OK we're on schedule w/ the production of the WhisperDrive! The first run is going to be of limited quantities and on a pre-reserve basis. To avoid over/under production, customers who'd like to reserve their Whisper Drive 4 stroke Bicycle Motor Kit can place a refundable deposit of $50 and place themselves on the list. We'd be foolish not to make a few extra, but don't count on it, reserve yours now! We'll be compiling the list for a week or so at which point we'll start production. Turn around should be quick (just a couple weeks) and people should start seeing their kits in the 1st wk of May. For now, customers will supply their own motor; the Harbor Freight, Lifan etc 3600-5000 rpm motors will work w/ this system (motors other than HF 79cc 2.5hp and Lifan 97cc 2.5hp could require modification of mounting holes) The Production Model will be Upgraded w/ an Automatic Belt Tensioner At $440 (+sh) The kit will include: The WhisperDrive 4 stroke Drive System, Universal Motor Mount, Straight Pipe Exhaust, Throttle Conversion Assembly, Final Drive Chain, Rag Joint Sprocket and Wide Cranks. At $540 (+sh) All of the above w/ HD MotorBicycle rear Wheel (Grubee hd axle fw sprocket hub w/ hd spokes, alloy rim and band brake).
