First post here but I think you all will like the project I am starting.

I have a Vroom electric bike that I want to adapt for my SO to use. Because of a recently developed permanent nerve issue the motion of leaning forward and sweeping a leg over the seat isn't an option so I want to make this a step through frame. Basically I want to remove the cross bar and move it as low as possible then add reinforcing tubes where needed. I added pictures of the frame and what I plan to change to my gallery but can't post links to the picture until I have made 10 posts myself. I would rather not just post smileys on a bunch of posts to get the count so I will post this and hope for the best.

My initial thoughts on how I would modify the frame would be to remove the red tubes and add in the yellow. I think I would use 1.5" C channel that would be welded directly to the remaining tubes.

Would the planned additions give the strength needed? What changes would you make?

Should also add that appearance isn't at all a priority getting something functional for as low cost as possible in most important.

Thanks for the help!
