Because he was meant to be Shocker’s greatest altered human, Kamen Rider's capabilities are far greater than a normal man. He has the ability to hear at distances up to 4 kilometers away. He can break a meter thick tree trunk or a metal rod 10 cm thick with his Rider Chop. His Rider Kick has enough power to bend steel supports of buildings. Even when he wasn't fully transformed, this form was strong enough to withstand a 50,000 volt electric shock.
Unlike in his later forms, Hongo can't transform automatically in this form, needing external wind to jump start the Typhoon's turbine and give him access to his suit and most of his fighting strength. That wind is generally generated by riding his bike, but it also can come from other sources, like an explosion that pushes hot wind towards the Typhoon belt. It is thinkable that becoming Kamen Rider has granted him a degree of immortality and immunity to organic diseases, viruses, bacteria and poison due to becoming a cybernetic human.
