This is from June 2008 so I can't verify that it's still valid and it refers to the Tikit...I assume the other BF travel bikes like the NWT can be made even stronger:



Hey Vik, here is some data for your torture testing.

"All of our tikits can be built with riders up to 260#. Above the 260# limit, we need to review the design and frame materials. We would need to know your weight in order to properly design the frame. Costs are $50 for the heavy rider upgrade to 260#, most likely an additional $50-100 above this weight limit."
