Top product, top quality The first 150 kilometres have been completed, time for a short summary. Delivered in a large cardboard box, the Speed Racer S comes partially assembled. Assembly is child's play and can be done without further help and with the tools supplied, even if a second person would be helpful at one point or another. Once assembled, the Speed Racer S makes a very stable and high-quality impression, a feeling that was confirmed on the first 150 kilometres. Once adjusted and tightened, nothing wobbles and there are no annoying noises, so I am very happy with my new training device. Unfortunately, I can't comment on the training programmes as I've been using the Kinomap app since day one. One more sentence on this. Kinomap harmonises with the Hammer Speed Racer S without any problems, and the Speed Racer S is recognised directly by the app and connected to it within a few seconds. This makes training fun.
