Very cool! Whats with the chain tensioners? Are they to avoid the cross braces? I like the idea of scorpion trailing arms. Always figured a trailing arm conversion would be super cool. I like the idea of scorpion arms on a progress gallop frame too.

Not gonna work so great without a middle chain roller. It's going to eat up the cross brace and chain. If it's being sold like this, be prepared for some unhappy customers.

The way it is currently, the angle of the rear upper chain area will chew away the upper plastic "flap" of the gearbox...and even worse, will probably bind if going in reverse. So you'll have to cut off that section of the gearbox. This will also permit dirt to more easily enter it. With the original belt conversion, a tiny gear was added to allow the belt to exit the gearbox pretty much perfectly horizontal. This design looks promising, but it will need more thought to the design. It's not a product that's ready for sale; unhappy customers will be the result.
