The Silk, like the Tikit, puts the BB in the rear portion.
and then ads a chain tension slider, clamp on the back end..
Tikit to use the Belt Splits the rear stay, Silk doesn't have to ..
My Pocket Llama like their other Travel bike has the hinge behind the BB
its part of the main frame Portion..
so My R'off PL has their chain tensioner on the rear derailleur hanger .
You may not worry so much about how it looks, if the Silk gets fitted with A rear Rack,
for your Panniers .. (or at least Mudguards).
Shallow to the company, may not matter if the credit card clears to pay for it.
