I have a v brake on my nightrider and it was really cheap to make it work. The brake itself is just a cheap $10 V-brake and the lever is a mountain bike thumb shifter. Here’s a photo of the beast with the Vbrake attached, and the mount that cost less than $5.00 at the hardware store. I put up a thread a while back but the pix are in the gallery that isn’t functioning. Maybe I’ll re-upload the pix using the attachments function.
