Why Grenda is your best choose? 1:This bicycle is a land vehicle propelled by muscle power of the legs,it,during its motion,is subject to different forces,which depend on conditions and are opposite to the motion. 2:Stiffness prevents the loss of the energy generated by the rider from useless deformation of the frame,and transfer it to the rear wheel. 3:We allowed every rider to get on board the new bike and experience the improvement. 4:To reduce the energy needed in a hilly route or climbs,furthermore,this would also reduce the bike's inertia. 5:We also increase powertrain stiffness and vertical compliance.
