Litemove ATS-B100: Compact rechargeable light with clever Aero mounting system

Gravel bikes and endurance road bikes have long since ceased to be used solely for sporting rides. Many cyclists use them to commute to work, go for training rides at dusk or set off on longer tours through autumn and winter. Consequently, the demands placed on lighting are increasing. With the ATS-B100, Litemove presents a compact rechargeable light designed to bridge the gap between sporting use and everyday life.

Flexible mounting for modern cockpits

Weighing in at 203 grams, the ATS-B100 is not exactly a lightweight in its class. However, the torch features a comparatively large 5,000 mAh battery integrated directly into the casing.

The mounting system is particularly interesting. The light features a tool-free quick-release mechanism and can be used with both Garmin and GoPro mounts. This means it is compatible with modern cycle computer mounts as well as traditional handlebar mounts.

Advantage for aero handlebars and integrated cockpits

Fitting lights can often be a challenge, particularly on modern road bikes with aero handlebars or fully integrated cockpits. Traditional round handlebar surfaces are often no longer available, whilst cycle computer mounts and cable integration take up additional space. The ATS-B100 offers a particularly elegant solution to this problem: thanks to the guide groove on all four sides of the housing, it can be mounted both above and below the handlebars or a front computer mount. This ensures a tidy appearance, improves integration into the cockpit and enables the use of high-performance lights even on modern aero road bikes without the need for additional adaptor solutions.

Up to 100 lux light output

According to the manufacturer, the lamp delivers 100 lux or 700 lumens in its highest setting. These are impressive figures for a compact rechargeable torch. Litemove states that the beam range is up to 200 metres. At the same time, the so-called ATIR optics are said to produce an even light pattern 8.5 metres wide.

Even more important for use on public roads is the clearly defined light-dark boundary. This prevents oncoming road users from being dazzled and is a prerequisite for approval under the StVZO.

Automatic light adjustment in everyday life

One feature stands out in particular: the built-in ambient light sensor. The ATS-B100 automatically detects changing light conditions and adjusts the brightness accordingly. Anyone cycling through well-lit city centres in the morning and then switching to dark cycle paths later on doesn’t need to keep switching between different brightness levels.

For commuters and frequent cyclists, this is likely to be one of the biggest advantages. In day-to-day use in particular, ease of use often counts for more than maximum light output. The integrated memory function also allows you to quickly reactivate the last mode used.

Also suitable for long journeys

With a maximum running time of up to 15 hours, the ATS-B100 is also suitable for longer periods of use. According to the manufacturer, it can run for up to 1.5 hours in the highest power mode, and significantly longer in Eco mode.

Charging is via USB-C. The light also supports charging via a power bank whilst in use. This should be of particular interest to bike packers, long-distance commuters and cyclists who do not want to be without sufficient light, even on training rides or brevets lasting several hours.

TOUR SUMMARY

The Litemove ATS-B100 is a well-designed lighting solution for road, gravel and commuter cyclists. Its versatile mounting options on modern aero handlebars, in particular, set it apart from many of its competitors. The automatic light sensor and the option to power the light on the go using a power bank also make it well-suited to long training rides, commuting routes and bikepacking adventures. Whether the light distribution can hold its own in practice against established premium brands such as Lupine or Supernova remains to be seen in a detailed practical test.

How important is automatic light control to you when it comes to road bike or gravel bike lights? Do you prefer to use an automatic mode, or do you adjust the brightness yourself?
