You have found it.
Some facts about the Staton Inc. gear and chain drive kits:
Our 18.75 to 1 gear box has a Life Time Warranty on the Gears. If any gear ever fails we will replace it at no charge. You ship the damaged gear to us and only pay S & H fees back to you. Our gear box is by far the very best quality and very Quiet.
We have current customers who have more than 50,000 + miles on our kits (gear box and rear custom hubs) and they are still running strong since 1984. The Robin - Subaru, Honda, Mitsubishi & Tanaka engines are rated for 600 + hours of use. We have had many of these engine run 2 & 3 times the rating. Engine life in miles. 600 hours @ 30 mph = 18,000 miles. Your engine could get as many as 54,000 miles or more.
Our gear box will never need replaced and it's made to last a Life Time and them some.
We have been building our highest quality gear and chain drive kits since 1984.
Dependant on rider size, riding conditions, sprocket and engine choice a top speed of 30 + mph is easily attainable with a 33.5 cc 1.60 hp engine and we offer many size and brands of quality engines.
Our gear and chain drive bike kits have been used since 1984 in commercial rental fleet without incident.
We use the same heavy duty gear reduction box in our Staton motorized Wheelbarrows and Flat Beds and they too have a Life Time Warranty on the gears. Our wheelbarrows and flat beds are used extensively by contractors to haul loads up to 1,000 lbs. in all types of climates and harsh conditions.
Features of the Staton-Inc. gear and chain drive kit includes the following:
ü The Staton Inc. Engine, custom gear box (made in the USA right here in Oklahoma City, OK) has six high speed double sealed ball bearings, ½” inch thick gears with a Life Time Warranty, a 5/8” output shaft with a 3/16” key way, snap ring grooves to hold the drive sprocket securely in place and a centrifugal clutch.
ü The Staton Inc. custom rear hub, your pick of the 28, 32, 36 and 48 hole sizes. They too are made here in Oklahoma City, Oklahoma to exacting standards in our modern manufacturing facility. Each hub contains four high speed double sealed 12 mm ball bearings mounted to a 10 mm x 1.0 x 7.875” long axle. Each axle, all ball bearings and every component that we manufacture, are made to our exacting specifications.
ü For the left hand side of the hub, we use a left hand threaded 16 tooth freewheel sprocket, for the engine to drive from. The advantage of using left hand thread, to screw the freewheel sprocket onto the hub, is that you drive from all the spokes, and the sprocket remains perfectly centered, at all times. Unlike other kits they "bolt" a sprocket or pulley to 5 to 12 spokes. They are not centered, they pull break and bend spokes then your wheel falls apart. Belts break - hard to change.
We also use our "Inside Drive" gear boxes to drive on the "right" side of the wheel and they can be used with the NuVinci CVP hub that has a 350% ratio that the engine can drive the full range of the hub and you also can pedal the full 350% range of the hub. You can pedal and use the engine at the same time if needed. The NuVinci CVP 350% range hub will give you the low end pulling power to climb very steep hills and still maintain a fast top speed on lever ground. We have used our gear box with the NuVinci hub since Feb. 2007.
ü A perfectly centered sprocket increases performance throughout the entire rpm range as well as reducing noise, vibration and harshness.
ü For the right side of the hub we use standard right hand threads with standard type screw on type freewheel sprockets. Our screw on type freewheels are available in single speed, five, six seven and eight speed varieties. Please note: we do not include a right hand thread on freewheel in our kit. Take your old thread on freewheel off and re use it on our hub or you may want buy a new one.
ü The contents of the standard Staton Inc. gear and chain drive kit includes
One: throttle cable and finger - thumb lever,
One: remote stop switch,
One: Approx 98 links or 49 inches of 410H ½ x 1/8" chain,
One: 410H master links / connecting links
One: 16 or 22 tooth left hand threaded freewheel sprocket, ½ x 1/8. This is a true “freewheel,” it pedals with absolutely no drag while the left side chain remains motionless.
NOTE: As of 2-15-08 We now use ½" pitch x 1/8" wide teeth sprockets for the gear box. You can use a wider chain like the 415 ( ½" pitch x 3/16" width ) or even the #41 ( ½" pitch x ¼" width) and of course the 410H chain that is ½" pitch x 1/8" width. We have used #41 chain with sprockets as thin as 3/32" wide since 1984 without any problems.
We have changed to the thinner 1/8" wide sprockets to “lose some weight”. We also tested the 410H chain over years and it works great.
One: For the gearbox, we include (one) CNC machined B style 410 sprocket that has a ½" wide hub from 8 up to 18 teeth sprocket.
One: Chain and sprocket guard on all gear boxes.
Our Outside drive kits include most all mounting brackets, hardware and instructions.
Our INSIDE drive kits include "most of the mounting brackets, hardware" and instructions for most standard mounts. Note: The new Inside drive kits just released in August 2010.
The NuVinci Gear and chain drive kits have been in service since 2-07 and uses a Inside drive style gear box and it mounts like a Outside drive since it drives on the RIGHT side of the wheel.
We use a 27 tooth 410H sprocket ( ½" pitch x 1/8" width ) on the hub, plus a washer spaces the two chains apart so they do not contact each other. The 27 tooth sprocket and freewheel adaptor will use a standard right hand threaded freewheel sprockets.
The kit comes with a 16 tooth ( ½" x 3/32" ) freewheel for the NuVinci hub, but you can buy other sizes to match your needs - crank size.
The Inside drive gear box comes with a CNC machined adaptor so a freewheel can be installed on the gear box. This allows the gear box to “freewheel” without any drag on the bike. The kit comes with a 16 tooth ( ½" x 1/8" or a ½ x 3/32 ) freewheel, but you can also use a 17, 18, 20 or 22 tooth freewheel to accommodate smaller wheels or to gain more top end speed. We used a standard 26” wheels to design our sprockets and gear ratios around.
The NuVinci kits include most all mounting brackets, hardware and instructions.
ü All our gear boxes are engineered with a centrifugal clutch and feature easy pull starting engines. The gears have a Life Time Warranty.
