I think this could be a really great way to recycle discarded BMX frames and make nice little commuters that can go on the train or in the trunk of a car.
Also a great way to experiment before going ahead and investing in a smoothound, bianci, or quoroz freedomwon (man I like that bike!)
The major challenge I think is sourcing the super long seat posts and making sure they dont break.
If you have made a mini-velo like this in any config. pls post your picks and share your advice!
I know there was an earlier thread sort of about this, I really think this has potential!
