Dynamics is the house brand of the direct supplier Zweirad Stadler, which emerged from a bicycle shop founded in Regensburg in 1936. The family-run business currently operates 22 of its own specialist bicycle stores in Germany and Austria. Stadler stocks selected specialist retail brands, but also has its own, particularly favourably priced bicycle models manufactured under the Dynamics brand by proven suppliers such as the ZEG purchasing association.
The affordable bike in practice
The elegant Dynamics Magic Eight has a contemporary aluminium frame with a high-quality finish. The straight aluminium fork ensures agile steering. Wheels with voluminous 47-millimetre tyres, Nexus gear hub and the chain protected on all sides by the Hebie chain slider stand for low maintenance and long-term trouble-free operation. We liked the carefully designed chain tensioning mechanism: the rear wheel axle can be infinitely adjusted by 20 millimetres and precisely aligned using two grub screws. The slightly raised saddle and long top tube create a sporty, stretched riding position which, together with the smooth-shifting eight-speed hub and the sensitive, powerful disc brakes, enables a fast, safe riding style. The frame and fork are torsion-resistant and the bike reacts well to load changes and luggage. Even our full test load of 22 kilos in two panniers did not upset the pannier rack and bike.
At just under 16 kilos, the Dynamics Magic Eight is within an acceptable weight range and is not too heavy to carry up or down stairs. The gear ratio and gear steps of the Shimano Nexus hub are sufficient for most riding situations. However, steep or long climbs and sporty sprints are not its thing. The chain glides on low-wear plastic in the fully enclosed chain guard of the Hebie Chainglider. It can rattle a little on rough roads, but the advantages outweigh the disadvantages: The chain is protected from dirt and moisture and lubricated in advance. It needs to be cleaned less often, requires less maintenance and lasts longer. Due to the low price, the simple crank with pressed-on steel chainring stands out. It has to be completely replaced when worn and does not offer the smooth running and efficiency of a high-quality branded crank.
The Dynamics Magic Eight in detail
At 6.5 kilos in total, the heavy wheels account for more than a third of the total weight. As a result, the Dynamics Magic Eight is rather sluggish when setting off, and the rotating mass also requires a firm grip when steering. The headlight shines acceptably bright, but with a patchy light field. The only attached ergo grips rotate when gripped firmly, but can easily be replaced with screw-on grips. As both wheels run on solid axles, as is usually the case in this test field, you'll need a 15 mm open-end or ring spanner to remove them in the event of a puncture or during transport - even on the move. The Magic Eight is perfect for everyday use, but can also take a trip or a multi-day ride with luggage without complaint, as long as there are no steep climbs to contend with.
