Bicycle, the world’s favorite means of transport, is eco-friendly and economic too. But, many don’t use it for some inconveniences it has, besides its unstable center of gravity – though the chain drive is highly-efficient, its being exposed just beside the pedals makes it dangerous as it cuts skin, destroys garments by tearing it or spoiling it with grease.
Here is a wonderful solution to this. How would it be to have a bicycle without a chain? That is exactly what the US-based Dynacraft has introduced, though a bike with a similar drive mechanism was built in 1899.
Named Dekra-D Drive bike, it has an internal drive shaft offering less maintenance, greater safety and a cleaner solution compared to a conventional chain-driven bike. It replaces the most problematic bike parts that also require the most maintenance, i.e. the chain and derailleur. Buy it to have an eco-friendly and safe journey.
