BikeSpark Taillights Editorial Review

The BikeSpark Auto-Sensing Rear Light G4R is a USB rechargeable light with a 240HR battery life, precise brake sensing feature, and large reflector. The light is designed to mount on the bike's cargo rack with a 50/80 mm spacing, and the package includes a screw mounted easy release. However, customers who do not have a standard rack must drill holes to mount the light. Some customers have noticed that the mounting bracket is not very secure, and the light popped out while riding over sidewalk bumps. Despite this, the light features unique characteristics like auto shut off and turn on with changes in motion, a strobe light that gets drivers' attention without blinding them, and brightness that is good even in daylight. The product's auto-sensing feature is not light-sensitive, and the light turns on and off alternatively based on motion. The mounting latch is not very secure, and the bracket is not available for sale separately from the light. Some customers do not recommend purchasing the light due to its mounting issues. However, other customers are pleased with the product and say they can easily set and forget it. The battery life of the light is good, and it accomplishes what it is advertised to do. In summary, the BikeSpark Auto-Sensing Rear Light G4R is a good product to Consider if you are looking for a light with a precise brake sensing feature, unique features such as auto shut off and turn on with motion changes, and brightness even in daylight.
