The brake lever on my older flip n go was no longer available. It was the red lever style on the front right wheel.
I bought this brake lever and a 60" cable. I had to drill holes in the top frame to mount the lever and had to trim the cable housing with an angle grinder zip disk ( probably a better way to do this).
After all that, it works great!
Found it a bit difficult to replace even with the instructions. Have yet to test it out on the course to see if it all works as before.
