By attacking cushion, I can ride with more speed. But that means the power given pedaling is supported by the seat.
In the case of my white bike, I can't give more high power to pedals, because the stealing doesn't have the effection of centering front wheel like python lowracer and it's light for sharing. So the force of seat is enough. It doesn't have to support to the power of pedaling.
I think that the seat of my pink python needs reinforcement.
Up ward is bottom of the seat. I added four pipes for reinforcement.
Two of underside sorry to the power of pedaling. And then upper 2 ones work for reinforcing main frame. The main frame may not be able to support 1000kg. The forcement of carbon steel decreases the force to 35%. I heard that from high skilled man. The other bike maker said the thickness 1.2 mm is also available for my python's frame. The opinion is opposite. Now I don't feel and have any problems about main frame's hardness.

If it works, I can add more power to the pedal.
