Handbikes trigger feelings of happiness, which is why sometimes it is not so easy to stay on the ground and not take off. To ensure that the traction is not lost, additional weights with a strap and a KLICKfix holder, which are attached to the front wheel, are an important component. If the terrain is uneven and doesn't have a good grip or if it is too steep uphill, it is possible that too much weight is placed on the wheelchair wheels and there is a risk of tipping. Exactly such hazards are avoided by additional weights. When accelerating, the tyre doesn't spin and you are safer on the road, because the wheel maintains better contact with the ground even when the braking distance is reduced.
