For families, groups and e-bike tours
Whilst traditional towing systems are often designed for children’s bikes, Sigma takes a much broader approach with the Tow-Up. The towing aid is aimed at families with children, MTB groups, as well as guides and riding technique coaches.
Particularly in this age of high-performance e-MTBs, the problem often arises of people with different fitness levels riding together in a group. Added to this is the risk of misjudging one’s own battery range. This is where the Tow-Up is designed to offer straightforward support.
Help when your strength is waning
The concept is simple: if a climb becomes too steep or you run out of power, the tow assist connects two bikes together. The stronger rider can provide targeted support to the weaker rider without the latter having to dismount or cut the ride short. This is particularly useful with e-bikes. Anyone who has overestimated their range and found themselves facing a long ride home with a flat battery will be familiar with the problem. With the Tow-Up, the rider in question can at least be assisted on easier sections or moderate climbs.
Up to 220 centimetres in length
The Tow-Up’s sturdy nylon rope can be extended to up to 220 centimetres extend. After use, the line retracts automatically back into the compact housing. This eliminates the need for manual winding and ensures the pull aid remains neatly stowed away. The advantage: it’s ready for use in no time, there’s no loose pull cord, and it takes up minimal space on the bike.
Tool-free assembly
Another key feature is its ease of use. Sigma offers a total of three mounting positions: on the stem, on the saddle or on the seat post. It can be fitted without tools and should take just a few seconds. This significantly improves its suitability for everyday use, particularly when switching between bikes or riders.
Lightweight and compact
Weighing just 158 grams The Tow-Up is barely noticeable on the bike. Despite its compact dimensions, Sigma specifies a permissible System weight of up to 120 kilograms to.
This means the pull-assist is suitable not only for children’s bikes, but also for modern mountain bikes, gravel bikes and e-bikes. Sigma recommends a speed of around 10 km/h, making the system particularly suitable for climbs and technical sections.
Part of the RIDE SAFE TO SCHOOL series
Just like the new safety light Nyte Clip CL the Tow-Up is also known as RIDE SAFELY TO SCHOOL-version is available. With this, SIGMA is particularly targeting families who cycle together and wish to offer their children extra support on longer journeys or more challenging climbs.

Conclusion from the editor’s perspective
Bicycle tow systems are now becoming increasingly common across a wide range of cycling disciplines. What was originally developed primarily for children’s mountain bikes is now also being used on gravel adventures, e-bike tours and guided group rides. On long climbs in particular, a tow rope can effectively even out differences in fitness levels. The stronger rider supports the weaker one, and everyone arrives at the end of the ride together. I think it’s a brilliant idea. Stefan Frey, BIKE editor
