Suspension springs that are soft at the beginning and firm at the back, with a focus on safety performance.
The tire follows the road surface flexibly, and the ground contact force of the tire is improved by the repulsive force of the spring.
It is not too soft and not too hard to reduce the fatigue of riding for a long time.
●The change of the caster during braking before a corner is optimized to make it easier to move on to the next action.It absorbs small gaps during cornering and eliminates vibrations that interfere with the rider.
●Unlike normal springs, there is no resonance because there is no constant spring rate.
●Springs wound by computer-controlled machine tools are subjected to a shot treatment to remove microscopic surface flaws that can degrade performance.In addition, after the completion, the performance of each unit is inspected by a tester.
●In the Netherlands, the home of Hyperpro, all emergency bikes are fitted with Hyperpro springs.
