CCM Folder Cargo Bike Project

As promised earlier, here is this year's bike build project. Hopefully it won't fight me like last year's build that actually got a win over me. That bike will be revisited maybe in the coming years.

U-245 Hammerfish Bike, the starting point.

For now, a need has risen for a small cargo bike that can carry my 4X5 camera and tripod. That gear weighs over 20 pounds all together and I don't want to kill myself carrying it around the City. The folder bike is small so it can be stowed in the car on trips and the low centre of gravity means my camera stuff won't be falling from too high if I crash. Always plan for the worst!

One piece crank to 3 piece crank conversion kit.
The original bike was a coaster brake one speed CCM folder bike from 1976. Hills here in Montreal are not made for that set-up, so I'll be going for a multi speed hub with derailleur. I'll probably be replacing the one piece crank with a  3 piece bottom bracket using a conversion kit I bought some time ago. This and the aluminum rims I'll be using will help save some weight. The gear I will carry and the custom carriers I'll have to fabricate will be on the heavy side.

Aluminum rims and high pressure Maxxis Hookworms will be taking care of rolling duties.
The bike is entered in the annual bike build off contest at ratrodbikes.com and I intend to go with a U-Boat theme. However, since I'm modifying a lot of things, I need to proof concept the bike before I paint and start customizing. That means building it to ridable condition to make sure everything works right before I do all the fancy stuff.

1958 Brooks B66 saddle, still good and very comfortable.
First off, I have to dig thru my parts pile to find all the bits that were scaterred here and there when I took this bike apart some years ago. Keep posted.

Don't forget to check out the how-to articles.

Until next week, ride safe and free.

Gerry :)

You're absolutely right but I'm real lazy. :(
