Check out my chopper show bike. When I ride it, people actually
pause their vehicles on the street to take a look. They're amazed.

Very nice motorized bicycle. What is the tooth count of the rear sprocket, how is the acceleration from a stand still and is the rear wheel 24 inches? Thank you.
 
The ezm q-matic is ratio is 2.5, drive sprocket I believe is 11T and
the rear sprocket is 72T, 26 inch rear wheel with a top speed of
about 32mph. Moves from a stand still with ease, accelerates
aggressively and smoothly, the most powerful combination I have with a
modded carb and 7/8 inch ID flexible exhaust. The q-matic
makes the bike feel like it has an automatic transmission, as
the drives slips until about 12mph.
 
Is it the EZM designed Max Torque clutch on the output shaft of the transmission that slips? I don’t think it’s the v-belt, that belt tensioner is very strong. I am running a 77 tooth rear sprocket, because my pedals don’t turn 360 degrees, and I bought that from Pirate Cycles back in the day. I didn’t realize why my transmission was so smooth from a stand still. Thanks you for that information. I think Justin Troy ordered my sprocket through SportsmanFlyer because at the time I was talking to him he said that he was no longer ordering sprockets from Manic Mechanic. My rear sprocket is high quality. Say, where did you order your sprocket from. I’m just curious. Thank you for the reply. My EZM drive with the 142F has been bulletproof for a few thousand miles now. Never one problem after I switched to the balanced pulley on the output shaft. I haven’t ridden it for years because I switched to a properly built 212cc bicycle and my retirement has not turned out the way I expected, I am very busy. I appreciate your insightful reply.
 
The 72T rear sprocket is no longer available, and now EZM
offers their pacesetter q-matic which has a higher gear
ratio for smaller rear wheel sprockets. You're looking at
a 1st generation q-matic. The bicycle is also no longer
in production. I bought the last model off the production
line. It's called a Deviate Micargi chopper.
 
Hey dude. Could I have a couple minutes of your time? What specifically within the q-matic drive train slips that “… makes the bike feel like it has an automatic transmission, …”?
