Q-Matic drive sytem for 4-stroke motors available $259.75 plus shipping.
The Q-Matic drive can be ordered with 3 different primary ratios, 2.62 X 1, 2.76 X 1, and 2.935 X 1. The Q-Matic employs a wedge belt primary and is trouble free and quiet. The primary belt can easily be changed if different ratios are needed.
The rear sprocket needs to be a 56 tooth [or larger] and the possible final ratios are 14.68 X 1, 15.48 X 1, and 16.43 X 1.
Here are the speeds [MPH] possible under normal operating conditions for both the high RPM [Honda, HS, etc] and low RPM motors [B & S, H.F. Lifan, etc]. The numbers reflect useage on a 26" balloon tire bicycle. 14.68 X 1 @ 7000 RPMs = 36.8 MPH, 15.48 X 1 @ 7000 RPMs = 34.9 MPH, and 16.43 X 1 @ 7000 RPMs = 32.9 MPH. On the low RPM motors the numbers look like this..... 14.68 X 1 @ 4000 RPMs = 21 MPH, 15.48 X 1 @ 4000 RPMs = 19.9 MPH, and 16.43 X 1 = 18.8 MPH.
The Q-Matic is designed to place the ratios in a "real world" scenario to allow the motor to propel the bicycle at a resonable speed without making the motor "sing" at the upper RPM range. An average rider [175 to 225 lbs]on level ground with the stock Q-Matic ratio [15.48 X 1] can cruise at 25 MPH with the motor turning at 5000 RPMs [great average on the High RPM motors such as the Honda GXH50 or the HS 142], and still have good power to climb the average hill. If a rider is heavy or steep hills or both the Q-Matic ratio of 16.43 will yeild a speed of 25 MPH @ 5300 RPMs.
Using the 16.43 X 1 ratio it is possible to reach speeds of 35 MPH @ 7500 RPMs if needed.
Please order the Q-Matic drive from the nearest Authorized EZM dealer.
Have fun,
