Thanks for the tips. I will give them a try.

I had to sand inside the seat tube a bit for the post to fit. It ended up being such a tight fit, that I don't have a clamp on my post (it just stays stuck), and I wouldn't be able to move it without a lot of trouble. That was because I didn't sand all the way through the seat tube (very hard to do that), so be aware that the suggested tube is a very tight fit.

no sexual innuendos....

Thanks for the photos, do you mind Giving a few cost details for such a build. Interested in price of frame mostly. Looks amazing. I visited greyborg site but his online shop seems to be offline

Probably best to get costs from Zombiess or Accountant. I don't have the numbers handy and things are changing.

Received Pedals and Chain.

Need to package hubs (front and rear) for shipment to wheel builder.

[cassschr1]

Alan, what are you using for the rear freewheel.

[Alan B]

Haven't chosen one. The White is the best, but it appears that it won't screw all the way down. The Dicta has threads all the way through but reviews indicate it isn't as good quality. ACS also may have quality issues.

One concern I have is if the freewheel fails the pedals will start spinning. That would create a major problem at speed.

So I have not decided. I would like to use the White Brothers unit. To get it all the way down might require shortening the threads on the motor. The fully threaded freewheel is the easiest route.

Shortening the 24FET controller

My 24FET controller is about 1/8" too long. The extrusion is longer than it needs to be, so my plan is to shorten it. I was wondering how I was going to clamp it in my small mill to shorten it. Recently I got a 120 tooth 12 inch non ferrous blade for my chop saw. It cuts aluminum like butter. So I think I will use that on the controller extrusion. I'll work up some clamping, but with this blade there is no vibration or noise cutting aluminum. So that's the plan at the moment.

[cassschr1]

can a regular free wheel be disasembled and used ?

[Alan B]

I've never tried to disassemble one. I think they are not easy to take apart, and we need a small cog and narrow width, so the design is likely different.

[cassschr1]

Do you know if 20a pouch cells fit in the frame....how many?

[Alan B]

I have not looked into the dimensions of pouch cells.

[gensem]

If you a carefull you can fit like 24-28 (depending on the clearance you want front the side cover) 20ah a123 pouchs, but be aware that you ll have to bent the cells a little.

That is about 1.5 kwh of A123. Nice.

Is that using both battery storage areas on the frame?

[chroot]

You can ask Luke or ilia, I think they have dud or dead A123 pouch 20Ah and ask them if they could donate you so you can test the fitting measure inside the frame.

Yes, I did some research on that subject a while ago, but decided to test the cromotor before ordering battery for the warp frame.

you can fit 48 hewadways inside ..without bending ....still 1.5 kw

[cassschr1]

Markobetti,can the bending of the cells be avoided by using the wider side covers. Cass

[Alan B]

Decided to go with White Industries 16 tooth ENO freewheel. Ordered.

Will have to deal with the thread depth.

Less costly freewheels are probably fine.

The White product is clearly the best in class.

Freewheel failures are not too common but can result in crashes.

Looking at brakes

The Greyborg standard forks have dual disc capability. So what dual mirrored calipers are available?

Looks like only two. The Gatorbrake 8 pot, and the Magura BIG Twins. Any others??


Freewheels Again

Received the White Industries. It will take an 8mm spacer to avoid having it bottom out on the motor threads. The motor threads are wide. Not sure if this is a problem until the swingarm is together and more measurements are made.

Greyborg told me Hygia does duals that work. I've been wanting to order some Hygia brakes to test them out but have been holding off until I get my own frame and fork because I want the dual fronts. From what I've read the Hygia brakes look pretty nice and are reasonably priced for complete setups. If someone buys them I hope they do a review. I really want to buy a set myself right now just to test them out on my race bike which currently has Hayes Strokers on it, but it's not in my current budget right now.

[Alan B]

Looks like the Hygia Multi for tricycles.

Any suppliers for these?

[gensem]

Hygia sells online for the end user.

I made an order on the dual front brakes like 10 days ago, we they arrive i ll take some pictures.

Excellent. Did you order them with the hall sensor built in?

[Alan B]

Looks like Hygia uses Shimano XT/XTR size pads. Convenient.

They mention something about post mounting. I wonder if they have the proper adapters for the MTB forks.

when you order you select all the options, post mount, iso mount, hose length, adapters, rotor size /etc.
