Considerations on parallel drive set-ups

No callback from White yet. I'll call again in the morning. Miles, if you can PM me the file, like before, I'll send it to David, my machinist, to see if he can make it. How hard is it to take one of these ENO freewheels apart?

If White doesn't wana talk business, and your machinist doesn't want the horrible job of cutting inside diameter splines on a small ID hardened part, PM me and we will talk about options. I wana make this slip-on freewheel happen.
 
David can do steel, and get it hardened, so it shouldn't be a problem doing a whole new inner race, as Miles has drawn it. Cutting an existing part would be much harder, I think.

Gary,

I'll do that, but it's not complete, yet - I left off the housings for the pawls. It would be quite an expensive part to make, I think.

The ENO freewheels are easy to take apart but you need the right tools to do it. All the individual parts are available as spares, which is nice.
 
I talked to Doug White finally. He said this is something they could do, but it will require creating a special broach tool, which will cost a couple grand. I asked how many we'd need to order, to make this "doable" and he said "about a hundred...", at the wholesale price of $40 per freewheel. His only real problem right now is time. He's leaving for a trade show in Europe in a few days, and has another big one over here in a few weeks. It'll be about a month before he can get to it. At least he didn't say no. :)
 
At only $40 a pop, I'll take some as long as they can slide all the way onto a splined FW shaft. That way they are reversible without needing LH or RH threads.

I've never examined a splined hub. Are they hollow inside with enough space to fit the axle of a hub motor? If so, I could hack one off of a normal wheel hub and attach it to a hub motor cover, just like I've already done with disk brake mounts and threads for cheap FWs.

Good and bad news i guess.
At $40 a go we need $4000 :shock: good price each though.
i'll take 2 :lol: now we need someone to take the other 98.
realistically is anyone capable of machining them for less?

uuuu tricky. 40$ is a good price. I'll see what I can do to make smaller series. Give me some time ...until Friday.
Miles: can you make plain 2D blueprint? I am not near my home so I do not have any tool.

Hal, this is a custom inner for the ENO freewheels - the model doesn't show all the machining required. $40 is the price for the freewheel with this part (Gary, correct me if this is wrong). There's no way this is even matchable :wink:
 
If we do the deal to spring for the first 100, then whoever the point man is should also get to be sole distributor for White's splined instead of threaded freewheels, because a market will instantly develop. I might be interested in footing the bill on half of the first 100 for that right.

Before, 2 were too expensive - now you can afford 50 :mrgreen: (only joking, John :) )
I'm not keen on monopolies, myself. I see this as being a one off deal to seed the process. Afterwards, anyone can buy them at wholesale price from WI, if they want to become a dealer - or buy them retail.
 
This is very good news, if this happens count me in for 2, If there may be a problem getting a order up for 100 ( which it looks like there wont be ) I know of a couple of cycle trials guys that will chip in ( I was talking to them about this concept today and also think its a very good idea 8) )

Personally almost $100 is too expensive for a FW, but $40 isn't too bad for quality, and I separate business from hobby and am interested in getting into the e-bike business anyway. I wouldn't buy a $3k-$4k pedal bike or the silly priced parts that go on them either, but that wouldn't stop me from selling them to those who will. Plus I think White already does some exclusive production of some parts for distributors.

That's what they say...... Who knows...?

Just make 'em a bit thinner and different hole spacing..... :)

I'd have adapters for keyed shaft use too...and this monopoly would want to be the low price/high quality leader. Prices for bike and ebike stuff disgusts me. :D

John
 
I would be willing to throw $1,000 at this project depending on how far that will go for production.

If we band together, we can get White to make us what we want, I would think.

This is great news! $40/unit is much better than I had imagined it would be for a custom inside race, let alone custom inside race and the whole rest of the freewheel. :) Very good deal!

I will of course be in to buy some. I wish I could go in for a grand like Matt, but I'm "car-poor" at the moment :) I'm sure I will get at least 8 of them though.

Thank you for the leg-work Gary, and thank you Miles for doing the diagrams to ensure the dream RC bike part was indeed possible to fit over the splines.

Today is a great day for all non-hubmotor E-bike builders around the world.

Man, all of a sudden you guys have me excited about this. This is a truely great idea!

Now, how about multiple cogs on one of the two freewheels so the motor does not drive the pedals while running?

You've lost me, Matt :)

They do a 2 cog freewheel - but we already have complete independence...

We might be able to persuade them to do a 3 cog freewheel 8)
