Titan Rack Kit, is a freewheel sprocket worth it?

[skyl4rk]

Compared to the bolt on sprocket on the rear wheel spokes, is a freewheel sprocket like the Grubee wheel going to improve the ride quality with my Titan rack kit?

I have to believe that coasting down will be much quieter and smoother.

My spoke mount sprocket is a little off center and it works best when the chain is slightly loose. It is several years old now. It actually works pretty good but you can hear that it is off a bit.

I am just wondering how much benefit there would be to a freewheel sprocket connected directly to the wheel hub.

It sure makes a difference on those occasions when you have to pedal.

There's very little drag. On my cvt because that puppy does have drag I've put on a freewheel sprocket to the jackshaft. It's a 16t. To match it to the 5:1 gearbox you'll need a 16t output sprocket to replace the 10t. But really that 5:1 gearbox leaves little drag you can still pedal the bike quite easily with the engine off. If you really need to pedal long distances like in the off chance you ran out of gas or something you can also just remove the little sprocket that drives the engine to the jackshaft. Loosen the engine bolts,tilt the engine,chain comes right off. Simple side of the road thing.

Is it worth it...........i think so.

I Really Like My Ride Side Drive Titan Cvt Builds With The Free Wheels. You Can Even Let The Engine Idle While You Pedal For The Man. Lol, Ron

Coasting downhile with a DAXTitan rear / rack mount - no freewheel sprocket necessary



Hey, this is a little obvious, but I am going to post it anyway.

If I slow way down at the top of a hill with the throttle completely at idle, then start to coast down the hill, the centrifugal clutch is not engaged, and does not engage - and I can coast at high speed just fine without turning off the engine.

I guess normally, as the engine is reved above idle the clutch pads are engaged with the drum, whetever it is, so that the drum is driving the engine - as long as the bike is moving fast, the pads stay engaged, regardless of how much throttle I am giving the engine.

Not worth it to slow down to "set up" for this for small hills, but sure is for big ones. The only worry is to be SURE not to give the motor any gas when I am coasting, or it will engage, and if I am doing 42 mph it is gonna put some serious torque on the strap.

Hey, maybe I will sell this gizmo on ebay

What are the options for freewheels? My goal is to be able to coast easily when I let off the throttle, or when pedaling with no throttle.

Freewheel on the wheel sprocket
One way bearing on the jackshaft output gear
One way bearing on the jackshaft input gear

Which of these will work?

What are some of the options that work well?

Here would be a complete jackshaft freewheel solution from Staton IF

the jackshaft were 5/8". Dave Staton sent this info to me, it is a 14 tooth freewheel, and a threaded adapater (to be able to mount it on the keyed shaft), and the keyed 5/8" shaft (sold by the inch). This would gear me down (I think) on the input side of the jackshaft considerably, but we have a lot of hills here.

No picture of the shaft, am wondering if the key way would interfere with the bearings ? If they sell it by the inch, does the key way extend the whole length of the shaft, or can you get it just on the end, like you would need ?

Moot point anyway, as at least by my measurement the titan jackshaft is 1/2 ". BUT I am thinking I might be able to drill out the jackshaft bearings to 5/8 " ? Anyone done this ?

I know other people have put freewheels on the jackshaft, but I haven't been able to get anyone to tell me the source for these. Hey, if I find something out about stuff like this, I am pretty good at sharing it...

Here are the Staton links anyway ->

It would be better to have the freewheel on the wheel, so when you're pedaling, you don't have to turn the chain to the motor.

I'm interested in a freewheel that attaches to the 5:1 gearbox as well.

If I'm understanding, the adapter you have found is larger than the 5:1 gearbox's output shaft?? So the only way to connect them is by welding??

I've seen a couple mentions of ways to turn this 5:1 gearbox into a freewheeling output sprocket... but they all just seem to be rumors.
