Mechanical Engineering Tech Student
Hi my name is Lee and I am a Student in Edmonton Alberta, Canada
I am currently working on a final project for my program and am wondering if i could get some help from the people in this comminuty.
I am designing an add-on for a Wheelchair which involes using a bicycle shaft drive and internal gear hub for a person to pedal with their arms to move around. I understand the basics of how the bicycle shaft drive works but google doesnt help for more advanced questions.
I need to know if a shaft drive system can be used to move backwards?
What the cheapest internal gear hub that is modified to work with a shaft drive system? so far I could only find shimano alfine but it is out of the design price criteria.
And I am most likely going to design my own shaft as the length needs to be increased. But i need to know who makes the cheapest shaft as well?
If anyone who sees this knows anything about this or can point me to someone who can I will be forever grateful. :)
