No but its really just a timing belt and pulleys if you wanted to run a reduction you could make a htd gear fit on the clamshell adapter or on a 6 bolt disc wheel mount. And if you did break a belt you could ride to autozone and get a replacement! Just memorize the belt number. Im thinking of doing one like that with a HT motor I have. Id like to get an old Schwinn and use the disc hub i have to mount a 33/55 t geared pulley. Then id have to make one for the ht output shaft. But if my beta test works i may make a few conversion kits for a lil profit.
