RooDol is a three roller training system without any sort of fix holder for the bike in order to produce a sensation as realistic as cycling on the road. For that reason, you have the implicit possibilities of falling off when cycling a bike. Though, when cycling of your RooDol the possibilities of falling off are a little less than cycling on the road just because you won’t have to deal with any variation on the ground. Despite this all, we strongly recommend you to keep you focused on your cycling when using RooDol bearing in mind that this training system does not include any holder to your bike.
