Contactless, battery-free bicycle rear light for aluminium rims. Magnic Microlights generate their operating energy while riding without touching the rim. No batteries, spoke magnets or contact dynamo are required.
Please select mounting type and orientation above. With rim brakes, the light is integrated into the brake shoe; the Disc Brake version uses the included flexible strap mount.
Scope of delivery: 1 rear light, 2 rim-protection stickers and mounting tools. Brake shoe and brake pad, or the Disc Brake mount, are included according to the selected version.
Standlight: after stopping, the rear light remains illuminated for several minutes.
Which Magnic Light fits my bike?
Rim brake → Microlights brake shoe · disc brake with narrow/medium fork → Microlights Disc · wide fork/suspension fork/wide tyres → Wega. For Microlights Disc, the outside fork-to-rim distance must be below 65 mm. Wega is universally adjustable for wide forks and suspension forks.

Why Magnic Microlights?
Battery lights need to be charged, while conventional bottle dynamos work with mechanical contact. Magnic Microlights instead use the aluminium rim itself as part of a contactless generator system. A small air gap remains between generator and rim – there is no contact wheel rubbing on the tyre or rim.
Rear-light standlight
While riding, additional energy is stored for the standlight. After stopping, the rear light remains visible for several minutes without requiring a rechargeable battery.
How Contactless Energy Transfer works
A rotating magnetic wheel inside the generator induces eddy currents in the passing metal rim. The resulting electromagnetic interaction drives the generator without direct mechanical contact with the rim. Available light output increases with riding speed.
Compatibility
- Caliper: road and touring bikes with compatible rim brakes
- V-Brake: bicycles with V-Brake rim brakes
- Cantilever: bicycles with compatible cantilever brakes
- Disc Brake: flexible strap mount for suitable forks/frames without using a rim-brake shoe holder
- Rim: an electrically conductive metal rim (aluminium) is required. Conventional full-carbon rims are not suitable.
Designed for long-term use
The generator is fully enclosed and runs on miniature ball bearings. Replaceable brake pads are separated from the generator itself. UHMWPE rim-protection stickers and mounting tools are included.
Frequently asked questions
Does the generator touch the rim?
No. When correctly adjusted, a small air gap remains between the generator and the aluminium rim.
Do I need batteries or do I have to charge the rear light?
No. Electrical energy is generated while riding.
How long does the standlight remain on?
Typically around 4–10 minutes. Duration depends, among other things, on how long the bicycle was ridden beforehand and the operating conditions.
Does the system work in the rain?
Yes. The light and generator are designed for wet-weather use and specified to IPX6.
Can I use Magnic Microlights with carbon rims?
Not with conventional full-carbon rims. The CET principle requires a suitable electrically conductive aluminium section of the rim.
Do Magnic Microlights create resistance?
Yes. Generating electrical power creates a contactless electromagnetic braking torque. Unlike a conventional bottle dynamo, there is no mechanical friction contact between generator and tyre or rim.
