We are manufacture of hiwheel bike and we have been developed a hub which is very becomming for hiwheel bike and we create the modern bike which is more in safety and dynamic. In case of the existing Penny farthing, it's all-in-one system. so no one put his poot on the pedal in a very fast running or a downhill road and finally it can encounter dangerous situation. we corrected such kind of faulty and make it with embedded driving and braking part in an inside of hub. so we realized safety pedal function and created clean design in view.
