before cycling.
- AirTag Mounting Compatible - Turn the bike light to a tracking device without extra cost. The compartment at the back of the light unit allows you to mount AirTag on the light. No tools required and simply press to click the AirTag in place. Easy and convenient to track or locate the bike or the light unit. AirTag is not included.

### ⭐⭐⭐⭐ Decent for price
*by L***N on December 5, 2024*

Hello there! I’m an e-bike owner. I bought this rear tail light for my e-bike, it’s a Vivi ACE01 E-bike. This is the only light I could find with reasonable ratings and a reasonable price. For those that own a Vivi ACE01 or have the exact same reflector tail light, then this light is compatible for your bike. The box came packaged correctly and was well sealed. I took it out, charged it and set it up. It’s easy to setup and install, if you’re curious, no, it does NOT come with an AirTag, you got to buy that separately or from Apple. So once it’s installed, you’ll see a big hole where the Apple tag goes. For functionality, the button isn’t a soft push button, it’s hard to push. You have to give it minimal force, slightly, just to turn it on or switch modes. The brightness, it’s DECENT. But not BRIGHT enough. If you want something BRIGHT, then I wouldn’t recommend this product for that. I’d say this light is just enough for people to see you maybe 200 feet away and that’s it. Stability is perfect, no issues with it. California roads are insanely bad, so it works just fine, 0 issues. I’ll be back next month to update my review on everything such as battery life, durability, etc. Thank you for taking the time to review my review.
