The freewheel is a total loss if you need it removed. You need to unscrew the the outer bearing adjusting plate with a pin tool or a punch and hammer. Then you remove the cog, bearings, springs, and pawls. Then just the body will be left on the hub. Clamp the remaining freewheel body tightly in...

Bikeguy and Amir did an outstanding job building this hub. I am working on a production version of this based on my own hub parts with the Velo Steel coaster brake. Here are a few CAD renderings of the hub:

Re: Sealed bearing coaster brake prototype CAD model of concept hubs based on the Velo Steel project by Guy and Amir.

Re: Sealed bearing coaster brake prototype I could see making a batch of these with flanges to match my own hubs. Probably make my own brake arm, cog, nuts, etc, to fit it into my product line.

Chainring and crank of my own make with large initials in ring:

Here are a couple of images:

Tied and Soldered spokes:

The gold standard in motorcycle front drum brakes is the Yamaha Racing TD2/TD3 270mm 4 leading shoe brake. Spokes are about as long as your pinky finger.

Re: My Rides in and around Boise. Tour de Fat 8-17-13 The Boise Greenbelt along the river is a very nice place to ride. I lived right on it for 9 months while working a contract in Boise.

The steel hub twin leader 8 inch drum brake from the 68-70 650's and later 500's was a really good stopper. They later replaced it with the aluminum shell conical hub that worked like poop, of course then later a mediocre disc brake.

Having never ridden anything but vintage Brit it is all good to me, well almost. I did put that Jap four leading shoe brake on my bike.

Seen that plenty of times on both steel and aluminum cranks. Sometimes it just happens, but in most cases there was some abuse in the past. Often we don't realize that most vintage balloon tire bikes were designed for and sold to children, add decades of riding and maybe some 200 lbs+ riders and...

Re: Sealed bearing coaster brake prototype Huge Compliments and thanks to Amir in Israel for tackling this project for a USA buddy. I could see someone sending Amir a chunk of $$ to get some of this done in batches. Amir has invested a good deal of time and money in tooling and prototyping for...

Dual brake setups have been used on tandems for decades. An internet search should turn up a variety of setups.

My bike (now sold) started life as a 1972 Triumph 500 Daytona that belonged to a good friend. The bike had already been restored as a 1967 which was better looking. The friend had a hot engine in it that blew, he bought a fortune in parts for it and asked to use my shop to put it together. He...

Re: Sealed bearing coaster brake prototype That is smoking HOT!

Here is the brake lever double cable-compensator and double sided drum brake on my own Triumph Cafe Racer:

Quanah; Double sided drums were a standard performance item on fast road bikes (motorcycle) before the advent of disc brakes. The came a two leading shoe, four leading shoe, and in rare cases eight leading shoe. With all that they had the lever and cables all worked out.

If you take a look at the parking brake cables on cars (especially hot rods) you will find a lot of one into two cable systems with adjusters and compensators. Something similar can be created.

Try this double cable setup with compensator. Should be easy to make in a bicycle size. http://www.realclassic.co.uk/techfiles/ ... rsion.html
