Litemove TB03 and TB04: New rear lights with brake light function for road bikes and gravel bikes

Whilst many lighting solutions are put together using components from different manufacturers, Litemove’s ATS-B100, TB03 and TB04 are designed as a comprehensive system for training, commuting and everyday use. The rear lights feature the same design language as the front light and also comply with the requirements of the German Road Traffic Licensing Regulations (StVZO).

TB03: The reliable everyday companion

The TB03 is designed for cyclists who are primarily looking for a reliable rear light that requires as little effort as possible to operate. The light produces up to 20 lumens, has two constant-on settings and uses a memory function to save the last setting used.

With up to 11.5 hours’ battery life in standard mode, its endurance makes it ideal for everyday use. It is charged via a permanently integrated USB-C cable. This eliminates the need for additional charging cables and makes the rear light particularly practical for commuters.

The mount also appears to be well thought out. A magnetic quick-release fastener ensures that the light can be removed for charging in a matter of seconds.

TB04 with intelligent brake light function

If you’re looking for a bit more technology, the TB04 is the one for you. At first glance, it looks very similar to the TB03, but the differences lie inside.

The TB04 also features a braking warning function. If the built-in sensors detect deceleration, the rear light briefly increases its brightness to up to 90 lumens or 40,000 mcd. This is intended to alert following road users to braking manoeuvres at an earlier stage.

In addition, Litemove incorporates emergency braking and warning functions designed to provide additional safety benefits, particularly in urban traffic or on busy cycle paths.

The battery life is up to 10.5 hours in standard mode. Otherwise, the TB03 and TB04 share the same platform, with identical dimensions, weight and magnetic mount.

Ideal for aero seatposts on modern road bikes

What’s interesting is their high level of compatibility with modern road bikes. Many of today’s aero bikes use heavily profiled seatposts, to which traditional rear lights are often difficult to attach. According to the manufacturer, the TB03 and TB04 fit both round and aero seatposts with diameters between 22.2 and 35 millimetres. This makes them suitable not only for gravel bikes and everyday bikes, but also for modern road bikes with integrated aero designs. The compact design is also intended to ensure that the rear lights blend discreetly into the bike’s overall appearance.

Thanks to their IP56 certification, both models also offer sufficient protection against rain and dust, ensuring they can be used all year round in everyday life.

The design is consistently geared towards everyday practicality. With an integrated USB-C cable, magnetic mounting and long battery life, these two rear lights are more than just run-of-the-mill products.
