Recumbent Lowracer driving and stearing with Front wheel

This is first prot type recumbent lowracer of this type.

 The recutangular frame is used mainly. Because it's easy to weld them. almostly the jig doesn't be needed.
I designed this for DIY. I'm thinking to sell the technical drawing.
I blog my making stuff in this blog. They will become manual for DIY.

If you'd like to get completed frame, the frame will be made in the Prison.
The prisoner's welding skill is enough to make frame, I think.

Unfortunately, I don't like writing any things in japanese language. The language is heavy for my brain, Although it's my mother language.

Reinforcement

The seat of pink python isn't hard enough.
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.

Making cushion for seat

I think some cushion is needed for recumbent lowercase to ride in the town.
So I made it.
At first, two Velcro strap were made.

Then, a piece of cloth was prepared to cover cushion.





The two Velcro belts were attached the cloth.


Next, a fastener were attached and sewed around.



I cut cushion and pushed in the cover. Then it was attached the seat.

Then, checked total balance.


From now, I go out by this bike and I check the cushion.
