i never had one, but ill admit to ridin the hell out of my friends Sigma.
it was the best for doin sittin down wheelies cuz of that lax seat angle.
when he broke his in half, i got his wheel covers, stickered them up, and rocked those for a while.
they made the koolest sound when they rattled around. i cant explain the sound, but i liked it.
ill also agree...one of the worst bikes ever made, but damned if every other kid didnt want one. wish they had statistics of best selling department store bikes, cuz im sure this one would be right up there at the top next to the Huffy 626, another bike every other had or wanted.
crazy blast from the past! never thought id see a Sigma on G-F, let alone its very own thread. kudos!
