Hi, I'm hoping to get a custom seat made, similar to the full length ones Bratstyle made. Can anyone suggest some good ways to secure the seat pan to the bike? The original hinges make the pan too wide so the new one will fit be the same width as the frame rails / loop and I'll be removing the hinges / lock. The person I spoke to about helping me with the build uses a velcro style fastening. What other ways are good? Havent decided yet if the pan will be fibreglass or metal so any options / opinions on either. I'm particularly curious about fibreglass as thats what the Brat ones are made from. Thanks
