The Reelight GO E Bike Light is a self-powered bicycle lighting system that uses electromagnetic induction for energy-efficient illumination. Unlike traditional battery-dependent lights, it harnesses wheel rotation to generate power, offering eco-friendly visibility. Key features include automatic activation, no wiring, and compatibility with most bikes. Its patented design ensures reliability in urban commuting and low-light conditions.
How Electric Dirt Bikes Are Transforming Off-Road Riding
How Does the Reelight GO E Bike Light Work?
The system uses magnets mounted on wheel spokes and a generator unit attached to the fork. As wheels spin, magnets pass the generator, creating electrical current through electromagnetic induction. This powers LED lights without batteries or charging. Activation occurs automatically at speeds above 3 km/h, with brightness adjusting to riding speed.
What Are the Installation Requirements?
Installation requires 15 minutes using basic tools. The kit includes spoke magnets, generator units, and mounting hardware. Compatible with 20″-29″ wheels and 9-13mm axle diameters. Requires stainless steel spokes for magnetic adhesion. Not suitable for carbon fiber wheels or fat bikes exceeding 4.8″ tire width.
Which Safety Certifications Does It Hold?
Reelight GO meets ISO 6742-2 cycle lighting standards and CE directives. The LEDs produce 10-lumen front light and 5-lumen rear light, exceeding EU minimum requirements. Strobe mode enhances daytime visibility. IP54 rating protects against dust and water spray.
How Does It Compare to Battery-Powered Alternatives?
Unlike battery lights needing frequent charging, Reelight GO provides unlimited runtime. However, maximum brightness (10 lumens) is lower than premium USB-rechargeable models (100+ lumens). Ideal for urban riders prioritizing convenience over extreme brightness. Eliminates “dead battery” scenarios but requires minimum speed for activation.
When evaluating lighting options, cyclists must consider their primary usage. The Reelight GO’s 10-lumen output suffices for city environments where streetlights provide ambient illumination, while high-power battery lights become crucial for unlit paths or nighttime trail riding. A cost analysis reveals long-term savings: while premium USB lights cost $50-$120 upfront, Reelight’s $89 kit requires no ongoing battery expenses. Environmental impact differs significantly too – the induction system avoids 18-24 disposable batteries annually per commuter.
| Feature | Reelight GO | Battery-Powered |
|---|---|---|
| Brightness | 10 lumens | 50-1000 lumens |
| Runtime | Unlimited | 2-12 hours |
| Maintenance | Annual check | Weekly charging |
Urban commuters favoring sustainability often prioritize Reelight’s “set and forget” operation, though mountain bikers may still require supplemental lighting for technical descents.
What Maintenance Does the System Require?
Annual maintenance includes cleaning magnet surfaces and checking generator alignment. No component lubrication needed. LED lifespan exceeds 50,000 hours. Spoke magnets may require re-tightening after 500km. Generator units withstand 100,000+ wheel rotations.
Regular maintenance ensures optimal performance. Cyclists should inspect the generator unit’s air gap (1-3mm from spokes) monthly using the included spacer tool. Magnet surfaces accumulate iron particles in wet climates – clean bi-annually with isopropyl alcohol. For high-mileage users (300+ km/week), consider replacing nylon magnet mounts every 18 months due to UV degradation.
| Component | Maintenance Task | Frequency |
|---|---|---|
| Magnets | Surface cleaning | Every 6 months |
| Generator | Alignment check | Annual |
| Mounts | UV inspection | Every 18 months |
Dealers report 92% of units function flawlessly for 5+ years with basic care, outperforming many electronic bike components in longevity.
Can It Be Used With Electric Bikes?
Yes, compatible with Class 1-3 e-bikes. The electromagnetic system doesn’t interfere with motor operations. Speed sensors maintain functionality up to 45 km/h. Ideal for pedal-assist models where consistent lighting supports varied speed ranges.
“Reelight’s induction technology addresses the critical pain point of battery management in bike lighting. While not suitable for pitch-black trail riding, it’s revolutionized urban cycling infrastructure projects. Copenhagen’s city bikes adopted similar systems, reducing maintenance costs by 40%.”

Conclusion
The Reelight GO E Bike Light offers a sustainable lighting solution for daily commuters. Its maintenance-free operation and automatic activation make it ideal for riders prioritizing convenience and eco-friendliness over high-intensity illumination. While not replacing high-power trail lights, it fills a unique niche in urban mobility ecosystems.
FAQs
- Does Reelight GO work in complete darkness?
- Yes, but with reduced visibility compared to high-lumen lights. Recommended for street-lit urban areas rather than unlit rural roads.
- How weather-resistant is the system?
- The IP54 rating withstands rain and snow but isn’t submersible. Avoid high-pressure washes directly on components.
- Can I install multiple front lights?
- Yes, the system supports daisy-chaining up to 3 additional lights using Reelight’s extension kit (sold separately).
