I received an e-mail from David Staton about a new product that sounds exciting. Said he was waiting for parts to get back from the platers before he broke the news. Anyone else heard anything?
Here is something else I found on the Staton site.http://www.staton-inc.com/store/products/3_Speed_Shift_kit_for_the_OUTSIDE_Gear_Chain_Drive_Kits-1000-15.html

The 3 gear shifter is listed for the outside chain drive. Its not clear from the description as to how the shifter will work. I have an inside drive and David claims he will also have an upgrade 3 gear shifter kit for that. I was planning on rigging a chain from my Staton gear box to the crank/pedal sprocket when I discovered his upgrade. I'll wait and see how it plays out with his upgrade kit. Maybe 3 gears is enough?

If the gears are spread evenly, three gears are enough. I have 8-speed, usually use six, sometimes skip every other, so three or four.
Gear ratio around 30.5 for 1st, 16:1 for third, depending on engine's powerband.
Can you say 3-speed derailleur?

to Reb1, I run a tandem bike. I have the Staton chain drive kit. My photos are not yet posted on his site of my bike.
I wanted to make a comment regarding your decision about these kits. It is related to the topic because it involves the possibility of needing the extra gears.
I seen Statons latest developments. The 2 or 3 speed for outside drive kits. From the pictures, it doesn't look good to me "unless" we can get way lower gearing ! He's showing a 16 tooth on the small gear ! I have a 11 tooth on the top now and its a pretty good gear for slow speed. It has a lot of torque right from the start. You really don't have to pedal assist starts that low. I still do. But at cruise speed with an 11 you are really limited. I never got around to check my cruise speed with the GPS yet. But its slow from my experience and judgment. I did a gear ratio check to see what single gear would be more median than the 11 tooth. I come up with a 14 would be about right with my current engine the Tanaka 40cc. But Staton has these on back order for a long time and I haven't got it yet. So I am about to try the 13 which is close. I also have the 15 to try now but I only anticipate that would be for solo riding. I can't imagine trying a 16 or on up. I think that's too high unless that pictured gear is intended for maybe a smaller wheel. I have 26 inch wheels. I think Staton will get the right gears as soon as he's ready to release that kit though.
I ordered the outside chain drive and then about the time I had received the kit at home. I was reading over the Staton website and only then did I discover the NuVinci kit. But I soon discovered that the NuVinci kit only works with the "inside drive" and I now had the "outside drive" kit. I really need more than a single speed and I sure wished I had known about the other option. Now, I really do not have extra money laying around and it's sure gonna sting to start over purchasing another kit. Lucky I can get a small discount because I can buy the kit less the engine. But if you run strictly flat areas, a single speed might be OK. But running with two persons on the bike, I need low gears to climb big hills and also for slow putting around cities when around people. I need the big gears to take advantage of the downhills and flats in the rural areas.
I'm about to order the NuVinci soon. I think it might be better in the long run over these added gears.

I have an old ankle injury that only acts up when I ride the tandem with the wife. I am thinking that a one speed would work if I can get it in a range for the hills. I ride the tandem mostly by myself and pedal all the time. Staton has a gear box setup where you can hook it up to a crank also. http://www.staton-inc.com/store/products/24_speed_Shifting_with_the_engine_and_peddling-994-15.html

Gonna be interesting to see what he came up with because I emailed him pictures of my design for a two speed back in 08.

There is a two speed setup he uses for three wheelers also. http://www.staton-inc.com/store/products/PAV3_Two_Speed_Honda_GXH50_Four_Cycle_Engine_Kit-961-28.html

I saw this last night. I can't tell from the description if this a shift on the fly type sprocket? Maybe you move the chain over manually to get the desired gear power ratio? Hopefully more information will follow later this month.
